Alright, so yesterday on a damp Norcal day, I went ahead and installed my "fleebay" chip as some call them. Before I installed it though, I went ahead and did some 0-60 runs to see if that would be affected.
NOTE: Both in-car shots are with a 140lb friend holding the camera
STOCK CHIP:
To my amazement, with the STOCK chip, I was consistently doing 7.2ish-7.7ish runs. My car is fairly stock, with the exception of the 3.91 diff and maganflow catback. I believe the 3.91 really helped the 0-60 time because I shift into 3rd at 60, w/stock chip, instead of 52ish? with a 4.10. Ok, so now the good stuff. In this particular vid, the road was beginning to dry up and I shifted exactly at 6500rpm(right at the rev limit). You will see that at 7.5 secs I'm doing 60:

In the following vid, if one begins time from my launch till I shift, approx 7 secs:

AND NOW CHIPPED:
First of all, I would like to say that this chip is AWESOME! Rev limit is now at 7000, as expected. But the difference in pull from 4k is VERY noticeable. The car idles SOOOO smooth. It idled fine before, but now it's crazy smooth. The first thing I noticed was how the over all responsiveness of the car improved . It feels much, for lack of a different word, smoother. Also, I noticed a very interesting thing. At idle, "normal" driving, and freeway cruising, the car is very quiet. My magnaflow was relatively loud, but now has mellowed out. But, under WOT, it's much throatier and sounds fantastic!
Alright, now for the "after" vid. Unfortunately, the rain came. And boy did it come. When I shot this vid it was raining lighty and I could no longer launch at 3000ish for obvious reasons. As you can see, I launched at a measly 2k. BUT...I still managed to do 60 in 7 seconds. Yes, and in very wet conditions. So, I'm expecting at least a second off my 0-60 in ideal conditions! I hit 60 at around 6800rpm (maybe 6700,I can't really tell):

PS I hope the vids work. They were giving me problems earlier. If they don't please let me know of another place that can host them for me (us ;)). Cheers.

So what you're saying is that you're doing that quick of runs without a lightened flywheel?
Well I'm certainly suprised. Makes me honestly consider getting a new rear end. Now I wonder what the runs would be like with a new flywheel and a new rear with a chip and exhaust. I imagine you could duck into high 14s in the quarter or maybe low 15s.
-
Isn't it wild? I was thinking with a flywheel, I'll be doing high 5's very low 6's (0-60)!!!
Here's my mod list (performance oriented):
Magnaflow catback exhaust
3.91 Diff
IInd Gen Pro Formance chip
and for shits and giggles, I removed the plastic panel that covers the back of the driver's side headlight assembly.<----Little bit of ram air:p
-
so a 3.91 rear end will improve accelaration? wouldn't a 4.27 be quicker?
i always get confused with these ratio's

I think he's saying that with a stock redline, you cant hit 60mph in 2nd gear unless you change the gearing. A shift to 3rd slows you down.
-
Sounds great,
I know I did get a funny feeling in my tummy looking at my SMT unit at the garage today, also the wideband controller I have,
I will be installing the SMT soon :)
I shall beat your times hehe,
but I canīt rev as high but will let 6500 do

:D not quite. If so, to hell with motor swaps and boosting projects.

:D not quite. If so, to hell with motor swaps and boosting projects.
to hell with motor swaps unless they involve an m42 going in:) i'm hoping to undertake building a 2L or 2.1L boosted m42 this summer, or atleast start building one... i doubt ill have the money to complete it this summer.
-
I am not saying that's the way to go, I am saying there's no way to simply get the car to do those hopeful 0-60 times with this intended mods :)
-
I think the M42 can be made to be very powerfull with boost,
I mean subarus in 2.0 trim are running upwards of 800hp these days
-
I think he's saying that with a stock redline, you cant hit 60mph in 2nd gear unless you change the gearing. A shift to 3rd slows you down.
^^^^Exactly.
e9nine--I know it sounds rather optimistic, but considering Gunni's car is doing similar times to my car with nothing but a lightened flywheel, I imagine I can at the very least shave 1/2 a second off. Who knows, I'll definitely share my results when I "slap one on there."
Gunni--Yeah, as far as potential goes, I believe we've got something going with our engines, but not many people have gone beyond a S/C on our cars.
Vids work OK for y'all?
-
If you don't mind me asking, where did you pick up a 3.91 from and were there any fitment problems? I heard you can do the swap in about an hour if you got the right tools.
I would love to get pointed in the right direction on this. What models came with a 3.91?
-
3.91 diffs came in the manual e30 318i. As far as locating one, go to your local pick-a-part/junk yard and you should be able to locate one easily. 318i's(not "is" but i's plural) are a dime a dozen. Keep in mind that the 4.10 is a closer ratio and will give you better access the top end power at higher speed. The 3.91 gives you better 0-60 acceleration, though. This is because one shifts into 3rd at 60mph (59.5ish if you will) when using the 3.91 As opposed to the 4.10, where one has to shift before 60, killing acceleration time. Also, I love the 3.91 because one gets better gas mileage, as well as a quiter ride while cruising on the freeway(due to lower revs). Let's not forget a "theoretcaly" higher top speed. :p
-
I can hit 60 in 2nd with my 4.10
Never timed myself though.
-
Really. You are the first person I've ever heard do this. This is from BP's site:
A quick retest (at night though, so no video pics) with the Superchip installed has indicated that, with a good start, a run in the low-to-mid 8's is possible. Click here for the sound file link. Pause the file at the gear changes which were at 6500rpm. 2nd equates to slightly under 55mph in ~6.5 seconds and 3rd equates to ~83mph in ~12.5seconds (true values). I would approximate 60mph to come up in a little over 8 seconds.
Interesting. You got a MarkD chip right? You should time it and see how you do.
-
Excuse: Sig testing...
-
definitely need 3rd gear to hit 100kmh with my 4.10 and standard redline.
i have located a diff cover for my new diff (3.91), so that will be going in soon.
what i am trying to do is get a hold of a G-Tech through a mates work, and i'd like to reference some 0-100k times with both the 4.10 and the 3.91.
I will keep you guys posted.

Wait.. I have a 91 318i. I was pretty sure I had a 4.10 rear end though.. What year are you talking about? I get around around 30+ mpg already. I guess the only way to check is try to scream 2nd out to 60 today.
-

225/50/15 tires with a Mark D chip. Taller tires and 7100 limit are what does the trick.
-
Minkee--Sorry, I should have been a little more explicit. I was referring to the older m10 powered 318i. As far as gas mileage, try close to 40mpg freeway;) . I get 30mpg cruising around 80mph.
-
2002maniac--Hmmm...the diameter of your wheel/tire combo is not much different from mine, but the circumference is. I guess that's the key here, huh.
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference

Hey, did you guys end up doing the rota group buy? I think grids look uber hot on e30's. I'm really contemplating on getting some 16'' in gunmetal. Probably not making it for the group buy though.
NOTE: Ahhhh, i just realized what you meant. you can hit 60 with a 4.10 because you have a chip. Yeah, of course. I was just referring to the stock redline and 4.10.
-
Hrm. I've been thinking about a chip lately. Read an article in GRM that the stock chip was running the engine on the lean side, and then after putting in the chip they bought, it was closer to prefered ratios. But the damn thing was too expensive.
How much did you pay for yours? What was the ebay sale title (so I can find another one on ebay)?
thanx
-
Close to nothing!!:D The seller's name is sapporo10. Very good communication and awesome chip. I won't tell you the price. Look it up and be amazed at how inexpensive his chips are. Very good deal. Keep in mind that a lot of the ebay chips are replicas/spin-offs of the popular name brand ones out there.
-
i tried to hit 60 in 2nd gear w/ my TMS chip the other day and got to about 58 at 6900rpm and shifted. i could maybe sqeeze in 60mph but it would be very close and i would have to shift right on the money. im drifting towards the 3.91 diff swap idea, but i love autox and i'm afraid i won't like the lower diff staying in 3rd gear.

It's easy with the programming tool to copy another chip. It's a lot easier than doing research. Of course there's that "intellectual property" thing. It's like the joke:
Q: How many copies of Windows did Bill Gates sell in China.
A: Two - the second guy didn't know the first one already had it!
-
jfdublyu--Interesting. I guess I'll keep my 3.91 for the daily haul and swap in the 4.10 for autocross/track days. I'm still waiting for a response from the dude selling his 4.27. I guess you eitherhave to go really close, 4.27; less than the 4.10, 3.91, in order to get good 0-60 times. But, the closer the gearing is definitely better for autox/track.
D.clay--Funny, due to that, an agreement was reached recently that several Chinese companies will install windows software from the factory like they do here.

I bought one of the Pro Formance chips off ebay last week and it arrived last night; I'm in Aus and because I never bothered to set up a PayPal account I got my mate to buy it for me cos he had. After it arrived he calls me up and tells me not to worry about paying him cos he was giving to me as a birthday present. Jezza: 1, World: 0.
So I go over his place and the we had the chip in and the car running in under 20 mins. Jezza: 2, World: 0.
I pulled out of his garage and IMMEDIATELY noticed it performed better in first. Jezza: 3, World: 0.
I pulled out of his street onto a wide main road. Every time I make this turn I swing out my rear end. Today was no different however there was definately more power because doing the same sequence I always do and the change into second pushed the rear out further than it normally does. Jezza: 4, World: 0.
Next set of lights I did a 3k dump to see how fast it got to 100km/h. The shift from first to second was orgasmic. Because the engines goes to 7k now the gearing means the shift into second leaves me right in the thick of the power band and the rear end was saying "hi, don't forget about me :P~~" in the change to second. Also, I think it got to 100km/h in 2nd; if not, very close. Jezza: 5, World: 0.
"Lets go teach some ricers a lesson" says my friend in the car. I oblige, quite eagerly :)...
Victim 1: Riced up new Toyota Corolla - 2nd gear rolling start. Fairly convincing beat, but that was to be expected.
Victim 2: Mitsubishi FTO - 2nd gear rolling start. He had an initial lead but the extra high end power coupled with the extra 500rpm meant I ended up taking him.
Victim 3: Skyline R32 GTS-4 - Set of ights. I figured this guy would rip me a new one but I wanted to run him for the pure fun of it. 3.5k dump and I killed him off the line then he backed out! He was boosting like it was on sale for $1 but just didnt get off the line. At the next set of lights he winds down his window and asks me if I have a turbo ! Jezza: 6, World: -1.
So to sum up, the chip increased the rev limit so I don't have to change as early and when I do I shift into ~4.5k, seems to have increased torque and theres a marked difference above 5.5k. Plus maybe I can squeeze 100km/h out of second.
All in all; best birthday present ever! I whole-heartedly endorse this product and/or service!
-
i just installed an ebay chip for my buddy on his 89 325i. it's official, whoever is making copies and selling them on ebay is doing one heck of a job!
-
is there any evidence of a pro formance chip doing anything bad to the engine? if not, for the price of dinner and a movie oyu can get a decent chip... not bad.
speaking of boost and 0-60 times, small engines can rock. my wrx is 2 liters and i can get 60 in 4.8ish.
-
so ha there been any evidence of detrimental effects on the egine with these pro formance chips? like anything reported on quality control as far as bad ones or anything? because from what i hear, they seem like a decent chip, especially for the price of dinner and a movie.
speaking of boost, small engines can rock. my 2 liter wrx can hit 0-60 in 4.8ish.
-
I did a search on ebay for pro formance and couldn't find it. Any one have a link or a seller id?
-
Seller id is sapporo10 but doesn't appear to be selling any for e30 318iS at the moment.
Pre-chip I almost exclusively ran my car on 98RON fuel; regular has been going around $1.20-1.35/L and the cost of 98RON is always $0.10 more than whatever regular unleaded costs. This means that its always less than 10% extra but I noticed a decrease in fuel consumption of more than 10%.
However recently I didn't have much cash on me and I filled up with regular unleaded (knowing that the "octane rating" was going to be "minimum 91"). The ProFormance chip stated to use fuel with 91 or higher octane rating.
I noticed the car knocked at low revs under load so I researched octane ratings and found that the fuel I'm using is rated waaaay too low for the tuning of the chip.
The different octane ratings between US and Australia are that the US uses the AKI which is RON+MON/2 and Australia uses just the RON. MON is "generally 8 to 10 less than RON" so 98+88/2 = 93/94 US octane rating.
I didn't know this at the time and hope that there hasn't been any damage.
I'd say if you make sure you NEVER use fuel less than the specified rating and you should be okay. I'd heard all this garbage about US fuel being poorer quality than Australian fuel, obviously propagated by people who didn't realise the difference in octane rating systems between the companies which is why it never even crossed my mind that this might be the wrong fuel to put in.
I thought the fuel I was putting was a-okay; I was wrong :(
I'm driving it really carefully at the moment, keeping revs higher to keep cylinder pressure down but I still get a knock every now and then. Is this going to cause major damage?

Maybe put in a bottle of octane booster to be on the safe side???

You are not really accelerating faster with the new rear, you are just skipping a shift. It "should" feel slightly slower but get to 6 just a tad sooner. That little amount is debateable though.
As for hitting 60 in a 4:10 car in second with stock size tires (or close), unless you rev to 7200, it will simply NOT happen. It will look like it though.
One thing for you guys getting great 0-60 times, PLEASE keep in mind, your speedo is off by almost 10%. That means at 60, you are actually doing 54mph. On 195/60r14 it is exactly 10%. Do yourself a favor and get someone with a GPS and figure out exactly how far off your speedo is.
This is why we have people claiming they got a 318 up to 145mph. It simply cannot do it. With stock chip and tires the car redlines at 133mmph regardless of what your speedo says.
2002Maniac at 7100 you will be doing 62mph.
-
Grippy, you claim a 0-60 time of 7 seconds with the ecu, 7.5~ without. That is pretty impressive regardless but it seems too fast to me...
Have you had your speedo recalibrated for the new diff and for your wheels/tires? The diff would put you 5% lower, the speedo is already about 5% lower from the factory and tires maybe another 5%. That means 60mph on your speedo could be just over 50mph in reality.
Not having a stab at you, but if you haven't done any recalibration then your figures don't mean much. According to tests where 0-60mph (speedo claiming 63mph) was completed in 9.3 seconds, 50mph was reached in 6.5 seconds.
-
Can chips wreck your engine at all?
-
okay, i think i am about to order one of these for my car. Dino and Thumper3ed claim the chip is worthless in an older thread, but all of the people who have it swear by its effectiveness, maybe not compared to the markD but at 35 bucks.....
-
Yes I bought one off sapporo a couple of years ago for my 320i (E36).
Due to the unusual DME on these he was kind enough to work back and forth until we had the right combination of power and economy.
Now that I have finally replaced my catalytic converter... OMG soo much more torque has been unleashed.
Remember. After changing the chip wait around 100 to 200 miles for the ECU to relearns.. then you will be at full power.
