Im really excited about this. Here is my plan. I have the original stock DME, I plan on doing the first run on it, it only takes about 1 minute to switch them.

I will swap the "Chipped" DME for the second and third runs. That will give all of us some info that we would like to see. A real, concrete, accurate test.

Or I could just do the first and second runs on the new chip, and the last on the stock, that would probablly work out better....

First one I have ever been able to do, so I'm pretty excited. My a$$ says I got an good 10+ HP, so this wil tell me if my senses have been correct my whole life or if Im one of "Those" guys who gets More HP from an oil change!LOL!

The place Im going is Dyno Lab in Marietta GA. Arthur is a nice guy and has thursday night specials 5-10pm. 3 runs for $50...you cant beat that.

So, Ill head out after work.

I will post the results as soon as I get back home, I will have to figure out how to scan the results and then post them, which I have nevver been able to do.

CHeers and beers

If you think a chip will give 18-20hp i'm sorry to say but you're off the hook. Maybe 5-10hp max from a cip.

I would actually be surprised to see consistent, reliable dyno results showing more than 3-4 peak hp over an M42 powered car that is already properly tuned. Chips are a great upgrade that improve drivability, raise the rev limit, and show gains across the top half of the powerband, but the hp gain is minimal at best.

Man, from experience, I agree. HP claims are always BS. Thats why I was happy to notice "something". Like homeboy said, and I agree, "Even a 5 HP increase is worth $50". I would be happy with 5, but I really think it's a little more.

I would be REALLY suprised if it was what it claimed, I knew going into a chip to realistically expect 1/4 or so of the claimed HP.

Is there anyone on the board who has chipped their car? have any results to back up any claims? I cant be the first?

Tomorrow nights the test of truth!

I'm definitely interested to see the results. And I do agree that chips are a must (unless you're racing in a class that rules it out) for these cars. I just view it as the last step of a major tune-up -- not a source of major horsepower gains. I installed Mark D 93 octane chip last month and feel it was worth every penny.

What do you consider a major tune up? Like I said earlier, This is my first computerized car, I'm used to a "tune" actually squeezing more hp, like on my old 530, I had plugs, jets(webers), timing, adjustabe cam sprocket...all stuff I could fiddle with to get another HP.

BUT, Now I own a computerized E36, aside from a chip and trying out some different plugs and stuff, what else can I do? What else is there that I can fine tune?

Any advice would be great....

peace and grease

I purchased my car a couple of months ago. It ran very well, but I went ahead and did the following: fuel filter, new plugs, Magnecor wires, K&N drop in air filter, synthetic oil. Then I added the chip. I should also put synthetic ATF in the tranny and syn. in the diff*. I didn't change the 02 sensor as the car runs well and gets good gas mileage.

*Grassroots Motorsports did a project series on a then-new 318ti in the late 90s. They switched out all of the fluids for synthetics. Although they gained less than 1 hp peak, they picked up 5 hp at 4200 rpm. A good investment in my opinion. They also picked up 1.5 hp by switching to Magnecor wires (remember, the wires they replaced were new). More recently they did a 318is project series and picked up 6hp just by switching out the wires (obviously the wires they discarded were not functioning well). That article can be found here:

Thats the kind of info I need. Right now Im using some "questionable plug wires" and dino oil. I was thinking of going to syn. I have a 94 low mileage motor I just put in it.

As for the tranny, you stated ATF, are you running an auto? Is there a recomdation for 5 speed gearbox? I just put new dif oil in, so Im good there.

In a fairlane, when you have a 390/406 with dual quads and 390HP, 10-20 hp and better wires dont do much, and I could care less, but in 140 HP car, where the options are limited as far as cheap reliable HP, I'll take every single little HP I can get...

The 5 speed manual also takes ATF. To be sure theres a big sticker under the bell housing indicating what kind of oil to use.

I'm very pleasantly surprised to hear hp gains from wires. I've always thought this was BS. But now thinking back to my other interest, hifi, I certainly know that wires have a huge impact on sound, so why not spark. Seems like wires have been added to the list

Can't wait to hear the results tomorrow!

I am really curious to see the results of the dino as well. In addition to the Pro Formance chip there are several others on eBay (search "e30 chip") that are unbelievably inexpensive. I am more interested in looking at how the torque/hp curves compare to stock than the max HP gain.

Do you guys think these guys are selling Dinan/MarkD/Conforti/BMP clones or do you think they have created their own chip?

AAAAAHHHHHHHHHHHHHHHHHHHHHHHAAAAAAAAHAAAAAAAAA!!!!

Oh man, what a shock!

1st, can I email someone a file so they can resize it and post it, seeing as how I cant figure it out?

2nd, I have just got beck from the DYNO. Im impressed with this car, but not so much the chip.

I decided to run the first two runs with the chipped DME, then the last one with the stock DME...

First Run, 121.3 at 6000RPM, I didnt want to rev the shit out of it.

Second Run, 122.4 at 6300 RPM, I didnt want rev the shit out of it.

Third Run and this is the kicker, stock DME, 118.9 at 6900 RPM, I revved the shit out of it looking for the rev limiter...

MAx torque was 109.6

So, the chip got me around four HP. Im defiently gonna let James know, maybe he can do something. We'll see. HArd to believe that much HP makes the car feel a little quicker though.

Cheers and Beers

I thought stock redline was at 6500rpm. Seems odd that it let you rev all the way to 6900. I wouldn't be disappointed in this chip. It moved peak HP down in the rev range to a more usable 6300rpm. If we had both before and after graphs we would probably see a nice torque increase throughout the rev range. To me mid range torque is far more important than peak power.

Thanks for posting these numbers. Looks like the chip did what it was supposed to do. Overall, the numbers look pretty good. If you account for a 15 percent driveline loss, you're making 140.76 hp at the crank (using your dyno best of 122.4 hp). Not bad considering a stock, but brand new e36 with an m42 was rated at 138hp from the factory.

IM happy, the cars scoots!

It's one of those cars that you can drive the shit out of! I was hoping the final printout would have all three runs on it, but it didnt. So, I might be off by a small bit on that info,I had to look at the readout a from a few feet away and squint, and remember it.

Im still happy with how it runs, and I still wan to email James with the info, just to see hwat his take is on it. I lost my laptop at the house to a virus or something so my access is spotty right now...

The guy in the photo is Hari, a guys from bimmerforums testing his 92 535, it made 188 rwhp, and it was built to the hilt. At one time he was making 199 to the wheels. He was impresse with the m42's performance.
