So I bought an ebay chip and got it today, When I opened up the ECU to my surprise I found a legit Dinan Chip, I was pretty stoked. So my question is to you, what chip should I use in my car. The ebay chip or the Dinan. Does anyone know the specs on the Dinan? The ebay chip claims +22hp, and +20lb/ft(which is obvously inflated). Thanks, Preston.

The eBay chip might as well claim 200hp gain. If it's not a MarkD or a MarkD rip off then I'd go with the chip you have. I guess you could try them, but I'm a little worried about eBay chips personally.
-
The Dinan chip does around 17 hp and 20 hp increase. I'm not sure about the chips on eBay and I'm swayed from the numbers claimed by them. I would suggest putting in a Mark D chip or keeping the Dinan chip. Alpina chips are amazing... If you can find one... +24 hp +25 TQ If you want to get rid of the Dinan chip pm me...

Hi Preston,
I'm curious what your eBay chip actually is. If you can lend it to me for a few days I'll ananyse it and tell you what it is, if it's got a copyright notice in it. I'll also report back on whether or not it looks like the maps are good.
Thanks,
MarkD

I'm curious too.
About 2 years ago I got given a "Euro Group N" chip for the M42, that a mate bought off ebay just before he sold his car. I haven't got round to trying it on a Dyno to see what difference there is from a standard chip.
I would be very cautious of anyone advertising over a 10hp without "backup" like dyno sheets (especially independant ones).
MarkD - is there an easy way to find out if a chip is any good without putting the car on a dyno?
Thanks
Cristian

Hey, Ya PM me about it, but the only problem is I'm leaving for a few weeks on July 7th, so if you PM me quickly I can ship it out before then. I'm pretty sure it doesn't have a copyright it just says 1990-1991 BMW E30 318is chip on it. I would buy one of your chips, but I don't have the money right now. Maybe in a few months! -Preston
Also I put the Dinan in my dads car.

You're going to see 3-5 hp at best when chipping these cars. Probably less with a 91 ocatane Dinan chip. It's still worth it, but don't expect miracles. These are hard engines to get power out of without internal work or forced induction.
-
Mines custom made on a blank chip. Should give +9kW +11hp +600 rpm limiter. Theres a noticeable difference from the 4500 rpm and up all the way to 7300 rpm.
John W i think you are wrong actually. M42 is limited (downgraded) by the stock chip from factory and is not using its full potential at all. I should ofcourse do a dyno run on mine. :P
-
Heres my proof. :D Before and after chip install.

I dont believe in any numbers you say until you prove it. :)
-
Personally, go with a MarkD or Jim Conforti chip, or none at all. Other than that I would definitely avoid eBay chips.
-
Kinda limited on your poll choices. Mark D's chip is my choice.
If it's just between ebay and Dinian I think the choice is obvious if you are not budget constrained

3 to 5 hp? It wouldn't be worth putting in a chip if that's all you get. Ask the people that use my chip if there's only an extra 5 ponies.

didn't realize u already had the dinnan, the ebay chips are generally the same as the dinnan ones.
if cost is no issue though, i would go with a mark d.
-
Ebay "ProFormance" chip worked fine for me... they are all copies of other chips I believe, which ones I have no idea... but copies for sure. I haven't dyno'd mine yet with the ebay chip, but with the Mark D one (borrowed from a friend) I got +6rwhp and +4ft/lbs over stock. This is with the car running lean though probably do to an exhaust leak and/or the combo of my delta regrind cams.
-
im running a Jim Conforti Chip and it claims 15hp and around the same torque. It really throws more power out between 3-5000rpms and bumps the redline to 7K. Noticably more power when gunning it from 3rd to 4th gear around the 5-6Krpm.
-
where would you get a mark D chip?? thanks

I got mine from JET CHIP.
I deff noticed a differance and the company make u send out your ECU wich sucks if its your daily. I got mine back in about a week. They ask you your mods and tune to that. The chip is sposed to produce any were from 12 to 20 hp depending on prior modification to your car. I want to say I gained about 15+ with exhaust and intake when i got it. The only down side is that its about $360.00 and puts u out of comision.

To be honest, I bought a "dinan" chip off eBay as well (stupid not to figure out it was just a copy) but it should deliver just the same gains as the actual Dinan chip.
If you can't tell which one its a knockoff of, Mark would definately be able to help you.
On the side of a chip, Mark's is one of the best (especially if you can get good 93 octane gas, as his 93 octane chip for the M42 is supposed to be AWESOME). I would not recommend anyone buying a chip off eBay, I was living in a fools paradise thinking they were actually legit. Albiet they probably work fine and mine has had no problems, you aren't supporting the person or company that spent their time, expertise and hard earned money developing these chips. Intellectual Property should not be devalued just because its easy to copy software :)
And yes, chipping a M42 from stock will undoubtedly produce more than 5hp or whatever JohnW quoted. BMW still does have a marketing department that wants to make sure there is enough of an incentive to spend the extra money on a 325i, let alone keep tight emissions, etc that get relaxed when doodling with chips. They have to keep enough room performancewise between the models. I think MarkD even provided some input :)

Well I just blew $40 on a "proformance" ebay chip and installed it in my spare ECU (see signature). As soon as I run through this tank of 87 octane, I'll fill it up with 91 and swap ECUs. Dynolicious will reveal all.
As to the original question. Try both, see which one blows up your engine first. Go with the other one.

Will be great to check out and see what you got!
