Picked up and Installed my JimC Chip

[M42Technik]

What are the gains w/ a M42 motor?

on TMS's website it says 12hp/16ft-llbs

Wow I thought it was 10hp/11ft-lbs.

Anyone know where i can find a dyno comparison for the jc chip?

I'm sure its about half of either of those. For my 325i it didnt make too much of a difference, but then again its automatic. I guess my E28 535i will have to suffice now :D

Mine is a 325i as well but 5spd and i can notice a huge difference. It's real nice

I emailed Jim. For his friend's 325is, he said he remembered HP gain at peak was ~10, so it moved the curve from 167hp to 177hp, similar with torque, ~10/11. Peak gains might have been 15/16, but they were along other portions of the powerband.

Huge difference. :D I really love it.

Dinan had the same feeling at WOT, but a light cruising it doesn't have the OOMPH. But it was easier on the MPG. Different strokes for different folks.

Who said they ran there car on regular....Such disrespect and bad to your engine

i've got a Bav Auto chip in my ETA & love it.... i'm still waiting to do a direct comparison on a JC chip.... Beirbrennere30 has a JC chip in his eta & whenever we get the chance we're gonna swap ECU's & do some independant testing 8)

I wasn't too impressed with my bavauto 325i chip, but it definetly increased the grunt and pull after 3500rpm, and the extra bit of rev limit is nice. plus I got it used so it was cheap, and they don't have a JC chip listed for the 526ecu

The accurate gain can be described as 'negligible'
