Title: 95 e34 M52 obdi s52 cams
Post by: heinera on November 14, 2013, 11:55:13 AM

Hi,
my 95 525i M50 engine was getting tired with 250K+ miles, so i bought a wrecked 328 for the motor. I recently installed it along with m3 cams, the pink injectors, the M50 valve cover and coils, underdrive pulleys, 255lph fuel pump, a lightened flywheel and stage 2 clutch.

When I finally got it started with the stock tune, its not right. It has sluggish throttle response, and needs the throttle feathered to run. I figured it needs a new tune. I found the War Chip forums and saw someone has uploaded just the tune i need. So when my new War Chip arrives in a few days I will give it a try. I'll update as it happens. ;)

with the 255 you will need to remove some fuel. It will drive up the base pressure slightly and all the NA tunes are made for the stock fuel pump unless otherwise stated. Just a heads up since most people don't realize upgraded fuel pumps do in fact change the tune.
