Re: No Performance Chip for 1986CSi? HP boost adv (archive)

: They sell the popular Jim Conforti chip which is definitely available for your car (as your car uses the same engine as the 535i). I have no personal experience with Turner Motorsports nor do I have experience with the Conforti chip, but I have read mostly favorable reviews. I think the posted gains are +24HP and +30lb/ft Torque.

: Keep in mind that your car is old and the electronics are fragile. Changing the chip might damage your DME as I have read several horror stories on the E28 board.

I've put a Jim C. chip in my '88 635CSi automatic, and have noticed a definite difference in the power band above 2000 rpm, really noticable above 4000 rpm. Great for passing on the highway; however, doesn't turn the car into a drag racer (significantly better 0-60), if that is what you are expecting. I spoke with Jim personally before getting the chip, as I was concerned about putting it into an older car, with (at that time) 98,000 miles on it. In short, he assured me that the chip would not adversely impact the car, and the last six months of spirited driving have so far proved him right.
