Subject: <E28> M30 Conforti Trip

I'd have to agree with Chris Guy's review of the Jiom Conforti performance chip for the M30 motor. I installed the new chip in my '87 535is about 2 weeks ago.

As Chris noted...there is noticable difference was a rock steady cold idle..... previously the cold idle would surge repeatedly for the first 1-2 minutes of operation.

Performance is vastly improved in mid-range throttle response. The car used to accelerate in what seemed to be step intervals....where the car would seem to plateau momentarily and then resume full power acceleration. With the new chip the acceleration is consistently strong, smooth and linear from 2500 - 6000 rpm.

Top end-performance is similarly improved....the steppped acceleration that I mentioned previously used to flatten and stay flat after about 5200-5500. Now the car still pulls strong at 6200.

To me, this is exactly how the car should have been engineered to perform from the factory. I'll be curious to see if there are any differences in my exhaust emissions when I go for state vehicle insprection in March.
