Title: Bosch ME7.9.9 XDF OR DAMOS Post by: Antunesmano.rs on November 05, 2024, 04:56:31 PM Hello everyone, I've been working on tuning my Chevrolet Vectra Flexpower N20XF 2.0 (I'm Brazilian). It has a Bosch ME7.9.9, and I paid someone to make a few adjustments to the file, but I wasn't quite satisfied with the results. So, I've been putting in the effort to learn more and more about this ECU. I ran some tests using a scanner, and the spark timing between 3500rpm and 6200rpm consistently stays between 29~27. Starting at 4000rpm, the MAP sensor drops from 910 to 940, and in the 2000 to 2600rpm range, the timing advance is reduced by 3 degrees. I need to adjust my calibration but am a beginner, and I'm looking for knowledge :D
I see that you use TunerPro a lot; I’m trying to learn with WinOLS. The ECU was read using a KTAG; here are the files for comparison. Title: Re: Bosch ME7.9.9 XDF OR DAMOS Post by: Antunesmano.rs on November 05, 2024, 04:58:54 PM CORRECTION THE MAP DROPS FROM 910 TO 840
