OK, I Finally had a chance to take Benzer 1 to the track this past week-end and with NO OTHER CHANGES from the previous time I had Benzer 1 at the track, except for the substitution of the ECU bearing part number 002 545 97 32 and the removal of the resonator and muffler, Benser 1 went a full second quicker in the quarter mile in much worse conditions than what we had the last time we were there! We are talking an uncorrected 15.95 @ 87.27 (15.487 @ 89.939 MPH corrected) where last time we couldn't do better than a 16.95! Mind boggling! We repeatedly spanked a Bimmer 525i in the process too! (Well, actually, slaughtered the Bimmer.) I honestly think that I was more thrilled to get that 15.95 out of Benzer 1 than I was when I got that 14.348 out of Benzer 3!

So now we have some "real world" numbers to back up all of the theories we have discussed here in this thread. It turns out I was on the right track, I just needed to finish the job by freeing up the exhaust and trying that older, Non-California ECU! Sometimes we are just looking in the wrong places! We have to take care of the basics first. Now this car might be more responsive to some of the other tricks discussed here in this thread!
Regards, Eric
