You must remember, we are using approx. .550 inch lift cams with GT3 pointers on these billets. This system will handle this too.

However, despite what you may have been told, PMS is totally uncontrollable. I'm sure you meant "PSM".

I just watched the newest Fast and the Furious and reading this thread made me feel like it should've been part of the script.

I promise to release all information very soon. It will be on the engine dyno in about 30 days. Then into the chassis. At that time I will report the good, the bad and the ugly.

Somethingthing like this http://www.bayareamotorsport.com/alphan.html The basic principle I mean. To control ABS & PSM you need slightly advanced thechnology than the one meant for e30 Beemers...

PS. Inspiring project you have going on here.

Believe it or not, ME7 does very well with no MAF.

Ask JohnD, we ran his car like this at one point very early in his tuning with us.

It is the "BMW" RSR ABS. Bosch also makes a good one, however from the information I received ............. not as good. The BMW system stops far quicker with no "pump back" at the top of the pedal when hard braking.

Yes, it reads the pressure density. No MAF needed.

I corrected your above site so it can be accessed. I have read it and what we just ran across is different. The information for what we ran across came from one of our people involved with F1 racing.
