Email me if you need a hookup on the pricing of the ECU/TCU. My intercooler pump crapped out and the engine was dialing back timing to resist detonation, shes running perfectly now.

To my understanding, professional racing uses a different system. The ambers on the tree light up simultaneously with the reaction timer kicking off on the last amber light. I forgot, but a .4 or a .5 second reaction time is perfect as that is the time elapsed between the last amber and the green light.
Correct me if I'm wrong.

You are correct about professional drag racing using a different system as they always use a .400 "pro" tree vs a .500 "sportsman" tree for guys like us. But no matter what tree they use the clocks never start until the light beam is broken and the car actually moves.

these are the tires i run...been trying to tell people about them on the e55 board but everybody swears by the ps2's. i guess it's better that people don't know about them...when they pull up next to me at the stop light with the ps2's, i'll leave them in the dust!! re01r...best tire period!
