I've just started digging into the 411 PCM, but so far I'm pretty impressed.

My idle is messy but I am also running stage 2 cams and pretty serious porting so not sure if it because of the pulse width or low velocity at low rpms. It comes on so strong about 6k that it pulls through the clutch.

GM learned a lot from the development work done by Lotus and followup stuff with the racing effort. If you are going to compete at that level you need the best.

Fastlane went to single injectors and a Motec in 93-94 and he probably knew more about what works than we realized at the time. Every time I talked to him I learned something. He told John L what he wanted/was doing and John woluld try it and find he was ahead of everyone. To bad he left the hobby. You want turbo code for the LT 5 just borrow the ecm/code from the Cerve III. Geoff said they tested that for a lot of hours on the dynos at Lotus before releasing it for that car. (He did have that code, not sure he still has it though.)
