BTW, for what its worth - my friend who works with the MegaSquirt crew said one of the newer MS setups could handle the tuning just fine for the 370. So, in reality, there IS a tuning solution out there - someone just has to use it.

Crash - the VVEL system changes the lift on the intake valves alone, so, in reality, you can tune the VVEL system as if you were tuning a normal drive-by-wire throttle body. As someone said in an old post, the TB's on the 370 are open 100% during all normal operating conditions, and the VVEL system acts as the throttle body. So why are we over-analyzing this? Just think of the VVEL system as the throttle body itself, and we all know the tuning is directly tied to how far the TB is opened, along with the current amount of air flowing (assuming you're doing a MAF tune and not speed density...).

Cliffs: theres no reason anyone cant use a MegaSquirt tuning solution RIGHT NOW to tune their 370.
