Hi Greg, with the TPS disconnected you are only using the 100% WOT map, this is not detrimental to your engine as many guys with Mik 42's are running without a TPS. But it does mean you are using WOT ignition advance for all throttle openings.



Isn't it the purpose of load-based advance to optimize efficiency under steady-state, partial-throttle conditions? If disconnecting TPS disables this, I would expect it to adversely affect fuel mileage, especially when cruising. Has anyone here with TPS disabled compared before/after mileage?
