Default Fuel limitation based on Transmission?? - 05-23-2020, 03:55 AM

Mission Performance has come out with a transmission flash and claims to have made an interesting discover. They state that the transmission is sending information back to the ECU which is causing it to lower fuel pressure as a way to reign in high torque values.omegle discord xender Wonder if this means that a trans flash + jb4 could overcome a lot of the issues we are seeing and attempting to solve via meth etc.

It hasn't been my experience on the tuning end. The trans will send a low torque request in to the ECU if you set the calculated torque too high in the flash map accidentally. But the ECU lowers it's boost target not fuel pressure to compensate.
