I had checked on 6.0T before I answered. I doubt it changed since it's been that way for many 6.0x releases. Since the parameters for all JetCat engines are stored in the ECU, a software update may or may not affect your particular type engine.

I am not talking about holding buttonsduring turn on. AFTER its on, push and hold Limitswhile pressingthe Right Arrow button. That puts you at Uaccel1. Releasethe buttonsandthen pushthe Right Arrow to scroll to Uaccel2.

Uaccel1 only affects the pump start up voltage right after the propane lights off. Often enough it can be used to get a quicker transition to kero and faster initial rpm surge. Too much and you may get flames. Uaccel2 is the open loop pump voltage right at propane turnoff and allows you to fix a pause or sag in rpm acceleration at arround 18k-20k rpm. I've changed Uaccel2 quite often to make for smoother starting engines.

You can still still look around on the GSU even if you're happy at this point with what you have.</p>
