Been working on a bone stock RR, when I go WOT (not every time) the buggy completely shuts down. I get 3 beeps, a "Limp Home" on the dash and by the time I pull over the dash is blank and not running. I put it in P and it starts right up and drives fine until I go WOT again. When I read DCTs I get P2279 Intake Air System Leak.
So today I preformed a Boost leak check by applying 20lbs of air through the cold side of the Turbo and spraying soap water to Intake Manifold(advised by Can AM dealer I could have a hairline crack in the intake manifold) and all hoses and connection's as well as the intercooler and no Suds anywhere that I can see.
My logs show that I am making 16-18lbs of Boost, my fuel is .80 Lambda and No Knock on stock spark and boost tables.
One log shows 19.33lbs of boost which did not hit Limp Mode
My Injector Duty Cycle shows less than 85%
One day I can make WOT runs and no Limp Mode, the next day on the same .hpt file it hits Limp Mode every time. ?????
I suspect its a Wastegate issue.
Buggy runs fine at part throttle and Idles fine.
Any suggestions???
I am using The Tuning School Can AM manual
