I noticed on my mirage The anti lag launch control started acting up. It used to hold the rpm to 4500 and build around 10 lbs of boost. But then it started reving past 4500 like there was no rev limiter. Then the other day it started cutting out under boost and the check engine light would come on. It felt like fuel cut But I know it wasn't because I'm running a 2 g mas and dsm link. Ok now to the worst part. I went to fill it up with e85 yesterday and it ran fine except above 10 psi so I was just cruising. I filled up and was leaving the gas station and it just died. I pushed it around the corner and tried a couple more times and it fired up and I made it home. I go out to start it today and It cranks and cranks but doesn't fire up. I hooked my cable and laptop up to try and figure it out and ecmlink wont connect any more. I put the old known good ecu in and it still wouldn't start. All my fuses are good and the check engine light dosnt come on when you turn the key on any more. This tells me the ecu isnt seeing power any more. What should I check first? Thanks in advance for the help Guys
