Hey guys I am throwing a P0717 and the p0300 misfire after installing a built 4l60e with 2800 stall. Truck is a 4.8 lysholm supercharged 3:73 gears
I did a few runs and when i first start out the iss and turbine speed does not log until i am around 22 mph then it picks up and reads. it throws the code and i clear it while driving an the iss reads like normal and tcc lockup will engage. it will eventually set the code again and unlock the tcc but clearing code will reengage it instantly. my iss seems to never drop out while driving after the initial take off i can stop and go and it reads fine. Is this a stall converter tuning issue? I did most of the recommended tuning for the 4l60e but still get this code.
Under heavy throttle it throws the p0300 misfire and I have maxed revoltion table out. Not sure what to do on the other tables.
I'll post the tune but be gentle this is my first experience tuning so it may be a wreck.
Still trying to figure out logs and such so I dont have one to share
