trutorque Posted February 18, 2019 Share Posted February 18, 2019 I've had 2 cars now after doing the ghost cams and returning to stock for a long trip. Then ive tried to load the cammed file again if found it will not cam like it originally did and run like crap and stall.no alterations had been made to the files since . I've even tried starting from scratch but no luck. What am I missing . Cheers Quote Link to comment Share on other sites More sharing options...
fordsrule Posted February 18, 2019 Share Posted February 18, 2019 That's weird, i'll be interested in the answer for this one Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 18, 2019 Share Posted February 18, 2019 Maybe fouled plugs? I would check the long term airflow and fuel trims before and after also. The computer might be getting confused with the false lean idle and making it run excessively rich. Try turning off long term fuel trims and see what happens as an experiment. 1 Quote Link to comment Share on other sites More sharing options...
trutorque Posted February 18, 2019 Author Share Posted February 18, 2019 Cheers Roland. I'll give it a go. I've also had a car from another shop do the same thing. So I'm keen to get it sorted 1 Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 18, 2019 Share Posted February 18, 2019 Personally I'd run it open loop if you want to get the idle better. Otherwise the overlap will induce a false lean reading which will eventually peg the LTFT at +25 and spit fuel out the pipe. Make sure you retune the overlap SD adder tables at high overlap as well to help the PCM have a better starting point. 1 Quote Link to comment Share on other sites More sharing options...
