yoda598 Posted October 2, 2022 Share Posted October 2, 2022 Hey guys, I have a single cam au on the dyno currently with a bf ecu running the show. Currently having issues with cylinder cut stepping in for no apparent reason. I'll post the tune and a data log shortly. Bit of information. Running the car in open loop as it's a drift car and doesn't need fuel economy haha. Have had a search but have no definitive answer.

Roland@pcmtec Posted October 2, 2022 Share Posted October 2, 2022 What is the torque, fuel and spark source showing in the data log? If you do a DTC read with Forscan what codes do you have? What does the rpm signal look like if you log rpm and nothing else? Could it be a crank trigger issue? Quote Link to comment Share on other sites More sharing options...
yoda598 Posted October 12, 2022 Author Share Posted October 12, 2022 i completely forgot to post the file. DTCs are plentiful as its a conversion car. RPM signal is steady and perfect. all torque requestors are driver demand as far as i remember. attached is the file as the car arrived HACCKD5 MCsporan drift ute as found.tec 03-10-2022 02-09-41 PM Log cylinder cut.teclog Quote Link to comment Share on other sites More sharing options...
