Hi Adam, I have found the problem with the running on 4, it turned out that the coil wiring for 5 and 6 was wrong but I will check some of the other things you noted now I can run the engine for longer, I didn’t have the vacuum line on the fuel pressure regulator at the time I took the log, iv got a load more things to check now it runs on 6 lol it is a Syltech map sensor

I have tuned the antilag etc off and tried it but still the same, i have tried to capture a log as well, not sure how good it is because i cant leave the engine running to long with the missfire as bad as it is and how rich it is lol Log 2024-04-26 9;25;47 am.llg

Sorry it was a last minute idea to ask on here before i went to work, i will try and get a log of it running tomorrow because its a bit late to start the car now lol, ill attach a copy of the rough start up map. G4+ Thunder R32 GTR Engine Kill Off.pclr

Has anyone ever had an issue or know if there is anything in the ecu setting that would cause the engine to run on 4 cylinder (1,2,3,4 working 5,6 not)? It’s setup as a 6 cylinder and the firing order is correct, If I do an injector test and coil test through the ecu they all operate correctly, if I test the injectors with a noid light they are working when cranking, tried a plug in each coil out of the engine and they are all sparking and iv even do a compression test on the cylinders (fresh engine build)
