MattSkylineGTT Posted May 31, 2022 Report Share Posted May 31, 2022 Hello! I have a 99 Skyline R34 GTT - running a Link G4+ Storm ECU I have been having a really annoying Missfire - a real lumpy one. Totally random as to when it happens but it can last over 5 minutes. I have attached my Log file, just wondering if anybody could take a look and see if there is anything obvious - the missfire settled itself around 20 seconds before i turned off logging. Cheers :) missfire 31may.llg Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 31, 2022 Report Share Posted May 31, 2022 Do you have a wideband hooked up to the ECU? Do you have a copy of your tune handy? Quote Link to comment Share on other sites More sharing options...
MattSkylineGTT Posted June 1, 2022 Author Report Share Posted June 1, 2022 I don't think I have a wideband (not sure how to check), I'll fire her up to download the tune data though Quote Link to comment Share on other sites More sharing options...
