Log from 03-04 shows a nice and clean run. No timing corrections or anything else. This is also with the MHD flex fuel CAN kit installed. Second run from today, 03-05, shows a sudden timing correction on cylinder 5 following up shift to 4th gear. One thing to note is if you look slowly over the timeline, you will see boost pressures jump to 28-32psi for a fraction of a second. I doubt this is going to cause any issues. I’m sure that’s the case in a lot of vehicles, even completely stock. Logs were both run on the 93 Oct map, with approximately 32% ethanol mix. Stage 1 map only. No downpipe yet. Just a large, short ram intake. Nothing else as far as engine mods are concerned. Looking for feedback on the second log with that sudden timing correction. I’d typically write little corrections off but you can see it follows in a linear fashion with the cylinder timing. And all the others are fine. Don’t get it. Was I perhaps getting ghost knock in that cylinder? Car ran strong and didn’t hear, see or feel anything out of the norm.
