Bad Ign Timing? / Reading Logs / Log Help

Can you connect the jb4 and give me a screenshot of your user adjustment settings? Scroll down for bits 0-7 and lemme see what’s your current setting first.

Here’s everything. I haven’t touched anything myself but I did buy it used. Haven’t run the map yet either

Try 118 for fuel bias for all rpms and turn on bit 1 and give it a pull to see how it looks. Better be a long WOT pull that auto shifts once or twice. Usually people are fine with bit 1 but let’s make sure it runs happy first before you have fun with map6.

keep the boost on 0? or do I put it to what map 5 has and put it to 7 psi across the board

That setting applies to all maps. So no need to play with map6 numbers for now. Your boost tapering at high rpm is not even that bad. Map5 should be enough for you to have fun with for now.

oh okay, i didnt know that, ill put those settings in and give it a run sometime today and post the logs once I do. i really appreciate the help btw, how do you know so much?

I was having full tune at first then JB4 stack on that full tune. JB4+ back end flash now. Totally backward lol.

here you are my good sir. So one of my brake pads without my knowledge came dislodged and rubbed on my rotor the entire night which was great, but anyways, here are two logs.

Did a lot, a lot, of pulls tonight on a closed course and it felt great, no rattling or knocking sounds or similar. All very good. Map 5.4 log is a little confusing since I went and then stopped and went again. But should be plenty of WOT. I believe I was in manual mode for 5.3 log and I’m 100% sure i was in automatic for 5.4. Everything looks good to me besides ignition timing but let me know your thoughts. Thanks again for all the help

Looks all good to me. No need to mix any more E or run more boost at this point. Fuel trim is about there.

that surprises me a lot. could i run more E if I wanted to? its cheaper...

You’ll need the help of CPI and a back end flash to make you run E60 ish. You can actually try 119 and 120 for fuel bias. You would like to see AFR fall at 12-11.8 in the end of a gear and you are below that for now with 118

we have a new problem. feels like the car goes into limp mode when in map 4 and 5 (more common in 5 but happens in 4) - it doesn't happen in 3. I don't think its limp mode though. I'm not overboosting, I've checked logs.

First I thought it was because my octane wasn't high enough, So I added some extra E. then it kept doing it, so I thought I added too much and put fuel bias up to 119, albeit it may have felt a little smoother, it kept doing it. no idea what's going on, as map 3 works perfectly fine as every other map does.

in some cases it completely removes boost until I stop and start the car again, other times I switch to a lower map and the boost is all there.

upon checking logs, it shows the gear switches and the pedal goes to zero - but my foot doesn't come off the pedal. even though it says zero, my foot is still most definitely on the pedal in that moment. its like the ecu is saying 'no more' but nothing appears to be wrong? i only got one map of it and its short but it shows everything important i'd think.

To much E. Fuel crashing.

Would a higher fuel bias fix that?

Nope. You need to run less E.

I’ll try putting some more 93 in the tank soon - how do you know it’s too much E? Asking for future reference

Your FP_H is below 10 which means there’s a fuel cut. Also your trims are maxed out. 25 on the log is 0% fuel trim so you wouldn’t want it to be higher than 50 after WOT.
