Default Was driving, doing some pulls and got complete loss of boost. - 02-25-2021, 07:04 PM

As the title says, was driving and doing some pulls. Suddenly i had zero boost, couldnt build boost at all. I looked at the log but couldnt really tell what the cause was. I assumed my wategate was stuck open so i couldnt build boost at all, i did have the "lagfix" setting set to 80 which i have now reset to zero. Left the car off for 30 mins and drove it again, no issues.

If someone could check the log that would be great. i think the issue starts around 1536 timestamp.


EDIT: i have attached a new log as i did some pulls after work and it seems fine to me now but if someone could check that would be great.

This reply won't help... but I can't see anything. 90% of the time it's over boost, too much E, or HPFP crashes, none seem to apply here. The only thing I can add is on your 2nd, 3rd,4th and 5th pull, plug 5 looks bad, huge timing variation. Terry might have to chime in

I'm sure the plug came from BMS fine. Double check gap, is it torqued properly, did you crack it accidentally going in, is the coil pack pushed down all the way? Again this is probably not why the car went into limp though but Terry would know better.

i posted a new log on my original post, car seems to be running fine now. Did some hard pulls tonight and no issues, no timing variation at all. Might of been a spot of bad fuel? i dont know but its running fine now.

Just curious, what year is you Stinger GT is it AWD? I have a 2021 and I’ve been having the same issues since I added the catback exhaust.
It is worse when using paddle shifters.
Injen intakes it never happened.
I put new HKS plugs in prepping for JB4, but I’m getting the sense that this car is super protected or something. Perhaps the 2021’s have stricter regulations, I’m lost: hopefully the JB4 will allow it to not go in limp mode all the time.
Frustrating

I have a 19. I will tell you I've limped my car a dozen times, it's part of the tuning game. It's a good thing because if it didn't, things would break. Anytime you bolt something new on, the computer has to learn, rebuild adaptives and new tables. It's not uncommon.

Set the lagfix back to 0.

I get the same issue and it is because of the lagfix. It will do it like 1 out of 5 pulls randomly. Terry is working on a fix right now.

Set it back to 0 and go do another log. Also, set your logging to 90% throttle/3 seconds. that way you don't get log sheets with a ton of useless data. When you log make sure you do all of 3rd gear or 4th gear. Both gears up to 100 mph at 100 throttle is best.

EWG connectors installed? If so FF appears to be set too high. The default is 50.
