JB4 iso issues

emackin · 03-19-2013, 06:47 PM

Last weekend I updated my JB4 to iso and when i was testing on map 5 i saw my boost spike to 20 (which it never did before the iso update) and my ses light blinked then went away. Since then i have done some more pulls on map 5 and have not seen this again. I tried checking codes but none showed up (i did have auto clear codes on though). Heres what my settings were
boost failsafe: 17
default wastegate: 80
PID:25
autoshift damper: 60

If you're worried, grab some logs and shoot them over to Terry. SES light blinking 4 times usually means running lean, but that triggers a switch to map 4 till you turn the car off then back on again so you would have noticed targeting around 7-11psi. But any concerns just email Terry, his customer service is phenomenal.

I don't know why, but I've seen a few problems with the ISO update on the N55...
Many people are good with it though.

Usually problems with e85 too..

I, personally, am worried too much to go through with the update.

I was worried it too it was the first time I updated the jb4 but everything seems fine now little different idling but I did get the ses blink 4 times and its ironic you say running lean I had a tech in my car at the time with a degree in fuel mapping and he said at that moment smells lean so I hope that's it
