Seems like you are not the only one.

Looks like the car is trying to save itself. You are lean with AFR, DME is pulling back boost, timing has multiple drops, etc. Get a log on map 1 and let's review. Also, update to the latest firmware V14 before you relog.

Do you have EWG and/or Fuel harnesses? Personally I've never seen a stock car on pump gas run map 3 well. The stock fuel system usually hits it's max in that scenario.

Really ? Makes sense for me, because it happened while takin off from a light, but roads were quite snowy and slippery, I was part throttle in gear 1-2-3, no hard accelleration....just casual driving.

However I spent a lot of time getting sideways anytime I can, and it only happened once...

Use 14.hex and do not turn FUD6 on since you are not using the BEF. That uses same mapping structure you're used to, but offers more accurate logging parameters to view.

Generally easily resolved. We've disabled that fault in the BEF maps (just posted latest files with fault disabled, make sure you have latest MHD app to update), and if you are on the stock flash then you just need to limit boost in 1st gear to avoid triggering it.

I have the BEF and still limit boost in 1st and 2nd. Currently set at 6 and 4 respectively. Otherwise the car is out of control. It's still slippery at those levels, but easily managed. I'm not a drifting guy... it's all about speed for me.
