Cobb + JB4 logs map 6 additive Virtual dyno

I run today couple of pulls to test the new flash version of map 6. Basically you can add boost/additive per RPM when meth is flowing.
Base map STage 2+ FMIC.
This is a log a Virtual dyno with 5 + psi at 7000 rpm, 4 psi 6500 rpm, 3 psi 6000 etc.
Dual nozzle 1050 ml/min meth. quite cold out 27C , lots of traction problems.

There is also a new function in Vdyno that allows now to do and check graphs, pretty cool . overall i am happy with the combo and can push even more boost if needed.
Fuel pressure set to 50 , need probably to increase it a bit.

Hmm... Good info but your AFR doesn't appear happy. I know when I was testing my Cobb + JB combo a 90FPadd caused insanely negative trims, 40 seems to have fixed it. Try the 90FPadd see if it helps.

Are you running a 15 ohm board?

Look like a WOT onset throttle closure. Happens when the dme perceives an overboost condition.

yeah its the 15ohm board. My trims are negative though. I am pretty sure there is some adaptation there to be done. Also its very cold and slippery.
Nice though it works perfectly fine. More testing later on.

You're not really running that aggressively in terms of boost or timing so perhaps that's why your trims are going so negative with the fuel pressure bump. I understand though, traction is a problem for most of us right now!
