Log review - Lag when data logging/mashing accellerator pedal MHD 2+ E20

///M248 · 07-06-2019, 11:35 AM

Appreciate anyone who can chime in here.

I've noticed a lag when datalogging in manual mode. I hold the rpm around 2500 then punch it, and there's like a 1 second lag. Looking at my logs its clear the DME is pulling the load target back midway through the throttle opening when I'm mashing the pedal. There's a clear spike and dip in in rpm as a result.

The only thing I can notice is the rich AFR vs target, then the dip. Do I just need more E85? I was running a calculated E25 mix.

When browsing from a mobile device it doesn't show the signature, which is the reason I asked

But feel free to chime in since you see the mods in his signature
