ECMlink 1G SD E85 RICH

[bryanzomg]

I just put together a buddys car, trying to drive it to tuner without it blowing out the wideband sensor from being too rich. Runs really rich between shifts it backfires bad and killed sensor.
Mods are as followed, E85 FUEL 16g turbo, PTE 1000cc , wired 255 walbro (stock fpr) br7es, .020 gap, Gm 3.3 map sensor, DEJON SMIC.

You need to check the box that says "disable MAF compensation w/SD operation"

You must be logged in to view this image or video.

And global fuel should be closer to -33%.

I didn't go through the rest of the tune. Start there and see how it goes.

+1 what Brad said. It's lean, not rich. Zero out the maf slider. ISCposition is way off too.

The global was calculated using 9.7:1 stoich since I was running e85

You still want your wideband to read 14.7 when idling with e85. And somewhere around 12.0:1 during wot.

9.7 parts air mixed with 1 part e85 fuel will read 14.7 on the wideband.
