87 s10 2.8 with e85

I got the data from the original chip. I had the voltage set too high..

"Async pulse coming out of DFCO" Is this extra fuel injected when the fuel cut is coming back to fuel at low rpm? Having stall problems while decelerating and pushing the clutch, engine will stall. I have set the Async pulse to 15ms but it doesnt help, more?

that is the correct usage of that item. it's possible you need less fuel, 15mS is a rather large burst of fuel, especially at low load, might be enough to not fire reliably.

then again, with E85..... you might need significantly more than what an engine running gasoline would need.

[sbc350]

Yeah it needed more, 28ms did the trick!

edit: I figured it needed more since the start point was zero..

I'm using redline e85 additive to keep the injectors and fuel pump alive, been good for 10k miles now. Drove the whole last winter too, I use electric engine heater at home and work so the engine is about +20c when starting and it starts fine. Haven't noticed any ethanol in oil neither. I also modded the warm air valve to keep it sucking warm air from the top of the exhaust manifold to the air cleaner all times expect full throttle. The engine warms up to the point when thermostat opens just like with gasoline, maybe a lil bit slower tho. The stock old fuel tank started to leak under the band which keeps it in place. Planning to buy a new one or weld one out of stainless steel. Gonna replace all the hoses and filters too before they give up :)

I have to keep the stock engine because of the regulations, or at least I have to mask the bigger engine with the tbi intake to look like the stock 2.8 :)

Does anyone know where I can find the BPC setting in the 4e?
edit:

Found the minimum BPW, minimum Async BPW and maximum Async BPW, how does these settings work?
Trying to figure out how to modify the stock tune for bigger injectors to run gasoline..
