You'll need to re-tune VVE and MAF.

Hadn't even thought about doing it for that reason. That's a good idea, especially with how ethanol acts cold.

so here is what i ended up with after applying the injector info from your cal. then tweaking on the VVE. new vve.hptGHuggins.hpt
how important is the short pulse adder? looks like i didnt copy that one over, but i guess i could throw it in there and find out.
Short pulse adder is injector specific - no need to copy over.
MAF and VVE both look really nice, smooth, linear and realistic. Up to you on which timing tables you want to run. Guess it just depends on the ones that perform the best over all.

I shouldn't have the problem of sending fuel out the exhaust with a stock cam (for now), but I did notice a cold hesitation since I started running E85 this past year. I'm not sure that it wasn't there on 93 as I am not in the habit of rapping the throttle until fully warmed up, but maybe it was, or maybe just not as bad/noticeable. Too bad there is not a 2nd inj boundary chart for flex fuel. Thank you, I may have to play around with that the ECT chart a bit.
with ethanol i like to be different in some ways, what i do is for cranking fuel only about double the amount in the cold cranking range or increase it till it fires easy with eoit at or after EVC as u would when at operating temp, then once running the OL lean it out to the .95-1.0 commanded or even if its commanding richer make sure the WB reads the .95 - 1.0 lambda once its running that will also help it warm up, dont just go super rich when cold it will be wasted and take longer to warm up, the cranking spark usually with camshaft i have it bout the 0-5 deg adv just so the piston is closest to most compression to help when cold, i also add to the dwell time for the cranking rpm to get a better spark, all this seems to work for mine on ethanol it may only crank over a second or two longer then fire up, hot starts should be almost instant
