Base Low Coolant Timing Map

Base Low Coolant Timing Map
Has anyone messed around with these maps for running E85? If so, what have you found that works well? Has this map made a huge difference in your cold starts or none at all? Just curious to see how people are approaching these maps. The same goes for the IPW adder map.

IPW adder I have increased IPW at lower coolant temps and it has helped cold start on E85. This is exactly the same thing thing the E85 "cold start helper" kits do.

Razor, you have numerically increased the ms from -8 to 20 or have you done something different? I have my baseline coolant trim map set pretty close to my high oct ign map and I didn't notice a difference between the "original" map or the one I put in.

I put 0% everywhere. Car became butter smooth to drive when cold. Who needs to light up a cat when they have none I don't think there's any other reason to have the timing retard.
I increased the IPW adder values for hotter temps, my 1000 injectors want a blip of gas when i start the car hot. It's a non-issue for me really, but maybe this table will improve this. I played with it a bit but as they say results are inconclusive for now

The car fires right up on first crank and goes to about 1.6k(normal) and then it drops to about 500rpm- almost stalling, and then shoots back up to normal. It does this about 3 times or for the first 30 sec of start up. Any ideas what I need to do to keep it at 1.6k and stop the stall drop?

I see. Any direction on which way to go on cold start? Awesome info once again. Thank you. Is the IPW function just a band aid for wrong latency values or does it really help once the correct values are dialed in?

The IPW map helps cranking start.
Everything works better usually when the injectors are dialed in well.
Thing about the tuning the cold cranking on E85 is you really only get one shot at it a day.

Tell me about it- so annoying. If front o2 is all over the place what should I do with the latency at 14v- raise or lower? From -8 to 20 I have 49,27,20. Is that close to what you have? Sorry for the obcious questions but the wideband is in the mail. I have .624 for 1000 fic's at 14v.
