Hot start fix for the EVOX's.
I have DW1000's and always have a hot start issue. I've tried putting this table at all zeros to no avail.
I will try your numbers, but I doubt it will help me much. Once my car DOES start, it's obvious it was too rich in the chambers as I get a good plume of black smoke for a second.

The formula to figure out how much you need to change... this is for regular fuel (93/91)
New Cranking primer IPW = old IPW x [ old injector scale / new injector scale]
for E85...
Although I am not 100% sure...
Is figure out the forumla same as above, since most likely you tuned latency and scaling on regular fuel then switched to E85. Then once those values are figured out... multiple the entire table by 0.3-0.35 or 35-35%. To have new numbers...

The 10's seem to start up a bit better about starting up in colder temps with E85 then the Evo8/9 but they still require more IPW adder.

I definitely had warm start issues on ID2000's (E85). I was frustrated and just went back to DW1000's, which work perfectly for me. I'll have to give my tuner another shot at this table.
tephra, was it an actual email or PM? I didn't get one from you, please give it another shot:

I plan to actually try lowering the adder for my FIC 1100 on e85 in the 70-100* area... it doesn't take a really long time to start, but an extra crank or two from what I remember on pump when the car sits over night.
I'm pretty sure you would want to multiply by 1.33... e85 generally requires more fuel not less. (and this value does not work on "inverted" logic like injector scaling). In any case, for the injector scaling you want to subtract 30% or multiply by .7 .

basically it comes down to trial and error.
in the end, if your having cranking difficulties, this table is the one to look at (after you have ensured your trims are within +/- 5%

CRAP! tephra I still didn't get it. Is this something you can send me in a PM here? If not will you try sending it to jarrod@buschurracing.com he can give it to me. He uses firefox or something and has less problems.
Sorry.
Sorry.
