2013 ZL1 - E85 IAT2 and IAT Advance
2013 ZL1 with mods listed below. On E85, HP Tuners is showing IAT2s of up to 174 and -4.4 IAT Advance at WOT, but no KRs. Is this normal? If I switch back and forth from 91 octane to E84, will the IAT tables automatically adjust, or do I need to make some adjustments in the tune to lower the IAT2s even though I have no KRs?
Lingenfelter GT14 Cam, West Coast Stage 2 CNC Ported Heads, Dynatech Headers, RotoFab cold air intake, upper & lower Lingenfelter pulleys, Fore Innovations L4 Fuel System, Phastek DSX Flex Fuel Kit for E85, ID 1150's, reinforced intercooler - last pull showed 694 rwhp on the Dynojet |

Just depends on your tune, while you might have a -4 timing pull with those IATs , what is important is your total spark advance.
If your tune is setup right and you have a ethanol sensor you dont need to change tunes all the time I do not believe the IAT tables change based on the E content of your fuel. |

The type of fuel has nothing to do with your IAT advance table. 174 is cooking. You need cooling mods bigtime.............

ABADZL1 is right. 174 is way too hot. Get that thing cooled down.

When I road race, the highest I've seen on a really hot day in a 20-25 minute session is 165° - before I added meth (I'm not running it harder than 7/10 ;o) .
Gotta cool that thing.. Running E also. Only good for keeping cylinder temps down and of course power... -Don I have a lot of cooling going on ;o)

S/C cooling mods should be done first in my opinion..
