would the iat/ect comp parameters help if i had them set so they dont reduce the fuel(e85) as much at higher temps? theory being that its running too lean at 4k rpm with only 14-20% throttle, and thus raising combustion chamber temp.

that means the fan doesnt come on till 190* right? why wait till that high before letting fan come on? what temp does it come on stock?

already have it at 180* and 80mph.

i know its supposed to, but taking it out has been the only thing to help AT ALL. before removing the tstat, the rad fan NEVER shut off. at least now it shuts off at idle and around town. could the iat sensor location be causing ecu to do something that isnt beneficial at cruising speeds? or pcv ...

no one can find a physical issue causing this yet. could the ign timing being too advanced at the speed, rpm, ect,and iat cause this? or fuel comps at same settings?

thank u. i will try to make some sort of scoop or something to increase airflow to rad more.

sorry. within 10 mins of cruising it hits 210 and still rising till i turn on heater or slow down. seems related more to rpms (4k)and throttle% (11-18%)

on hot days(80+) the ect is over 200F when crusing on highway. 65 mph and over. rpms at 3.7k+. partial throttle. replaced rad with mishimoto full setup(rad, fan, and shroud). even blocked off the ac side to improve airflow to rad. fan never turned off until i gutted the tstat. it does actually turn ...
