What tables should be modified to compensate for heat soaked sheet metal intake in both LS1B and E38 for Fi or N/A cars

Thanks

What kind of IATs are you seeing? Or wouldn't you want to monitor closer to or in intake IAT?

At idle it could go to 170F
I want to know what tables need to change for fueling in this case
no problem with spark tables

LS1B: B4901,2 model the ECT/IAT balance.

so i should make it work tward ECT ?

so i should make it work tward ECT ?You have to guesstimate how much heat is transferred to incoming air...

if intake is getting hot, sure move the balance toward ECT... when you have it right, things like VE and trims fall into place.
