i'm guessing your referring to the iat (intake air temp) sensor. the only sensor you don't need would be a maf

MAP, TPS, IAT, CLT (coolant temp) are the ones that LT1's use.

The main OL table uses RPM vs. MAP vs. Coolant Temp.

VE table uses MAP(Kpa) vs. RPM

PE Tables are: %Change vs. Coolant temp
%Change vs. RPM



The injector constant is I found out a picky one also. Years ago I bought Holley 50lb
injectors and they did not come with the table for it and no info out there anywhere for
them, including Holley doesn't have them either. I found out if they are not right it can set your VE tables high. On a limb I tried MSD's constants and the VE tables were 13% lower. Solomond was the one who told me about that the constant issue. Moral of the story there......just dont go buy injectors from anyone or any company....

Thanks guys, the IAT sensor is the one I am guessing I need to buy. I plan on installing it in my air intake line. Thanks for the replies.
