A friend has a evo 8, speed density V7 map, using omni map sensor and GM IAT.

Car runs great, no problem, but IAT always shows -65 dregrees no matter what! It is connected.

What are we missing? is there something to do on evoscan to be able to read it?

Thanks for your reply

 

are you using fuel temp sensor or maf air temp senor wiring you can set which one in the rom under sd programming (sd iat option )

 

Maf air temp, set up in The rom (0x03) I think

 

evoscan request 3A , check wiring to maf plug or dodgy sensor

 

evoscan request is correct in 3A,

will try with another sensor, and recheck wiring

 

red/ blue wire and black wire at maf plug

 

Tried another sensor, and still the same. Always shows -65 and no change at all

Should the table be adjusted on evoscan?

 

check you have 5volts between the wires with ign on sensor disconnected
