We get about 2 weeks of coldish weather here and I have a TBI mounted IAT that heatsoaks. My MAT table has been fairly well modified. Had fairly bad restart issues that led me along that path.lagos wrote:slow_hemi6 wrote:Sensors can heatsoak and give false readings of the air temp.

Its true but a heat soaked sensor should read a higher temperature, and make the car run leaner.
I have found heat soak to only be an issue in the summer time when the car is at idle or has been turned off and restarted. Thats when IAT start to climb to unrealistic values above 120F. In those cases, you should adjust the MAT compensation table to avoid the engine running lean.
