need to verify correct HPT inputs for IAT and boost
Could those of you with ZR1 (or Gen 4 ecm really) verify something for me on which sensor I should use for monitoring IAT after blower and displaying boost on the V3.x of HPT?
For IAT past blower I have the "Intake Air Temp (SAE)"
I'm also monitoring "Intake Air Temp 2" which I believe in my case is the pre blower temp, at the MAF -could be wrong though! SAE is about 20* higher than IAT2 at idle in the driveway (while I mess around with setting up hpt)
For boost I'm using the "Boost" under the "Math" drop down selection. That seems to work fine, though I notice it is much faster at registering boost than the gauge in the dash while reving in neutral (it'll show 3-4psi while the gauge on the dash barely hits 0 from coming up the vac side. They do both agree at idle on the reading though)
