2015 Silverado base EForce Kit comes with a multi-plug harness adapter that incorporates factory MAF and MAP plugs.
However, the harness loom combines the stock 1bar behind Throttle Body with the added Bosch 2.5bar TMAP (0261230042) on side of supercharger.
Calibrating MAP in the file for 2.5bar gives wrong data, but 1bar cal give accurate data (ie 99kpa KOEO, etc). So it seems that it is reading voltage from the stock 1bar sensor, but how do I get it to read the 2.5 TMAP sensor?
The stock TB sensor would not see any boost since before the SC.
Came with SCT but this is cammed with LTHs so sticking with HP. And have wasted 1.5 hrs on hold for Edelbrock and always am "next caller in line"
Ultimately, what puzzle piece might I be missing here?
