Installed a LT4 supercharger on an LT1. The LT4 supercharger has a 4 wire TMAP sensor in the rear location. The conversion harness connects between the MAF, extends to the LT1 3 wire MAP connector...

Any additional help would be great. I’ll plan on the IAT sensor in the front MAP location, as I’m using the rear MAP location for a 3 bar sensor. I need a bit more time as I’ve decided to install...

Just finishing up a LT4 supercharger install on a LT1 stingray. Id like to get the IAT sensor out of the MAF with a breakout harness. My though is to remove the front OEM MAP from the supercharger...

Actually the AFR is rich from the factory. About 12.2 - 12.5 is good place to be.

Trying load the stock tune file back on a previously licensed vehicle. Getting the message to license the vehicle and purchase credits. Anyone know why this is happening?

So the AF under WOT is ~ 12. My understanding is the AF should be closer to 12.4. Is spraying less Meth or adjusting the PE table the preferred method to lean the fuel mixture.

I had a similar issue with my boosted C7 in the 3500-4000 rpm range. I ended up leaning it out a bit in that area on the PE table and the KR cleared up.

There is some aggressive timing reduction in the IAT table. The car also has he IAT breakout from the MAF.

Ok makes sense. I guess the only risk of tuning the PE this way, is if a failure of the Methanol system occurs.

C7 LT1 with ECS Supercharger, 10psi and Alky Kit (100% methanol) I notice the PE table is quite lean between 3300 - 5600 rpm (1.000) Is this typical with tunes utilizing Methanol as supplemental...

Working on a 408 LS3, twin turbo, with GMPP LSA ECM and harness. The car will start but idles at 2200 rpm. I'm using a LSA throttle body from a CTSV. I notice on the scan the throttle position is at...
