I'm new to HPT and had a few questions.
I bought a hot rod a while ago that had a normally aspirated 5.3L Chevy truck motor in it mated to a 4L60E. The harness/computer is a 411 GM unit with a wiring harness/tune from CBM motorsports in Ontario, CA and is most likely an off the shelf tune from them as while it is good in some areas, it lacks in others. The engine setup as installed from CBM is (I'm assuming) a speed density setup as there is no MAF sensor installed. I do have a constant check engine light with MAF codes showing input voltage high and input voltage low (P102/103) as there is no sensor installed but that's another issue...
I am in the process of installing a Vortech supercharger and am now at the point of dealing with the tuning now that it is forced-air. The supercharger was not a kit, it was a custom build that I made all of the brackets, intake piping, etc. so there are no off the shelf pieces that will really help me out.
My plan with the addition of the supercharger is to go to a 2-bar SD OS using HPT.
Here are my questions:
Will I be able to utilize any of the existing map or will I need to start with a new base map?
With going to the 2-bar SD setup, what changes will be required other than changing out the stock MAP sensor with the 2-bar sensor? Any other hardware items that I'm not thinking of?
Go easy on me....I'm new to HPT but have some history with other platforms over the years.
