Background - I am very proficient with TBI (GM 7747) tuning and wiring. I've built several of those systems on old Jeeps and have a Moates APU. I'm also Sr. Systems Engineer and very proficient with computer hardware/software.

Goal - buy a GM vortec engine (most likely the 8.1) and install that into my Jeep (mated to my existing NV4500). I'm not particularly interested in actually 'tuning', but rather disabling VAT's and maybe tinkering with the bin a little bit.

I want to buy my own hardware/software (not ship the PCM out to someone).

I already have one of those bluetooth OBDII things - is there a way I can perform the work I need on my phone?

This rig is used for 4x4 purposes only. It's not a DD at all.

Any help is appreciated!
