What kind of different wiring is involved? I feel like I'm oversimplifying it. Is there a how-to for just the wiring? Installing the hard parts is nothing to me. Same with tuning. But wiring is not my forte.

Also Sl0wbaltSS stay the **** out of my thread.

What wiring are you talking about? As far as I know you tune with HP Tuners via the diagnostic port using the interface and laptop.

Plug into obd2 port, read entire file, make edits, flash calibration

Doesn't the SC or turbo use electronic boost control? I don't imagine it is as simple as changing the SC/TC tables in my tune without actually wiring them into the ECM.

Que what???

Hp tuners is not a piggy back or independent ecm it is a tuning program you load it on a laptop then use the supplied cable to plug into the obd2 port and load your tune then unplug the laptop and your basically done except for revisions and logging

I'm not asking how to use HPT. I've been using HPT for two years. You guys know this is the L61 section right? L61s don't come with IAT2 sensors and a variety of other things that boosted cars do come with. You can't just throw a blower on the car and not hook it up and expect to calibrate or log the IAT2 sensor or whatever boost control the cars have.

What I'm asking is if there is a how-to on wiring all those things which do not exist on a NA car, to my NA car while retaining the E37 computer.

The how to is around here somewhere. iirc you end up using the ECU's IAT from the maf and wire it to the IAT on the MAP, then there is some map scaling you have to do

You probably can wire in the boost control solenoid BUT i dont think its needed (just pedal it)

For the MAP and IAT wires: the MAP is swaps easy (wires are the same - but you need to adjust tune for it). Take your IAT wire from the MAF and wire it to the IAT wire on the MAP (only works if you use the LSJ 2.5 bar MAP sensor)

You will have to extend the TB wires and the MAF wires.
