97 K2500 PCM Help

[rstroh]

What’s up everyone! It’s been a very long time since I posted here, but this is the best place on the next for this type of knowledge and I need some help. I’m not very versed in OBDII PCMS but I picked up a 1997 k1500 5.0 4wd truck, the kid I bought it from put a crate vortec 350 in it.

Since I bought it I put a lift kit and 35s on it, and my msd ignition. I also basically turned it into a light duty 2500, with my 14 bolt semi float, rear 2500 springs, and geared to 4.88 out of my other lifted truck.

I was wondering 1) can I get a computer from the same year(s) truck that is a light duty 2500 with a 350 and use it, if I can what code computer would I be looking for and 2) I’d like to reprogram my speedo, and would like to know which tuning software and hardware comes recommended for the OBDII trucks.

I have tunerpro already ready bc I had a moates setup on my 94... thanks for all the help in advanced and thank you for having me back!

0411 swap it and don't look back IMO. That is coming from someone that has Tunercats OBD2 and HPTuners. I have had both with good tunes in the same 97 Express van. 0411 hands down runs better than the Black Box.

How hard was the swap? I think I vaguely remember something about a guy named lextech that has all the wiring pin outs and tells you what to add and what not. And what bass map did you start with? Out of what truck? I think it’s supposed to be the 01-02 express right?

I started with an 02 Chevy Express. I later swapped that PCM for a 2005 PCM with a Mexico GMT800 5.7 based tune.

my truck is a 5 speed, does tunercat or hp tuner give you the capability to change the transmission setup as well, from A/T to M/T?

The 02 Express van shared the same operating system as the LS trucks. You can segment swap the manual trans stuff into the tune with HP Tuners or TunerCats. Just have to grab a matching year 4.8 or 6.0L truck file
