porting the throttle body (while I can't speak to its dyno numbers) was one of the best mods I did to the car... it makes the car a LOT more fun to drive and actually gives you more control over your power...

Though I THINK I picked up a few hp from it..

I have the LY6 throttle body too. Did you port it yourself? If not, is there someone here in Georgia who does? Thanks!

How did you guys wire up the OBDII port?

I'm planning on using a different ECU at some point in the future - while the e38 is a good ecu, there are better ones out there (I can't complain though, it came with the motor). I know that newer GM ecu's have the class 2 serial data outputs necessary to drive class 2 gauge clusters.

I was considering going a different ECM route myself but I bit the bullet and did the HPtuners investment so Im going to run this and see how it goes. I lost my easy access to alldata though and I dont have the pinouts for the OBDII port so if you guys have or anyone has a schem Id appreciate it.

Im so close to firing this thing up....

Im down to my last details now I have my swap running good but my wiring schem doesnt clearly show which pic I should wire the t56 VSS into for the PCM feed. Im thinking its pin 72 VSS LO 822 lt grn/blk

What did you guys use?

Cam,
I used pin 71, OG/BLK for high signal, and pin 72, YE/BLK for the low signal.
I am using an aftermarket speedo, and ran the leads to the speedo parallel from the ECU.
My scanner reads 158 MPH all the time, but the speedo reads correctly.

Thanks. I too have an aftermarket speedo and its already wired and working fine straight off the VSS feed from the trans. I was just a bit unsure of which pins to wire the VSS feed into the PCM for its needs is all.

Thanks for pointing that out to me. I think I might try to do it myself. What's the worst that can happen?
