Alright, I got a 350 TPI from a '90 Camaro Z28, harness, comp. tranny, and all accesories. The only question is what do I do with the vss so I won't get a "check engine" light? I live in California, home of the toughest smog laws, so it's gotta pass. As long as the check engine light is functional, and I don't have any codes thrown, I'm sure I'll pass.

What about the book "TPI swappers guide"? Any good?

And finally:

Yes I will be combing the boards looking for info, I haven't found an answer to this though.

Thanks.

 

Since you have a complete setup, you shouldnt have to do anything with the VSS, just leave the thing plugged in. The computer wont know if you hookup the output or not.

 

So I take it that the output goes to the speedo? Then I could just buy an electric speedo from say Autometer, hook it up to the output, (which is where?), and everything would be kosher?


One last thing, it's from a '91, not a '90.

 

90 and 91 are the same so no biggie there. Yes you could use the output and feed an autometer, one thing you might want to consider is that the autometers calibration is based off of you measuring a 2 mile distance, pushing the button, carefully driving exactly 2 miles and then pushing the button again. now the sender they sell for it which hooks up with no calibration as long as you have the correct speedometer gears is 16,000 pulse / mile and the stock output from the computer is 4,000 pulse / mile, if you wanted to be able to just hook it up and only use the correct speedometer gears to calibrate things, I am quite sure, however havent tried this, that you can get a dakota digital SGI5 box, feed the computers output into this, set it to multiply the signal 4x, which i believe is the max it will do, and then you've got your autometer speedometer hooked up and calibrated with no trouble. Similarly you could run a speedo drive gear setup thats a little under the correct, and then use the sgi5 at a lower rate somewhere in the 3.xxx range and then fine tune the calibration also.

If you do not want to use an aftermarket speedometer you can get the cable speedometer drive insert for the trans and painless wiring sells a 4 pulse sender with speedometer cable drive pass through enabling you to keep the cable drive setup.

 

A as far as the TPI Swapers guide dont waste you'r money on all it is a book with diagnostics codes good if you need that stuff.But nothing like I thought it would be.

 

hey whee did u get harness for your El Camino because i have an 86 grand prix which i believe is closley related to the El Camino

 

I got everything from a Camaro. Yeah, if the Grand Prix is a "G" body, then it's the same chassis. Same as the Grand National, the Regal, the Malibu, Cutlass, and others. I'm hoping that everything will fit.

 

stinger, was their anything you had to do like modify the harness to get it to work in a gbody

 

I don't have it in yet, I just got it. I need to switch places with my Rivera, and I'm having brake trouble right now.

 

can i use the canister for the emission from the 86 elcamino this is a 350 tpi that I'm installing
