No, just curious if FAST makes a retrofit harness for the TPI for use with the XFI, or if you had to modify one to work.


So the EFI will control an electronic transmission?

Well, not really...been laid up for a couple weeks with a banged up ankle!

Got the fuel regulater mounted in the fuel rail, so that part just needs the gauge.

Waiting on a couple thousand to come in to buy my FAST XFI system, then i should have lots to do. Right now im just plugging away at little stuff to keep busy, feels good to be able to stand up again:lol:
Guys over at -----------------have been really helpful, making sure i dont buy the wrong part or something i dont need. This really helps when you have no idea what your doing!

My main problem is the PCV system. Bought the valve yesterday to put in the vc, but that is all i know of the stock system. Dunno where it gets plugged into the plenum....searched and searched, read and read, but cant find any actual pictures of what the system looks like. Found some diagrams, so i know where it goes, just not how it actually hooks up with the fittings and size of vacuum lines...ill keep searching, i know the info is out there, maybe buy an old assembly manual for an '85 corvette

Been meanin' to post up on your build thread to see what youre up to...i know you made progress

Thanks for lookin

In my old show truck s10 I used the glove box to hold my pcm, HATED IT. I would suggest behind and under the dash.

I was just wondering where you bought the XFI ECM.

All the mail order speed shops carry it for less then i paid.....the owner of the company where i bought it, tried the bait and switch on me. On friday, they said they ordered it. Come tuesday, they said it had arrived. Curious, since it wasnt wrapped in plastic, i opened the box. It was damaged from mounting, so i asked him. He said that it was just mocked up. OK, turned it over, and the date of manufactor was 2008.

I refused to take it, and he ordered another one that arrived on thursday. Just left a untrusting feeling, but he did make it right. I wasnt going to say anything, but since you asked. I have found another speed shop in my area with a dyno, so i will be using him for the final tune

Finally, i have an idea of where to mount it....passenger side kick panel. Thanks Dale

My upper plenum is the correct for my year, 90-92, so it has a threaded boss for the bracket on what would be the rear, right side. It has an L-shaped bracket. I made one out of aluminum for a year or so, tell I found a GM one. The map has an elbow that comes out the bottom, and goes right into a vac port.... which your 85 wont have as you mentioned.

You can t some of that off, or I have seen people drill/tap the plenum for extra ports. Or a popular mod is to move the IAT sensor from the bottom of the plenum into the air stream, and then put a hose barb there for more vac ports.

I dont have car with me at moment, so I cant take pics. Will check in a min to see if one of my facebook pics shows it. :edit: nope, will have to take one for you later.

ok, looked. As for ports on the plenum, I have..
1. hvac.. pass side
2. charcoal canister.. pass side
3. map.. pass side
4. brake booster.. left rear
5. fuel pressure.. underside where IAT use to be.

If you want any of these full size, give me a pm with your email addy.

Dude, thank you very much for taking the time, just the info i needed...i dont think the bracket i have is a map bracket, close to that but no cigar. Its gotta go somewhere

Those fat runners look great on there!

Ive never seen a bracket like that before.

You "could" drill n tap that, but your taking a risk of a vac leak. I would look at mounting it else where, like maybe on the same bracket as the coil? You depend on how long your wires are for it.

Correct Sir, I did the 0411 pcm swap so I have true SFI, rather then batch injecting.
