tuning renix turbo

[88_cherokee]

i am gathering parts to turbo my renix xj but needed advice as to which aem fic to use...anyone with experience that could shed some light?

This is another option you may look into. It can be found here http://www.diyautotune.com/catalog/diypnp-delphi-56pin-unassembled-kit-p-389.html and is a direct swap for our computers. I put one of these in my turbocharged Isuzu trooper this spring and it works great. I plan on using this kit on my renix jeep next year, before I stroke it.

so basically i remove my stock ecu and us that one and tune it with that one?

 

[yenkoz]

Exactly, and the nice part is you don't have to modify your stock wiring harness. So you could always throw your stock ecm back in. I'm really happy with it on my Isuzu trooper, and will definetally be doing it to my Jeep. It is really nice to be able to plug your laptop in and see everything it is doing and modify any parameter you need. And if you get the Tuner studio software and a wideband O2 controller, it will auto tune your main fuel table.

It would work with any brand wideband? The aem one is fairly priced at $165 on ebay

Would that talk to an aw4?

 

[yenkoz]

Yeah it works with all the major brand wideband O2 sensors (innovative, aem, plx etc...). After studying the renix computer, I can't see where it talks to the tcu. That is why it has that funky double TPS sensor on the throttle body. The 91 on up chryco jeeps may be different.

it doesn't need to in a renix jeep. TCU is standalone.

 

[88_cherokee]

the aw4 has its own computer

So where is the one for the Jeep?

 

[yenkoz]

The one for the renix jeeps is the one in the link I provided. They use the Delphi 56 pin connector to plug into the factory wiring harness, the same as most GM's in those years.

I knew it was standalone, thought it got some info from the computer.

only on the later years.

Any progress? If you decided to go MS you can use the stock trigger using the 22-1 wheel coding...

I am turbo'ing a Renix as well but I think i might be farther along...

Nope. Just the TPS, vehhcle speed sensor, NSS etc

I know this is not for a Renix Cherokee but thought it might help since I believe the wiring is pretty similar.

When we installed Megasquirt on our turbo 1995 the only wire we need to run was the TPS signal. Looking back I don't even think that was needed since both computers share the same signal wire. Not sure if you will get as lucky with the Renix TPS. I'd need to look at a wiring diagram.

If the OP hasn't said it, THANKS!
