performance ECU

[jbxx]

Anybody know where to find a Mopar Performance # P4529334 (Bendix # P4532129)
upgraded ECU (Renix)?

GL on finding a new one. I had my tb bored out to 60mm, installed a high-alt CKP(adds 5* of base timing which I've read is comparable to the performance ECU), and installed the 23.2# gray-top injectors from my 96 XJ(they're 20.7# on the renix 39spi rail), and the eliminator is definitely peppier.

MP stopped making them a few years ago. You might get lucky and find a used one in Ebay.

high-alt CKP
as in a high altitude crank position sensor? if thats what it is then where do you get them? and is it just clocked at a different spot then a normal one?

[gradon]

Yes, it's offset on the bracket(towards the passenger side, iirc) instead of centered. It's a renix only part I picked up from Amazon for ~$37. Standard PC307.

will that high altitude cp work with a 97 ecu?

[gradon]

The high-alt cps was only available for the renix ecu. I have read of someone who slotted a stock one and mounted it closer to the passenger side(don't recall how many * they got out of it).
