Benefit of renix vs swapping to newer harness

Hello, I have been searching for a while and I still can't find exactly what I'm looking for. Current is 88 xj with blown engine but have a stroker built for it. Stroker includes 91 head and exhaust with 99 intake manifold. I was debating on replacing the harness from a 91-95 but one dont know how hard it will be and two if it is even worth doing. I absolutely HATE the renix tps sensor but I want some opinions from people who have dont this or have thought about it and why they didnt. Any info or even a point in the right direction will help.

Good place to start.

As for the swap it's really only worth doing the harness if you're upgrading to OBDII past that there really isn't a benefit for the amount of work.

Is this off road only? I doubt you'll pass smog.

Smog testing usually isn't a problem if your up-grading the year of the system!

Just keep the Renix.

Use the REnix intake gasket.

Have an O2 sensor bung welded into the headpipe. Harness is long enough.

Unfortunately it's little too late for that. Already had the intake port matched and all that

Re: Benefit of renix vs swapping to newer harness

I'm guessing you're aware of the throttle body/tps issue, right? There's a Megasquirt available that's plug-and-play with the Renix connector. If you have a manual, that would be the way to go. OBD-I isn't worth it other than to change sensors if it's worth that much to you. OBD-II has a bus system that makes it a PITA. Not insurmountable but a lot of work to end up HAVING to pay someone to tune it vs using the auto-tune feature of MS to get you close and play with it from there. MS is in the latest Summit Racing catalog. BIGTIME BABY!!! Other than sensor availability and the frail TPS, there's a lot of love out there for Renix as a "it just works" system vs a more frail "limp home" OBD. There's a few Renix vs OBD threads over on Jeepstrokers worth a read.

Re: Benefit of renix vs swapping to newer harness

You're 100% sure on the head ports and Renix intake and gasket, huh?
I've done 3 Renix intakes to HO heads with no issues.....
