How many are available for the 2.8? Gimme some links.

Positive cable didn't rub through on a new motor mount/bracket, did it?

Do the Weber.....

How did you adjust it? by the seat of your pants, or per the instructions?

It would run like $#!&, but doesn't it do that already?

But if you've already got a Renix....and have the tech support available here, I say go for it.

It's a factory added "crush" disguised as clearance for the front exhaust pipe to driveshaft clearance. The crush can be eliminated as long as the pipe is routed differently. I have my local muffler shop fab them up on the vehicle. The "crush" was put there to restrict the exhaust flow so the catalytic converter would start working sooner.

Absolutely. You can use the ECU from an 89 to 90 auto trans equipped MJ or XJ in either an auto or stick vehicle. The ECU from a stick trans XJ or MJ is best used only in a vehicle equipped with a stick.

Actually, the HO had the same cam as Renix through about 95. 182 HP was in 89 and 90. 87 was 173, 88 was 177. Put an 89 or 90 ECU in your 87 or 88 and feel the difference!! Torque was about the same and horsepower in the HO was only in the higher RPM ranges. I'm gonna run a stroker on a Renix ECU. Ain't skeered. It's not "limited", just basic.

Oh yeah. ^^.

We want to make sure you're not Uncle Bob here. LOL. 1000 RPM is kinda high. Did you follow the instructions above?

Lots of minor gains that add up to noticeable gain. Did I ever post this here? HO myth buster Renix in 90 made 182 HP. HO in 91 made 190 HP. That's 8 HP difference. HO only made more HP than Renix at higher RPMs and not a bit more torque. HO had 58 mm throttle body versus a 52 mm throttle body on a Renix and also had a better design header. See where I'm going with this? The whole 8HP was not mostly from the head, but from the bigger TB and better exhaust manifold. Put a 60mm TB from www.strokedjeep.com on your present head, eliminate the "crush" in your headpipe with proper re-routing, and go for it. HO stands for Highly Overrated. __________________

I will disagree with the last statement. There are gains to be had with a Renix from an advanced CPS, indexed distributor, 60mm throttle body, and eliminating the "crush" in the downpipe. The addition of an HO exhaust manifold will add some more gain.

Yep.

Which screw did you turn?

Excellent idea to check them. In my Tech Photos somewhere on CC, there's a diagram of the routing. Here it is!! http://comancheclub.com/topic/43691-jeep-technical-photos/

They might. Based on flow rate needed for the engine at WOT and the 80% rule. The pulse from the ECU has to be able to REDUCE the fuel flow at idle/low speed enough that it passes emissions.

Tach gets it's signal from the ICM....... C on the connector. Green with tracer.

Yes this is true. Swapping injectors is for flow/spray pattern only. Injectors have what's called a "duty cycle" which is controlled by the ECU. Only way to get more flow from the injector is to tweak/program the ECU. So, based on your stated logic- An injector from 305 Chevy will deliver the exact amount of fuel as will the injector in my 2.5? Not that simple. The flow rate of the individual injector comes into play. A real big injector will not trim back enough given a certain pulse from the ECU to allow the idle to be lean enough.

The electronics aren't worth it. Here's a little thing I wrote about the HO. HO myth buster Renix in 90 made 182 HP. HO in 91 made 190 HP. That's 8 HP difference. HO only made more HP than Renix at higher RPMs and not a bit more torque. HO had 58 mm throttle body versus a 52 mm throttle body on a Renix and also had a better design header. See where I'm going with this? The whole 8HP was not mostly from the head, but from the bigger TB and better exhaust manifold. Put a 60mm TB from www.strokedjeep.com on your present head, eliminate the "crush" in your headpipe with proper re-routing, and go for it. HO stands for Highly Overrated. __________________ I've also done a few conversions of HO into Renix using Renix electronics with excellent success.

Get the Weber.

I think it detracts from the site. I never look at it.

Click on the link in my signature and do posts 1 through 5, and maybe 27. What brand plugs did you use? Definitely replace the cap, rotor, and wires. Make sure your intake manifold bolts haven't loosened up.

Woohoo. Hoping for a good report tomorrow!!!!!
