I don't know for sure but I think you would do just the wiring part of the Nutter. This would bypass the computer, provided it would have one. As for the TeamRush I don't know if there is an upgrade for that. Hopefully JeepHammer will chime in and give his advice on that topic.
This is a mute post. The nutter bypass is eliminating the emmision computer, along with the sensors. I live in good ole Michigan, we don't have smog rules, knor have I ever had to get a vehicle inspected.
But from what I have read here in Cali it would never pass, you have it the roughest out of anyone!
Just revisiting this for some current feedback. I am, of course, running into a bunch of tuning issues w/ my existing stock system on my '86 CJ7. If for no other reason than to stop the *****ing from my mechanics I'd like to cut the computer out of the equation. Couple of questions:
1) Are folks in California finding they are able to pass smog inspection w/ the Nutter bypass? Assuming if all the lines are in place it would pass the visual (I recently passed smog but later found several vacuum lines had been plugged w/ BBs).
2) Can someone provide me a link to a thread that documents the definitive step-by-step instructions for the bypass procedure?
Thanks BagusJeep, that was the thread I was looking for. When I searched the forum for Nutter Bypass, I got tons of posts but oddly didn't see this (I know how annoying it is when a Noob doesn't bother to search the forum). Bookmarked it now.
86cj74.2L - yesterday my carb mechanic was telling me the stepper pins weren't moving at all. He was going to try swapping in a new stepper unit that he uses for testing to see if the computer or stepper is dead and is working thru the checklist of various other culprits. Worst case is he will get the pins to a centered position so it will run adequately and then we decide where to go with it. FWIW, he (carb mechanic) is a big advocate of swapping in junkyard 4.0 FI systems or the Howell TBI. Wasn't as bullish on the Mopar FI - something about losing EGR etc. plus higher cost.
I've never seen the stepper fail. Always a chance though.
Its simple. Ignition on and no engine run at a cold start the pins should be centered.
If not then the computer is dead, the stepper is dead, or the wiring is bad.
Show your mechanic the "Adventures Under The Hood Link."
A cheeper fix would be to bypass the computer and buy a non feed back (stepper) carb off a Wagoneer or J pickup. Rebuild it. At my local u pull it yard the carb would cost 15 dollars. Drill out the emulsion tubes and replace bushings if needed and you may not care about fuel injection.
You will go broke quickly paying someone else to learn how to fix your jeep.
The proper place for static stepper pins is with their shoulder showing 1/8" from the back wall. The carb then will set good enough manually to pass the emissions sniffer.
