I've done it. Yes, runs better. I installed a high energy ignition and a Motorcraft 2100 carb. I know alot of guys run the Weber but the MC is really easy for dumb guys like me to adjust. If you are having issues with that Carter carb/computer or stepper it's a good option.

Short answer;YES!

Long answer; Y-E-S-!

This only works on a 4.2L though.

This is a Picture Guide to Nutter Bypass - JeepForum.com

Also The MC2100 Ford carburetor will be a vast improvement over the Carter BBD.

Lastly take a look at this;
Genuine Junk Yard Genius.com Ignition Upgrade, Jeep 258 CID I-6
I-6 'TeamRush Upgrade' (definitive) - JeepForum.com

It's basically the same parts as a tune up, only it's better since it lessens the chance of crossfire under the cap. the terminals are farther apart.

so basically, you cut the orange and purple near the firewall, and reroute them directly to the orange and purple coming out of the module, thus bypassing the computer under the dash.......

Interesting

Well you cut the orange & purple wires near the module & jump/run them to the distributor. Thing is, the wires change colors by then, to (I think) green & yellow.

Be sure to get it right, & don't forget the ground wire at the distributor must be grounded.

another stupid question. the ford cap and rotor looks like an excellent idea. But...

1. will #1 cylinder be in the same location??

2. do I need the 4.0L wires or will my new 4.2L wires work??

ok after reading the "teamrush" upgrade link again, it appears that as long as my distributer is correctly installed, #1 should not move.

As for the wires, it looks like my stock 4.2L will work but it also looks like the 4.0L wires are shorter, thus allowing a neater install and a shorter path to the plugs.

thanks again!
Jake
