89 wrangler 258ci 6 cylinder

I have a question best asked among jeep owners. Has anyone converted the 258 from all that vacuum hoses and the computer box to a msd ignition system. My son and I restored an older car and used a setup for a 302 ford engine with no problem. any answers appreciated.:?:

Most people do a Nutter By Pass.

Did the nutter bypass as I explained in another thread, and it worked wonders for my "89"
Don't mess with the vacuum system, as the EGR has to be in working condition, or other problems may crop up.

I just got an email tonight saying Howell automotive is now carrying Accel fuel injection systems for 4.0L that are programmable with a laptop.
