i recently bought a yj jeep with what the guys says is suppose to be a 383. but only thing i can really see without pulling it apart is it has aluminum heads. this engine runs like ****,
is there anyone out there that can still tune these old dinasours? thanks in advance!!!

or should i just ls swap it!??

I'd be checking a forum for Gen II engines. This is an LS forum

Not being a jerk, I honestly think you'll have better luck there.

I used to tune them as well as the TBI cars and LT1s. PM me if you got questions

Just curious, what is actually used to tune these? Is it the same thing the old Buick guys used back in the day?

Last time I fiddled with one swore I'd never touch that old ECU again...
Depending on the generation they were basically analog , 1 step up from TBI,,,
The ECU's are so old that the capacitors are drying out.. Refurb can run 400+ dollars
to get a guy who is good enough at that generation of electronics on the job..

I'd run a Microsquirt and never look back..

Have the same issues with my 94 Jeep Wrangler.. ECU is the Jurassic edition and I don't mean the movie.. LOL

MLCCs dont "dry out" and have been used in cars since the late 70's & they are very robust. I don't know what you're doing to your computers but I've never had those kind of problems.
