    Removal of MEFI 4 system from 6.2L V8

    I've tried getting idle a little lower, and it just hurts hot restarts. I've had an alpha 1 gen 2 on the last rig, and the engagement of the duo is much smoother even with the idle at 750. It doesnt bang or thud. When this system was fuelie, I had the idle at 650...... I think the other factor...

    Removal of MEFI 4 system from 6.2L V8

    Been making some progress on my project. Engine rotated with cylinder #1 at TDC and distributor installed. Sort of a little disappointed with this unit. No real clear manual included other than a wiring diagram. No reference for base timing other than the online manual that's listed above...

    Removal of MEFI 4 system from 6.2L V8

    So the UPS man brought a bunch of goodies yesterday. I haven't gotten around to being assembling yet. But I did take inventory. I have a question regarding the Voyager Distributor. It came with a wiring diagram explaining wiring for installation, simple and straight forward. I downloaded this...

    Removal of MEFI 4 system from 6.2L V8

    AllDodge, again I appreciate your help, but that pic above was from the carb 4 cyl harness that was on ebay. I bought that harness, and we'll see how it goes, if a v6 or v8 harness pops up, I may just buy that and sell the 4 cyl harness. Please understand I'm not criticizing you, I understand...

    Removal of MEFI 4 system from 6.2L V8

    Thanks for all your thoughts AllDodge. I really appreciate it. I wasn't tal king about coolant temp, but the brown wires going to the risers/elbows on the exhaust. It's a brown wire with a 90? rubber straight push on connector. II'm pretty certain they are overtemp warnings for the...

    Removal of MEFI 4 system from 6.2L V8

    Tail_Gunner, whelp I went to an "expert" and fully disclosed the equipment I had including: cam, compression ratio, heads, displacement, manifold and injector by part number. (using the supplied form) I trusted an established business. Spent $400 clams on reflashing the ECM, and the time, effort...

    Removal of MEFI 4 system from 6.2L V8

    Thanks Bondo. So after math homework (my 10 yr olds) I made a bunch of progress disassembling last night. Here's about where I started. Here's about where I ended. The MEFI 4 complete wiring harness has been removed and each of the connector labeled where they go. Manifold, coil...

    Removal of MEFI 4 system from 6.2L V8

    So here's my story, in 2011 I bought a very low hours immaculate condition Four Winns Horizon 220 with a cracked block and cracked exhaust manifolds. The previous owner, who recently relocated from Florida, failed to winterize the engine and well......she froze. I bought her knowing this, and...
