    Thanks guys! Yeah, after I redo all the wiring, and make a mounting bracket for the coil packs, then I'll take it for a spin and give it a tune. I might install the hard rev limiter first though since it will require me to rewire the coil power back to the MegaJolt unit.

    you should re-wire that MJLJ into a USPS box and ship it my way.

Did you put them on a little board in a box or just heat shrink around the diode and put them inline with the wire?

    You can put them on a board but it's kinda overkill. I just soldered the diodes together directly will some wire pigtails to connect to the rest of the wiring. Add lots of heat shrink to make sure nothing shorts out and you're good.

    Now comes the fun part of figuring out a good timing map. Best way to do that is on a brake dyno, but that will cost some money. I could probably reverse engineer a timing map from the stock distributor if I had one to play with. But then that would only get you to stock, not necessarily the best in terms of power.

    Re: 2ndGenGuy's '81 Hatchback MegaJolt Lite JR Conversion

    Yeah the timing map is going to be the fun part. I sorta understand how to do the timing under load, advance it until I ping and back it off a few degrees. But what about idle and cruise? Do I still want it advanced as much as possible? I was playing with the idle timing last night, and it seemed smooth anywhere from 14 up to like 20 degrees. I didn't really take it any higher than that, as I just was trying to figure out the operation. But do I want to advance idle up like that as well? Or just go with where it runs best? Sorta like running it by ear? The local shop here will rent out an hour of dyno time for $80 with a sniffer and let me use it as I please. So I can do as much street testing as I can and then hit the dyno and try to squeeze out a bit more.

    as for the tuning it's really difficult to explain how to street tune, i know a guy that does them really well, obviously better with a dyno, but if you have access to the dyno i'd just work out a map while on it, for 80 bucks it's worth the money in my opinion.

    +1 - its easier to see the tq on a load bareing dyno than by seat of the pants. Get the idle really good then tune WOT after that work on part throttle and cruise.

    I tune my idle for best "tip in" throttle response. on a complete efi engine. For a carb i add timeing until it gets hard to crank when the engine is hot, then i back off ~3 degrees. Your mileage may very, and alot of tuners will tune things differently.

    here is a link that should help you with your spark tune -http://www.msextra.com/doc/ms1extra/MS_Extra_Tuning_Manual.htm#sparkmap

    P.S. congrats on your car and running with out a dizzy.

So I can do as much street testing as I can and then hit the dyno and try to squeeze out a bit more.

    The advance 'till it pings and back off strategy works for some engines but not so much for others. Really the best way is to advance until maximum torque, and then stop. Or stop before then if it starts pinging, but that won't happen unless you have higher compression or REALLY crappy fuel.

    I would imagine this engine is similar to the A20 in that it will like lots of advance (because of the not very optimal combustion chamber). Here's a map that pretty close to what I'm running at the moment:






    This is sort of a hybrid between an A18 distributor vs. a P75 ECU. The heavy advance between 1500 and 2000RPM makes for really zippy throttle response. Before you start tweaking the timing do make sure that the timing you set in the map matches what the engine is actually doing. If it's off then you can either adjust the sensor mounting location or just include an offset in the map to compensate.
