    Re: Megajolt conversion

    Ok so... using the old coil wires worked BUT, its firing but I'm pretty sure it's out of time cause it is spitting hard and will die unless I hold the throttle.
    Got fuel and spark now though, so progress.

    coil on plug are a little hard to trouble shoot for like you said hard to tell whats firing when with out a scope on each leg.

    Re: Megajolt conversion

    I'm hoping maybe just need to readjust the vr sensor. Followed the install directions to the T, but I'll have to recheck sensor alignment. Wheel is set 9 teeth counterclockwise from missing tooth being at sensor. At tdc, missing tooth is pointed down.

    If you find the data sheet on the sensor see what "reach" it has. there usually rated for 1,3,6 mm reach depending by design.

    Re: Megajolt conversion

    Well I think I figured it out and it boils down to me overthinking things...
    I was trying to use the old firing order for the distributor... 1342, with the new coilpack. But, it hit me today... I shouldn't be doing that. The new coil will just literally go 1234 in relation to where those are on the coil itself.

    I hooked the distributor back up cause I have to get to work and when I went to start it, was spitting and sputtering just like it did the other day with the edis hooked up. I had crossed two plug wires. That's when above hit me.

    Re: Megajolt conversion

    Got it to run but it's kind of rough. Spits when it first starts. Wont idle on it's own and when it dies it does a hellacious backfire.

    Re: Megajolt conversion

    After digging, have figured out that my timing is a degree out.
    Pretty much explains everything.

    Re: Megajolt conversion

    Mechanical or spark timing? Just curious... Is the spark timing set by a laptop with that thing?

    Re: Megajolt conversion

    mechanical timing is off a hair. Thought I had it set when the engine was out but tightening the tensioner must've shifted it slightly. Or, belt stretched when I was taking crank pulley off that first time and it was a pain in the ass. Explains why I had to turn distributor a bit to smooth out idle. Guess I should've realized it then but was too worried about getting it running cause I needed it for work at the time.

    Yea, you can alter the timing with a laptop.

    Re: Megajolt conversion

    Cam is set to perfect tdc in the following pictures.

    This is the timing mark on my flywheel.


    This is what the pointer is at. You can just see the two marks which is why I posted 1st pic so you know what they look like.


    It looks like it is pointing in the middle of the two lines so it is in fact off just slightly.
    Now my question is... and I know on a stock flywheel you would us the "T" as your set line. This however, is not a stock flywheel so is the "T" on this one implying that the line right next to it is "time"? If it were the engine running time, it wouldn't be that close to the set mark.

    You might have to verify that TDC the piston is all the way to the top at dwell with something in the spark plug hole and go from there.

    The flywheel is not stock? i dont recognize those marks.

    Re: Megajolt conversion

    I did make sure it's for sure at tdc, pulled plug, shone light in, stuck a small rod in there to feel piston moving, etc etc

    flywheel is an Unorthadox racing lightweight.
    I cant find any documentation for it even on google. Found stuff for underdrive pulleys by them but nothing for the flywheel.

    Re: Megajolt conversion

    if the piston is at tdc and those lines dont match up then they aren't in the right place, you cant even use them for your spark timing. pop the valve cover off and look at the cam pulley

    Well technically the line might not be. If you check TDC like mentioned above then you remark the flywheel.

    I always check every motor I mess with. Most domestics the stock style balancer is rubber and slips over time and the mark will be off from TDC.

    Moral of the story CHECK EVERYTHING.

    Re: Megajolt conversion

    So, after finally finding some info on the flywheel, it looks like I'm supposed to use the line next to the T as my base timing when replacing the timing belt. When I had the engine out and changed the belt, I used the actual "T" as the mark since that's what we're supposed to do, but didn't take into consideration that the flywheel isn't stock. In the end, I set myself a tooth off from the get go. Explains why it backfires like hell on off throttle conditions and is cranky sometimes when starting. I just figured it was an after effect of the carbs. Live and learn I suppose.
    Next day off I'll reset the timing and since I have a fresh belt on hand, go ahead an swap a new belt on. After that, I go on vacation to my parents in Texas. Should be a fun drive. I did drive it to Knoxville as a long distance test which is about 1 1/2 hours from me and she did great there and back so hopefully TX will be fine. Averaged about 22 mpg which is better than I expected, lol.
    I'll update this thread after vacation or if I get my dad to help me with it whilst I'm there.

    Re: Megajolt conversion

    Alright, we're back...

    Car made it like a champ to Texas and back. 1900 miles both ways. Only issue I had was one of my exhaust plugs started to back out and was making a hell of a racket. Actually got great gas mileage.. averaged out to around 28mpg. With how this car is modified, I was quite impressed. But, interstate driving isn't too hard on mpg so there's that.

    Going to swap on a new timing belt tomorrow and reset the timing to where it should be since I'm a degree off. Water pump needs to be swapped out as well so going to go ahead and do that. It's had a bent shaft for a while now but somehow never leaked.

    After that, we'll go from there and see if I can get this thing running properly.

    Re: Megajolt conversion

    New belt on, she is timed perfectly. Hit it with a light and everything.
    Runs much better and is smoother on idle. Still backfires like a slut when letting off throttle, but that's dcoe life I suppose.

    I wish, but with the header the way it is, I'd have to get a bung welded in at the collector to get a good reading.
