Put the timing light on mine the other day and I'm at an unreal 27* total and initial. I have a locked late model dizzy w/o any weights. My orange box knocks off 5* of timing at around 4,000 rpm so I'm down to around 23*. This is with race fuel. Later

Ryan, I thought I remembered you saying you were running 23* on yours. So you are locked, no advance at all, and just the 5* retard. Wow that is kind of surprising but obviously it's working for you.

Maybe I'll have a 'race' spark map and a 'street' spark map. Easy enough to do... in fact I probably should.

I will say, when I first fired mine up after installing the locked dist, it showed about 30* initial on the timing light. Thing is, it sounded really good! I really need to check the timing mark on the dampener to see whether it's off. I've always felt that the timing mark on this car was slipped to the (advanced, making it) retarded side. Will see tonight.

I was at 23* total but last year I bumped it up. I have no way to tell at speed if my timing is backing down but in park it does. No advance, my dizzy is gutted. Later

My balancer mark was a full 10* advanced! Meaning I've been running 10* retarded all this time... Shoot...

Spent half the day chasing down a persistent misfire, of course I ran all around the problem, assuming it was Megasquirt, or a phase problem, or something. At the end of the day I discovered I could kill the engine by wiggling the coil wire There's something wrong in the weatherpak connector. Ah, one thing or another. At least it's something I can fix.

Car has a lot more torque since I set the timing correctly...

Note to MS II users: tuning fuel and spark simultaneously sucks Actually troubleshooting a new ignition install and tuning fuel sucks. Best to get it tuned up on one or the other and do them one at a time. End of rant.

I messed around with it some more last night. I swapped back to the stock coil, with no real change in the misfiring. So I can't blame the e-core coil I have been using. I went back and forth on the tuning, and everything was really inconsistent. One minute the whole table would be too lean, then too rich. Back and forth.

Then, I changed the number of squirts under injection control. For no particular reason I had it set to 6 squirts per rev. I'd thought previously this was too high but it seemed to work. Last night I set it down to 3 squirts per rev. Instantly everything smoothed out, and guess what - no more misfire. I took it down the road a couple of times to check. I crossed my fingers and put it away last night. I'm going to square the rat's nest of wiring away, reconnect the e-core, and evaluate it from there. Chances are very good that I'll take Lou's suggestion and do the turbo install after Kearney. I have about five or six days between now and then that I could work on the car and I don't want it down for the race.

I do expect a better timeslip this time though. I am no longer able to keep the rear wheels from spinning while simulating a footbrake full throttle stage. That is new for this car and I attribute it to the improved timing accuracy. It is noticeably torquier and quicker.

I'll feel better doing a methodical install rather than be rushed about it too.

Sounds like real progress you can build on. A better NA timeslip is a good goal for this year...
