Just curious about using negative values in Tuner Studio for ignition timing values, specifically in the Left most bins. I know I could "trick" the MS v3.77 by adjusting the offset in TS, but was just wondering, could you just use a negative (-) symbol in front of a numeral to indicate ATDC? Would ...

Just a quick note to update the status of this project. I pretty much have everything now buttoned up, and have it running really good, (although I haven't even touched the default crank PW and ASE, which seem really good anyway) It now starts well, and revs flawlessly to redline, and beyond. I have ...

:oops: I didn't get back here quick enough, as I now have my tail between my legs. I failed to analyze the most basic settings of timing advance, I had the lowest rpm bins set at 8 deg btdc, (thought it was 5) but realized that this is a very large one cylinder engine, and apparently any amount of ...

So I have been tuning this project, and messing with different turbos and such, and recieved my new flywheel, so have installed it. It runs good, but it still has a bad habit of throwing some very advanced sparks while cranking, like about 90 degrees before TDC. This causes a violent crank "decel ...

Just a quick update....Had it on the chassis dyno this weekend to tune in the VE table, and everything pretty much worked flawlessly, Started great almost everytime, and reved to redline very smoohly, and it has never run so smoothly, quiet, and exhaust temps much, much cooler. :) I still have cam ...

Great minds think alike! ha ha! I am happy to say (knock on wood) that switching to 84 on "cam tooth" eliminated the resets at 4600rpm, and runs clean up to rev limit, tried it many times, never faulters, although I have not yet had it under a load, but have finally been able to tune the fuel table ...

Thanks Grippo, I was going to try the cam tooth =84, or 83 even, to give a little more lee-way, but kinda forgot, and didn't fully understand the possible outcome. I will try 84, but if you are sure the signal is causing a double trigger, I can make a bracket and just dump that CDI VR sensor, (if it ...

OK, those are now junk pics, lets try this

Here are the pics I wanted to post above, but had to reduce the size to post them, so here they are

Got a little time to dabble with it today, and no the fuel is OK, it's re-setting, although never see a trigger fix, or the sync status change, but do notice the tach gauge drop, and the "tach counter" on the black screen always reset to 0 when the backfire/rpm stall happens, It was origionally at ...
