JS8 is what I'm using-- goes straight to pin11 in the proper location for the cap. Don't go higher than .1uf without proper testing, you could filter out the 2nd trigger altogether...
Guys-- this was the entire holdup on the MM9697. Some of he earlier cars have an occassional hiccup and some never even have that, but the 96-97 cars, about half of them at least, are nasty without this low pass filter cap (really it's a two piece filter circuit, but the resistor was already in circuit).
I spent days on the dyno with the scope . Fun stuff, but I was ready for it to be over... I'm SO glad it's nailed...

I'm SO glad you nailed it, I wouldn't have had a clue how to figure that sucker out.
and now I have a completely missfire free car it's bliss
Would've been easier to solder the leg to JS8 too...... nevermind!

Matt was a big help in the process, as was James and even Bruce Bowling was brought in for his input along the way. It was an international effort .

On the earlier models if you're not seeing the miss with the standard code it's pretty likely you won't with hi-res, but we are more than happy to fit the cap for you at no charge. I don't think everyone will care to, and don't think it's really needed unless you're seeing an issue as it's the 96-97's that really had a problem here, and to a much smaller extent some of the earlier cars. As I said though we're happy to fit it for you at no charge. All new units going forward are going to have this in place, we're changing the spec right now.

Are you guys running unchanged maps with hi-res without any issues? Just easytherming hi-res, flashing, loading your old map untouched (maybe changing those 2 or 3 .01 values to .1 so as to get rid of the warning flagged in audit.log) and then you're all good?
Just curious on your results here...
