You can run HiRes Rafa. You'll have to get Manny to install a .1nF Capacitor between JS8 and GND. I can adjust their MSQ for you if you feel the need to run that with your parallel install. Are you mostly interested in their ignition table? The other things like acceleration enrichment won't work with your injectors without some adjustment.
You have PM.
You have PM.
BTW, I assume the capacitor you mention shouldn't be too difficult to get locally; I'm I right? This would be a good time to do it also because we're going to be doing the fan control mod this week also.
Thanks,
Rafa

Heres a question.
How did you guys determine the 8.0 crank dwell, and the 1.0 min discharge, Its higher then the 94-95 cars. Any advantages?
I also didnt compare the spark tables of the 9495 msq and the 9697, are they different? If so would that spark table work on a non hi res version of the firmware?

Lots of testing with a scope and a dyno. They are the proper settings for use on the MM9697 cars. In reality you could go longer on cranking dwell, the stock ECU does, but we don't really need to so we didn't.
Yes the spark tables are a bit different from the MM9495 to MM9697, not much but a little. And yes they can be exported into .vex files and brought into another map used on different firmware.

The ignition coil has to be carefully controlled to deliver a high voltage pulse to the spark plug. The ignition coil is charged a short time prior to delivery of the high voltage pulse. The coil will continue to deliver the high voltage for the spark plug for a predetermined amount of time, called spark dwell. The dwell time is very important to produce a sustained spark inside a spark ignition engine. The dwell time insures proper ignition within the engine. The charge and dwell times of a spark ignition engine will be controlled by the microcontroller's timers.

FoundSoul; how about for those who've done the COP conversion? Would the cranking dwell also be any different than the one being used in 91/95 cars? I ask because my cranking dwell was 3.5 instead of the 2.5 suggested by braineack and I wasn't facing any issues that I could notice.

On the AE- we set the MM9697 up for RPM based AE using TPSdot. Works well, simple to tune.
