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. 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 |
Yeah, you should be able to get it locally no problem.

hehe... time to sell mine to upgrade to full standalone!! (cant do it with my current one because i have a/c and i want to use it)

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. |
What advantage does a long dwell provide at cranking?
I have tried googling but havent netted much info on ignition dwell. Can the AE settings be ported to a non hires firm as well? |

Longer dwell creates a "longer" spark output so it will fire better when cold.
sounds good to me, I'll give that a try tomorrow :) |

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. |

^ if aint broken dont fix it.

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.

Oh well.. Hopefully we get a unit soon. I've got money in my pocket and ready to buy once we can purchase a complete plug and play unit for the NB with some good baseline turbo files. |
Now just make a PNP unit that can falsify the emissions information through the diag port and you are golden.
|
Are you guys using TPS based AE or RPM Based? I see you have changed the values for TPS based, and you have enabled RPM based as well.
So which is the one that is used? |

On the AE- we set the MM9697 up for RPM based AE using TPSdot. Works well, simple to tune. |
Just market it as "offroad use only" and you will be safe.;-)
On the AE- I still dont understand how you guys tune it. All I know is that when I set it out of bounds the car stumbles when I give it abrupt throttle. Otherwise with the 9495 values I never had a problem or noticed a problem. |
Just use their v/s values then adjust the pw's for your injectors. You can use the PW adjustment calculator in the sticky to get it close. Then adjust from there while you sit in your parking spot revving your car while people look funny at you.
