Thread: '04 Series III w/ MegaSquirt-II -- Ignition

Alright, hit another snag in my plan. It has manifested itself in the form of ignition

According to MS-II documentation, this board was originally designed for one coil/distributor (7 pin HEI for example) and Ford's EDIS systems. Is it possible to have this somehow compatible with GM's DIS? Any insight at all would be highly appreciated. I'll put the pinout for the MS-II board that I have now, and the wiring for the ignition control module.





I have no idea how to proceed at this point. Plz message or reply for more information or if you have any suggestion on how i should continue. thanks for reading.

there was that engine being fired up on the engine stand vid posted on here it had a mega squirt set up so it has to work.

you could always email the guy who did it maybe.

omg wicked, i <3 you so much right now. Haha! I've gotten my drive back XD

lol Yea i have no clue on ignitions stuff but i figured you seeing it work on a 3800 may help lmao

I'll be sure to write up a wiring diagram for the complete wiring of my engine as soon as i get some free time from class this weekend.

Sweet. How's it running? Did you do speed density or hybrid alpha-n?

Mark!!! You made it to the national boards

PLEEEEEEEEEEASE share your wiring diagram. I have a local that wants to try and use MSII on an L67 in a Fiero.

yes details!!!

Finally I've had an account here since the beginning, just never posted. Found the MS thread on google. Guess my plans aren't a secret any more

That's correct. All versions of MS support only bank injection. Both banks will always inject for the same pulse width also. Can't make one richer and one leaner.

They decided it isn't much of a factor at higher rpms because the injectors produce a near steady spray beyond a point. I don't know if I agree with it or not but good long term results are had.

Got mine up and running last night after a jump start from the S10. Haven't driven it yet. Need to get my wideband hooked up first.

Sweet action

(Not my thread) but my megasquirt is MS-I running MSExtra. I'm doing fuel only right now and working out the details of how to do the spark. Rather than completely take control of the C3I away from the stock PCM, I had a different idea that might work. Haven't tried it yet.

Hooking it up for fuel only is really simple though.

Ever heard of the happy knob? It's the thing where you twist the knob and it advances your timing by looking at the IAT sensor table.

I don't know if that's real time or not, but my idea was to just get a digital variable POT and hook it up to the megasquirt. This would essentially let MS command the final 10* of timing, while the rest of the time the car would just go by the PCM base timing.

This would let you keep traction control and knock retard stock, but fine tune the timing table with MS.
