MSII and stock ECU compatability

Nism02 · 2008-09-27 19:08:57

I voltage spiked my stock ECU, and lost the signal sent to the 2nd and 3rd coilpacks... so, now I'm running on cylinders...

I want to run a megasquirt II system,

Could I run the stock ECU to control the auxillary systems, and guages, but run all ignition, fuel, etc from the MSII?

I'm having trouble getting ahold of the ECU that I want, plus, reflash and dealing with NATS... So, I'm wondering if this setup would work...
thanks.

hed have to get it done pretty quickly to beat inspected to second MS running timing. but it would cost alot more than getting a new ecu and theres still the fact that nobody actually has a damn spark map for this car hiedis got an srt4 map that works good but if your not a pretty good tuner i would recommend starting with a spark map

actually,

ECU 400-800
reflash for my car, and NATS reflash
and retuning

Plus I want a stand alone anywaz...

Question, pimpsmurf, you said if I'm not planning on boosting.... I've got a fully built engine, and I'm definatey planning on boosting, thats why I was looking into the MSII, would you still recommend the MSI?

ecu reflash, nats reflash... what ? I bought a brand new ecu from nissan for $400 got it installed for $80 and i have nats and whatnot. and what about ecu retuning?

BUT... if you want a standalone anyways then yea get an MS from gurov. just make sure you read alot about spark tuning becuz shit can go wrong QUICK

there's a few more differences in the ms2 code, one being that you can tune MAP+TPS blend for accel enrichments, it's a lot tougher to tune them, but they respond slightly better, again, more of a pain to tune.

inspected's ecu is wired to run ignition just like all the other boxes that i make, but he's not goign to run ignition quite yet.

oh, keep in mind, an external trigger wheel is absolute necessity for ignition control on the spec
