    I use the nissan power transistor, i think is better and stronger.
    how would you use the oem transistor on MS3[/quote:1auywxie]
    I've used MS1 and 2 on V3.0 like this.



    Spark inverted NO!

    The power transistor has 3 wires, ground, (-) coil, and trigger from megasquirt.

    Green is signal from megasquirt, blue is (-), and black is ground

    Good to know. Glad were getting some good thoughts/ inputs on this topic. Im surprised more Z's arent on MS. I am trying to prevent from taking the computer apart and socketing anything at this point. The reason is b/c i have not got the car running yet and i want to elimante all problems that may make the car not start ect. Should get to start it up.....Today!.....at least make an attempt lol

    what firmware do you have?
    Sorry for the late post but will be running MS2E 3.1.1
    But Im still trouble shooting serial comm connection problems. Im using the DIYauto usb adapter, And all the tests (miniterm in tunerstudio/ voltage tests.) are checking out fine, yet im getting timed out error 0xE0… Ill be posting on MSE forums. Need to try another computer I suppose. However Thank you Bloz and black for all the info as I have a 85 ex-automatic and still want to run stock igniter and such. Anyone running the boost controller off FIDL? I have it wired so far.

    It's kind of a bad idea to just copy someone's whole MSQ. What's good is to post VEXs or screen grabs of whatever setting you are needing.

    If you are using the Nissan CTS, it's in the FSM. What are you using for IAT?

    Im also trying to find the AIT Calibrations. Its a Wells SU4978. This ones going to be hard. might be easier to just swap sensor to gm. The reason i used this sensor b/c its short. its a nice sensor to put in line. The AIT sensor is in the IC pipe.

    A RX7 Collent temp sensor will screw into the factor Intake (The reason i used) Here are the calibrations for a Rx7 and Rx8.




    Rx8:The rx-8 Fsm states it's coolant sensor as
    20C(68*f) 2.2k-2.7k
    80C(176*f) 287-239
    91C(196*f) 227-240

    Rx7:
    -20c (-4f) 16.2K = 16200
    20c (68f) 2.5K = 2500
    80c (176f) 0.3K = 300

    I have a GM IAT you can have, if you pay the shipping. I can maybe even just cut the pipe it is on, so you have the bung. It is also a piece of history, came from tmbg's car, the man who started this tread.
    Hmmm, Whats next?

    One wire and i myself feel alot better with a 2 wire. Its Ok, all is well. threw a GM ait in there. Bloz up, Im stuck. Using the stock cas/coil, what ignition settings are you using? under Ignition settings, Ignition settings/wheel decoder i have no clue what to go from. We use optical dizzys and theres no optical dizzy selection? Also the coil blew up. split in 2. was in the car on the lap top and smelled something. Wires werent really hot. coil is F'ed. I think i know why and fixed it. No worries got more coils. All i need is ign settings
