Ms3 MS3x on a MSM
Anyone got a basemap for a msm? Car is basically stock with a set of supra 305s, and ebay downpipe. I've about got the ms3 ready, hoping to get everything tested and maybe a rough tune tomorrow.
I keep forgetting to order parts for the alternator control circuit... so we're going to be a bit limited, hoping to get it roughly ready off the battery, then build the alt circuit this week and give the ECU back to them in time for the Autocross next weekend.... Probably a bit ambitious, but if everything goes well why not try?
I've roughly followed Frank Devocht's guide, which is obviously setup for a VVT NB, and I'm wondering what people do for EBC control. We've got a GM EBC, was hoping to splice into the factory EBC wires but it looks like the ECU switches 12v instead of ground. bastards. Does everyone just run new wires for it?
Also VTCS... Does it default to open or closed? I.e. do I need to worry about controling it for now?

Fun note: 04s (at least) aren't wired for power like the 01s are... Frank's instructions don't mention at all that you have to turn the Main Relay on for these later cars... 4s is key switch on power, 4AF is in fact a red/white that doesn't have power till you ground 3h to turn the main relay on.
Wish I had had the factory ecu diagram when I built the harness, as is I looked like a fool until I traced where the black/white (key-on 12v) source actually made it to the ecu.

So... whats the preferred way to flip the main relay on? I'm thinking i'll just use a spare pin on the ms3x to say if coolant > -120 or something and just have it always on... I would try the Fuel pump driver, but don't want to burn it out... Actually, you'd never get crank/cam signal to bring up the rpm to trigger the FP relay if the cam and crank signals don't have their 12v turned on....

you can just default the output to being on normally. don teven think you need any conditioners.
so active, the like 1 | 0 for the settings.
most would be 0 | 1 and then a condition to turn on.
