The unit is done thanks to mostly tim, somewhat ben, somewhat yuriy...
It appears to be working, flashed the ECU and MT with the freshest ms2extra beta, crank timing seems to be right since it cranks and sounds healthy but it will not fire. Here are a couple basemaps attached, if anyone can make sense of them. 2.5l motor, about 17.5 pound injectors...

If anyone has ideas, or some steps for me to go through for trouble shooting. Going to check for spark (bitch with my COP, and check fuel at injectors, also bitch). And I wanted to figure out how to use the "output test" option.

Pull a plug and see if it's wet. Check for spark. If you have spark and a dry plug then spray some brake clean or carb clean down the TB and see if it fires. If does without backfiring or bucking then start playing with the required fuel and crank enrichments. If it bucks or does nothing then start playing with your trigger setings.

Yup, I realized I am a tard and I can just pull the coil and put a spare plug in it and check for spark that way. Should I pull a fuel injector and see if it sprays, or just check a plug to see if it's wet? only got <1hour to play with it but ill try to make the most of it.

You should ALWAYS put a timing light on a new install, there are multiple things to check for. Saying "someone else with exactly the same setup used these settings and it worked" doesn't cut it really. It's still a risk if you don't check it yourself with a light.

Things to verify before adding fuel :

Spark is firing at the right angle (on all cylinder pairs if you are wasted spark, and all coils if you are COP.

Things to check after you add fuel and it runs :

Angle remains consistent when you rev it etc.

I would start lean and increase req fuel until it kicks.

MS2Extra doesn't have phase control, so if you are COP pure mode, you might be 360 degrees out for all cylinders. This happened to me when I did my setup (perfectly by the book). But it was exactly reversed. Others have had the same issues...

Good luck

your map is pretty low, could be a bad burn. try re-burning the extra code and re-loading your msq

who knows where to get vb921's for less then the niggeian price of 60$+ shipped on diyauto

send me the part number, i'll see what I can get. Especially if i'm the reason they fried :1

Holsquirt.

------- megasquirt. Still does nothing but turn over and fart, but I have not checked anything throughly due to time constraints besides the f*** TPS. With stock ECU in, I get 4.66 volts between ground and +5v, and a variable of .3-4.3 or something on the signal. Perfect.
Same at the harness.

Plug in the megasquirt = 4.66v at harness on both ends, and AT TPS!! WTF!! I ran the wires straight from the TPS to the megasquirt, same thing. Can't see where on the megasquirt the signal is crossing or something. Gay ----.

Have a couple grounds I need to solder tighter, and go over the board for the nth time.
