Default Megasquirt and EBC, I hate it

I hate Megasquirt. It is the source of never ending sorrow for me.

So I have an entirely new setup on the car and everything is going good. I decided to finally install my EBC. Everything is wired and plumbed up correctly. So first issue. I don't know which Port it I need to set it too. So everytime I turn boost control on I get a system error message. Doing some googling I find a thread on this

https://www.miataturbo.net/megasquir...n-error-62986/

I disable PA0. Power cycle and no error. "Thank Jesus" I think, but this is where it really gets fun. So after a couple seconds it generates a difference report. For some reason the controller settings are all FUBAR'd. So I hit, "use tuner studio settings" then it starts flashing some error about something being messed up. I try to cancel the upload but its no good. Then it gets better, go to start the car, fires once then quits. I reload an old tune, same thing. Now I'm really pissed I go to the oldest restore point I have (Just two days ago) No dice. Fires up then quits immediately.

So I'm rather upset right now and about to use my chopsaw on this thing unless I can get some help. Last time I had issues this bad my ignition system ended up frying itself so I'd like to avoid that if at all possible.

Attached is a copy of the tune I'm trying to work with.

Any help would be greatly appreciated.

Quick update. Now turning the boost control on no longer gives me an error message no matter what I do. Still wont start though, fires up then dies.

Why do you do this to yourself? I gave my advice, which was, if running ms2, don't even mess with EBC. Keep your **** simple and you should have less failure.

It shouldn't be this hard though. And it definitely shouldn't have screwed me this bad.

Here's some more interesting information. I noticed the fuel load with just the key on was 50% not 99% as it should be. I was able to track down an old tune from awhile ago. Loaded that and its back to 99% but still wont stay running.

It will stay running slightly longer this morning. If I crank the ASE way up it'll idle for a couple seconds.

Here's a composite log of trying to start this morning.

Is your fuel pump staying energized? What's the fuel pressure doing?

I believe so. I don't have a fuel pressure gauge but the fuel load stays up at 99% then when it fires up slow drops down. Its like everything just shuts off after it fires up. Playing with the throttle does nothing.

Yeah so I updated the firmware that made it worse. Still doesn't start and as a bonus rpm's aren't synched to the megasquirt anymore.

Is this one of my old units based on the DIYPNP? Did you flash the code for the MS2 or for the Microsquirt Module?

Yes, flashed for microsquirt module. Finally got it start. Rpm's synced. Stayed running only if I kept the rpm's above 1000. Letting off the gas makes it die.

bonus problems galore. Starts and sort of runs. If I use the throttle to get it running it will run at like 500 rpm. Not sure if its not getting spark or not. I will have a datalog in a second.

Datalog. I think maybe some settings got lost in translation or something. Also included current tune.

Ok so I can get it to idle (sort of) and I drove it around and it feels fine aside from the fact that my fuel map is apparently fubar'd and what not. I checked my idle control settings and it says none. Can't remember what it was before. Idk it definitely doesn't sound right at idle but at least it "sort of" runs. Can I throw money at someone and make this go away?

Today sucked serious horse clocks but I think I'm all better now. Rev kindly fixed my issues and told me my serial to usb cable was broke. So I got a new one. No more issues. About to go test out the ebc. Also after I jiggled some wires I was able to get the car started again so I took out the last few vamp taps I had left. Hopefully no more issues.
