Cant get MS2 running, please help
 

Ive been trying for a few weeks to get my car(91 miata with 1.6 and flyin miata turbo) running and have had no success. The car ran a few months ago when i first installed it then a few days later it would not run. Since then ive been trying to figure out what was wrong with it.

Now a few days ago my hard drive crashed on my computer and i lost all my files and when i tied loading the original settings for the miata on tunerstudio and connected I get an error message and it will not spark. I can post the error its showing but i dont know how to fix it.

Is there anyone who can send me the settings for everything on their setup that is similar to mine so i can get this thing running or anyone who i can send my megasquirt to who could sort out my issues?

Im not that goo with electronics and i simply wanted something simple to operate but this is killing me and it is getting way more involved than i wanted to get.

Would you guys recommend that I just sell this MS2(it came with the turbo kit) and buy a MSPNP2? Im not looking to learn how to get too in depth with tuning(i dont want to have over 200hp as i will be autoX the car) and I also just want something reliable as it is my DD too

Ok, I'm going to be nice and reply and try not to be too much of an a-hole:

1. The MS2 and MSPNP2 use the same software, so it doesn't matter which one you use, you will have the same issue.
2. A simple search will bring up a base MAP from DIYAutotune (and 100 others) as far as a baseline.
3. Posting an error msg or the MSQ files would help.
4. If you get an error message, most likely it won't spark.
5. We need to know what your issue is first before sending you anything. This has nothing to do with electronics, it's all software setting. You might want to read up on MegaSquirt and how to tune generally before you attempt to start the car and blow up your house! The radioactive core in the engine might overheat and bad things will happen!!! BE WARNED!

Ok, thanks for the reply.

I knew that they used the same software but i figured maybe the PNP setup may be easier as there is less wiring i would have to deal with.

I have done alot of research on megasquirt before i even thought about putting it in, i just dont learn well from reading. I just graduated from MECHANICAL engineering so im good with numbers and hands on(mechanical work such as engine building, carb tuning, head porting,etc) so this whole standalone setup is a scare for me as ive always had trouble with vehicle electronics and computers

One of the reasons im trouble i think is that i went through a tutorial to get some stuff sorted properly and may have made a few changes that could be casusing some problems and that is what im looking for mostly is the other settings such as ignition, injector parameters, etc.

Ill try and get that error message up here in a few minutes. I wish i had someone local because i dont learn this stuff well by reading, i learn by hands on or someone teaching me

Ok here are the 3 screen shots of the errors im getting

BTW whenever im on Mini Terminal to view the error, tuner studio freezes and i have to shut it down with task manager, idk if that is relevant.

That is actually what happened then my hard drive crashed when that happened before and i lost everything on my computer, they may not be related but thats what happened

You tried to use D14 or D16 as a programmable output, which is not right as these are your spark outputs.

OK, so how do i fix that? is that programming or is that hardware? I dont recall ever messing with that

Under "Basic Setup" should be a input/output section I believe if the menu on Alpha 3.3 is the same should be called "Feature list showing I/O pins"

Sorry, i dont see that anywhere, maybe the menus are a bit different or im just blind lol

ok so i did some more searching and these are the only two things i found that seem to be in the right type of changes, but none of them made a difference. When i tied to change the outputs for ignition it just gave me an error that said that the Tachometer outputs were wrong

See how in the first picture the PM4 is green, go and see why that is. That's one of the ignition outputs. When you click on it, it shouldn't be enabled.

Ok, so i disabled that port, it was setup as a warning for for the coolant temperature, idk why.
Anyway, the error went away but the car still wont start. It spins over fine and has spark but does not sound like it even wants to run. What would be the next thing to help diagnose the issue? Should i run a datalog while trying to crank?

Can you post your MSQ file please

here it is

Well looks like your spark output is on JS10 and not D14. Do you have an old msq file you can load on this thing?

I installed a msq file that was a base for the miata so now I'm getting better results. The only thing is that it does not want to stay running. It only runs for a few seconds then dies. I'll get an update if I can't figure it out

Here is my current MSQ file and a data log when i was trying to get it running. If you guys see anything that needs to be corrected please let me know. Thanks

Do you know what injectors are in the car?
And does the car have a wideband oxygen sensor?

stock 230cc injectors(future plans i have 550cc)
innovate LC-2 wideband

That appears to be a ignition log and not a datalog. And that MSQ you attached has the JS10 as the ignition. Really hard to help without knowing if D10 or JS10 are used for primary ignition. Back to the beginning... this MS2, was it used with the turbo kit or did it come with a kit you bought (BEGI?)

As far as i know it was unused. The turbo was used but the MS2 was supposedly new, he said it was modified by Reverent, he sent me this thread about it https://www.miataturbo.net/group-buy...90-05-a-60486/

I'm not 100% sure on the details but this is what he told me

Have you tried PMing Reverent? If it was indeed done by him, he is really helpful and knows the mods inside and good probably give you a base map that would work.

Spark A output MUST be D14 for Miata ignition. MUST MUST MUST

Ok, well i changed it to D14, it still is doing the exact same thing.

Ill PM Reverent, but i didnt realize it was him until i posted the link.

There you go!

You will most likely have to play around with ASE to keep it running. Can you make it stay running by giving it a little bit of throttle?

Is the fuel pump still running after the car starts? I am assuming you have removed the AFM, right?

Ill try messing with the ASE. The car will not idle and playing with the throttle makes no difference in keeping it running, always dies after 2-3 seconds when it does light off. As far as i can tell the pump is still running when it dies, but im going to be upgrading the fuel lines and pump this week sometime(i have all the parts in, Walbro 190HP and AN fittings and fuel line)

The reason I am saying that is because the fuel pump is controlled by MS2, however there is a certain changes needed to the car to make the fuel pump still run after the car starts. I don't have a Miata, and have only put DIYPNP on Miatas, so not going to hand feed that one to you.

You seriously need to do some search and read more about this. You can't just put it in and expect someone on internet to draw every single step of it for you. Perhaps someone can enlighten you about the fuel pump and what you need to do. I know with the DIYPNP you need to remove the ST fuse. But not sure what Reverent does internally and what you require. Changing your fuel lines and pump doesn't help if there is no power going to it.

I understand that replacing the fuel pump wont fix an issue with the megasquirt but it does eliminate the possibility of the pump having issues( i dont know how old the pump is), also if this megasquirt gets to annoying ill just go the FMU route, which i dont like but i have everything for it.

It may be hard to believe this but i have spent well over 100hrs in the past few months trying to figure this out by doing research and reading tutorials, etc. Its like i said in my first post, im not good with electronics and only learn really by someone showing me what to do. I bought this megasquirt because all the stuff i read before about it made it sound like it was almost just plug-n-play, set ignition and it starts up and you start tuning, but now i know that is not the case.

I'm also the type that I dont ask for help until i am literaly about to smash what im working on. Ive been trying to get this fixed but 2 or 3 months apparently is all i can take.

Also its not that i dont know how to tune, for my senior design project we modified a water brake dyno and built a custom intake and exhaust for an engine to into a FSAE car

Any luck skywalker? i am in the same boat haha

No, i decided to go a different route for the time being. Im running a begi fmu, supra 305cc injectors, and staying at 5psi for now. I only want to autocross the car and 5psi is all i really need i found out this weekend.

I will be getting another miata soon that i will try and get everything to work on first before i try megasquirt on my DD again
