I have built a MS-1 V3 per Braineack's instructions. I am all done with construction including idle and fan mods. I have the firmware and MSPNP 95 w/o AFM base map installed.

I am getting no response on the ignition LEDs, nor on the stim. I am a strong believer in free-market economics and fair trade for knowledge and labor. Along these lines I am offering $20 or a perfectly functional BIPES unit to the person who helps me solve this ($20 by paypal - or free shipping if that person chooses the BIPES. If multiple people have the correct answer, the first with the answer gets the prize).

I will upload pics of the front and back of the board as well as the .msq. The only thing I changed from the MSPNP map is the MAP sensor I believe.

I have washed the board in acetone and have looked as closely as I can at the solders. I can't see anything wrong.

I really want to get this working. Ideally - someone will take a look at the pics and say ****ing noob! you forgot to jump XXX and XXX. - that's still worth giving out the money or bipes imo.

Thanks in advance to any help!

 

Take a couple more pics zoomed in and focused on the LED's. I'm guessing you get no RPM signal whatsoever in megatune?

 

Check the resistances on all the transistors that should have insulators. Specifically Q9 and Q12. Those should have nylon screws and insulators, yours have steel screws. Resistance from the base of those to the metal bar should be like 50M ohms or something. It's in the megamanual, like step 63ish IIRC.

 

you have the LEDs installed backwards. that is why they arnt lighting.(i did this too)

you may have the wrong stim is it the JIM stim ? or the regular stim the regular one will not work with the Miatas Ignition mods.(did this too)

The LEDs Are constantly lit for me because the system acts so quick. The middle is for Cold start enrichment.

 

I actually do have tach signal in megatune. In fact, all of the gauges are working correctly.





Last pic is on a 200k scale. Hope these are clear enough.

 

Would backwards LEDs actually kill the spark? I wouldn't think so. I did try to actually put it in the car, and I get no spark at the plugs.

(Coils are still good as car runs fine with factory ECU reinstalled.)

 

Its possibable, i didnt have spark when i had mine backwards but when i fixed mine i went back over all my solder joints too.

I would put them in right and try it again.

 

This is the stim. I don't know what this version is called.

 

I think you have your LED's in backwards. 99% sure, I'm looking for a better pic of how they should be. You should also see 60M ohms, not 60k ohm. Need to fix that for sure.

 

yea that doesnt work with the Miata ignition mods its worthless to you.

I found that out after it wouldnt work for me with the miata ignition mods done.

 

MegaManual troubleshooting guide says 60k ohms. I think this is good.

I am waiting for the soldering iron to heat up to change the LEDs

 

The lower leg on the transistor and the lower end of the resistor look like they need to be cleaned up and resoldered.

 

that is for the Launch control mod, although he should clean it up that is not his problem.

 

Whoops. Yeah, I knew it was Q9 and Q12 and 60 something from memory. Those LED's are your spark outputs. So if they're backwards, you will have no spark. I did the same thing a long time ago and had a tach signal but no spark. Swapped my LED's and it worked.

Also work on your soldering a bit. You want to go fast-hard-short when soldering. Some of the joints on your board are not ideal.

 

WOOOOOT i think i won then hopefully it works for you.

 

See my first post? You know, the one above your first post? Give the guy a chance to see if it works first anyways.

 

right but i said they were wrong off his orginal post, you didnt say you thought they were wrong till after my post clearly saying that they were backwards.

But its w/e.

 

Until he tries to use launch control

 

How bought this. OP keeps his money and helps others when he can as repayment?

 

Also, since no one told him why they can tell the LEDs are backwards - see the little line on the board where the LEDs go? That symbol means you put the flat side of the diode on that side (can't remember if it is the anode or cathode, it has been 12 years since my last electronics class).
