2am and MS or car is not working.... so close...
 

It's almost 2am... trying to get miata started after firefighting other build issues..

No spark, no fuel. MS when hooked into laptop shows accurate sensor readings. I've tried AL's map and Akayreyre's map.

Ignitor gets warm, but not 'hot'/untouchable.

Where are the major grounds?

I found two in the IM side harness... they goto motor or chassis?

who built the MS? picture of your mods? I followed the Diy Autotune instructions and the first time around I screwed up the spark mods. Once it was done right, the car started up nicely.

It's a diyautotune build. Works nicely on stim. Only addition is the EBC pieces.

I used a DIYautotune harness and my own obd1 plug...

Did we do the 'Miata Mods' to it as well? (Sure I could look up the order, but not under your board name ;) )

What stim version are you using? If it's 2.1 or 2.1, is it modded with the 200ohm R4?

A 2.1/2.2 Stim with the standard R4 will not trigger a 'Miata Modded' ECU, you shouldn't get a tach signal. You can tell if your stim is modded quickly as R4 will be bigger than the other resistors.

No, I mean it was modded with your mods. Not built by you guys.

Stim v2
With "stim for wheel" I'd get rpm and it would work nicely on the computer....

I wired it up per my "check my harness" thread.
I wired up my Innovate LC-1 into the car side of the harness.
-used 1b for power, and 2A for blue gound, 2C for other 2 smaller grounds
I also ran my GM IAT to the ecu
-1 to sensor location and other to 2C ground

I'm getting no spark and no fuel. Fuel pump primes... car turns over (starter). But no catching at all. When I plug laptop into ECU, it shows sensors reading real data.

Do you see rpm on megatune when youre cranking?
It was very helpful for me to diagnose wrong polarity on my vr sensor wiring. In your case it would tell you if your ignition or cas wiring is correct.
Are your coils wired correctly? if youre getting rpm on megatune and not catching, it could be that your spark plug wires need to be switched. One problem when I was starting mine was I had crossed the ignition coil wires. it was firing the wrong coil which in turn was messing up the ignition firing order. HTH

Like I said, I had that problem as well. I had wired coil a to spark output A and that was somehow backwards for my car.

I'm having the same problem however mine does not read rpm data.

Are you getting a tach reading?

Did you jump d1 ad d2 on te board. Forgetting to jump both those will cause rpm not to read.
