Thanks mate, done, but tunerstudio find a signature firmware mismatch, and ask me if I want to update ini or connect anyway...

"Project sign 3.0.3h
Controller sign 3.0.3s
Isn't raccomended to connect etc. etc."

Shall I connect anyway? I can upload 2090912 firnware in the ECU if this is the correct procedure.

sounds like you still didn't source the correct firmware locally.

try this one
ms2extra_alpha_303s_20100329.zip

No, there wasn't the correct firmware loaded into the ecu.
Now I have loaded the 3.0.3h, and the base map works.

But the car want start. Not a sign or a "pop", nothing.
I have spark and also fuel (a lot of fuel smell after some starting attempt).
The base map http://www.diyautotune.com/diypnp/ap...00-18bp-mt.zip is for a Jackson supercharger and 330 injectors, and this is a NA car with stock injectors, but no sign of life is strange.
I have tried the base map with from 33ms to 20ms cranking. I have tried to invert coils. Nothing changes.

Any luck getting the car to start? I have a 1999 and the same DIYPNP. I just finished the jumpers last night and I will load the firmware on today. If you find a map that works could you post it?

Today I have the chance to retest the ecu on the car.
I don't know why but something changed from the last time I try the ecu on the car : after the first two startup tests the ecu show me a config error (with rpm to 65535 and no fuel pump). I have reloaded the base map a lot of times but tunerstudio show me 8 warnings that before than it never showed me. Anyway, I have redownloaded the base map from diyautotune and then into the ecu, only 5 warnings and no config error!!!!

OOOOKKK....rescaled and tweaked the reqfuel for OEM injectors instead of the 330cc of the base map, and the car start!!!!!
I have low idle, no idle control (IACstep is a fixed value of 97), and as soon as i touch the throttle the engine die. Also O2, oem narrowband sensor, is a fixed value of 0.170!

Maybe a stupid question : When I open the project I have to point the ms2extra or us2extra firmware?

Mate, have you tried nothing?
I had success getting the car start, but it has only a good idle, nothing else...
Batch inj, MAP multiply OFF, req fuel 15ms, massive start enrichment and leaned VE map at idle.

How have you solved the alternator voltage regulator problem?

I used a diagram off this website, here is the link: https://www.miataturbo.net/showthrea...ht=1999+diypnp
I purchased all the components from mouser, and have all the part numbers so PM me if you would like them. Alternatively; I ordered enough to do 3 alternator circuits in case I messed up, but I got it on the first try, so I can send you the components or wire it up on a spare circuit board i have and mail it to you so you will just have to connect three wires. (just pay shipping and parts, I will put it together for free!) PM for the built circuit as well.

I was able to get my car running pretty well, but I didn't have a wideband O2 sensor at the time, so it could use some tweaking. If you would like me to send you the map I would be more than happy to. PM for the maps and settings.

Thanks, my main problem is that I haven't found the 48.7K resistor and other precision components, so the alternator circuit doesn't work, and I can only do few minutes of tuning on battery.
I'll send you a PM ;-)
