'00 1.8 european Miata - MS2 assembly
 

This is my report of an MS2 assembly.
I have bought also the SEQMOD module for full sequential injection.

I have all I need to start

Partially done

Mainboard done, except the voltage regulator in the proto area that is work in progress. I cannot find 3K, 30K and 48.7K 1% :mad: I have found 2.7 and 3.3K, 33K and 47K.

Is this the correct position fot the SEQMOD?

This is what is left unmounted and I know that it's needed :
-position and shunt jumpers
-wire
-screws for case
-D-sub connector Hood


This is what is left of the kit, unmounted, and I want to be sure that is not needed, give me your opinion :
-1 extra diode
-some 100ohm pullups resistors
-5 1K pullups resistors
-1 optional R20 51K resistor
-3 4670ohm pullups resistors
-optional R39 variable resistor
-Mica for Q17 (I really don't know what it is)
-some washers

It is. And the mica goes under the high side driver.

Our idea here was it was better to supply too many parts than not enough.

I noticed the MICA in the last few kits I purchased that recieved the v1.5b. What's the through behind it? I didn't think the pads were grounded.

Probably the flyback diode for the idle valve. It's required if you're using the idle valve.

The pads aren't grounded. There's a via right there; the mica is just a precaution.

Thanks guys.
I have a question : is the european pinout = to the USDM pinout? Reverant pointed me on the fuel pump pin, but he doesn't remember exactly where it must go. And what about other pins?

Other pins are fine. I've built a few units for european cars, fully equiped with A/C etc, and none had any problems.

Thanks a lot. Where the fuel pump pins is on EUDM cars? I only have this diagram, but it's from an USDM manual

3R or 3P.

I have finished now to make all the "edge pin connection" except fuel pump. I am a bit confused about "Pull Ups" and "I/O circuits", maybe I'm only very tired.
Can someone explain these simple?

fuel pump is 3P on euro cars.

Thanks, connected.
I need help to find PA0 on mainboard to activate relay1 for radiator FAN.
Ins't it pin 1 from J1 that goes direct to the processor?

It's in the spare I/O header in the top/middle of the board.

Found and connected.
Now I'm loading the firmware.
The base map that I have downloaded use MS2/Extra 3.0.3 - 20090912, I must install these FW (that I can not find) or the 3.0.3 20100522 is ok?
I'm Trying with 20100522...finger crossed :-)

Firmware flashed.
Now when I try to open the MSQ tunerstudio give me this error : <<cannot find the controller definition file (ini,ecu) for signature:MS2 Extra Rel 3.0.3h>> and ask me to select the appropriate configuration file.

What's wrong?

Really can't find the 20090912 firmware in MSextra forum...is this the problem?

why arent you using 3.1.1?

I have used the last firmware included in the package of DIYPNP website.
But the base map for this specific application is based on an old firmware, that I cannot find

http://www.diyautotune.com/diypnp/ap...0-18bp-mt.html

Is this the reason for the strange error that tunerstudio give me?

so go to project properties and point it to the directly of that particular firmware .ini file.

3.0.3 20090912 FOUND!!!
http://www.msextra.com/doc/ms2extra/files/alpha/
In the ecu now I have 3.0.3s...I have to upload the 20090912 into the ecu?

just d/l the files and point TS to it.

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.

One of the attempt logged

Someone can give me the injector charateristic (including ReqFuel) of STOCK fuel injectors of a '00 1.8L Miata?

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!

Attached the warnings, and a datalog of some startings of the car

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 ;-)
