Hi Community,

I want to build a 05 vvt Miata turbo. I bought a MSPNP PRO used from ebay.com and downloaded the Manual. I was searching for a Pinout diagramm but sadly i have not found it for the MSPNP PRO :(. The manual only got the rear option connector description in it. I want to know where to wire the Spartan2 and the IAT-Sensor i bought. I am new to MS and hope for your help.
Beside this: I tested the MS with everything else standard: I noticed that the engine starts very late and is reving high and dies when i try to accelerate. The engine run for just 30 sec. is this behavior normal?

The PnP is specific to individual model years. What year ECU do you have?

 

I have got the MS PNP pro 01-05

 

 

Here's the main connector pinout.

 

Is it okay to ground both the IAT and the WidebandSensor to the pin: sensor ground?

 

If the wideband has a separate analog ground, yes.

If it has only one ground wire on the control unit, no.

 

it has two seperate grounds. one 4 the heater (i will ground that one to chassis), and one for the sensor (which id like to mount to ms pin sensor ground)

 

bad news.... cel keeps flashing and no connection to my laptop :(

 

Try reloading the firmware using the boot jumper. If you get an error message, post a screen shot.

 

Do you want to scan your serial ports automatically? (y/n default y)

WARNING!!!
No valid ports or ECUs found. Cannot load firmware without communications.

Common problems:

- Something is hogging the serial port.
e.g. TunerStudio, modem or mobile phone cable software.
Be sure to close/exit those applications.

- USB-serial cable on high COM port number, use Device Manager to re-assign
it to say COM1.

- ECU not powered up, be sure there is fused power applied. Use a mains
adapter or vehicle battery. PP9 batteries are too feeble.

- Serial cable not connected correctly

- Software driver problems

Check the above. Do you want to try probing again? (y/n default = y)

What cable are you using? Does it use an FTDI chip? If so, do you have FTDI drivers? Have you ensured the MS is getting a full 12V? Have you checked device manager to make sure the USB cable is being recognized and is assigned a COM port?

This is usually my thought process when I can't connect.

 

i havent changed anything, it worked just fine... then started the car and connection broke.... now it claims no connection.... cel is blinking like hell and car wont start...:((

 

Do you have the first two power LEDs on the MSPNP on steady with the key on?

 

light 1,2 and 4 are on steady, 3 is pulsing very low

 

Please Help me

 

OK. Try reloading the firmware using the boot jumper on the MS3Pro Module. If you get an error message, please post a screen shot.

 

Thanks mate!

 

car starts and runs, but charging voltage is at 18,7 Volts! Please Help mee^^

 

Im software there should be an option to program the voltage regulation afaik.
