Default MSPNP PR0 need help wiring it o_O

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?

MegaSquirtPNP by DIYAutoTune.com


although after reading through this, it's still completely unclear which pin on the rear connector is actually used for wbo2 in...

I think 18psi had this same problem...surprised they haven't updated the documentation since.

Just a minor oversight and we'll get it fixed now that you have brought it to our attention.
one hell of a long time to update them...


but the answer is:

Update - you may use any of the extra analog inputs; just change the O2 input port in the software. This was done so you don't have to unplug any of the stock O2s.

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.

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

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.

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