Where is this product assembled?

This product is assembled in Gainesville, Georgia, USA.

I have swapped a different year engine; will this still work?

You must use the MSPNP that matches the year of the engine harness you are using. It can run later engines, such as the M52 or S52, if they are using the ’93-’95 wiring harness and sensors.

Is this all that I need to get started tuning my BMW?

This is a complete package. But there are some accessories you may want to use to get the most out of this unit.
- If you are tuning it yourself, a wideband O2 sensor system is a must have for adjusting the fuel.
- This unit can function as a boost controller if you add our boost control solenoid package.
- This ECU has an RS232 connector. You can use our external USB adapter if you need to connect over USB.

What about OBD2 equipped E36s?

This unit can work with later E36s that are swapped over to the ’93-’95 wiring and sensors.

My e36 has a 413 ECU and a stock M50 engine. Im swapping a S50B32 EVO engine, it has 2 VANOS. Can this ECU control them individually? I read the MSPro does up to 4 VANOS controll but I cant be sure about this plug in unit. Thanks!

Asked by Nathan Alves

A
The MS3Pro PNP can run multiple VANOS outputs. The main obstacle is that there aren't any wires for the dual VANOS in the factory pinout. It will need some wiring changes (using the options port on the back of the ECU) and if this engine uses the four solenoids for VANOS, you'll need our HSD-4 high side driver module to control the solenoids.

A
The software has a Portuguese translation setting, although I can't vouch for the accuracy of the wording. Official documentation is currently only in English.

You can connect the LC-2 to either the factory narrow band signal wire or to the O2 input on the expansion connector at the back of this ECU.

Asked by ed

A
Unfortunately, the 402 pinout is a bit different from the 413. You could potentially repin the 88 pin connector. We're looking into making a 402 version as well, but we wanted to get the 413 version out first as it fit a wider range of applications.

Would this work in an E30 that's been swapped with one of these motors? Are there certain things that wouldn't be function or would need to be wired?

Asked by Chris Sladek

A
As long as you are using a "413" series ECU as part of the swap, yes. The only things that would not be functional would be smog equipment type stuff as this is a race-only ECU and not intended for street use.

Is a wideband required if I'm not self tuning?

Asked by Chris Sladek

A
No - you can run on a narrow band once you have the tune set up for what your engine needs. The wideband O2 sensor is optional.

Asked by terrence mayers

A
Probably not - this one replaces the Bosch "413" controllers, but I expect this one would use a Siemens ECU with a different pinout.
