Where is this product assembled?

  • This product is assembled in Suwanee, Georgia, USA

Will this plug into my 4AGZE swap in my AE86?

  • The 4AGZE engine harness uses a different connector and will not plug in.

Is this all that I need to get started tuning my 4AGE?

  • The only other potential must-have is that if your laptop doesn't have a 9 pin serial port, you will need our USB to serial adapter to connect to this unit. However, there are several other things you may wish to add to use this unit to its full potential.

What about the JDM 4AGE that used a MAP sensor?

  • Not only is the ECU pinout different, but these cars also used a different ignition system. Putting this MSPNP on one of those engines would require both repinning the harness and swapping to the USDM ignition module.

What about 20V swaps?

  • If you are using the 20V motor with the 16V wiring harness and ignition, this could work. It will not plug into a 20V harness. The '96-'00 "Blacktop" wiring harness is very similar to the harness our '93-'95 3S-GTE plug and play works with, but we have not been able to test this application in house.
