After relentless testing and research, we are proud to announce our new socketed/chipped OBD1 ECU for vehicles with automatic transmissions. This is the tuning solution you've been waiting for if you have an automatic transmission Honda or Acura with a B, F, or H series engine and are tired of being told you don't have a tuning option.


This ECU package is available with Bluetooth option. The Bluetooth option will add our CN2 Bluetooth module and enable datalogging within the chip's programming. This will allow you to wirelessly datalog from a Bluetooth connected Android smartphone or tablet with the TunerView app available in the Google Play store.

IMPORTANT - This ECU MUST be used with a separate automatic transmission control unit (TCU/TCM). This ECU is designed to allow full communication between the chipped OBD1 ECU and the TCU, resulting in a great solution for those wanting to run a chipped ECU in their automatic transmission vehicle.

Will NOT work on vehicles with a D series auto transmission. Only compatible with B,F,H series auto transmissions. You must use a separate transmission control unit that is compatible with your specific transmission.

This ECU is developed to be used with the CROME software for OBD1 Honda / Acura applications.

This ECU comes with a FREE custom programmed basemap chip to get you up and running. You will then need to have the ECU tuned to run best on your vehicle by a tuner who offers tuning with the Crome software. Your tuner MUST use a chip in this ECU that is programmed using the P72 basecode. It will NOT work properly if any other basecode is used on the chip. Your tuner can start the Crome software with a P72 basecode and modify/tune from there to suit your engine setup. We program the custom basemap chip with the P72 basecode for you before shipping. Your tuner can simply read the chip that is in your ECU, then fine tune the basemap from there.

    On OBD1 vehicles that have a separate TCU from the factory, this ECU can be plugged right in:

  • 90-93 Honda Accord with automatic transmission
  • 90-93 Acura Integra with automatic transmission
  • 94-95 Acura Integra with automatic transmission
