NSX Electronic Computer Unit – Manual Transmission Conversion




Converting your Automatic transmission NSX to Manual? You’ll need to either change the ECU or convert your AT ECU to operate like factory.

Our process is simple. We have one of our NSX technicians to inspect the ECU for faults to start the conversion process.

We also remove the factory speed limiter with this service.

The conversion process takes approximately 7 business days for completion. This timeline can vary depending on each ECU condition.

Please take a check the conditions needed to have your ECU serviced for the manual rewrite conversion.

Conditions for ECU to be successfully converted;

-ECU must be from an NA1 car (OBDI)

– ECU must be in good working order prior to conversion.

Please understand that not all ECU units can be converted. If this is the case, we will send you an email notifying you about the situation.
