Hello,
I have a 1993 10th Anniversary edition Honda Accord. About a week and a half ago my street flooded overnight and water got into the car. The area where the TCU and ECU are located under the passenger side carpet got partially submerged. After letting everything dry out for a week and a half the car starts and runs fine at idle. When driving it runs and shift great until it gets to 3200 rpms. Then it just stays and 3200 rpms and will not go above. When in park and running if you press the accelerator it will climb to 3200 rpms just fine but then acts like its hitting a rev limiter at 3200 rpms. I have two questions. 1. has anyone seen this symptom caused by a bad tcu or ecu? 2. When looking at replacement TCU and ECU they are listed for all other models of 1993 Accords but nothing specific to the 10th-anniversary edition. Anyone know which model of Accord ECU/TCU is compatible with the 10th Anniversary Edition?

Thanks,
Chris

 

Why would it be different because it's the anniversary edition? Does it not have the same engine and transmission?

 

It does have the same engine and transmission but it was confusing because the part number for the replacement ECU was different on two of the same year models that had the same engine and transmission
.

 

 

The previous one was probably superseded. Did you check the Honda site for information

 

This should be the ECU model you need:

37820-PT6-A52

The model you have already should be:

37820-PT6-A52/3 or
37820-PT6-L52

 

Thanks!

 

The ecu is around $20 on EBay. They also have a repair service for the TCU for $90 on eBay.

 

Thanks,

Just ordered one on EBAY. Ill update if it solves the rpm issues.
