Hondata

I have seen alot of post about the S300 and automatic trans, just nobody giving an exact detail on it. Everybody says it just won't work.

Could someone set the record straight to why it won't work? Does it lose the actual features in an automatic ecu?

Thanks for your time.

The s300 does not contain the code to run an automatic tranmission properly and is not supported by Hondata.

So if we use an external transmission controller we would be fine?

The P28 automatic ECU's lose the code when you chip them?

Automatics are not supported at all by Hondata.

I have a 1995 automatic single cam tuned on s300 thats a daily driver with no issues. We have chipped an automatic p06 car runs great and shifts perfect. I am going to put it on thre dyno and see how much power the car is making because i only street tuned it yet the car pulls pretty good. The car iis runnning 10psi Automatic fun car to drive. I know Hondata doesnt support it and they get all pissy about it but here is some hope!
