993 Guy

I just removed and inspected my ECU after driving another 993TT and realizing that my car is not nearly as linear and compliant as the other one I drove.

As I suspected, my ECU was reprogrammed in 1998 (as per the writing on the backside with the word "reprogrammed" and the date in 3/98 when it was done).

I'd like to get my ECU back to stock or a program that is better suited to the setup of the car in its current form. I stopped by my local Pcar dealer this morning as I have some friends there and they can't reprogram it (which I suspected but wanted to confirm as it's a 97 and not a 96 ECU).

Would like to avoid spending a small fortune on a new ECU as well...

Any and all thoughts/suggestions on this topic are greatly appreciated.

Thanks!

I have a stock 96 ECU that should work in your car. Not looking to get big money for it.

What's programmed on it now?

993 Guy

I don't know...that is the issue.

It pulls like a locomotive, but you can certainly tell that it's been reprogrammed.

Is there a way to find out what is on there?

There are not a lot of guys reprogramming 993 ECU's. I would send it off to Protomotive and have Todd take a look. I am sure he can also re-flash it back to stock. In my opinion you should try and have a good program installed that delivers power and smoothness.

Agreed...I'm going to head to Protosport here by me to have them take a look and make an assessment given what I have.

Thanks.

The car's prior owner, before me had it taken care of by Mark in Formula motorsports in NYC. When i had the car the ecu was not touched. It might be worth a call out to Mark. Hope that may help, thanks Bob

Thanks Bob...I'll reach out to Formula to see if they know who programmed it and with what software.

Looks like it was done in 1998 so it may be tough to go back that far...
