After about a year of trying to figure out the problem with this car, I finally got it thoroughly scanned and received a P1779 code, an Engine Torque Input Malfunction. I was told that I would have to take my car back to the dealership in order to get the ECU reprogrammed and updated. Do I have to go to a dealership or can I go to a service shop? How much will this cost?
How much will it cost to get an ECU software update? on 2005 Suzuki Forenza

approx 125.00 but varies in diff areas. is it a wanrranty issue?
No, it's not the warranty. My car has been riding rough and misfiring badly for a while. For the longest, whenever I got it scanned, it would return a P0300 code. I've had it tuned and even replaced the catalytic converter but nothing helped. I got it scanned by a G-scan (I think that's what it's called) when it gave the P1779 code, and this was the only code that came up. I called a dealership and they told me they would charge $97 for the update.
good price but make sure it will fix your problem
I'm hoping it will. I spoke with my mechanic and did a lot of research on this. It makes sense to believe that it's the ECU. I just hope the update won't cause additional problems.
I'm having the same issue with mine. How did your car turnout after the update?
