Any way to decode a tune on Aftermarket ECU eprom? Fearless, Mine's, Tomei, etc.
 

Back in the day there were always tons of aftermarket ECU for sr20det, and there was never any way to tell what mods it was tuned for. I'm sure things are different now and there is some way to plug in the eprom chips and read the info? I know that there are file sharing sites and that you can burn your own eprom tunes, but how do you read the tunes? Please let me know any names of software of the name of the device to do it. Thanks.

What i use at work is called Hex workshop 4.2

Thanks for the response. Please tell me more about that software. Is there some device that is connected to the computer for plugging in EPROM to either read or burn them?

So I checked out that software and I'm not a very digital person. How do you get the data from the ecu onto the computer screen and what do you compare it with to determine if original or modified?

Wtf, u bumped a 3yr old thread to reply to yourself/ask yourself a question??

I was asking Krron the question. This site is pretty dead anyways so pretty sure any traffic is good traffic. Why you gotta post non informational responses to questions in threads? If you don't know the info you are not required to respond ya know.

Why you bumping old as threads cluttering up the for fourms.


But hey im glad over the 3 yrs you finally check out that "software" and still dont have an idea wtf ur doing....are we making progress? Probly not, but watchn u bump ur own 3 yr old thread is nice...proceed

Pretty sure it's a valid question due to all the various eprom tunes out there, and rarely is the chip or ecu marked with tune specs, I still haven't found an answer to this question after over 10 years of searching.
Obviously you don't know the answer. So I'm gonna bump my old azz thread every few years and maybe I'll get lucky and someone will be kind enough to post the info.

well go ahead a fuck off for a few years then
