Title: Am I on the right track? Post by: lewisisonfire on April 22, 2013, 02:01:06 PM So I've been on here a few days collecting together the information available and I inevitably have a question.
Call it more of a query to check my progress of learning. Am I right in saying that if I found a tuned map file for ECU xxx-xxx-xxx-J and I have orig: xxx-xxx-xxx-CG, I could run both these files through a hex editor and compare the two. When I locate strings of code that match mine these are the parts that can be adapted to tune my original file? (Assuming these matching strings are the tuned parts) Would I essentially be building myself a map for my ECU? Im not look for the answer if im wrong, more of just a "your wrong" response and I can keep searching. I just need to know if im on the wrong/right track. A lot of the language used to describe each element of tuning is still not 100% familiar and its taking time. I think im right in saying after completion of this task a checksum would need to be done to confirm the map is ok. Title: Re: Am I on the right track?

You also will never learn the ecu that way, because again you don't know why the modified values are what they are. You don't know if it's the right way, or for a custom setup, or for a setup with a problem that has been "tuned around" Start from a stock file and make the changes yourself.

Tuned A vs Stock B is pointless Compare Stock A to Stock B, or Stock A to Tuned A, etc. Title: Re: Am I on the right track? Post by: NOTORIOUS VR on April 22, 2013, 02:29:24 PM I read it as a simple revision change
Title: Re: Am I on the right track? Post by: nyet on April 22, 2013, 02:30:50 PM Without knowing what -J and -CG are referring to, i assume they are different software versions of the same *stock* ecu?
Title: Re: Am I on the right track? Post by: lewisisonfire on April 22, 2013, 02:50:33 PM Ok thanks for the responses guys. It was an educated guess after a post I read through. I thought it seemed a little to easy.
Theres a lot of technical language to try and get through. from damos to maps, hex files, xdf's. I wont give up though. |
