FYI: WinBin 1.4 checksum issue

[tminer]

I have been using WinBin 1.4 and it's 148.ecu file just to do checksums. The ecu file needs to have the checkSumStartAddr parm set to 2 (I think that it was set to 4). Since locations x2 & x3 are normally 0 it worked fine until I tried to checksum chips with fast update code patches that change location x2. Unfortunately, the only error indicator was the rapidly flashing SES lamp (and probably a Malf code).

Tom, why use 1.4 instead of 1.6, the latest version? Second, who's ecu file are you using? The one I put up at the gmecm web site, or someone else's (I want to make sure mine is okay; it sure works for me)?

 

[tminer]

It was in the CAB. I don't remember where I got it (author's site?) and the 148.ecu is very incomplete. I only use it for checksum (not much else works for the 148 anyway).

Tom, first, I'm sorry, 0.0.14 is the latest WinBin, not .16 - senior moment . Second, looks like www.diy-efi.org is down just now so since you can't get to the gmecm ftp site I put my .ecu file up here: http://members.verizon.net/~carl.ijames/cfi7148stock.ecu.txt You need to trim the .txt extension after you save the text (I didn't want to figure out how to make it ftpable and this works ). This has most of the needed stuff for tuning, some extraneous stuff you won't need, is missing a few things that need to be added, has maybe 1/3 of the eprom data locations defined, and no errors that I'm aware of. Third, Eric doesn't seem to be developing WinBin anymore but Mark Mansour is working on a new program GMECM Edit which is already more capable than WinBin. Get it at www.markmansour.com Enjoy (or ignore ).

Good info and thanks. I just use HexEdit 2.0, which is a generic hex based editor, but others may benefit. Yea, I'm a programmer trying to learn to tune. I sometimes feel sorry for my poor motor .

Carl, thanks for the tip. Like Tom, I'm used to the Hex Editor and don't normally "think ouside the box".

A better link to use to get to Mark's editor is:

Shucks, I think I'm gonna give this new fangled, graphed up windows thing a try. Wish me luck.
