Well I've been working away, and now I realize I've made a balls-up. I bought the MTX tunerpro plugin when I read my original file, and the license is only good for that file or its variants. I can't actually correct the checksums on the 518AK file once I've modified it! I went with the 518ak file because it was hard to find a decent xdf for my original.

I tried me7sum, but it failed. Now I'm faced with the choice of starting over with my original file, or buy the "commercial" license from MTX..... Angry

Please post your bin.

The latest version of me7sum should work.

Strangely enough, I have an "alternate" choice xdf and bin for 8e0909518ak that i can correct with my MTX plugin, and will run on my car. I chose to use the .bin/xdf in the original post because it came recommended to me. Not sure where to go with this, If I use the "alternate" 518ak xdf, it will need some streamlining. Too many maps for stage 1 and a little confusing for newbs Embarrassed. Here's the "alternate" files, I found them here on Nef...

I've had issues with this file.  I couldn't get LAMFA fueling to work on it.  Now I am instead using the file originally posted in this thread instead.  Waiting on logs from this file, so I can't yet confirm that this one works any better, though it should.

I have the same RSA signature error on both of these 518AK files when using the MTX tuner pro plugin.  I'd be weary of flashing these MTX checksumed files to your car if I were you.

ME7Sum now works with this file, and other ME7.5 files.  BIG Ups Nyet!

Hey all, turns out I must have mixed up my reference file for the MTX plugin or some other housekeeping error in my bin file directory. I've since cleaned things up and MTX is working for the community project file again!


I'm going to attach the modified stage 1 file* for nyet to check for compatibility with me7sum etc. (all I've changed are the LAMFA values and axes, and a new ldrxn curve).

I HAVE NOT TESTED THIS FILE!! FLASH AT OWN RISK

Here's a screen shot of me7check giving the OK on the corrected file as well.
*I have removed this .bin file because it had RSA errors*


I'm going to re-do my stock file logs (what parameters to log?) and then flash over this one and log again, probably tomorrow.

For the sake of the community project, I would suggest that you use ME7Sum.  Setup tunerpro so that it you can set a keyboard shortcut to correct or validate checksums with me7sum.

This is free to everyone and everyone can get it now.  MTX costs money, hasn't even worked for me, and it takes time to get the license file from them.

If you check my past posts I have showed how to setup me7sum for keyboard shortcuts.

Also the MTX plugin, we're you trying with the ME7 plugin? Or the ME7 2002+? I was referring to the use of the 2002+ one for my friends 518AK file. I haven't made a file yet for him cause he didn't wanna buy plugin. But now that's I have enough of a xdf to work off of I'll give it a try.

Also, have you posted the v2 xdf from the above screenshot? I'd like the one with psi vs. Load it just makes more sense to me.

Thanks

I'm going to look into using me7sum exclusively, for ease of use in this project. I've also removed the .bin file I posted earlier that had errors.

Here's the v2 xdf I"m using

I'd like to incorporate the "pushbutton" emission and cat delete niceties from the 2.7 thread. How is this done? Ddillenger secret?

Copy the parameters from my xdf, paste them into yours, change the addresss.

If you check my past posts I have showed how to setup me7sum for keyboard shortcuts.

AudiMan85 - Thanks for this. I've got the shortcuts up and running in Tunerpro. Very slick, and so easy. Is it possible to output the file as the same name instead of "fixed.bin"?

I flashed the file to my car today and went for a 10 minute city/highway drive. Feels pretty good. Real car-running proof that me7sum does work for me7.5! I'm going to log when the weather is better. Is there a standard list of log parameters for something like this? I want to have all the info available.

From an educational standpoint, I'd like to ask someone to please explain the changes we've made in the LAMFA axis for pedal percentage. Does this bring LAMFA map in sooner than normal (starting at 50% now) in order to control the fuel delivery with LAMFA instead of another map? I know someone is going to say "go read FR" but lets put it into laymans terms for the sake of this thread.

Thanks again to all who have been helping me work this out! Grin

If maybe I had a user manual for TunerPro I could tell you the how to, the only way I have it setup up is with the examples the program gives you on the setup of the extract tool. I have no clue what command would produce a file output that's the same, but I suggest one with some label as to the file being fixed. I have the MTX plug-in also and it corrects it and outputs the file with the same name. Sometimes it can be a problem if you don't check it 1st and flash it. I like just the word fixed just so I know and then I label it xxxxxxxxxx_fixed.bin just to be on the safe side.
