So I finally broke down and bought a Tactrix cable to check out my "toon" and attempted to read my rom. Upon doing so, it appeared that all my meta tabs had strange values along the X & Y axis. My rpm scaling does not go up in increments of 500 and my load doesn't increase in units of 10. My RPM's show "6023" down the Y axis and my load shows "482" across the board. Any ideas as to what is going on? I'm currently running Ecuflash V1.35 w/ an unlocker in the background. When I first saw my Hi octane table I knew something was way off when most of the cells contained "inf" instead of actual values. Any help for an Ecuflash noob, but an Evom vet would be appreciated.

Update: I updated w/ my original scrambled map and my attempt to unscramble the maps. I changed the ROM code to (94170015) to get it to display values. The only thing I'm trying to get to work is the RPM / Load Scaling. I tried to edit the map definition for each table w/ no luck. Any ideas??

Scrambled


Unscrambled

 

Well your sig explains it all. The tooner you have in your sig scrambled the ROM.

 

Doh, so what can I do to unscramble the ROM. I thought that he only locked the ROM and didn't scramble it?

 

change the rom id back to what it should be

 

The ROM version that is currently on the car is 05 USDM VIII (96940011); are you saying I should change it to 03-04 USDM VIII (94170015)? If so, where do change the ROM ID?

 

sometimes tuners change the rom id in ecuflash i came across one changed from 98640014 to 98655014 , its under misc then int id .

 

Thanks for the help, I found some threads about scrambled ROM's and how to unscramble them. I'll troubleshoot when I get home to see if I can get it straight.

 

Alright, I'm making some progress. Changed the Init code to 0001 and also set the correct ROM ID in the hex table. The values in the table look accurate, but I'm still having issues with the scaling on the X & Y axis. The increments are not the standard 500 rpm increments and same w/ the load. Any ideas on how to get the scaling?? TIA

 

can you post up a screen shot of the tables .

 

+1. Best bet to get some decent help.

 

Download a factory 96940011 ROM and then the annoying way to fix it (but works) is to open each subfolder (ie HO fuel map, LO fuel map) and then click edit map definition, compare the stock and the one you have, yours has a wrong address. Match up those addresses to what the stock values for your ROM is and it will work.

 

It sounds like your issue now is the scaling endian for RPM and load. Edit the scalings for both values and change the endian and see if they display correctly.

 

Bump for added maps in original post

 

To change the endian values ...

Right click the map name in the left column (fuel or timing)
Select Edit Map
Click the scalings button in the new window
Find "load" in the scalings list
Select the Edit button
Change the endian value
Exit this screen and repeat for RPM
Save and exit all windows

You can also go in to the evo7base.xml file and change the endian for RPM and Load by hand.

 

That's the funny part of it; I have edited the Load & RPM to mirror a stock rom and it is still giving me the funky values.
