I was intrested in doing the tephra mod, if I change over to the tephra mod 94170015 rom would I need to copy and paste all my values?
I know that I need to do the immobilizer code but what about everything else?
could I just get it tuned from his modified rom? I still have the stock tune

 

are you starting from 94170008 or 94170015?

if yes - then yes running 94170015 is fine.

if you are _sure_ your current ECU is "untuned" (ie stock) then just copy your immobiliser code and thats done!

BACKUP YOUR STOCK ROM TO SEVERAL LOCATIONS (ONLINE EMAIL IS A GOOD CHOICE)

 

yes I never tuned the car yet, thankx for the quick response
I'm excited about trying it out, heard alot of great things about it

 

Backups, backups, backups. Always backup your original rom to a few locations before doing something like this !!

And good luck!

And if you do something stupid, FFFF is the answer

 

FFFF(uck!)

 

...And never forget to first paste your immobilizer code in any ROM you will upload to your car to be able to use your backup ;-)
