I want to do the tephra mod v7 on my stock ecu, main reason i just did the egr block off and ill be doing exhaust later on this week with no cat, but i want to disable to cel for the rear o2 and egr. How do i convert my rom to tephra for these.

 

2005 evo 8 btw so i need to convert my hex for the immobilizer.

 

Start here, should answer most of your questions:

Ok so I need to copy my fuel and timing maps to the bigmap translator then copy to the tephra mod rom?

 

For those maps, yes. Any other maps you want to carry over (idle tables for example) just go straight from your current map to the new v7 one. Some tables, boost notable, work differently in v7 compared to stock roms, so there may be some adjusting to do.
