Hello everyone!

Recently I picked up a tactrix for my 9. I dont have any cats and have an EGR delete, both of which im throwing codes for and getting a CEL.

Wondering if there are any tutorials for taking my stock map and modifying it so that I can clear the CELs and pass my emissions test.

I have found some misc articles talking about it, but I cant find any full fledged tutorial. I talked to a tuner who said id need a tephramod map, but I have no clue what that is and he wont message me any more lol.

Any help is appreciated! Need to not be riding dirty

 

There's should be a sticky thread on how to download and install tephra. You will need to find the rom that matches your ecu but since you are so new at this I would refer to a tuner. It's not hard to do but you would have to retune the car since there are new tables and parameters that are not present on the stock rom.

 

Is this something I can do with ECUFLASH without a custom tune? Any guides on how to modify the periphary tables to remove EGR and Rear O2?

 

I used 2 Spark plug anti fowlers. Easy Peasy. Just drill a .5 inch hole on the bottom one to make it wider,

Link here. This is EXACTLY what I have done and it has worked since Juen 2003.
