Hello,
I would like to retune my ECU I do not dominate all the maps.
I know how to connect download & upload, get logs etc but my question is:
Where do I need to start since I will change my stock header with a DC Sports, my stock exhaust with a 3" Perrin full line (Down Pipe, Catback, exhaust) and my stock intake by a HKS on my EVO IX MR? I already did a trick to get 24 PSI on the wastegate control tube...
What will be the right protocole to follow and how to check / retune seeing my logs?
Another question is regarding Baro compensation table, I do not think it's good to move it but I am living in Mexico city and my car will never be breathing under 7000 ft altitude. Any tip regarding this map?
Thank you very much for your help.

 

So you already have on the new parts? Or do you mean that you are going to put these new parts on? Do you have a wideband AF gauge? For me I decided to wait until I had most of my parts on and then started logging.

That absolutely has to move number 1. Log the car to see what its doing first before making any changes .
