Really hate to post this, but been putting multiple searches and can't seem to find any answers to how or if possible to switch from Evo IX maps 88590013 to 88590015. I want this since there seems to be more support for the latter one. Kinda new at this. Been reading alot and just came the issue when trying to control boost with the ECU.

Thanks

 

i wish i knew how to do it, but i can tell you that it is possible. i was just tuned by jestr over the weekend and he upgraded me to 88590015

 

Just load a v15 ROM and change the immobilizer to the one in the stock ROM. They are compatible, so you don't have to do anything special.

 

thanks, gonna try that once I get the JDM 3bar map sensor issue I've got resolved.

Now to find a V15 Rom

 

pm me your email address I have a v15 stock rom

 

My car seems to run quicker with the 13 version, could be in my head but sure seems snappier.

 

Just got the 015 rom from a member, thanks for the responses. I will test my butt dyno aswell to see if there is a difference between 013 and 015.

 

Sorry to bring this back from the dead, but I am just getting into tuning and I am interested in the merits of the 015 over the 013 (what I have).
