Hello everybody,

I just to put ralliart rom into my jdm7, but I see a lot of stange values in fuel map and ignition map. In my stock rom load is up to 260 and ralliart rom to 300.
Need I a rescaling? how?

 

You just copy and past you original Map onto the Ralliart map, and do the same for the top load values, then continue the load values up to the 300, and then start adjusting your 260-300 maps. r3compile explains it well in his "How to tune Evo" videos on youtube.
