Hey Guys,

I'm on a JDM IX GT running on a Ralliart ECU. My ride was previously running on a piggyback but have since restored to original.

I'm not sure if the tuner whom removed the piggyback loaded the ROM 89980000 into my ECU or if it is the original ROM. My ride was able to run with it but I find that the Fuel Map looks abit off. Thus, I downloaded a copy of the base map from the forum (compared them to the one I have) and found them to be identical.

I am wondering if anyone knows if 89980000 is the ROM for Ralliart ECU or was it for the stock ECU? I did a search and this particular ROM is not exactly common.

Appreciate if anyone can advise or post me a base map and ROM for the stock JDM IX GT.

In case anyone needs it for referencing:



Thanks!
