The disassembly efforts for the 09 Ralliart have started and I wanted to share some differences in the ECU Rom between the 09 RA and Evo 10 that have been found so far.

09 Ralliart and Evo 10 injector scaling and latency tables:

Looks like the 09 RA and Evo 10 share the same injectors.



09 Ralliart and Evo 10 injector scaling and latency tables:

Evo 10 on left, 09 RA on right. Looks like the RA has a lower rev limiter and the boost limit is lower, which makes sense since it runs lower boost than the Evo 10

 

So, now that you've gotten your hands on an RA, have you tuned one yet? Or tried to throw the EvoX tables into the RA tables?

 

No not yet, still alot of tables to find. Most of the tables are very close however so it should go smoother than the 10 did.

 

It appears that the RA and Evo X are very similar.

 

Very Nice. Looks fun.
