Outside the usa they only use the 91 version, if you have good fuel copy the BASE TIMING B table from a 93 tune to your rom.
Tunes tables in roms for same tunes in different countries are same ie a Petrol 91 EL header tune tables for a A01G is same as A01C but the roms are different.
The oft guys copy the tune tables from the usa roms into the roms for the different countries

Thank you for the help. I will try that once I get back home.
I keep arguing with others here that the 93 AKI US fuel is better than our 98 octane but they insist that ours is more knock resistant. I guess I'll find out soon.
P.S. Thank you and Kodename47 for all the helpful posts on this forum. I've been lurking since 2012 but I finally started to mess around and try to learn how my car works. It's been fun so far.
