Hi guys, I finally bite the bullet and traded my 08 STI for a New Zealand new 2004 Evo8 FQ300, modified by Mitsi NZ to 300hp. In Black! which seems to be rare, Mitsi NZ only done 10 of these FQ models so I am very happy to get a ltd run.

My factory ROM is 93660005, it looks like the fueling is mapped quite lean, I have only just got the car tonight so haven't put the wideband up it yet.

What Tephra rom do you suggest I run with? 96260009-v5.10fix?

Does any 1 have a well defined xml for 93660005?

Thanks Phil

 

you will probably find it wont be lean.all the FQ300EDM/JDM cars iv looked at are into the low 10s AFR.96260009 V5.10 would be the best rom to go for unless you want the V7 rom.
