I have an Evo 8 ECU swapped into my Evo 6 and it runs fine but it runs very rich - about 9-10 on the AEM UEGO. Could someone take a look at the rom ?

to support the FIC 1050's, Injector scaling is set to 1008

injector voltage latency compensation is set to
4.44
3.192
1.752
1.032
0.84
0.5760000000000001
0.432

I have attached 2 roms.
One is the stock Evo8 Rom with FIC 1050 injectors. - Runs Lean -17 to 18 and higher AFR at idle and cruise
The other is a Tephra ROM with FIC 1050 modified specifically for Evo 8 to Evo 6 Swap. 10 or less AFR at idle and cruise.

I will get a pro tune eventually, but car needs a bunch of maintenance and still a bunch of mods left to do. Id like to get a decent tune going in the meantime just to drive it around a bit.

You should check on lancerregister.com
I am sure the Brits have a lot more experience with putting an Evo 8 ecu in a 6.

lol thats where I got the ROM from. My issue has to do with the fueling and that should be the same across E8 and E6. Same engine basically, and now running the same ECU.

Should take it to Magnus Motorsports (should be close to you if you live in Toronto) and get it dyno tuned http://magnusmotorsports.com/contact-us/

They will sort out the fueling with the tune.

Have you attempted any fueling changes such as the injector scaling and latency?

yes those have both been done to compensate for the FIC 1050 injectors. Values added to first post.

I am asking if you have tried changing them after trying the values you currently have set.
For example, my PTE 1200 injectors:
Scaling at 975
3.312
2.016
1.512
1.2
0.672
0.6
0.48

Try adjusting your scaling downwards to begin with on the ROM that it is lean.

Ok will try playing around with those. I've run these injectors for a long time with these values previously on an Evo 9 and on my Evo 6 with the Evo 6 ecu.

It's only been an issue with the Evo 8 Ecu swap which is why I doubt it's an issue with scaling.
