On 94 octane 15% ethanol, full headers and catback, LWCP, modified HKS V1 superchargsr and Ecutek dyno tune I am averaging approx 20 mpg/ 350 kms between fillups.
When cruising it is around 14.7 AFR, and as low as 12 AFR when accelerating.
Was getting several check engine lights, P0420 cat, P0068 powertrain and another one for bank 1 running rich.
Recently disconnected the leaky shit oil cooler and switched from 40 weight oil to 30 and now the check engine light seldom lights, and they go out on their own.
I guess thats the sacrifice going FI. I can chase the issues but sometimes its something that seems completely unrelated by the looks of things. Luckily I dont ever recall any knock, probably because it sometimes runs on the rich side.
Update: three days maybe 200 kmsincl.bumper to bumper commuting today, no CEL yet!
