I've been running the RS ecu in an RSA with 93 octane + ethanol since 2007. No issues whatsoever. No fuel line problems and no knock activity, even when driving for hours on end in 100F heat and at high load. (Yes I've monitored it with the OBD RPM limit turned off).

If you are running an RS (+10HP) it doesn't make sense to waste money on a generic aftermarket chip. On a paper there might be a difference but you won't see that on the road.

Is that a for a real man size gallon, or one of those puny little US gallons. :-))
PS. All kidding aside, why do you use 94, when 91 is more than adequate ??

U S gallon, like it says. : )
Why 94? Prefer to not put ethanol in the car.
