Re: Holley EFI+555"= Fuel Mileage Testing
Jim, good to see that I'm at least in the ballpark. Just suprised that my 850DP was within .5mpg of the MPFI. But the question is, when you get to 15-16-17:1, although the motor is running, how do we know that its most efficient there? You dont really know anything until you get back to the gas station and fill back up, be nice to get some sort of data while the car is running.
Can we somehow hook-up one of those MPG gauges to this system, so how, some way?
Joe, no problems pulling OD in top gear at all...its pulling top gear on slow back roads at 1500-1800 that are presenting the challenge. Will give the system a little more time to see what it can do.
