Gotcha on how to use the wideband Russell.
Just curious, can you re-run the numbers for me just one more time? This time, let's use the theoretical, all-out eco version of the ZX2. Have 2-3 psi, 250* IAT's, 35:1 AFRs, 1700 rpm @ 45 mph, Cd of 0.15, RRC of 0.006 and the weight of 2300 lbs please!
The turbo is more efficient, no question about it. The cost of the components, the time spent with the car down and the tuning software simply put it out of my reach right now
Ty, I need EVERYTHING
and you'll be getting 50 mpg out of your new-to-you Fiesta soon, no problem!
