s13 MPG Gauge/Meter (Real Time)?

[P4rD0nM3]

My friends BMW has this on his dash and I think it's pretty useful for me since sometimes I tend to have a heavy foot when driving. It says how much MPG it is...so, i'm wondering if APexi, HKS, or whatever has this gauge/meter...

Like this one but for a car.

EDIT #3: However, they are not compatible with 240s.

1. Pull into gas station
2. Fill up until the car can NOT take any more, make note of the number of gallons (down tp the decimals) of gas you pumped
3. Pay attendant (pulling off in NC will cost you your license)
4. Sit down in car
5. Hit trip odometer BEFORE you start the car
6. Drive til next friday
7. Divide the number indicated on the trip odomoter the following Friday by the number of gallons of gas you just pumped.
8. The number you have at the end of step 7 is your average miles per gallon, bitch when it is a substantial amount less the next week.





Those 9 steps mean more to me than some bullshit gauge.

my dad's caddy, and his RAM have those.

I get 99mpg going downhill in his truck.

that's only because you are off the gas and that guage reads on 3 second pulses

Doesn't Apexi make one?

my cousin's 74 ford fairlane had one. it was fun to make it go up and down with the gas pedal

some benzes collect data and tell you average gas mileage since you started the car and average gas mileage since the car was made.
