Fuel Economy Guage

laptop style. for anyone running OBD1 or 1.5 and has a laptop/ALDL cable, if you want this kind of capability, let me know, i'll send you either a finished ADX or the information on how to do it yourself.

 

or if anyone wants to see my notes on how to do so, feel free to ask.

 

(BTW: which forum does this belong in? i saw Bob's 1.5 to 2 conversion thread here, and it's about as close as it gets.)

But my DIC works fine :lol:

 

Wonder if I can do something like this with HPT. Pretty sure I can do a custom PID cell and datalog that.

 

if the GP and MC had a DIC, i probably would have never went through this, but it's said and done.

 

i'm not sure how HPT logs stuff compared to TP, but if you want the equations i'm using to come up with my seemingly accurate numbers, feel free to ask.

Kinda cool..

My OBD II scanner does it for me. I'm rather surprised HP doesn't have it built in.

Hit me up with the equation and I can scan tonight and see how it does

(104.45-Y)/42.932

 

X/((16.7-W)*.0000212*Y*Z)

 

first one is to scale fuel flow based on manifold vacuum since anything other than the vacuum at WOT doesn't flow the rating of the injectors. this is based on a 43.5PSI FPR. different pressures may require a different equation.

 

Y=MAP kPa

 

second is the main equation

 

X=MPH, W=the scalar for fuel flow(above), Y=RPM, Z=Final BPW
