searching turned up lots of noobs with stock cars getting bad mileage... this is different.


well with some help i tuned my vac areas of my haltech map.

my idle is 12.5:1 its happy there and runs smooth.

crusing on flat roads with 17vac or so its 14.2:1
crusing up hill with 13 vac or so its 13.5:1

now crusing down hill under high vac its still hitting 11s (needs more work)


soooo how would i work out the math to see what kind of mileage im gonna get.... or should i just fill up and see what it does?

what kind of mileage should i see with my stock port s4 t70 haltech setup?

any ideas would help... thanks.

It's impossible to even guess mileage just from AFR, let alone calculate it.

That's what everyone else does.

 

i thought 14s was inching to lean? ..

 

under heavy load 14's is lean, but for cruising and light load it is just fine.

 

ah that's right..he did say cruising =)
