Is that normal?

[bistec]

I have a jdm d15b running on a p28 and the engine makes 220 miles on a full tank. Is that normal. Am i running too rich? Should i get a p08? With the z6 it was making at least 250 miles per tank. Thanks.

my z6 gets 320/tank. just run the stock ecu.

the po8 will need a 1 wire o2

I though both o2 sensor can be used with the p08 . Correct me if i'm wrong.

the po8 will need a 1 wire o2

So is the ecu the problem ?

 

[get_nick]

that's my guess also. check your timing to. also, consider a full tune up to. dizzy cap, rotor, plugs, and wires.

no both cant be used the p28 needs a 4 wire po8 needs a 1 wire
