could both be used for z6? whats the difference between the two? i know p28 = z6 and p08= d15b.

 

u wouldn't b able to pass smog with the p08

 

p08 runs a 1 wire o2, p28 runs a 4 wire o2.

 

your better off with the p28

 

Hey Really Im about to swap A JDM d15B wich would be best P28 0r P08

 

like said above the p08 uses a one wire. and the p28 uses a 4 wire.

the maps are almost the exact same, even with a 4 wire o2 and running a p08 your not gonna see any power loss or gain.

however, if you use the p08 with your d15b you will get better mpg

what i did was put the p08 base maps on a p30 base. chipped the ecu and used that. worked 100% and ran very good a/f ratio. for stock it was like 12.5 WOT
