i am running a p28 ecu with a d15b jdm i am thinking of either getting my ecu reprogramed to p08 maps and timing or should i just get the p08 and convert it to o2 4 wire? if i reprogram the p28 to p08 i will have to convert it to 1 wire o2?

 

no you dont, you can have p08 maps put in your p28 and keep 4wire. honestly you arent gonna notice much differance.

well it will help my gas millage and won't run rich anymore that what i want i don't care realy about more power. how much will that cost around?

 

I chipped my P28 w/ a P08 EEPROM. I noticed better throttle response, and a noticible increase in my MPG. I would suggest doing it.....

 

thanks how much it cost you?

 

cutting out fuel when you're running rich will actually give you power.

chip the P28 with P08 maps, on a P30-203 base in Crome. Do a little minor tuning of the extended features and you'll have more power and better mpg.

you can do it yourself if you can solder. All you'll need is a burner and the parts to do it. roughly $40 depending on what you buy for a burner and where you get the parts.

 

thanks alot for the help

 

or just advance your timing at the dizzy, and dont worry about it. run 87 octane if you arent already.
