i want to know what fule presure you guys are running. my friend has that set up adn its reading 36-38psi and is running the stock 99 si ECU and is throwing a code 45. if i raise the fuel pressure couldnt it get rid of it? i want to see if he can go that way b 4 swaping to a P28

 

ill tell him to get a regulator!

 

yea i had the same thoughts about running a P28 with the convert harness with a custom set up for it kuz its throwing a code 45 right now

 

Your prolly running waaaaay lean. Check your plugs and see what they tell you. Bump your fuel pressure up to 45psi. I have my B20 no tec @ 43 right now... Runs alot better then at 38....

Good Luck

i just cehck out the car and its at 38psi but hte car is throwing a code 45 which is rich in fuel? this doesnt make sence

 

up'ed the pressure to 45psi and no light...lets see if it works!

 

been 2 days and no check light...i got rid of the code!...but still need to get a P28 to tune the car its really lacking in power

 

thats all up to the owner im just here to guide him i say the same thing chipped or S-AFC
