Hi, i have a 98 civic with a 00 si b16 swap. Im currently running a p73 ecu which burns crazy gas and seems to be overkill. Which ecu is my best shot at buying. I want something that will feed my b16 properly. I looked around and found that chipped p28 might be my best bet. Ps i currently have intake/headers/exhaust as mods.
thanks,

 

a p28 chipped and TUNED,

 

all i need to have the p28 up and running is the conversion harness from obd2 to obd1 correct? I wont need to change my distributor or any thing right?

 

just get a juimper. you need a obd2a to obd1 harness, you can also use the stock si ecu, but you will still need a obd2a to 2b harness.

 

i recently just got the stepdown harness to use a 95 ecu. i got a chipped p06 on crome tuned.. **** works mint. (00 civic si b16a2 with cold air intake.)

 

use the p30 ecu. comes from the del sol si with the b16a you will need a jumper harness. im running that ecu with a b16a2 and it runs perfect. no tune.

 

i have looked into buying the p28 since ill be able to tune it better for my setup, and change the tune later down the road. However i see there are "P06 ECU converted to P28" ecus going for cheaper prices then the p28 ecus. Is there any cons in these ecu's?

 

jumper harness obd2a to obd2b and buy a p2t em1 99-2000 or get a p28 chipped/tuned
