well im running an obd1 JDM b16 that was wired to run a p2t (2000 si ecu), just picked up a obd2b to obd1 jumper harness, and now im running a chipped p30 that i borrowed from a buddy of mine. my car was running kinda rough with the p2t because my secondary 02 was malfunctioning and it was throwing a CEL. now that im running the obd1 p30 it doesnt throw any CELs but was wondering if running a stock p30 or a chipped p28 would be better. noticed with the chipped ecu that my gas mileage has gone down a little because it wasnt orignally meant for my b16. any input?

 

I ran a chipped p28 with the conversion harness on my b16a2

 

is your car obd1 or obd2. if it's obd1 the correct ecu would be a p30 or yes you can use a "chipped" p28 but that's ghetto imo. If its obd2 then you can run an obd2 p30 or a P2T si ecu. A JDM PCT or P73 ECU would run the engine best if you're obd2 but in most states you won't pass emmissions testing because usdm obd2 testing equipment won't read a jdm ecu.

 

i use a chipped p28 on my 2000 em1 si. it works fine and no cel. id go with that.

TUNED P28 ECU "chipping" is for when you're 16 and you want mad sounding vtak!

 

well my car is obd2, and i passed emissions with it obd2 a couple months ago when i was running the p2t.

sounds like a p28 with a chip then would be best?

lol bump

 

S300!! got it and havent looked back since

 

I agree with SirRevvs. A DOHC ECU will run the car better than a chipped SOHC one..

P30 gets my vote.

 

i say get the ecu for that motor. or if ur gonna go p28 atleast get a b16 basemap
