Hoodwinked

I have a p28-a02 obd1 ecu. I am wondering if I still need a resistor box or not. Do the injector drivers use low or high impedence? What year did honda switch over from p&h to saturated? Also, with my Hondata, all I need is Hondata, p28 ecu, and harness right? No other wiring necessary? My engine is a obd-2 b16a2. thanks

All honda ecu injectors drivers will accept high impedance injectors directly, the non obd ecus used an external resistor box with the low impedance injectors.

Dr Honda

10 to 14 ohms will work.

in response to your questions 96 and up are saturated p& h is before that [edit by falcongsr - this is incorrect see below]

You can run either injectors with that ecu. Just remember to have the resistor box if you want to run the P&H injectors. Likewise, no resistor box is required for the saturated injectors.

Wrong: 92+ Civics use high impedance (saturated) injectors.

no they don't i called acura dealership and they said 96 and up is saturated below that is p & H that is at least in prelude and acura in those years here are some other posting with exact numbers i'll find the link with the website soon 1988-'91 Civic Si/CRX Si Peak and Hold 240cc
1992-'95 Civic Si/EX Saturated 240cc

1996-'00 Civic Saturated 240cc

1990-'91 Integra RS/LS/GS Peak and Hold 240cc

1992-'00 Integra LS/GS Saturated 240cc

1992-'96 Prelude Non-VTEC Peak and Hold 240cc

1992-'96 Prelude VTEC Peak and Hold 345cc

There.

You tell me I'm wrong then say the same thing I said???

falcongsr

wow

that's not what i am talking about i am talking about the set up he had would it work would he need a resistor box u need a resistor box if u use 345 prelude injectors
