Default ...DPFI to MPFI...

ok. Im about to do the fuel injection swap on my d15b. I already have the resistor box from an accord. The question is since the stock pm5 only has 2 injectors am i going to need to get another ecu to run the additional wires for the injectors... it only makes sense. But i wanna make sure so this bitch will run.

Any help is thankful. thanks guys.

si/ex ecu= pm6.......you can also use the 88-89 teggie pg7 ecu and the 90-91 teggie pr4. you will also need a 88-91 crx/civic si,hf,ex distributor, 4 88-91 civic/crx, ex, si injectors, 88-91 crx/civic si,ex intake manifold. since you have the resistor box the rest is labor in wiring.

Ya you need an ECU. I just did the change and noone told me my DX ECU wouldnt work. 88-91 CRX or SI also I think an 88-89 Acura Integra will work.

correct assuming your b16 and ecu are obd0. unless youve done an obd1 conversion. obd0b16 ecu's= pr3/pw0
