would this work ok or do i need to use a chip with the ecu, what is the vtec activation point??and it would plug right into my 89 civic harnessright?? are all the wires the same except the vtec wires??

 

i'd use a pg7 with a vtec controller.

i have a pg7

 

it wont work, timming is WAY off and it will run like dirt (if it even runs)...

you are going to have to get it reprogrammed so it will work correctly...

but the stock ECU will NOT work..

Yep. Timing and fuel are way off. It will run, but like crap. The PR3 and PW0 look for two o2 sensors. They read two cylinders at a time, and correct for AFR by alternately leaning out the cylinder pairs. The PR3/PW0 ECUs are also looking for a knock sensor that the D15B is not equipped with. Stay away from the "Mugen" chips.

Hijack a PS9 ECU to run PGMFI one-wire VTEC code, or convert a PM6.

or get a pg7 and vafc to better tune it

 

convert to obd-1 and use a p28. any obd-0 ecu will not work.

that head is the same as the z6 head. you need a z6 dist (its the only one that fits, unless some1 knows of one that does).

now.. all obd1 dist's use a 24 tooth sensor in the dizzy (i forget which sensor).

all obd-0 dists have 16 teeth on that same sensor.

so using an obd1 dist w/ a obd-0 ecu will throw it all off.

 

it works, BUT not that great.
Just to put around in, it's fine, but you'll get sick of it REAL QUICK

uhh....my obd-0 pg7 ecu worked with my JDM ZC vtec. please get your information correct before posting things you are uncertain of. 2nd i used a vafc to engage vtec and add fuel to 8500 rpm. and you dont NEED a z6 distributor, you need any obd-0 d-series distributor IF staying obd-0 which it seems like he is because a pr3 is obd0. theres is no "NEED" for a z6 distributor ever. you can use any obd1 d-series just fine. then again i used my STOCK obd0 distributor with my jdm ZC vtec with an integra pg7 ecu with a vafc.

thanks.
