My friend had a GSR in his hatch and he decided to go with a H22 cuz GSR's are gay Any ways, we are using the GSR harness on the H22 with the stock P13. I looked up the P72 pinout to see if any of the wires in the harness at the ECU would need to be changed. A12 is coolant temp switch on the P72, does that turn on the fan when the coolant hits a certain temp? I'm assuming it does. B9 is starter signal on the P72 and starter cut relay on the P13, are these the same thing or do they need to be changed?

Also, I found the P13 pinout on Honda-Tech and it lists EGR where the MAP sensor 5 volt should be.
Here is the pinout, if you look at pin D19 it shows EGR Valve Lift Sensor. What pin on the P13 supplies the MAP with voltage? I hope this all makes sence, I am kinda tired.

Thanks,
Frankie

 

what year is the motor , and what year is the harness?

nothing should have to be done really though.....except wiring up the EGR. and the alternator wires need to be extended.

 

Fuck Gsr's right frankie.....hows joes swap coming out...hit me up some time we need to hang out....hopefully the gsr will be done by Track day

 

The motor is a 94 and the harness is a 99. I know we need to rewire the dizzy, the alternator wires need to be extended, resistor box needs to be wired, and we are not hooking up the EGR right now. We're probably gonna end up using a different ECU cuz he doesnt want the JDM ECU.

What size are the 4th gen Prelude injectors, 345cc? He has a set of 310cc injectors that I was thinking he could use so we dont have to wire the resistor box. I know the car would run lean since they are 310cc and not 345cc, but how lean?

 

are you running obd1 or obd2? and what dizzy are you using, and internal or external coil?

 

IMO , i would run a chipped/ socketed ecu... have the knock sensor , egr , and iabs removed.

 

Yes GSR's are ghey Joes swap is going ok, it would have gone better if him and Amendolre had read the mount instructions BEFORE they put the motor in You still havent got that damn car finished

 

The dizzy is OBD1, I'm assuming since the motor is a 94. I didnt even pay attention to the dizzy but I think its internal coil.

Thats what I was thinking. The whole IAB system is fucked cuz the box under the manifold is broke. Would you get a local tuned chip or would you buy one? www.JDMShit.com has a H22 chip for the P28, I was gonna get that when I had my H22 Civic.

 

I would go with a Phearable.net ecu.

i would just pullt the IAB'S.

Also you need to convert the timing belt tensioner, from a hydrolic to a manual. I say this because the hydro tensiors have been known to fail , and not to mention they are a pain in the fucking ass do deal with.....you can use a h23 manual tensior.

 

yea frankie pm john im sure he can get joe an ecu within a day or 2.
