Ecu question
So I recently dropped a 00 b16a2 into my 98 cx hatch. I'm running the stock cx harness and ran all the necessary wires for vtec, knock etc. I have the 00 si ecu that came with the engine. Obviously I can run a jumper harness to the ecu for obd2a to obd2b, but I'm not sure if I will pass inspection with that. Is there a ecu that I can run without a jumper harness that will allow me to pass NYS inspection?

Obd2a p30 from a Del Sol. A p2t will not pass unless you get the ftp sensor, or your state allows monitors to not be ready.

Re: Ecu question
Check to see if you can have monitors offline, if they let you have one offline you can use the the p2t, or get the ftp sensor

Fool the ecu
We fool the ECU by providing a similar voltage that the FTP would normally send -- this happens to be around 2.5v. You need to acquire a 10k linear potentiometer: Radio Shack Part Number 271-1715.
The outter 2 pins are going to be +5v reference and ground (does not matter which), while the center pin will be your output feeding back to the ECU pinout.
(Before you hook up the pot's center pin to the ECU, use a multimeter to adjust the output to 2.5v.)
Here are the 96-98 civic & integra ECU pin assignments:
D10: +5v
D15: FTP input
D11: GroundHere are the 99-00 civic & 99-01 integra ECU pin assignments:
C28: +5v
A29: FTP input
C18: Ground
