i am swapping a d16y8 auto in my 5 speed civic
both d16y8 but the auto uses the 3 wire iacv plug which i do not have
i know its possible to switch from the auto 3 wire to a 2 wire pretty easily but is it the same for the opposite

is it possible for me to convert the 2 wire to a 3 wire and add a wire to the ecu side
considering my car is 5 speed

the ecu im using is a hondata s300.

 

Hondata is not an ECU.

What exactly are you trying to do here? If you're planning to run an automatic Y8 ECU it's gonna throw transmission codes, btw hondata only supports 2 wire IACVs.

 

p28 with hondata s300 installed

what im trying to do is run the auto y8 motor with the 3wire iacv on it. is this not possible say a manual y8 ecu p2p i think
i also dont mind codes its temporary until i build the original motor in it

 

You are running a 5 speed transmission though right? Just get a 5 speed Y8 Im ('96 - '98 ideally, the '99 - '00 have air injection holes you'll need to block off) or drill out the back of the IM and install a 2 wire D-series IACV and use an OBD1 throttlebody.

 

Damn this sucks

 

yes im running the 5speeed trans

is there a way i can run the auto ecu and run the wires straight from the plug to the ecu.
i dont want to go find a intake manifold and swap out it out.

 

ended up drilling holes and using a obdI iacv and blocking the 3wire bullshit honda made

 

hate to bring up old posts but I would have swapped you IM's if I had seen this

 

drilling for a 2pin iacv was easier for me since i had a iacv laying around.
