Hey I have a P75 ecu with the 1980 board in my b18 turbo crx. I ordered the vtec conversion components and will have them soldered in shortly. The only part I am unsure about is where I will wire the vtec solenoid into.
Will any of the pins listed on the Hondata website for the vtec relay work?
P75:

• A15 ACC
• A20 PCS
• A12 FANC
• A16 ALTC - must invert output

Or does it need to be a specific pin since I am having the components soldered in and not using the relay? Thanks!

 

If you are adding the VTEC components to the circuits inside the ECU you would use the pins associated with those circuits. A4 VTEC Solenoid and D6 VTEC pressure switch.
