Hondata

having issues with the wiring going into the ecu,

instructions show the purple cable connecting to A16, my ecu plug does not have anything plugged here which makes me question where the ALTC cable is? do i have to remove this cable where ever it is before plugging in the purple cable to a16?

im running s300v3 with the transistor q37

If it has the wire it must be de-pinned, if not then you need to crimp on the correct wire and then put it into the ECU plug.

You should contact Rywire to ask why it is missing this wire though, as that is unusual.

i got a reply back from rywire giving me instructions to install the cables into the ecu just as hondata instructed.
they didnt seem to give me an in depth explanation to why the a16 was missing, i asked if the altc fuction is not present on my wiring...
they just replied back with ''thats correct''

anyway i have since wired everything up as instructed via hondata and its all working fine. would swapping to the cpr system mean i would need a complete new tune?

No, you should not need to retune after installing the CPR.
