Hi

does it matter if the car is cold or hot when the ecu is installed?
i installed mine and the car was hot and i got a cel and a no vtec.
i just plugged the p2t back in and every thing was fine.

should i install it back when the car has been sitting for 6-8 hours or is it ok to installed after a 2 hour drive?

Remove and install the ECU only after disconnecting the battery.

i did that, i disconnected the battery and then installed the ecu.

should every thing work straight away or does the ecu need a time to read out of sensors and stuff so the vtec works?

i bought the p06 with a b16a2 basemap and with vtec. launch control @ 3800rpm every thing works exept the vtec. i didn't have the ecu in longer than 15min b/c of the vtec issue. should i install it with the car cold and just try it

It makes absolutely no difference if the car is hot or cold. If you're getting a CEL for vtec is possible that whoever did the vtec conversion on the ECU did it wrong, or never converted it at all and just socketed and chipped it.

i think i have found what is wrong.

there is no vtec oil pressure sensor so i need to by pass that with this:


so i just add wire between the a4 and d6?

The question I have is what does it work with the P2T which also looks for a vtec pressure switch?

Yes. I'll check after but I think you're missing IC13 on your ECU I mean it's definitely not there, but I *think* you need it. I'll check the converted P06 I have in the garage later today and confirm.
