phase 2 ecu and phase 1 wiring ?

[FQ200turbo]

can a phase 2 ecu work in a phase 1 engine wiring without lambda work ?
tks

any help ? :(

not too sure - i know phase one works in a phase 2 car as ive done this myself.

If the phase 2 ecu doesnt have a built in imobaliser then it should work fine.

what engine ??

[FQ200turbo]

F7P

[schakal]

can you explain this a bit better , why do you want to
run it without the lambda ??
if it helps r19 16v ecus seem to work on all f7p s ragerdless
of ph etc .

iam making a engine swap, i have a phase 1 wiring, and a phase 2 ecu
is the only diference in the wirings is one having the lambda and the other dont ?

[Clio_GTT]

They both have a lambda sensor

ayee as far as i know ,all valvers had lambdas ^^
may be someone cut it off the wiring ??

I used a ph2 ECU in my old ph1 valver from Stan ages ago and it was fine. Used another ph2 board on my Williams (it had a swappable EPROM chip carrier) and that worked as well but the board had a fault and was revving at 2.5k. Still, it worked.

Pretty sure ecu pins are the same, it's the white and brown plugs that differ

I have never managed to get a Ph2 ECU to work in my J-Reg Ph1, just flashes immobiliser light.
