H22 problem 6500rpm

That should throw an ecu light. But there is none?

sorry for the daft question but what's the spoon valve

It's a typo, that's what

I meant spool valve.
See page 5-8 of the service manual

Should it? Or should it just think the lambda sensor has not got warm enough to start reading, which means the ecu stays only running off the coolant temp sensor?
I dunno - not tried running it with the lambda sensor unplugged, but they're funny things to fault find (can't resistance test them etc.)

No bulb in ecu light as if was on all time with decat

The decat is a different light and circuit and does not trigger the ECU light. You need to put the bulb back in and check and fix the codes.

I think so, as a faulty o2 sensor will trigger a code, I'm not 100% though. But +rep for calling it a spool valve rather than a solenoid.

Can't seem to find plug to bridge for codes as it's a h22a7 swapped civic coupe the joys

My approach would be to change that sump (most likely) and fit an o2 sensor. After that find a pin-out diagram for the ECU you have, you should be able to bridge the pins a the OBD connector to get codes.

Yeah hopefully change the sump this weekend and put the other mani on with O2 and see if that sorts it

Another thing to mention is my mate welded my engine mount not sure if he disconnected the battery when he did the problem started the next day or is that just coincidence

It's entirely possible.

Just thinking about the sump, I think the A7's should have an ally one, but yours is steel? I don't know if that could also be a factor?
