Hi we got are eg dynoed there.
H22a bottom end
H22a7 head with inlet and cams
Costum maini and exhaust 2.5 right back
Egr delete
Balance shaft delete

Had p13 with spoon copy in it
Made around 160bhp lol
After couple runs it done its usal spluttering and missfiering. Air and fule was way rich not.

Pluged standard p13 in made around same peak power with less power lower

Plug standard p28 in same again made same power but with less revs. ( rev limit was way lower)

Still on them 2 ecus it run abit to rich not as bad as frist ecu

Then went got m8s stanard p30 ecu
Made 180 odd bhp. With no spluttering
Changed dizzy cap to new one and made 198 bhp lol.

Strange. Thinking p13 ecus were past it maybe.

Any thoughts on this be welcome

Also code 23 nock sensor keept comming on all day
We thing the sensor is drokked as its taped up to hold it on

If the knock sensor is drokked, that will retard the ignition, you will be well down on power and may get misfires.
If the knock sensor isn't correctly/securely fitted, that will have the same effect (it will rattle and think that's a knock).

From that list of ECU's you've mentioned, which ones came from a jdm car and which came from a UKDM/EDM car?

Which injectors are you running and are you running with the injector resistor block or not?

The 2 p13s and the p30 are jdm

Lude injectors with the box in pal

Then those 3 ecu's definitely require a working knock sensor and that is most likely the source of your problem.

Can you whack on a JDM ECU to a standard UK 2.2 and expect to gain anything other than a lightning of your wallet?

Nope. No positive benefit and it will in fact cut power because the UKDM won't have a knock sensor so the JDM ecu will log a fault code.

The way to gain a small amount of power in a UKDM is to fit a spoon chip to the standard ECU.

The Spoon Chip, filed next to the Hen's Teeth??

They used to be readily available as copies on here, for a very resonable sum.

Unfortunately the member who offered that service has been very quiet of late.
