Hondata S300 P72ecu - Limp Mode - B16A japspec EK4 OBDII possibly OBDI motor

[Riviera]

Ok it has been passed over in brief in other forums and threads but no full on explanation

EDIT: ITS P28 FFS.... Ive found that some wiring could hav been altered in the loom also.... p28 is operating the IACV and its constantly on making a buzzing noise... sigh...

ive got a EK4 so running a EK4 loom with a B16A in it which has a burned out IAT sensor in the intake manifold...

now that doesnt matter because its running OBDII ECU and has a IAT in the Intake Arm.

When i install the Hondata S300 P72 ECU with OBDI to OBDII conversion harness, should i be experiencing problems if i havnt moved the IAT to the Intake Plenum (Top side of runner One).
Now to my understanding the OBDII motors have the IAT in the Intake Arm and OBDI in the runner.
but what i also understand is that the OBDI B16A has a Cable Gearbox... But i have Hydraulic - Possible Swap... not sure

What i am experiencing with this setup is a 4k RPM limit (Limp Mode) as if its got a launch control... lol
too scared to attempt at taking it for a drive, so i have not yet... ive uploaded a standard B16A map also.

if someone could please verify what might be causing the issue that'd be fantastic. Take it to a shop... Aint got time lol, i'll just drive around standard ECU till i find my answer.

thanks
