Initial Disclosure: Apologies in advance, I really tried to contact about 10 members who mentioned they did this "JDM block with USDM harness + ECU + vtec solenoid oil pressure sensor" but nobody replied (basically no longer in the forum). Please don't crucify me for asking this... AGAIN. It's really not properly documented in the forum, I really searched for days on this

Hi Experts,
Could somebody confirm the following?: "A JDM F20C block can be used without any problem with a USDM F20C1 harness + USDM F20C1 ECU + USDM F20C1 Oil Pressure sensor installed in the vtec solenoid".. According to my research the answer is YES but i'm not fully clear about this and I failed in getting confirmation from members who did JDM swap.

My big questions are:
- What about the AFR when using a JDM block that generate more compression on the pistons? Is the USDM ECU capable to compensate/adjust AFR?
- I read about a second knock sensor in JDM. Is that correct? Just leave it there unplugged and all should be fine, right?
- Any other feedback? Just want to put a fresh JDM block and use my USDM accesories, harness, ECU,etc. A clean swap just changing the block and keeping all the rest.

Thanks in advance for your guidance.

some say that 2.2 can work with ap1 2000 ecu .I dont think that u will have problem.

 

 

Curious if this is a merely lean code or an actual lean condition.
