I m sorry to hear that.

But I guess the VTC calibration is also changed when swapping in a US ECU?

Oh I see... Not even using a hot knife for the seal? :/

I guess I need a 37820-RRB-A04 to 37820-RRB-A14 ECU and matching Flashpro then?

Will I keep my cruise control, shift light, VTEC light and center display items with the US ECU?

Best regards

Hi Guys

Does the FN2 have the PCB traces of the USDM SI ECU?
If so can I not just add the missing components to the FN2 ECU to drive the solenoid?

We did that on the old OBD1 non VTEC ECUs to make the into VTEC ECUs.

That way I do not have to buy a USDM ECU and a new flashpro.

But is between rocker and cam better?
Or what else could cause the Knock noise?

Hi Hondata

Thank you for the answer.
I measured between between rocker and valve stem.
That is the Honda procedure according to the K20 shopmanual?

I used 0.23mm for intake and 0.26mm for exhaust totally cold. That is what was written on the TODA CAM card?

Hi Guys

Car is also running Skunk2 CAI, RRC intake manifold, 2.75" catback, modified circuit sport exhaust manifold, and it is from that setup the map originates.

I have just installed: Toda A3 cams, Toda valve spring, Toda timing chain tensioner and new Honda chain.

I have tried to make knock ...
