Hondata

OMG...
They all worked fine with eprom - AC works normally.
To work with a Hondata the only change in every one of them was a socket...

I'll can change a socket to go back to eprom and the AC will work corectly with each of them.

I see You have no idea why AC do not work with Hondata...

OK:
1st P06 or P28 - with Hondata everything works fine except AC
2nd 37820-P06-A02 (from my another car - but there AC was removed) - with Hondata everything works fine except AC
3rd 37820-P1J-E11 - my back-up ECU without Hondata (with EPROM) - AC works fine
4th 37820-P1J-E11 - ECU in the car with ...

1st
37820-P06-A02
2nd:
Don't know. (No sticker)
Logika like P1J (blues connectors)
On the board is: 2PU6098-4508P1.

And the one without Hondata (on this A/C works fine):
37820-P1J-E11

When I connect ECU without Hondata A/C works fine...
A/C Has all new seals and presure is good.

Datalog. I switch A/W several times.

Hi,
have a problem. My air condition do not start. When I press A/C switch, the green light turn on. In Hondata ACSW also turn on, but ACCL do not.

With ECU with no Hondata everything works fine.

I checked with 2 different ECU's with 2 different s300 (V1 and V3).
