Hondata

Hi,

I swapped k24a2 in my rsx.

What calibration should i use from new calibration?

I selected tsx04-05 stock.cal in the rsx (type s)- PRB

But now i have 2 error codes:
P1259- VTEC System Malfunction (Oil Pressure Switch)
P1166- Heated Oxygen Sensor Sensor 1 (Primary HO2S)

Any suggestion would be highly appreciated. Thank!

What ECU are you using this in?

Hi,
It is a PRC ecu.

Fixed the error (P1259) by disabling the Vtec oil pressure switch.

P1166 still pops-up. Is it because it's a JDM ecu?

Also, the ignition timing fluctuates at idle, i think that is a part of Honda's idle control. But when i switch the A/C on, the engine drops rpm significantly from 1000rpm to 500rpm or below and then back to normal.

The PRC uses the same sensor as a PRB, so if you have that error there may be an issue with the sensor itself.

The ignition will fluctuate at idle as that is how it controls the idle.

Hi,

Ill replace the sensor then!

Thanks alot!
