  1. Closed loop on idle

    in Link G1

    Thanks Scott,

    The ECU supports only full time open loop or closed loop. I wondered if there had been any updates to support closed loop on idle

    The ECU is a Possumlink WRX MY98 & 22B. I'm not near the car at the moment so I can't get additional info.

    Having connected a wideband gauge and logger I was surprised to see an AFR of 11 on tick over with a professional map Everything works fine but I'd improve the idle performance and fuel consumption.

    Currently the ECU is set for open loop.

    Hi,

    I have a 98 GC8 impreza JDM  , in 2001 I had a G1 link ECU fitted and mapped. It's been perfect. Recently I fitted a wideband oxygen sensor with AFR gauge and wideband and simulAted narrow band outputs.

    The ECU does nearly everything I want but there are two areas I'd like to improve:

    1. Close loop on idle - can the ECU support this modification

    2. Wideband support - I guess I would have to replace the existing narrowband sensor with the simulated wideband signal?

    And lastly a question about Knock, my knock performance looks ok, but what does the ECU do when the knock threshold is exceeded?

    Many thanks 

    Carl
