    Intercooler Pump Control

    The major M157/M278 mail-order tunes include adjusted intercooler pump operation (lower setpoint temp), but this isn't available in VCM Editor. This would be a great feature for MB biturbo engines as they're prone to heat soak even at stock boost levels. Can we get aux pump control added to HPT?

    Bump... does anyone know the table number for this? I tried to log the low temp coolant temperature and pump speed, but got no data. Currently it seems the pump is activated partially by throttle and I'd like to simply run the pump based on IAT, regardless of throttle.

    i have looked at damos,it have a temp activation..you would need to start it very early to get benefit.

    Log a ticket with HPTuners. I don't think they read these forums.

    I did that, but was told they need the table number to add it.

    That's the same lazy response I got about cruise AFR. Not good enough considering we pay EIGHT vehicle credits for our vehicles. More effort in to continued development needs to be made. If it was 2 vehicle credits, I would accept that type of response but NOT when we pay 8.

    The table number must be something specific to the DAMOS that HPTuners use. They should NOT need a "table number" if they actually made an effort to look for the table. Very disappointing.

    Run Switch with relay to the pump on key on or on a switch you can control. Much Easier done many times. Also if its an earlier year separate the cooling systems. Hope that helps

    There are hundreds of maps. Support has been helpful even for myself to mention the same. If I know the table location I could specify and they will add as an available map. You can use a tool like WinOLS to identify a table and provide that to support for addition.

    Do you happen to know the map location that would help HPT add it?

    3EE392 => Upper Threshold IAT for Activation intercooling pump

    3EE394 => Lower Threshold IAT for Activation intercooling pump

    3EE3A4 => Upper Threshold Transmission oil temp for Activation intercooling pump

    3EE3A6 => Lower Threshold Transmission oil temp for Activation intercooling pump

    3EE3B9 => Intercooler Efficency (IAT)

    Thanks! I'll see what they say..

    I noticed that my IATs don't drop unless I'm on the throttle somewhat, regardless of IAT at the time. It seems like there may be a throttle or load component activating the pump.

    Easier is to just to make it always pumping by making the intercooler pump directly connected to the switch ON position.

    The tables have been added to the latest beta of VCM Editor. I'm playing with them but haven't seen much difference. IAT still only drops with throttle input while in gear... so maybe a certain minimum load %. Are there any tables you can see that sound like what I'm describing?

    I think the transmission oil temps are separate and meant for a transmission cooler pump activation.. but they have been added either way.

    I connect the Intercooler pump directly to the fuse box so its always on when the switch is in ON position.
    That's the best way in my opinion
