Flap setting in ECU

[InsBro]

Hi all

I had the hot air all the time problem in my Tamora from the windscreen and footwell vents.
I checked the setting as advised on here and it was set to Zero so I changed it.

When I then went back to the main menu you can hear the flap moving. It seems it just blocks off the hot air source and blows the cold air out through the cockpit vents.

Has anyons seen a drawing of the system?

The reason I ask is if you put the value at say 32 would the flap just hit a stop and be the same as 16 or would it direct air through all 6 vents?

Obviously I dont just want to try it and see what happens incase it damages the servo.

Any ideas?

In the setup go to menu 8 and check the flap value, if it is zero then that is why you have hol air all the time. (16 is the rec value)

Changing it btw doesnt then give cold air from the screen and footwell vents it just stops it when you turn the temp to cold.

True, but mine sometimes still always blows hot air even on cold. Turning it up to hot, waiting for it to sort itself out and back to cold stops the hot vents. Seems to happen if it was left mid temp after turning off the engine.

I did have a problem at first where there was always hot air but that was down to a diode problem which was fixed.

The number you set determines the number of pulses to return the flap to a dtumn zero point on startup. Zero isn't enough and hence hot air get round it. The recomendation is 16 although it will have hit the stop before 16 and will thus make sure it is at the stop. More could be needed if your stop is in a slightly differnt place but setting 99 say wouln't be any dirfferent to 16 if it's hit the stop. Thats not to say it might reck the sevro unit though.

So just to clarify the number represents pulses towards a physical stop to reset the flap to a known datumn at startup. It doesn't represent a position thus once it has hit the stop the number from then on doesn't make a difference.

Hope that helps and is understandable.
