Radiator fan connected to Aux output 7. Temperature on set to 92 degree C, hysteresis 4 degree, polarity low. Car powered Ign. swith pos 2, engine not running, fan is off. When changing polarity to high fan goes on but is set to low. When powering down the ECU the fan goes on... This would suggest the ECU is driving to ground when power is off, this isn't the way it should behave is it?

Setting an output frequency per ECT temperature step in range like discussed in this thread, http://www.linkecu.com/forum/forums/lem/271344851 Thanks.

I was afraid fro a reply like that.. But thanks anyway!

17Hz is high temp (Max) 18-19 Hz is 3/4 high 20-23 Hz = middle = target 23-30 Hz steps to minimum temp. Doesn't respond to DC settings.

Does the new firmware 1.7 change anything for this? Concerning both the Linkplus G2 and Linkplus G3 btw... And, although late, thanks for the reply. Unfortunately I didn't test the mentioned setup yet...

Just a warning.. Trigger 2 and Knock 2 were mixed in the loom..

I'm using a LinkPlus G2 in my Volvo 850 5 cylinder. The factory management system used to be a Bosch LH 3.2/EZ 129K system. The engine temperature is measured by the management and converted to a modulated frequency signal to drive the temperature gauge in the Yazaki or VDO dash. Is there a way to replicate this setup with the linkplus G2 so I can use the temperature gauge in the factory dash?

You =Just, sorry..

You wanted to inform that I have the car up and running. Volvo 850 2.5 ltr 5 cylinder with throttle bodies. Car is running like a charm, engine responds to ECU changes very well. Overall I'm impressed. The one thing missing, closed loop lambda control preferable from a wideband. (LC-1 in this case.) Regards, Johann

Thanks Ashley.

How do I wire a Volvo 850 coil to a linkplus G2? And do I need the supressor? A wiring diagram of the stock volvo connection can be found here, http://www.swededemon.com/images/SDM/shots/engine/ecudiagram.jpg
