Hello all. As promised the Arduino sketch for the CTIS controller. The sketch is complete, but the I/O pin's are set on default. This because depends on the wiring (I made a PCB). The sketch is also able to read / write the default pressures of the 4 terrain modes. You need to write the 4...

If you are changing the tire and the CTIS wheel walve will not close after pressure check or inflating, check the banjo screw if there is some dirt. Happen to me yesterday. If the pressure don't fall under 20 psi between wheel valve and banjo screw the membrane do not close... Christian

Hello all! I have a strange problem with the air brake pressure gauges. Pressure is about 120psi on all 3 tanks, CTIS is working well, but the 2 pressure gauges shows front brake 90 psi, and rear brake 120 psi. Does anyone had a same situation? The 2 pressure transducer are near the left front...

Any news for the lockers? Christian

Mine also, registered in Germany. Italy is a nightmare, but I will retry this winter. Christian

Hello! I now build in total 4 and sold 3. If someone need a complete ECU as descibed before I will sell them for 200$ + shipment. Christian

Hello all. Sorry for the late answer, but due heavy work I did not found the time to answer. After 2000 miles I must admit that the Arduino and CTIS do a great job. It works like a sharm, every 15 minutes checks the pressure and adjust it. No problems after all. More problems with broken...

If you don't hear any solenoid clicking means that the system is not ready. Most probably as Ronmar wrote the wet air tank sensor...

Awesome! That's a good tip! Thank you very much! Do you have a picture also of the other side of the hose? Christian

Thank you! That I think is the best way to solve! Do you remember what kind of attachment they had? Jig or flat?

Happened today, 1000km from home. Frame and rear axle is full of oil, what a nightmare! Now I need to find some hydraulic hose shop to get 2 flexible ones... Loose about 2 liter of oil. Of course on weekend, no one is working... BTW: are the original hoses of aluminium or steel? Christian

Hello NDT. Should be the winch gear case full of oil?

Hello again... Anyone knows what item no. 43 do? Thank you and sorry if I insist... :-) Christian

OK, found the drawing. I see a screw (43) and a oring(42). in m1078_TM 9-2320-365-24P.pdf, page 680 Maybe both of then are closing / opening the oil flow to the brake chamber? Christian

Self recovery winch: loosing oil through relief valve Hello all. I have a strange problem with my M1078 self recovering winch. On top of the winch drum (behnid the hydraulic motor) there is a small spring loaded valve. I loose all the time oil from this valve, without operating the winch at...

I have a Webasto ThermalPro 90 water heater. The big advantage of water heater is that you can connect it over a heat exchanger to the coolant system of the engine. I did it due low temperatures in the winter. Preheating the engine 15 minutes eliminates completely the starting issues on cold...

For everyone that want build a new CTIS ECU: Don't forget flyback diodes, it drove me crazy trying out why sometimes the Arduino reset without any reason when shutting off the valves... Seems that no diodes are in the solenoids... Happy hacking! Christian

Hello Forum. Time is running and project is going on. I finish the configuration mode that enable (when you short a contact inside) to manually inflate / deflate the tires and to save the actual pressure as new default pressure for the 4 diffrent modes. I also add a switch to cutoff the power in...

On my truck only the ECU was changed, for sure. All the rest is original and never touched. But anyway, now with the new self made ECU works, and that is the most important thing... Thanks and regards from Italy! Christian

On front of the box is the kitchen and the bathroom... Sorry, I am not as good as Seth for pictures and text... :-) Christian
