Hello Coachgo! I verify the pressure and in fact is above 90 psi. Main problem is that the ctis does not work with this pressure, continue to inflate, recycle everytime, pressure test after 30 seconds is always negative, so starts again to inflate. What should be possible is to insert a...

Hello again. Now I am quite sure to found the reason. I gave a look to the ECU and as immagined it's not original. I did the following tests: - deflate to cross country: works well, stops at 60psi and stay stable - deflate to sand: works also, stops at 40psi and stay stable - inflate again to...

Yes, I use shop air to the truck. Today I need to recheck it again. I untighten the banjo skrews, let's see if some tire has diffrent pressure... Thank you very much! Christian

Hello again. I'm now quite sure that the ECU is from a FMTV 5 ton truck. That can explain why the pressure is so high. Are the ECU compatible with the original pressure transducer on the PCU? If I change the pressure transducer on the PCU, makes diffrence? It's possible to change pressure...

Hello all! Thank you for your infos. @coachgo: I have Goodyear MV/T tires, weight is about 19.800 lbs (9000kg). I untighten the banjo skrews and seems no wheel is loosing air. But today I will make the soap water test. I'm quite sure that the ECU is not original, it was replaced from another...

Why not relays? Using some industrial relay is more reliable than PWM, and in emergency can control manually... Christian

Sounds very intresting. Thank you very much for the information! @Ronmar: I will be more than happy if you share some pics and info about your solution. Thank you very much! I would like to have a system like the original ECU, where you can select the ground type, maybe with display to see...

Hello again. Please don't misunderstand me. It's not because it is not working, but I like to have a spare part of this component. On web actually I cannot find any seller that sells the controller. This is why I was thinking to make a rebuild of it. Christian

Hello forum. I am thinking of creating a Arduino hack for the CTIS controller for M1078, first and maybe second generation. I gave a very fast look at the system and seems not really complicated. Does anyone have some information or a workflow diagram, some sensor value or something else that...

OK. Thank you very much for your help! I will try the thin plastic ring and also the alu handles from online market... Thanks a lot from Italy!

Hello. The wood is not very thick, about 3,2mm woos and 5mm foam that can compressed. The original handles have sharp edges and I fear they will cut leater... Welding a pipe on the alu handle can be a solution, I will think about it! Thank you Christian

OK, I will try and let you know... Thank you very much! Christian

Hello Ronmar! Thank you for your reply. Yes, there are spacers between the upper hookplate. Now I need to figure out if it's better dismiss the lower spacers or add some upper spacers too! Many thanks, it helped me a lot! Christian

Hello Suprman. Thank you for your reply. I will try to dismiss the spacers under the 2 lower screws, also for me seems misaligned... Have someone a picture of a correct aligned bracket? Thanks a lot! Christian

Hello forum. Finally I got my M1078 from the dealer and starting the RV conversion. But for first I have a problem with the cab latch. The hydraulic latch is working well (tried it with cab fully raised, it engages and locks the hook), but when I lower the cab the pin would not go in and block...
