New Arduino-based FMTV CTIS controller ROCKS!

Sorry have not been able to fix video orientation quite yet.

Pretty slick! Would love to hear updates as you use it

CID are the 3 air valves on the CTIS system:
C = Control: it's needed to close the quick release valves and get the system under pressure
I = Inflate: opens the inflate valve to rise the pressure
D = Deflate: opens the deflate valve to lower the pressure.

I show it on the display to check the status of the ECU, to know what's going on...

Are these for sale?

Yes, search for PLASA on SS. You will love this thing!

Nicely included is a data cable which allows you to totally customize your own program.

I can attest to the quality of this product, and Christian was very responsive in helping me to troubleshoot my truck once I installed it

 

[Plasa]

Thank you Sir!

I got one of the first batch and is still working great.

With this controller, is it able to control individual axle pressures?

I don't think so, but why would you want to?

No, it's not possible because the entire pneumatic system is not able to check ad fill / deflate per axle. And there is only 1 pressure transducer for the entire system.

Thank you sir! I'm happy that it works as expected. Mine also works now for 2 years without problems. Sometimes if I go over 1500 m sea level the wet tank sensor does not close and the CTIS thinks there's not enough pressure in the tank. Solution is to deactivate the wet tank pressure check by pressing back / forward button together.

I don't think so, but why would you want to?

one axle weighs in at 11k, the other 2 are at 16k, it would have been nice to have the rear inflate higher than the front

Ok, thank you

If you want to use a connector that will plug into the CTIS connector there are some on the big "e" auction site. Just look up

Hmmm I wonder about handling characteristics, operating at different pressures. It would be an interesting experiment though.

 

[Reworked LMTV]

Well, I think I figured out (at least in part) why my rear 4 tires don't dump air. This fitting shows that the 3/8" 3 way T was ripped off the inside of the passenger side frame rail. How that happened, I have no idea. New bulk head fitting ordered through Amazon.

different pressures in axles would NOT be good for transmission in AWD. Different pressures would mean different ratios in each axle due to different tire diameters. wellll...... maybe???

as you mention each end of truck is heavier.... if the heaviest end squats tires on that axle more than other axle result is... your actually at different diameters even if same air pressure. so might well be individual control per axle used to produce same tire diameters front and rear.... might actually be better... hmmmm
