They are all potted...Are they potted or can you service the unit?
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
They are all potted...Are they potted or can you service the unit?
Bummer.They are all potted...
If you had a C7 truck then you could flash the CTIS ECU... I wonder if I can do that with someones ECU if I connect it to my truck???Bummer.
I think I read that you said all lights on steady is a corrupted memory. Is the memory Non-volatile or is there a battery for the memory? The reason I am asking is that if there's a battery I would not want to get an older replacement unit. Also is there a decoder for the date on the bottom?
If I am getting an understanding the black ECU can be flashed or at least hooked up to a computer. I have not read anything about the green ECU being able to hook up to a computer. So in theory I guess you could take a black ECU and put it in a C7 truck. I don't know if this can be done with a green ECU.If you had a C7 truck then you could flash the CTIS ECU...

The adaptive values are stored in a RAM chip
PLOT twist. Do you know the number for your ECU? I wonder if a y cable with work????i have a green ECU in my truck and I can do this.
I don't have a Y cable, I have a Dearborn III adaptor that connects to the Deutch connector by the battle kill switch.
It looks like your software is using SAE J1708 protocol? That would explain why pins a and N have 1708... and pins D and A might be SAE J1939? I believe J1708 uses RS485 hardware to receive... Wouldn't think it would be too hard to make an adapter. Where did you get the software? Maybe a way to bench test the ECU? There is really not much info out there on these units.My truck is a M1089a1 and the tire pressure is 81psi. The normal lmtv highway tire pressure is a lot less. I can set the tire pressure for the ECU with my DANA diagnostic software, also the over speed - speed.

Can you screen shot the "info" tab? Is there anything that talks about config or what configurations is set? There are 2 pins that set the config of the unit.To illustrate it I changed the tire pressure from 81.0 to 74.0 and confirmed it. The program writes it to the ECU, which then lowers the pressure. It stays programmed even if I unplug the CTIS and only changes when I change the value with the Dana diagnostic program.
in other words if you have a problem with your CTIS I can not just check the errors but can also change the tire pressure . In case you bought an ECU from a FMTV for instance
Novram no battery.Bummer.

You can make pressure adjustments but if you go too far the system will not function correctly. Valves will not close at high tire pressures in the cold and may not deflate farther then designed.Does the software allow you to make permanent changes to the pressure settings in each mode?
What faults do you suspect would appear??.... Changing a trucks CTIS configuration is not recommended. It could generate faults from altered performance.
Overinflate? Based on what? As in not the 50ish-lb the previous trucks were set for??? But then again.... maybe those were under inflated thus decision to change to the 6x6 settings? How much you suspect the pressure will drop in temps below 50 and wouldn't the ctis adjust as the tires got warm while driving?...Currently all 4x4s from 2006 are incorrectly configured as 6x6 Wreckers, they over inflate and the higher tire pressures will not be maintained below 50 deg.F.
