    New M1088 Owner

    oh active duty? You should have access to the good stuff!! The military version of Cat ET doesn’t even check in with Caterpillar!

    on the subject of checking codes, there are some fair deals on eBay right now for the serial ICE kit. If you get one with the DPA3 in it you can read engine codes with CAT ET and reprogram the CTIS with the Dana software. Should be able to talk to the ABS unit and trans with the right software...

    New Ride

    Not sure what a runflat is but I have had 7 of these tires apart now and none had anything other than the inner beadlock in them. The rims looked to have never been disassembled, paint was completely unmolested on the beadlock threads, among other signs they came that way from the factory.

    New Ride

    To echo what others have said about the tires; my original 2003 rubber looked pretty good to me. Took the truck to the sand one time and all the polishing action on the sidewalls made the tires look darn near new to me. I felt pretty good about them, but on another trip to the coast I noticed a...

    Like I said, I was trying to keep the pictures small. The full schematic is available for download if someone wants it, as you can see from the snip, Clutch is wired to PTO input further down the harness. ECM must use the clutch input for some part of its PTO programming.

    What Cat Lists for those pins matches what the S&S schematic says. Which pin number were you suspecting was wired to +12 because I don't see any other pins wired to power in the schematic, they are all inputs and outputs.

    I just snipped out the connector part of the schematic to keep the picture small, but if you trace those all the way out they all end up at either +24 BATT or +24 Ignition(via circuit breakers). I will also use a volt meter at the truck connecter when I disconnect it for the bench flash just to...

    Just circling back on this point, according to the A1 schematic, the ECM is fed with 24v. I am assuming you were successful doing it with 12v and that is what I will try first, but this is interesting.

    yeah seriously…. Just an update, because I didn’t follow advice from @fuzzytoaster my truck is out of commission until a bench flashing harness arrives from Australia. Trying to flash the ECM through the vehicle harness is a BAD IDEA. ECM thinks it is blank and of-course I am now crank no-start...

    I believe that I successfully backed all of that up before the flash attempt. Did you remove your ECM from the truck when you used the 70pin cable? To confirm what you said above, the ECM needs 12V? not 24?

    DG Technologies Protocol Adapter (DPA 4 Plus)

    I have been borrowing a buddies adapter, but would like to get my own. Wondering if anybody on the forum has a known good one used that they would like to sell. This is a Dearborn Protocol Adaptor. It seems that the 4 Plus has been superseded, but I would like to stick with the DPA4+ for driver...

    I figured I'd give it a shot and SURE ENOUGH, exactly what you said would happen, happened. Imangine that. Now CAT ET basically believes the ECM is blank, however it won't even try to flash now, it bombs out with an error code 98304 "The ECM is not responding to the service tool" Once I have...

    This is great info, I was playing around in ET and it mentioned taking an "ECU Replacement" file. Now that makes sense based on what you are saying, I will be sure to pull that immediately just so I have it on hand in-case my ECU ever croaks.

    This was the "Gotcha" I was afraid of. So there is no way to flash via the kick panel? Can you provide some information on the 70 pin cable? Is it easily available? Do you want to sell yours? Thanks for the info!

    2003 M1078A1 3126B 330 horsepower flash

    I would like to get a little more juice out of my engine while climbing grades. Is it really as simple as flashing the ECU with a 5 Ton flash file? I have seen a few threads where people have mentioned having that done in concert with a gear change, but I haven’t found it explicitly stated and I...
