    All the new trucks with the new Anthem style dash (includes the GR series) now have the dreaded LCM ( light control module) that’s was brought over from Volvo. This further complicates the usual simple troubleshooting of lightning issues you might have . I have not tore into the dash but there’s a good possibility the DRL override harness is already there.

    96 Vmac 2 ecm

    It’s a kit from Mack that converts only certain VMAC 1 ( 2 Ecm’s) trucks to VMAC 2 ( 1 Ecm) . I’ll see if I can find the bulletin.
  3. We had several bad reman injectors that caused a similar issue. Truck would start and run fine for about 2 seconds and die. On a few we saw fuel in the oil , some we didn’t . We put 60 psi air pressure into the the fuel galley in the side of the head and capped off the pressure relief valve. Sprayed the injector plungers and body down with soapy water. We also bumped the engine over and re-checked with plungers up and down. This was on non common rail engines though. What’s last 6 of vin and model

    I definitely agree in your situation. We have one new Anthem at our plant and when I plugged into it to set up road speeds and PTO settings , there was almost 600 different changeable parameters . And they are not usually in any particular order so it might take a little while to search through and find it .
  5. Quick question, on the expansion tank on top of your radiator. On the drivers side of it, is the pressure cap on it blue or black? The problems ones were blue, the updated ones are black. I got the service bulletin but I cant post it here due to size but will PM you .

    This feature can be turned off in parameters with Tech Tool. I see it as a safety feature and like it however some people don't. I wish it was mandatory on cars as I've had several close calls during heavy rain storms and low visibility where people fly down the interstate with no headlights on.

    more ponies

    Being you have a ASET AC 380/410 HP, you already have the same turbo as the 460P engines. If you have a good local Mack dealer that does HP conversions , all you need is the 460 injectors and the factory 460P download. But , if your 380/410 is running correctly you should have 1660 FT LBS of torque and around 23-31 psi of boost pressure under a hard pull. The 460p has the same 1660 torque but 483 HP and around 33 or more PSI of boost.
  8. There is a service bulletin on coolant push on early MP engines. It might take me a day to find it though

    How to test eup pump

    Did you pull the cam roller for the #6 EUP and check if for flat spots. Any smoke from exhaust? If so I’d remove #6 injector and loosen the rear rocker arm shaft allowing the valves to close and using a rubber tipped blow gun. Blow air into the #6 cylinder and listen for air coming out intake , exhaust and crank case. That way your ruling out compression issues.
  10. The AI engine came in the 2004-2007 CV, CT, LE, MR and a few of the last RD’s. It was basically a CCRS ETECH with a restrictive exhaust manifold and different camshaft and turbo and injectors. The camshaft has 2 bumps on the exhaust lobe so as the piston is comeing down the exhaust valve opens again and sucks dirty exhaust back into the cylinder to be burned again. They went this route on the vocational trucks. On the road tractors they used the AC engine which had a traditional camshaft but has a EGR valve and EGR cooler. The AI engine was reliable but not very powerful and the AC had better power but EGR coolers and the VGT turbos were it’s downfall in some cases.

    Automated Manual Transmissions

    I always hated working on a MP engine with a Allison trans. All the extra coolant piping going back to the Allison heat exchanger got in the way and made hard jobs harder. The clutch’s on the M-drive seemed to last along time around here , but not a lot of stop and go traffic here. I remember us only changing 3 M-drive clutches and they were all the same customer. He was using CHU’s in a muddy landfill. This was before the HD M-Drive came out. That said around here in the dump truck application the Allison is the winner .

    96 Vmac 2 ecm

    A VMAC 2 ecm will only fit a VMAC 2. However there’s a jumper harness kit for certain VMAC 1 trucks to use the VMAC 2 ecm. VMAC 2 ecm part numbers start with a 12ms59m, m2, m3, m4, m5, m6, m7, m8, m9, m10, m11 and reman m11x
  13. Looking at the Mack reman booklet . It’s seems there are only 2 injector part numbers for the CCRS engine . Below 460 HP which are 700cc injectors and then the 460 injectors which are 850cc. Sounds to me the 460 injectors are dumping quite abut more fuel. Unsure of anything Rochester but I did speak to them years ago and they knew their stuff.

    Automated Manual Transmissions

    Only issue we had with the GU’s with Allisons was that the Allison needs lots of cooling and GU radiator is not big enough for 505HP with the Allison. Max HP is 445/455
  15. It was a factory download. This was back in 2010 when Mack could/would actually do a little tweaking of the files. I saved the actual emails for future use . If you use that vin you will get that actual data file
