I also heard that the XT file was replaced by the standard file if you tried to reflash ! that there is NOT fact A Rumor and never tried by us as we always recommended to guys to leave it alone unless it was broke! Some of that stuff was propaganda in my mind ( Politics ) Just my opinion Bud!

Nope the ECUs come base HP you have to reflash them with the truck it was born in! That protocol you mention there was some BS thing mack or fuller came up with due to Extra torque ! Utter BS ! Back in the day you could get a Fuller Behind a V8 ! E7 couldn't hold a candle to the torque of a 400 maxidine V8! And the meritor Diffs are tuogh as nails a mack diff these days is a waste over money unless for some reason you need a top loader diff!

Nope the vecu would not like having its mate! If you have both from a doaner truck it may work!

All the Best To everyone here @ Our BMT family! Happy and hopeful new year!

Like wise ! Keep on truckin buddy! One foot in front of the other best you can! And the statement above rings so true!

Come on Barry Buck Up!

THe first year of 2004 of these trucks we sold had 20 in stock sold ten, the other ten became parts trucks for the best part of a year! couldn't keep Turbos on them ! Mack ran out of turbos so we ended up robing trucks to keep guys running ! Manifold studs broke ,coolant push And the imfamous Fuel line Feasco ! The list was long! They finally got a handle on it in 2005 after the damage was already done! F**king Embarrassing if you were a dealer! or a real Mack guy!

Elon Musk will save US! Just ask him!😅

In my opinion VMAC1 IS better than VMAC2 WHY? two separate modules Engine ECU Vehicle ECU in Vmac one , Vmac 2 All one module ! Easier to trouble shoot V mac one! Secondly VMAC 2 concept was done only a year or two and they went back to separate modules Thats got to tell you something right there! Just sayin!

stay away from 2004 RUN AWAY ! 2005 up to 2007 sort of OK !these were a disaster first year out But once the bugs were out they were Just OK!

Keep well buddy and make the best of the holidays!

Nope much rather not talk politics Here or anywhere for that mater my self Makes my blood preasure High!🥵 just thankful to BE ABLE TO TRY CHANGE THINGS VOTING DAY! even thou the system sucks! At least you can voice your opinion with out being shot by the government anyway! For the most part! 😇

YUP ! IS it fact or fiction? they are likely forced to get there Vaccine! We have the choice maybe thats why? Duno

Bro ! One thing about it you can vote still . Those folks don't have that luxury !

Some times I think we would be better off not knowing some of the stuff they choose to tell us! this being said this bug seems to be a smart bug It effects everyone just a little differently some not at all !So its now mutating so it can spread faster to get More of the people it can effect! For what ever reason ! Maybe its natures way of try to getting rid of us repairing the world so to speak! 🤪 What pisses me off is If you go to the emergency with even a stomach ache, one would think they would test for this shit! NOPE! they ask you if your Vacxed If you are they wave you on thru ! And don't bother testing for it! Its obvious by now that VAXED OR NOT You can still be packing it in there unknowingly shredding it around ! No real good solution to this situation!

Glad you put this question up buddy ! I was thinking of posting it here but was hesitant due to the anti vax discontentment crowd ! This here is a smart Bug The sumbitch seems intent on getting everyone sick by changing its tactic tic every six months Not sure how to feel about it ! I have a niece got it about the same time you did and she is feeling the sane as you right now!

Glad I didn't set them valves they would have got set at 24 thou! Just cause that's how I always done it may not have looked at the valve cover However if it says 28 then that's a not too tight 24 to me ! Did a set on a 3406 e once, cat provides a min max set 3 or 4 thou one way or the other in my mind is reasonable! I believe there is likely a plus minus factor built in to the spec Mack provides ! Just my opinion!

The steel plug is likly the pointer! some had a pointer pushed in the hole! Just use the center of the plug as your guide you will be fine it really is not rocket science! if you are off a little one side or the other on the Valve set marks It will likely not effect the Valve set that much! just follow the directions as jojo posted you'll be fine.

Thanks for posting this First look for me!👍 Our DOT people would likely put the truck out of service for having that obstruction on the glass That's how dense they are here!

There should be a pointer in the engine housing The marks Valve set and TDC on the flywheel

Even thou I am Mack Guy If owned a truck I would go Fuller 18 for the very reason stated above PARTS! You can repair /rebuild a fuller for 1/2 the price of the Mack trans! The only draw back is you need to find a Mack bell housing because of the mounts and the clutch shaft arrangements ! The 12 speed is the best dump trans as stated not viable for the reasons stated! Just me!

Strange But Nice! Your getting the boost of a stock 427 a little under a 460 37 - 40 ! Good job! You can bump a thousand for a bit and not hurt anything as long as the boost doesn't start falling off to much !

I never saw one of these either ! never new it existed That said The new online crap wiring diagrams are Almost non existent for the older stuff and even if its there its a Dogs breakfast to look at! Volvo Trashers have totally dropped the ball when it comes to most of this stuff!

Quite honestly Both our countries have the resources to make ALMOST Everything we need right here IN House ! Do we have the fortitude to do it and pay the extra? Duno ! Never been tried we have been to busy subsidizing china! question is ! Are we willing to pay more to have our own people do the things we need!? If we haven't spoiled there asses so bad with all the hand outs!I Will they Do it ? Some of Us will ! I for one believe in helping out (when need) but when people Are to lazy, too spoiled to get out there and get there hands dirty then.............! Fill in the blanks!

Sure ! This all depends on what beer you were drinking last nite as to the recipe you use! May be a fine line there me thinks! 😂
