  1. loosen the clamps and rotate them if possible.
  2. agreed on the jakes. and more parts to wear and replace for less effective engine braking.
  3. correct, but the ECM only knows what the gearbox output speed sensor tells it, so modifying it's "pulse" to be slower than the standard 16 or 14 tooth pulse wheel at normal operation will allow you to trick it. using a gps for true speed after that is all you need.
  4. engine wiring harness too. check for oil at your EECU. oil goes through plug cause it's in a bad place and travels to computer.
  5. do u do head tension .to 220ft/lbs. we had Mack instruction to do 205ft then re-tension after road test. now it's just 220ft at last pull. power leash is a good easy setup after you've done a few.
  6. Timmy b. love some info bro. cheers.
  7. definitely driveline related? I reckon engine flutter, we had a really bad run of injector tubes/orings on mp8s in Australia. if you make it really lug, make it flutter/vibrate as much as possible, the loosen off your fuel filter. if the fuel squirts out, its orings... combustion in fuel system. however, usually comes with hard starting.
  8. I have all vmac 1, 2, 3 and 4 fault codes if anyone is interested. also Alison trans and eaton auto shift trans codes, including freight liner paddle shift. pm me. cheers.
  9. nice work, if you want a copy of the fault codes I can email them to ya.
  10. longy82@hotmail.com. I can scan the info and send it.
  11. 6-4 is a link 1939 fault.check power your ecu from the fuse on the firewall panel(outside) the must be 3 power at the j2 engine ecu plug. pins 10 22 and 41.
  12. what side is your ecu on, exhaust or inlet side.
  13. dammit, so no US made aftermarket software. bugger
