  1. Hey Joey, I'm curious what tools do I need to change the governor setting from Min-Max to All Speed? What's the difference between the two settings?
  2. I'm running one of these as well, from a factory 400 the maximum setting is definitely noticable but not significant. The blixxton module seems to help with maximum fuel rack position rather than quicker response.
  3. How would I go about doing that?
  4. Is there anything that can be done to improve the throttle response on a VMAC2 engine? The truck has tons of power but it just seems like it takes a long time to build boost as compared to other engines I've ran. I know mack programmed these engines so they wouldn't smoke but I was just curious to know if there's anything that can be done to open up the throttle sooner?
  5. From what I have studied and have been told the production years of the VMAC Generations are as follows: VMAC I - 1991-1995 ( These models had 2 ECMS, a vehicle control module and a FIC module) VMAC II - 1996-1997 ( This model was basically the VMAC 1 but streamlines into 1 ECM) VMAC III - 1998-2003 (E-TECH Unit Injector Engine) VMACIV - 2004-2007ish? Up until 1997 a full mechanical E7 was still available upon special order I believe. Somebody please correct me if I am wrong. Vmac3 has a good explanation of this in one of my posts here:
  6. Upon inspection I found the plastic water trap in front of the cab is cracked. If water gets around this can it end up in the cab? I attached a picture
  7. Hey fellas, after a day or two of some heavy rain in Southern Illinois I went out to move my CH around the yard and found an uncomfortable amount of moisture in the passenger floorboard. No puddles of water on the floorboard but it is definitely soaked on the passenger side. It seems to be wet in the very front right corner of the truck as well near the firewall. This has me pretty concerned since the VMACII module is mounted right in front of the passenger seat on the firewall. Without doing any extensive searching it looks like the only place the water could be coming in from is the door seal on the passenger side. Is there any place else on these old CH cabs that were common for leaking? Thanks in advance
  8. What's the difference between the EM7 engines verses the straight E7 engines? I thought the EM7 designated that it was a mechanical engine (hence the "M") but our mechanical engine tag says it's a straight E7. What is the EM7 engine?
  9. I have never ran an Eaton 18-Spd and have always wondered how they perform compared to the Mack 18-Spds. Are their designs similar? Which ones last longer? Is one more heavy duty over the other? Which one do you like better? Also, could someone explain how the T318 and 2180 transmissions differ?
  10. I have heard rumors that the Mack T2130 transmissions are the same transmissions as the T2180's and that you can convert a 13-Speed Mack to a 18-Speed just by changing the shift knob in the cab. Is there any truth to this?
  11. Thank You very much VMAC3! I have been searching for this exact information for a week and nowhere on the web can I find any literature or history on the E7 engine. I have just purchased a 1997 CH613 Gold Dog Mack with the E7-400, T2130 13-SPD, and 3.78 Mack rears. The truck has 425,000 original miles. I believe that the engine is a VMAC2 but I have not ran the VIN or engine serial number to verify that yet. It is by far one of the nicest 23 year old trucks I have ever seen. I should preface this with we have owned a 1996 CH613 with the Full Mechanical E7 for over 20 years now. It has been turned up quite a bit and it will run circles around our 450HP Cat 3406E's. This 1997 Mack that I just bought will be our first Mack with any electronics on it. I was somewhat familiar with the VMAC3 engines but was totally unaware that Mack actually produced an E7 with a electronically controlled In-Line Bosch Pump until recently.
  12. Can someone please give me somewhat of a detailed history of the E7? I'm more concerned with the how the fuel system has changed over the years it was produced. (From full mechanical to full electronic controlled)
  13. Can anybody give me somewhat of a detailed history of the E7 engine? I'm more concerned about how the fuel system on the engine changed over time. I'm aware that a full mechanical engine was made and that a ECM controlled engine was made. However I've recently found another model for sale that uses the mechanical fuel injection pump but utilizes what looks like a electronic stepping motor to run the throttle. We have a full mechanical E7 in our fleet and we're convinced that it is the best engine to ever roll off of Macks assembly line. I would just like some history on how the E7 changed over time and what models proved to be the most powerful and service free over time.
