wrenching4life Posted July 21, 2015 Share Posted July 21, 2015 Hey all, as the topic lists i have a 2004 granite that is the most gutless wonder iv ever driven. cant get out of its own way until 1600-1800 rpm then pulls like a freight train. iv read a few things on this topic and iv called the dealer about a reflash and such. They say there is no such thing for that truck. Has anyone had this problem? any luck getting it fixed? chime in id really like to make it the 460 it should be!

wheeler73 Posted July 22, 2015 Share Posted July 22, 2015 The dealer can check to see if the truck has step 12B programming upgrade. If not they can have it turned on and reflash and reprogram and they can check if the engine module has any updates also. The 12B programming does help with acceleration power. Also check boost and fuel pressure. Quote Link to comment Share on other sites More sharing options...
mm826 Posted July 26, 2015 Share Posted July 26, 2015 Sounds like a 18-speed tranny would work well w/those rpms. Quote Link to comment Share on other sites More sharing options...
wrenching4life Posted July 29, 2015 Author Share Posted July 29, 2015 The dealer insists that there is no such update and they told me to check the power relays, apparently those will cause low power so they say, any more thoughts? Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted July 30, 2015 Share Posted July 30, 2015 Sounds like your dealer does not know how to check the programming. I still do the 12B programming from time to time as we see less of the E-Tech and ASET engines. If you can give me the last 6 of the vin and if it is a CV or a CT model I can let you know. It may take me a day or two. Quote Link to comment Share on other sites More sharing options...

wheeler73 Posted July 31, 2015 Share Posted July 31, 2015 You are at Step 9B. The dealer will need to call Mack tech support and have them turn it on. Also they can have tech support check if there are any updates to the EECU. If they won't I can have it done but your local dealer will have to do the programming.

rsb502 Posted August 3, 2015 Share Posted August 3, 2015 The step 12B update helps a lot, if your "dealer" doesn't know about it they aren't a Mack dealer or that guy is new. I found out playing with my 04 427 that if you ease into the throttle then back off and go back into it you'll almost eliminate the smoke limiting de fuel at takeoff because you already show positive manifold pressure. There are some programs out there that will make em run, trouble is getting them to do it as engineering is hard to come off the programs.

david wild Posted August 4, 2015 Share Posted August 4, 2015 Did you call Rochester Injection ??? the man there say's he can make AI engines run as good as any pre sh-t engine, but then again we don't much stuff with weight so we might not know(not really) last year we crossed the scale in MN. @ 414,000lbs with our 460 Mack, it runs great, dealer will only do what Mack will allow, that is why guys like Bruce Mallison (Pittsburgh power) and others do so well at making things go better, but with more power comes more expense, It costs money to run with the big dogs, if you know what I mean ???

rsb502 Posted August 4, 2015 Share Posted August 4, 2015 Say you had an Etech or aset AI engine, now say you wanted more power with OEM parts. Just for the sake of argument maybe put some 427 injectors, an advanced cam key, a 460xt turbo together with a 355-380 maxicruise ecm........ I'm not saying its wood shattering but hey over 500hp to the ground ain't bad!

wheeler73 Posted August 5, 2015 Share Posted August 5, 2015 Hey Waterwagon you are at step 12A. Your dealer should be able to do 12B programming. Also have them check for any updated EECU software and data files. Quote Link to comment Share on other sites More sharing options...
Waterwagon Posted August 5, 2015 Share Posted August 5, 2015 What issues did that update address do u know? Quote Link to comment Share on other sites More sharing options...
wrenching4life Posted August 5, 2015 Author Share Posted August 5, 2015 Well my dealer like before knows nothing about any updates or anything... The said calling mack tech will do nothing and seens how mack and volvo are one of the same the guy said, the days of tuning and updating are long gone.... This is so frustrating all I want is a 460 horse truck to be a 460horse... I mean I'd take more but heck it feels like a wooping 150hp Quote Link to comment Share on other sites More sharing options...
felicello122 Posted August 5, 2015 Share Posted August 5, 2015 Does the 12b program apply to the etech 400 hp motor,2000 year model Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted August 5, 2015 Share Posted August 5, 2015 FELICELLO122 I will need the vin to see where you are at. It is possible but I am not 100% sure. Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted August 5, 2015 Share Posted August 5, 2015 wrenching4life you need to find another dealer. Sounds like yours does not know how to do much with VMAC III. I just did one yesterday and had tech support turn on a data file for the EECU. Where are you located? Quote Link to comment Share on other sites More sharing options...
wrenching4life Posted August 18, 2015 Author Share Posted August 18, 2015 I'm located in Somers CT, I really appreciate all the help on this one! Quote Link to comment Share on other sites More sharing options...

Refined Trucker Posted August 20, 2015 Share Posted August 20, 2015 Wheeler73 I'm going to jump on the band wagon here and ask if you will check mine also. 01 cx613 #520010. Thanks for the help. As with these other guys my dealer's guru was probably just outa diapers when this truck was built. He don't seem to know much about vmacIII.
