HD Mechanic 07 Posted July 21, 2022 Share Posted July 21, 2022 I’m currently working on a late 2006 build date Mack E7. My friend thinks it’s a snail down low. It’s nothing like his turned up R models. The previous owner supposedly had a guy program it without any luck. Now I’m tasked with giving it a shot. Are there any other recommendations as far as maybe another Borg Warner turbo, injectors or a better tuner/program for this engine? It has egr, but no other emissions equipment. It also has a 13 speed and presently I haven’t checked on the rears yet. Any help would be greatly appreciated!

Joey Mack Posted July 21, 2022 Share Posted July 21, 2022 its an ASET-IEGR... is it just slow to pull? I bet it has the power to get it done... and with a 13 spd, I dont see how it could be weak.. My guess it has 442:1 Mack rears. Has some one messed with the EECU programming? Macks are slow and deliberate... but they will pull hard... lets see what the other guy's say... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-503653 Share on other sites More sharing options...

HD Mechanic 07 Posted July 21, 2022 Author Share Posted July 21, 2022 Thank you guys for all the replies. It's really slow to get up to speed even with a 13 speed. It was a lower hp engine and was supposedly "turned" up or programmed to around 460-475. I had always heard that Mack put different size turbos/injectors on them depending on the original setting. Maybe the turbo needs changing or the fuel table adjusted down low? Mackpro it's a CHN613 model and the last 6 are 003660.

67RModel Posted July 21, 2022 Share Posted July 21, 2022 A 2006 is an ASET engine. From my experience running stock AI versions (internally cooled egr) they have zero lugging ability and almost no "pulling ability" (torque) below say 1300 rpm. When loaded you almost have to wind them up to 2100 rpm so you can catch the next gear above 1300-1400. Otherwise your foot is trying to push through the floor of the cab and seemingly nothing is happening for a really long time. Any type of hilly or mountainous terrain obviously compounds the problem. IMO not really Mack's (Volvo by that point) finest hour and really an undesirable engine. Although the AI versions were pretty reliable for the time of early emissions regulations. Who knows what the "programmer" did to this one though. Always a crapshoot with that....... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-503735 Share on other sites More sharing options...
HD Mechanic 07 Posted July 21, 2022 Author Share Posted July 21, 2022 67RModel...I'm with you on how sluggish it is. Hopefully, I can have Mackpro look at the programming. I also think a better s400 turbo would help it.

Onyx610 Posted July 21, 2022 Share Posted July 21, 2022 Did that on one recently, little better throttle response and low end get up. Smokes more too so I know she’s really clearing her throat on every exhale now.

Mackpro Posted July 22, 2022 Share Posted July 22, 2022 After some research it’s a ASET AC-460E engine. Software updates were done a couple of years ago. The engine software was updated to the newest level but the VECU was updated to Step 12A which is OK but they should have bumped it to Step12B to get their money’s worth. Step12B has been out since 2007-2008. Of fuel pressure and boost pressures are good. Getting a dealership to install the 460P HP program might be worth it. If Mack Corporate will turn it on that is .

Joey Mack Posted July 22, 2022 Share Posted July 22, 2022 I deleted my post because I miss-understood the info.. its an ASET-C... I hate them,,, they are SH!T... Mackpro will be the best for this since he is current on todays info.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-503792 Share on other sites More sharing options...
Mackpro Posted July 22, 2022 Share Posted July 22, 2022 To really look into the ASET-AC engine you almost have to have the old VMAC 3 diagnostic program and get into the advanced diag screen where you can view the EGR actual flow and target flow, the turbo wheel speed, boost pressure ( running and key on/ engine off readings) throttle % and engine load . Of course a million other things to look at on those engines. Rocker arm hold down bolts , valve adjustment, turbo calibration, fuel pressure, boost pressure relief valve worn out. One day I need to write all this down . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-503802 Share on other sites More sharing options...

HD Mechanic 07 Posted July 26, 2022 Author Share Posted July 26, 2022 Thank you everyone for the help. I actually started searching for the Vmac III software and got it downloaded for free. There were no catches and it was honestly free. Pm me for the info on where to get it. I'm going to try it on the truck today to see what info I can pull out of it. I'll update everyone tomorrow.

Mackpro Posted July 26, 2022 Share Posted July 26, 2022 The VMAC 3 software diag is awesome. I used the Nexiq USB link 2 interface with good luck and now use the Noregon DLA 2.0 adapter mostly. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-504416 Share on other sites More sharing options...
Joey Mack Posted July 26, 2022 Share Posted July 26, 2022 (edited) Sometimes, I wish that I bought a loaded laptop with V-Mac/DEDEC... but at $10,000.00 I was not able to do it, and that's when I bought my service truck for $8000.00.. too bad...

Mackpro Posted August 2, 2022 Share Posted August 2, 2022 To me it does. I also have access to the VOCOM 1 and 2 which I have to use with TechTool because if I’m not using VOCOM it limits some tests and programing. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70146-2007-mack-e7-performance/#findComment-505157 Share on other sites More sharing options...
