The CTP and CXP were only made in 2007 and had a pre-DPF MP-7engine. They used a EGR mass flow just like the ASET AC engine. I would say a block off plate would probably work. All the mass flow sensors on all the CTP's around here haven't worked in years and no derate

Boss man was there at the unveiling, all I got was this pic

SID 77 is brake demand sensors. They are located on the foot valve on the fire wall. Go to Bendix.com and go to document library and type in SD-13-4869 and choose troubleshooting and down load it. Bendix and Eaton are great about public access to all their manuals . Also RH Sheppard steering gears too!

Disregard what I said about the rocker arm, that only applied if it was a FMI-7 . The FMI-5 you have means open circuit so chances are harness/harness end or injector

This thin 7/8" Bonney brand wrench works great on water lines on the early 7th injectors. I bought a snap on one befor I realized I had this one in my grandfathers old tool box, I use it weekly

Could be harness , injector or rocker arm. Cant find the Bulletin on the rocker arm causing the issue. I just remember it was for the non-DPF MP-7 engine only. Ill keep looking. injector Harness end connectors.pdf

Might be last day of boating season for us however next weekend looks promising. Hurricane Irma is gonna dump some much needed rain here and raise the lake levels up some. I hope to squeeze one more weekend out! When your making monthly boat payments , it's hard to put it up for the winter.

It's standard procedure here to update the software in the engine ECM, DEF/SCR ECM and dash cluster when engine and emissions fault codes are logged. Lots of times the new software solves existing issues and can prevent future issues. I have never see theses updates cause low power complaints. However, there are two possible ways things can go wrong with software downloads and I have done them both. First. Make sure TechTool is restarted for truck it's plugged up to. A couple of times I didn't close out the job card I was on and went and plugged it into a different truck. TechTool thought i was still plugged into first truck and if I were to do any programming, the data from the first truck could have been put into the second truck. The other way (and this happened the other day), all the ECM's in the truck are programmed with the VIN of the truck they originally came from. If the dash cluster , Vecu , engine ecm or DEF/SCR ecm were swapped from another truck, the VIN's won't match. This shows up when you first plug up to TechTool as Mis-matched hardware. You then have to choose which VIN you want to choose, of course you pick the one on the door. If you choose the other VIN , your truck now get programmed as that truck. In these cases your 505 truck could be programmed to 415 . Dealer should be able to go to "product information " in TechTool and confirm HP and that all Vins in ECM's match what's on the door. That said , we sold a 505 hp CHU to a customer and he used it for a week and loved it. Next week he comes in and says it has no power. We test drive and confirm it. Long story short , we install new turbo and injectors and EGR valve. Still no better. Come to find out , owner changes tires and wheels to full size 24.5" and didn't tell us. It threw the computer off so bad it killed the power. Changed the revs per mile in ecm and all good .

I do lots of ECM programing at a dealership. Tell me what ya got

lol not really, it's usually packed tight and you gotta be real close to see anything. Here's my tri-toon with wife and friends

Us and 4 other boats took a boat trip to a bar on the water and ate lunch then back to our usual hangout beach. Hopefully upgrading to a bigger boat next year. Going from a 21' to a 22-23' but the big difference will be going from a 150hp to a 250-300HP outboard. There are tri-toons here with twin 450 HP outboards on them. Small monthly payments! Lol

Nice day on the lake, sadly TVA is dropping the water to winter levels by next week so we only got maybe 3 weeks left of boating here, however today was a good day regardless. Lots for food , drink and scenery! By the way. Every pic I post I actually take . It was a very good day

Should be a "netural start relay" that lets the starter circuit work when in netural. Im thinking its mounted by its self down by the VECU in the kick panel under the fuse panel but not sure. Very few Allisons in CV's around here

I think it will still work but no updates. I think its $200 a year.

However is your harness is not flaking apart like most then you can replace the ends Harness injector terminals.pdf

Being a 2008 and if the engine wiring harness is original, replace the engine harness.

I got some but not really wanting to put thoses on here! Lol

A good crowd at our hangout spot for a Monday

My oldest is out in his bass boat somewhere, he's the fisherman of the group. I have different priorities, good friends,drink sand and sun, and best of all no work/worries

4 days of this has about wore me out. Waiting on eclipse to happen.

Did the dealership reflash or replace the engine ECM when they did the overhaul/replacement? If not you should be still at 460XT. No hardware difference in 460 and 460XT, only the software is different. If you had a power loss after the work was done maybe the incorrect turbo or injectors were installed or boost pressure leaks or incorrect valve adjustments.

Mack/Volvo has their own code reader/diagnostic program. It started out as VCADS and now called Premium Tech Tool. On Volvos and Macks with Cummings engines you must use Insite for engine and emissions repair. Starting in 2008 all the diagnostic repair info is loaded on VCADS/Tech Tool. There are no books anymore on troubleshooting. There is a engine repair manual for the 2008 emissions MP engine but for the 2010 emissions year and after it's all in Tech Tool/ Impact. Tech Tool will work all the way back to 1992 VMAC 1 engines but is super slow.

Every American citizen has first amendment rights whether you or I agree with what they are saying or not. While I don't agree with anything the white supremacist/ Nazi people believe, this is still their right to do their march or whatever they were doing and say what they wanted to say, like it or not that's their right just like it would be for me or you. The problem arises when someone tries to stop someone from exercising their first amendment rights. I don't like cats in my house, so if I get permits and hold a march/rally for "No cats in the house" is it ok for the opposition to show up and throw water bottles of urine at my group and try to shut us down? Freedom of speech is a right even if you don't like what someone is saying. I despise the white supremacist people but they can have their march one weekend and the opposing group can have their march the next weekend. Problem solved. When you try to shut down one groups beliefs it only makes them stronger. Sorry the girl got killed but if the nazis had their little march and a few hundred people showed up and they did their thing and went home. No one would even remember it happened . The next weekend the anifta/blm could have their march and all ok. Probably no one would remember it either. I guess some people can't grasp the concept of free speech....
