I just set up an LB7 owner with a set of SAC 45's to replace his original injectors at something like 280k. I have purchase history back in 2003 Mega filter and FPPF Total Power since new with lift pump soon to follow. When he sent his cores in I marked them specifically so that they could be examined for overall wear condition. I believe they finally gave in to the blue smoke seep common to the VCO nozzle.

In that review you can see that adding performance surprisingly allowed for a lower EGT - sorta contrary to what logic might suggest.

Hi,

OK, the deed is done.

Spent an interesting and informative time with John Kennedy yesterday in his shop, getting a dual lift pump and "Kill P0087" tune loaded. John says he tweaked torque a bit as well.

Time will tell, but I have high hopes.

Hi Davey,

It drove 300 plus miles back home yesterday no problem. The real test won't come until summer, when I start long trips with the heavy trailer. It has never coded running empty.

But I will give a full report for sure.

Hi Jim,

I'd love to visit with you and park it in that pasture up the hill again. But between a wedding in Texas and a bucket list New England tour in the Fall, none of my my travel will be that far west this year.

But Texas heat in early August should be a good test...

Hi,

Time for an update.

A couple months ago, John Kennedy added a dual lift pump and changed the parameters in the ECM regarding the P0087 code. I also installed an Edge Insight CTS2.

I now have two 200 plus mile trips towing my big fiver under my belt -- the last one in 90 degree heat. In local driving, I had one very quick regen at about 450 miles at 37 soot. So far, no codes, towing or otherwise. The new monitor is particularly useful to me for keeping track of things like fuel temperature, which seems to be a factor in throwing the code on high mileage injectors.

Still learning and watching, but I am optimistic. The next big tests will be about 500 miles over into Iowa for July 4th, and then about 1,750 miles to Texas and back in early August. Time will tell...

Good news! And good luck with the longer trips this summer!

Hi,

A one year report on big fifth wheel towing performance with the Kennedy modifications.

The almost 2,000 mile trip towing to Texas in ferocious heat last summer was followed by about 5-600 miles of other miscellaneous towing later in the summer. The code appeared once on a long, very hot pull coming back from Austin, I cleared it, and didn't have any more on that trip.

I just returned from about 1,900 miles towing down and back to the Gulf coast for our winter snowbirding. No 0087 problems at all.

I pronounce it money well spent.

Thanks for keeping us up to date. P0087 has been a problem for lots of folks.

Default JK tune solution sounds good

Hi Rich,
I am considering just what you've done with my 09 lmm -(90,000miles- occasional change filter p0087 limp on grades in 100deg heat) and have a few questions. I know you left your dpf in place(as I most likely will) and there were some regeneration issues - was that solved in tuning by John or where is that at?I have already added a fass 165 pump and replaced the filter head and lines there - otherwise stock well maintained truck. Now thinking JKs tune/ecm to keep me out of limp and get another 100k before injectors. Also edge cts2 for watching regens and other temps. Anything I'm missing?

Thanks Rich,
Paul

Hi Paul,

I probably was over fixated on watching the regens at first. The Edge was a novelty at the time, and I watched every parameter closely, trying to learn more about what the engine was doing. Regens have absolutely been a non factor in the long run.

And aside from that one code last year, on a ferociusly hot day on a long hill pulling a 12+k# fiver, the original problem has simply gone away. Just hit 140k miles this week, and very happy I did it. John's a hero!

I do have some building questions about whether it's time for a new one. But that's another post...

I think you got it covered. Good luck.

Rich

Thanks for that info Rich. When your truck coded that one time on the hottest tow did it limp or let you carry on? Thats my whole worry is being stuck on the side of the road with no shoulder and family on board. Also if the dpf is working I'm pretty well good to order.

Hi Paul,

It threw the code and I cleared it on the fly with the Edge, while towing up a big interstate hill. Never happened again.

I know my other move might have been to chop the afterburner, but I am not wired to go further away from stock. I think when the time comes to sell or trade up, being close to stock will help a bit on value for many prospective buyers -- if only to demonstrate I've not been hot rodding. Color me old school and conservative ..

Rich

Got the edge cts2 and Kennedy ecm installed. First start did have change fuel filter on dic and oil life was down to 11per cent. Since both were fresh I reset olm and ff life. No cel, no p0087 but stored codes for def sensors and maf which I've not had previous. Cleared those. Emailed John and he said those were normal for first start. Went for a spirited drive and all was well - truck seems smoother with more pep for sure. Won't be towing for a while but looking forward to it.

When we do an ECM swap the maintenance reminder percentages come over from the donor truck and need to be reset. DTC's should be automatically cleared after the ECM is flashed, but sometimes this is not the case. Drive it and see what it does. It may hit a point where it's unhappy about regen frequency to low, but it should work through that.

All makes perfect sense and was what I was figuring was happening. Not pulling to the Oregon Coast until the fall but may have to do a test run for fun before that. We live at the base of a major pass that climbs to 5700ft 6.5% grade for 20 miles. Should be a good test in the heat.

Thanks John
Paul
