I have a 2004 CAT C13 KCB21422 525hp and I am getting 5.4 mpg in my 42,000lb motorhome which to me is poor fuel mileage. I have a friend of mine that has the same engine although I don't know what year and he is getting near 7mpg and his motorhome weighs 6,000 lbs more than mine. I have an Allison 6spd trans and 4.30 gears in the rear. I usually drive around 64-66 mph. I was looking at the FLS and FTS numbers on my computer and they are FLS of 20 and FTS of -34. Can anyone tell me if those are the correct numbers for my engine and if not what do I need to do to change them. I understand these numbers can affect fuel mileage. I also understand that the 2003/2004 year engines have poor fuel mileage but that was fixed in the 2006/2007 ECM program. Can that program be installed in my ECM? I know I am a motorhome but I used to have a Freighliner with an M11 and a 10spd transmission.

I also have ECM #25546046JJ with personality module part # 2912048-00 dated MAR06 with module code 96. Does anyone know if this is the latest update for my engine?

'Your website is working well for me - This month I have shipped engines to Canada, South America and several in the USA. Thank You.'

Jim Williams, Diesel Power Train Co. Colbert, USA

'We sold a Turbo in 2 weeks to a guy in Houston! We also sold the first engine we listed - an old Hatz. It took 2 months to sell but that was OK as we couldn't move it locally. We track visitors to our website and we get lots from DieselEngineTrader.com. Your website really works, it's a great service and we'll be using DieselEngineTrader.com for years to come!'
