I have a 2005 Holiday Rambler RV with Cummins ISC 330hp. It appears to have HPCR not Caps injection pump. They call it caps ll I believe ? This tuner is listed only for 06/07 though and the one for through 05 lists for Caps only. Is there one that I can use for my year and ESN? Also I noticed the lift pump replacement says it is only for the Caps system, is that not recommended or needed for the hpcr. thanks ( Arnold Hastings, 05/20/2020 )
Yes you are correct, your engine does use the common rail fuel system "CAPS II" fuel injection pump. We do not see near the issues with these so a FASS pump is not critical. If you want to install a performance module, this is the one we recommend for that engine/fuel system: https://www.ultrarvproducts.com/12000-AG-Diesel-RV-Power-Module-ISB-ISC-ISL-Common-Rail?search=12000
