The blue chip "upgraded VP44" from all my reading on his site, and from my experience today, is simply a totally re-manned/new VP44 from Bosch. Bosch now uses the steel bushing in the timing piston, as well as the steel bushing by the diaphram. How do I know? I spent the afternoon at a Bosch certified service facility getting another one. The man that does it walked me through his shop showing me the equipment and testing stations. At that facility, everything is done, and he told me that Bosch now mandates that a re-man gets all the parts and work they do over there.
***The FedEX situation with the computers was also explained to me, after he quit laughing. It was UPS in fact, not FedEX that requested the change. The change made was not because of failures, ALL new Bosch computers have the update. UPS requested that the computer log how many times the VP44 starts and stops, and they made that number avaliable to the techs in the UPS service centers, so that when the pump has been started/stopped/ran so many times/so long they could track it and replace it at a pre-specified number, to prevent the chance of failures on trucks in the field with a worn out pump. I don't know what drivetrain either FedEX or UPS use. Might vary.
The new computers are delivered to EVERY certified service facility that remanufactures them. They are actually blank, and the facility actually "burns" the necessary programming into the pump for its specific application. They do this because the system is used on not only trucks, but also things like marine applications and generators, pumps, etc. Logistically Bosch sends "blank" computers to the service shops to program them to whatever the customers application is.
It was really really cool to get the tour from the owner of the company and see how it really works, the test unit and rebuild benches are incredible! Super nice guy, and I walked out with a totally new VP44 because mine went POOF the other day.
I am in no way saying anything about ANY of the vendors on this site, I'm just clarifying what is going on with the new VP44s, according to the buisness owner.
From what he has told me is that anybody who orders a pump needs to make sure that it does have a new computer, if not, it did not go through a certified Bosch re-man shop, and might not have all the needed mechanical updates. Just be sure to ask, all the guys I talked to about my truck on here are great, I just chose these guys because I could pick the pump up myself and talk to the man in person.
