Just another confirmation of outstanding service by Cummins NW.
We were having the Source Engineering Wax Valve installed just down the street from them in the AM. With an appointment later in the day to have Cummins NW reprogram our ECM from ISL370 to ISL400 configuration.
I called in the AM to see if they had a thermostat in stock for our coach. (Figured with the thermostat exposed for the Wax Valve install, a good time to replace it.) Parts gent looked, said know, but - were supposed to have a few coming in with the parts deliver that day. Which was supposed to be between 10:00-11:00AM timeframe. I walked down to their shop to get the part around 10:30AM, and the delivery truck was pulling out. Went in and asked for the gent who I had talked to (Name escapes me now.), and he said give me a minute to see if they were in the delivery. Three mins later, he walked out with the thermostat. Said we had to wait a few mins for another gent to enter it into their inventory stock, and that he had just gave him the paper for the three thermostats they'd received that day. Total time for me at the parts counter was 15 mins. Pretty cool people!
Later that afternoon, Source Engineering Wax Valve and their Air Line Check Valves too, were installed. Drove down to Cummins NW, and 20 mins later the tech was their plugging in the computer to the rear port. He scratched his head a few mins, asked me to come look at his screen. My ECM was identified as being in either Brazil or Argentina (One of those two.), and he asked if I knew why. I told them that we'd had help trying to have a customer reprogram of the ECM, by a company out of Canada, who also had a programmer in Germany in the mix. Every back and forth attempt of reprogramming (Done in Washington State, with file transfers back and forth.) - would take 48 hours. They had not done a CAPS era ISL before, and were having problems. Due to time schedule, we ask the shop to go ahead and restore our 'as was saved ECM profile' which was from an ISL400 reprogram done in California two years earlier. That failed for some reason. And they had to call a mobile gent in with the write Cummins software to help. All he could do was get me back to ISL370, and even then he was not positive of all of the settings. (I had a print out of the config from the ISL400 out of the Cummins Cal Pacific shop, and he copped as much of that as possible. But, we were at ISL370 level again. He too noted the South American identification on the ECM. And we all concluded it was from the failed attempts to custom program the ECM.
So the tech at Cummins NW said well let's see what we can find for you with this Country Identification on it. He scrolled thru many configs, and finally said he had two to choose from. And we brought up the HP/Torque curves for both. They both had 400HP, so I chose the one with the flattest curve for Torque, the HP curves were pretty close, with the one I chose needing a bit more RPM's to reach max HP. (He said they were identified as OTR's engines.
I felt that the Tech went out of his way to help me make a good decision. And by the way, we compared that config with the California 400 config that Cummins Cap Pacific had used (Their only option in California.) - and I like the one a have now better. Of course that is looking on a computer screen, and as many have noted before, very minor difference between the ISL370 vs 400 in real world driving. A big more HP for hills, but the 370 Torque Curves were just about the same as the 400 in California config.
So a firm endorsement of Cummins NW:)!
Best to all, travel safe, have fun,
