We left Hillsboro on Monday morning and worked our way over to I-205 in order to miss the Portland morning traffic. We continued north and stopped at our friends business, TrailTech in Battleground WA. After a short visit to confirm summer riding plans, we headed to Centralia WA to confront the company that had installed the ‘Performance’ chip in the motorhome.
Now that it is all over, I have to give these guys a huge
amount of credit, for not losing their tempers with us. We walked in, madder than mad about the
blow-up of our motor, which we credited to their chip. Jon Brazel was very calm, and listened to our
rant before agreeing to get our money back on the chip which was no longer in
our motor (having re-mapped the brain himself earlier in the process). He then
suggested they put our coach on their Dyno machine, to see what was really
going on. Remember in Quartzsite, they
claimed to have tested the motor and all was good, that was why they continued
on and put in the chip. They invited
Wayne in to see the computer as they ran it through its paces. Sure enough at
idle, all the numbers were in the normal range, but when they put it under
load, the problem showed up. First they
changed the Mass Air Flow sensor and some of the numbers came back in
line. Then they changed the fuel
regulator, explaining that they thought it was the fuel pump (they had been
saying this all along) but this was a good first check. They were surprised when the regulator turned
out to be the problem. We’d had the fuel pump tested in Wickenburg and were
sure it wasn’t the issue, so we weren’t surprised.
Jon charged us his cost for the parts and did not charge for
labor, and got us our money on the chip back.
We had gone into his shop mad as can be, and left as happy
customers. We still had to suck up the
cost of the new motor, but now the issues are taken care of, and we feel
better about selling this coach, no more check engine codes!
