ISX 450 Intermittent Mystery Derate

[Rawze]

The old N14's were called the 'CELECT' and 'CELECT PLUS' in CT back in the day. The 3-letter code was usually 'ECI' for most of them.

My best advice.. if you have an N14 that is still running.. donate it to a museum or turn it into an RV, and stop trying to run it down the roads with freight at this point. - You can't get good injectors for them any more, or a lot of other parts that are good oem quality .. and their fuel mileage is not that good. - its kinda a wasted effort for the most part vs. anythng with a VG turbo these days.

just my own thoughts on it any ways.
