we need a skoolie meetup where i can bring my device and everyone with the T444E or DT-466E could reprogram their computers...

my Bus goes into the paint shop here soon, at that point i wont need the device for awhile.. Need to find a way to safely ship it around.. it seems pretty durable..

At $700 there must be a cheaper alternative...

I got my injectors here https://dieselpartscanada.ca/ I'm in Canada, at the time they where $275. each these are brand new not rebuilds, you can take yours and have them tested, and rebuild maybe cheaper. I didn't use a different injector for number 8 cly mine where all the same so I left them that way and there stock size. keep in mind I replaced mine cause they needed to be. it was a improvement, and increased mpg by 1mile

just looked at my thread and the injectors $244.00

were you getting errors? how many hours / Miles (or KMs) on your engine?

the #8 injector difference was a TSB, so if it had never been performed then you wouldve had all 8 AD style injectors...

later versions had the higher pressure fuel regulator too so you may not have even had or have the low idle knock.. I'll know tomorrow when I replace my regulator with the updated part..

if I go to the trouble of yanking my injectors, i know myself I'll replace them.. esp since ive got 8000 hours and 144k miles..

NC for instance is 6:83 on the standard bus and 6:50 on the activity buses at 215 HP, to get little Johnny to his game faster.
BuddyvZ, where in the NC is low gap?
I have an NC bus with 6.50 gears, it is far from an activity bus speed wise and I was told by the bus barn men that if I didn't change the gear ratio when I got rid of the governor's Then I would burn up the rear end and that was buying the bus set to do 49-mph?
The op's gear size and your post contradict a lot of what I have been told/read/heard? Maybe it's my specific rear end?

I never heard anyone say a rear end would burn up... I would say though that spinning the driveshaft extra fast could eat the bearing in the pinion if its not properly balanced.. but a properly balance driveshaft and the right pinion angles seems you should be able to spin it very fast if you want..

I am about forty miles north of Winston. I got that information from the service manager at the High Point White/International dealer. The High Point site is the site that handles the bus sales and I was directed there by my local White service center, more for actual configuration setups (motor,trans, rear end) from someone on the sales team. They have been incredibly helpful and very forthcoming with information.

changing the #8 injector was to try and make the motor quieter , I think it was a AE injector, it was really for the ford excursions and super duty trucks, people would complain about the "crackle noise" and really didn't matter to a school bus, but can be done.
I had about 210000kms on mine, I had no codes, my bus was puffing blueish smoke, and was gutless till it reached operating temp, once it warmed up it ran ok, the o rings where worn, and the injector tips where worn

yes, correct, the #8 caused no harm..(the TSB even states that).. it just sounds like a rod knock... I dont have any smoke on mine that I can see and still have good power (esp in a short bus) through all temperature ranges.. though I do believe my thermostat is bad so im replacing that.. I get way too much coolant flow through the radiator early and then seem to lack a bit (doing a rad in and out temp test) when the bus gets really warm. indicates perhaps i have a T-stat stuck in a partially open position. the bleeder hole in these tstats is not big enough to be pushing as much coolant through as im getting.

the fuel pressure regulator update claims to fix alot of the "injector knock" complaints.. plus it was made standard later.. i figured a sigmificant change like system fuel pressure from 47 to 72 and made factory default in later versions was done for a purpose... it was done in AD injector engines and is recommended on mine..

the "knock" just annoys me is all.. im wierd that way... came from building chevy hotrods with hydraulic valve-trains super quiet.. so naturally diesels to me are a different breed...
