Yeah good write up, BUT rotating the BC pin on its axis also effects other fuelling. Might pay to mention that as well.

Depending on the brand of compensator as to what eccentric cam they may have , Adjusting
this can cause problems some times as its all dependant on position of tension / gov lever ,
length of through pin ( pin that contacts boost pin /cam and boost toggle internal of pump) causing some of the effective range of the compensator not to work and one pump may vary to the next , also the max fuel/ full boost shim needs to be adjusted keeping in mind that boost pin/cam cant bottom out on through pin as this can reduce fueling aswell also depending on brand (Bosch Zexel Denso ) and even depending on different pump numbers , there are a whole lot of different boost cam/pin profiles .

The electronic Hartridge test bench makes quick work of this!

Swaffie

Another basic feature of rotating the aneroid pin is it will change the no boost fuel setting which needs to be taken into account during the whole tuning process !!!

in which way does rotating the diaphragm effect the no boost fuel. ie more or less fuel if turning to a more steep ramp setting on pin.
just trying to work it out as my td42t pump is a bit lazy down low but once going if fine. would this be it?

The biggest part of the step gives more no boost!

Im trying to keep it to the bare essentials to give people an understanding of how it all works.
There is many factors that effect other things when tuning the compensator as you have said Matt and Swaff.

If you guys want to try and do a write up on these things, that explains indepth how things effect each other please do, and I can quote your write up in my original post and maybe put it under an advanced section or something of the likes?

Thanks fellers for helping me understand diesel tuning a bit better, I've only just got a td42t GU and I'm trying to get to grips on the way the engine runs, it does have boost/pyro gauges fitted and things are starting to make sense. Anyway thanks again for your explanations and I hope to see lots more.

Very good write up and really enforces why you should get a diesel tuner to tune your engine as there is so much to think about.

Mods, sticky??

Hi DieselTuner I have a list of mods done to my TD42 one being a 12mm pump. I have been experimenting with some modified fuel delivery pins.



I am currently running the fuel pin on the far right in the pic. In the boost compensator their is a 10mm shim. I am wanting to try without shim to see if their is a difference. What do you think ? Also will this be okay to run no shim.

Two things will happen. You will make more fuel and power under full boost, but the pin running on the ramp may then touch the horizontal cut out. With a lot of boost and time it may damage the pin.

May I ask whose fuel pins are they.
