How to DE-Tune a diesel.....I know it's crazy but....

[AndrewKing]

Hi All, Don't get me wrong and I know it sounds crazy but I'd really like to know how to LESSEN the power output of a diesel engine WITHOUT hurting economy..... The reason I am thinking about doing this ( BTW I love power in MY truck) is because I run a lawn care company and this summer I will buy another diesel truck for the crew to use (I have been using WVO so fuel costs will be near zero this season)... . I want to detune their truck so I won't have to worry about trannies and overall hot rodding on their part (yes I try to hire responsible people but you know how that goes... . )... . I have thought of doing what I did on my gas truck (installing a spacer under the accel pedal to limit throttle travel but since diesels make so much power down low I didn't think this would be a good approach..... I will also install a turbo timer to keep the turbo and guard against hot shut downs..... only thing I have to figure out... . or if you have any ideas it would be appreciated... . is how to make the unit (timer) automatically operate when the key is shut off instead of having to press a button (I have the howard timer in my truck)... is there a way of doing this with brand timer or is there another unit that will work better? Thanks in advance for all your help,

Andrew

detune

I understand your intent but I think detune is the wrong word. You want full economy of function but less power and speed. Lengthen the throttle cable so that it won't apply full throttle. There is a high fuel stop that can be set for less fuel which will reduce the output as well.



It wouldn't seem to me that you would have to encourage any help to take an extra couple of minutes to goof off as the engine cools.



What is wvo?

I'm not 100% sure, but I think "WVO" is waste vegtable oil.

Rotate the fuel pin to min travel. That will limit the power.

Allow Jay to wrench on your truck and It'll be de-tuned fo' sure :-laf

Goes as tight as you can on the diaphram spring by turning the star wheel all way counter clocked till it get to the top of it's threads ... ... . but still has enough thread to stay put.....

Yep starwheel as csnider said, fuel pin as J said, and as James stated, that 'high idle' screw, turn it as far in as you can so they won't get big time throttle travel- that is or will be only able to turn say 2500rpm not ++++.

Just buy a chivy with a 6. 2/700r4 and 3. 08's. That will keep em from hot rodding! :-laf



Sorry I couldn't bring any useful info to the table, but I could not resist.
