Tune it

Not much except perhaps timing, filters and nozzles.

The large component for labour is the time taken in the office to produce a creative invoice with the greatest number of zeros to get close to 1000.

Hi Wayne,

I think John is talking about a service.

When you get your diesel engine tuned it usually means getting your fuel pump adjusted for optimum performace and / or efficiency. This involves getting the vehicle dynoed and adjusting the fuel flow while monitoring exhaust gas temperature to make sure egt isn't too high to damage the engine but enabling you to get the most out of your engine.

I am talking about a non computer controlled diesel enginer here.

If its a modern CRDI ---- NOTHING...!!! Plug in the computer and check for any fault codes ( thats IF they do that )

When I put mine in for the 100,000k service and tune up,

Injectors checked and replace/cleaned.

pump timing checked to stock setting.

glow plugs and glow circuit checked for operation.

Basic tune up, about $200.00 plus what needs replacing.

Now if I out in in to be tuned on a dyno.

New filters - air and fuel, they will insist on them to get everything right.
New injectors.

EGT hooked up and pump timing played with on the dyno to get the best performance.
You need to say if you are looking for economy or power , or a compromise.

Usually costs $600 to $800 depending on what parts need replacing like injectors.

I do the filters myself before it goes in.
