diy diesel tuning
This increases the amount of fuel delivered depending on the boost pressure pushing down on it. This guide will cover the basic Tuning of a Diesel VE style rotary pump found on both Nissan Patrol TD42, Toyota Landcruiser 1HDT. 5) Compensator Pin Rotation (for eccentric pins only) (overall on boost fueling). If the pump is rotated one way, this pressure will build up earlier in the stroke, meaning Crack pressure will be achieved earlier than normal resulting in fast or ‘advanced timing’, If we rotate the pump the other way, the crack pressure will build up later in the stoke, resulting in the injector firing later or ‘more retarded’. If you own a diesel and do the same thing, you may end up with an engine that’s prematurely dead. With an equal and progressive amount more/less throughout its rotation. Just Autos have the master tuning hardware and software required to complete custom remaps of the factory ECU in your Nissan, Toyota, ISUZU, Holden, Ford, Mitsubishi turbo diesel vehicle. With the advent of high compression engines, turbo chargers and direct fuel injection at phenomenal pressures we have a range of diesel engines that out perform thier petrol counterparts and return better fuel economy. Due to limitations in editing, I have decided to move it to the website to allow additions and modifications to it in the future. We can reduce or increase this tension by adjusting the size of the shim that is underneath the spring. We detect all unauthorised copyright material taken from our site the moment it is picked up by the search engines using pattern matching tools. Thicker shims mean more tension, thinner shims mean less tension. With turbocharged engines we have vastly different amounts of airflow on boost to what we have off boost. Do not move the timing on these pumps from the preset or factory point as it will effect how the computer controls the pumps timing in a negative way. Injectors have what is called a ‘Crack Pressure’ How to Check Automatic Transmission Fluid, How to Tell Whether Your Vehicle Needs a Tune-up. Body Kits How do they work and are they worth buying? Similarly, anything that isn’t using electronically managed direct injection is a pointless tuning proposal so we are somewhat limited to modern Turbo Diesels.
styling and friendly car banter. Diesel Tuning for maximum power and torque. It does this through a pressure intake port in the top of it, which pushes an internal diaphragm containing the fuel pin down into the pump. We have a policy of actively enforcing our copyright*. If you own a diesel and do the same thing, you may end up with an engine that’s prematurely dead. Track day insurance Injection timing & how it affects power, torque and economy, Brands Explained – who does what and how they do it. So it is very important to remember, there is more than one timing adjustment on this style of engine. Of course there is many other pumps out there that this guide will be suitable for. MPG calc This means that your ECU does not need to be removed or tampered with.
2) Compensator No Boost Screw (off boost fueling) This is the pressure that the fuel forces the needle/pintle off its seat, and allows fuel to flow through the tip of the injector. Most service facilities are pretty nice about that kind of thing. But do the claims live up to reality? Do not adjust the maximum speed governor unless you really know what you are doing and why. It is important to have these checked/reset every 90-100K kms due to the spring loosing tension over a period of time.

The same goes for changing filters: A dirty fuel filter can impair a conventional vehicle’s performance, but dirty fuel can clog a diesel’s fuel injection system, and you may need expensive professional help to get back on the road again. And please remember, this is a Basic Tuning guide only. Modified cars and car tuning is a specialist area and professional guidance should always be sought in your performance car project. If you own a conventional gas-powered vehicle and you get sloppy about maintenance and don’t change the oil often enough, you’ll probably end up with an engine that has aged prematurely.

Regular maintenance is absolutely imperative if you want a diesel engine to last, and every diesel owner will probably encounter some pitfalls and problems.
A ‘Compensator’ is designed to modify the pump in a 3D fashion dependent on this extra flow/pressure the turbo provides.

We look at all aspects of diesel engine tuning and suggest that you join our forum for more information about the world of high performance diesels. Standard Non Compensated Pump Fueling on a naturally aspirated diesel. As the pump ramps the pressure up to Crack pressure, the injector will fire.
In the case of a tired or worn out pump, it is normal This is the only adjustment on a non compensated pump. Our content is protected by CopyScape. This gives us an overall adjustment from 0psi to full psi. If we lower the pressure they open at we effectively advance the timing of the injector firing sequence, if we increase it we effectively retard the timing of the injector firing sequence. If you’re not sure, ask one of the service advisors at your dealership to show you where the oil, air, and fuel filters are located and what’s involved in changing or servicing them.
You can have thicker shims in the injector to increase injection pressure which is good! Its for this reason alone, the fuel screw should be kept as is until more overall fueling is required. This is an important consideration when getting the injectors re-conditioned, especially if higher pressures are recommended by the shop performing the work for you. From a diesel perspective, anything that isn’t turbocharged is a waste of time from a tuning point of view. Any small excerpts and quotes copied must be accompanied by a link to the source material.

The main drawbacks to using just the fuel screw on a turbo engine is it doesn’t take into account the extra pressure or flow of turbo adjustments or upgrades. In most cases the fuel pin is eccentric. We look at the various stages of remap available and the mods that would work best on stage 1, 2 and 3 upgrades.
