→ Plug and Play Re-maps and Files Sold on E-bay, any Good?
There are a number of basic power upgrades available in a plug and play format or are downloadable from the web. Whilst some of these items can offer slight increases in power, they operate by merely adjusting a specified signal within the ECU by a set tolerance. It's impossible to compare these inferior upgrades with a full rolling road re-map which measures and adjusts hundreds of signals and data files within the ECU.
We advise that these generic files and unsupported devices for sale on the web should be avoided at all cost. We've seen too many customers come to us after a bad experience - and there was no one else to turn to either. We're always happy to advise on your tuning needs.
→ Service Exchange Units?
Service exchange units, either new or repaired are units that we send to you and then once fitted you return your old units back to us. If you do not return your old units or they are returned damaged then the surcharge price as indicated on your original invoice and return note will be charged to you.
Service exchange units will be supplied with a 'core return note' an addressed pre-paid return label. (U.K. mainland only) Your old units need to be returned to us, in a repairable condition, within 30 days.
To return 'old units', simply place in the box used to supply the new units with the 'core return note', stick the pre-paid addressed label on the outside and take to a post office. Please obtain a 'proof of postage' receipt when returning old injectors, as the onus will be on you to prove that the old units had been posted should they be lost.
→ Should I tell my Insurance Company?
Whilst the upgrade in many cases is undetectable, the responsible and correct answer to this question has to be "yes", your insurance company should be notified of any modifications including tuning. However, the good news is many insurance companies do not penalise you for upgrades of this nature, particularly if you're tuning for increased fuel economy.
Adrian Flux is one such company.
→ VE two stage injectors, how do you set them up?
The set-up of a two stage injector is very important to get optimum performance from your vehicle. If it is not set up correctly it can restrict the mount of fuel delivered on the other hand it can dump too much fuel in causing black smoke.
The nozzle choice is also important but we will cover nozzle sizes in a differant FAQ.
The set up is all to do with NOP1 and NOP2 (nozzle opening pressure) NOP1 is easy enough to do as this can be done on a standard pop tester.
Nozzle Opening Pressure (NOP2) cannot be detected by measuring only pressure or only flow. Similarly injected delivery alone does not give an indication of NOP2.

→ What Condition do Old Units Returned On Exchange Need to be in?
If units have been supplied, as service exchange units your original units will need to be returned to us, using our prepaid addressed label, in a repairable condition. This means that:
- There must be no damage caused by overheating, being chiseled, smashed, bent, distorted, heavily corroded or have parts missing.
- The old units should not have had acid, water or other aggressive chemicals in them.
Should a unit be damaged, as above, the surcharge price as indicated on your original invoice and return note will be charged to you.
→ What is a PD injector upgrade and how is the injector calibrated?
Unit injectors incorporate the nozzle assembly and a built in high pressure pump producing injection pressure of up to 2000 Bar. Similar to that of a common rail system but with the fuel rail chamber only needing a supply pressure of 2.0 Bar.
→ What is a VE injector power upgrade and how is the flow checked?
Using the 2 Stagemaster's flow mapping ability we are able to map the flow characteristics of each nozzle prior to fitting in the injector. This test is performed on the nozzles prior to installation to insure that every nozzle performs exactly to specification. We are able to evaluate delivery rate, peak delivery volume as well as flow through the flow range.
→ What is an Injector Leak Back Test?
Pressure loss within a common rail fuel system can often result in one or more of the following symptoms:
- Hard or difficult starting
- Erratic or uneven tick over or idle
- Lumpy running
- Hesitation on acceleration
- Smoke on tick over or acceleration
- Lack of power or even a total shut down of the system
One of the main reasons for pressure loss is due to excessive fuel being returned to the fuel tank, also known as back leakage.
Once the injectors suffer from excessive back leakage, the fuel pump cannot generate enough pressure to enable the system to operate. This is more pronounced at starting or tick over due to the fact that the pressure generated by the pump is directly related to the engine's revolutions which are lower at start and tick over.
In a colder climate the engine rotates slightly slower thus lower pump pressure whilst with warmer fuel the viscosity is thinner thus allowing worn parts to leak more.
→ What is involved in tuning a Nissan Navara?
The last 15 years have seen pickups go from workhorse to lifestyle vehicle, but the Navara has never strayed too far from its practical roots and gets pretty good reviews from the critics.
Having had a lot of experience Tuning Nissans I will be honest with our findings.
We have found that the best tune is our Performance Tune, this improves the drivability of the vehicle to no end, better acceleration, smoother drive, a lot
less gear changes when towing or going up hills. It does not improve the MPG if the vehicle is loaded or towing but there is about a 5% fuel saving when not loaded.
We fine tune to ensure that the map is bespoke, as we do not supply generic maps and guarantee that every tune is customised to suit your driving style and needs.
The gains that are achievable are,
Power Tune = 35 Bhp and 70 Nm Torque increase
With a fuel saving of 5% achievable.
Fuel savings can only be achieved with a “like for like” driving style
All tuning is insured and comes with our 30 day money back guarantee. I would also like to put your mind at rest with regards to the ECU being over written at a service or back at the main dealer, as long as you own the vehicle will re map your vehicle to your chosen tune at no extra charge.
With a JTAG tune
The Navara is challlanging to remap as it is needs "open heart surgery" to get it right. Many owners have tried a tuning box but have experianced it to be unreliable. We have had the experiance to do a remap via the open ECU with great results.
