Troubleshooting
-
None of our tuning boxes touch your vehicle's ECU software or other electronics and do not make permanent changes which would be detectable. However they can be quickly and easily removed altogether if you choose at any time reverting your vehicle to factory standard.
-
We do not recommend it as your vehicle already has been fine tuned for more power. However it's worth noting that a tuning box will yield the same power gains but gives you the flexibility to remove the tuning box at any time being fully un-detectable.
-
All our tuning boxes are completely safe and will not damage an engine in any way. We have been tuning diesel vehicles for many years and have extensive knowledge on what settings each tuning box needs for the specific vehicle it's being installed on. All of your vehicle's existing safety features are always in full control of your engine. None of our tuning boxes override or alter your vehicle's settings at any time.
-
No they will not.
-
No you do not have to at all. Most of our customer's leave these tuning boxes installed at all times and have never ever experienced a reason not to.
-
This is down to your dealer, the manufacturer, or whoever sold or maintains a warranty on your vehicle. However, all our tuning boxes are designed to plug in and be removed very quickly and easily. This ensures that if you wish to remove the tuning box for maintenance or servicing you can do but this isn't a requirement.
-
Yes we can. If this is of interest to you please give us a call or send us an email and we'll be able to advise a price and availability.
-
No you shouldn't have to as our tuning boxes are designed to plug straight into your engine with the connectors provided. The only exception is our Landrover TD5 tuning boxes which do.
-
If you can't find your vehicle using our quick search feature at the top of this page please do not hesitate to send us an email query or call us and we'll do our best to advise you if a tuning box is available. We're always adding new vehicles so it's best to check if in doubt.
-
As our products count as a modification to your vehicle and affect the power rating we would advise you to contact your insurer and inform them of the installation.
-
Our products are designed to override no safety features of the engine they are programmed for and their use will not result in any damage to it. Engines faults can occur naturally as part of everyday wear and tear and are a typical event during ownership of any vehicle, as such we do not offer any additional warranty beyond our standard product warranty.
-
First, try completing disconnecting the tuning box and attempting a re-installation, this will help you ensure you have installed it correctly with all plugs firmly attached. If connected the wrong way, the tuning box will not receive power and the LED will not illuminate, thus preventing the engine from starting or operating correctly. Check your connector installation and see if the LED now illuminates allowing the vehicle to start.
-
If you install the CRTD4 Tuning box into your vehicle and the engine does not start, you may be experiencing a poor connection. Please recheck all connections to engine and check that the surface mounted LED on the tuning box illuminates when the ignition is on. We would recommend you try re-affixing your connectors.
-
Have you changed the unit operating mode to maximum setting? Did you drive the vehicle for 10 miles between increasing to each of the modes? If not then you may need to step back down to the starting mode, 4, and follow our instructions for adjusting your Tuning Box. If you followed the adjustment instructions and still have a warning light at the maximum setting, adjust the box back to setting 4 and contact our customer services for further guidance.
-
You may have not installed the product correctly, we would suggest first attempting a re-installation of the product in order to ensure it has been correctly installed. Following this, we would suggest increasing the box mode to its maximum, please refer to your supplied instructions on how to do this. If you have done this and feel you still see no improvements please contact us for further guidance.
-
If you start your vehicle after attaching the Tuning box and experiencing excessive smoking, this could be a simple case of personalising and adjusting the unit to suit your exact fuelling characteristics. Adjust the settings on the box to the left one position, then road test the vehicle. Excessive exhaust smoke could also be caused by a split in an intercooler hose so a visual check of these components is highly recommended.
-
First, disconnect and re-install the product which will ensure no connections have come loose or any damage has occurred to the box or connection harness. When re-installing the product, set the tuning box to its standard setting of level 4. If the problem re-occurs contact our technical department for further guidance. If re-installed and no problems occur at level 4, move the tuning box up to its maximum by one setting every ten miles at a time.
-
Users of our products can become accustomed to additional power and torque over several months or years of ownership. First we would suggest to check the LED on the tuning box receives power. Press it to adjust up or down one to test. This information will be important later should you need to contact us. Second we would suggest to uninstall the product and see if you notice a degradation in vehicle performance. If with the box removed you feel performance is unchanged then please contact our customer services department, it may be that your unit has developed a fault.
