The team at ITS autos have put together their years of engineering knowledge to hopefully answer some of your Frequently Asked Questions.


ITS autos uses genuine Toyota and Lexus parts. We use high quality oils grade specific to your vehicle. We are a VAT registered company. This combination allows us to provide our services to our customer’s vehicles while not affecting the vehicles warranty as per block exemption regulation 2003. This regulation states that a VAT registered auto repairer that uses genuine parts and specified grade oils has the right to conduct business without affecting the manufacturer’s warranty on the vehicle in question.

Which Engine Oil Is Best For My Vehicle?


Engine oil choice is Key To Good Maintenance!


ITS autos only use high quality engine oils we use the vehicles specified grade and viscosity to maintain your engine. Please inquire for more information about your vehicles correct engine grade and quality.


Quality Grade Oils Provide:


Protection – The oil lubricates the engines moving parts to reduce friction and wear, properties in the oil extract heat caused by friction of moving parts helping to maintain your engines optimum operating temperature and efficiency.


Efficiency & Performance – The correct grade of oil will maintain the highest engine compression with minimum resistance allowing for maximum performance with an efficient engine that leaves you more miles in the tank.


Reliability – Quality engine oils have a low ash content that reduces carbon build up within the engine and engine components, quality oils also contain corrosion neutralising properties that also help in reducing wear and complications.


Cheap or incorrect engine oil quality grades can cause:


Premature engine wear
Premature engine component wear
High levels of carbon build up
High engine oil consumption
Low engine efficiency and performance
Poor starting


Quality Oils are graded by Society of Automotive Engineers (SAE)


Toyota and Lexus vehicles can use the following API grade oils.


SL Energy-Conserving
SM Energy-Conserving
SN Resource-Conserving




(International Lubricant Standardization and Approval Committee) Certification Mark is added to quality oil containers to help you select the oil you should use.


Toyota and Lexus passenger vehicles all use either SAE  0W-20 (SL or SM) or SAE 5W-30. These oils are used to allow for the best fuel economy and ensure good starting in cold conditions.


The oil grading can be translated in two sections. The first section is 0W or 5W this relates to the oils viscosity rating, the lower value of the first digit before the W relates to a thinner oil allowing easier starting of the engine in cold conditions.


The Second section of the oil grading is either 20 or 30, this relates to the oils viscosity at running temperature. A higher value would be used for an engine operating at higher speeds or loads or a hotter running diesel fuelled engine.

What parameters do we adjust?


We adjust various parameters within the map such as fuel pressure, boost pressure (turbocharged engines) ignition advance and throttle pedal control, amongst others to release the true performance from the engine.


What is OBD Remapping?


OBD remapping is simply engine tuning, or engine remapping carried out via the use of the vehicles on board diagnostic port (OBD2).


What is an ECU Engine Control Unit?


The ECU or Engine Control Unit could be described as the vehicles ‘brain’ it contains a processor and software ‘map’ that takes information from the vehicles sensors and passes its decision to command actuators to control the engine as per the requests and demands of the driver.


Why does a manufacturer set their software ‘map’ to a standard default setting?


Default software has to take into account the operating conditions for the region of the vehicle, including varying climates, temperatures and altitudes, emission laws as well as various quality of fuel standards.


Buying / Selling / Resetting to Original 


If you are buying a vehicle with remapped software or are selling a remapped vehicle and want it set back to original factory standard then we can provide this service for you. Software or Hardware modifications to any vehicle usually add value as well as performance.


Will remapping invalidate my vehicle’s warranty?


Remapping vehicle software is not something that can often be detected by main dealer diagnostic capabilities. The upgrades we provide will not cause any failure to your vehicles components, as we do not over tune. If a main dealer overwrites you’re map and sets it back to original standard due to any warranty work or a warranty recall then we will happily re-install your remapped software for free for as long as you are the owner of the vehicle.


Should I inform my insurance company?


We advise that as insurance often states you must notify of any modifications then you should notify them that you have had your vehicles engine software modified. Most insurance companies will not raise their premium especially if it is a remap for economy.


Alternative Tuning modifications


There are a lot of cheap and nasty tuning options available on the internet from cheap downloads to power increase modules that you can plug into your OBD with over quoted gains in performance. The old saying you get what you pay for is the key here! The plug in modifications often just trick your vehicle into thinking it is running cold to fire in extra fuel or bump up the fuel pressure signal. This is not an economical way of increasing performance as all the other parameters are not tuned. With a full custom remap a large quantity of parameters are adjusted and tuned together to alter hundreds of signals and data files from the ECU to the engines actuators and sensors.
