What does each Unichip map do?

#1: Anti - Theft Immobilizer Map. 

  • (Premium/ Deluxe) The Anti - Theft Immobilizer Map is an intuitive means of deterring thieves from stealing your vehicle. When active, your ignition will turn over, but there will be no throttle response when the pedal is pressed. The sound of your engine idling outside of your house will spook potential thieves. No thief is staying inside a running car they can't move. Best used in conjunction with the Bluetooth or Key Fob Edition map switching devices.

#2: Stock / Standard Map. 

  • (Premium / Deluxe) Every Premium or Deluxe tuning box / device that Unichip create is able to access your existing ECU's original tuning file. This is a great resource for any engine diagnostics you may need to run - there's no need to unplug your Land Cruiser Tuning Kit to do this! This is especially useful for the 100 Series, as your kit will be installed behind your vehicle's glovebox.
  • It's also a fantastic means of comparison for the extra power increase, not only to remind yourself of the "night and day" difference - but off your newly found power to unsuspecting passengers.

#3: Economy Map. 

  • (Premium / Deluxe) Unichip Europe's Economy Maps are completely unique to rudimentary tuning devices. Why? They recognise and eliminate any of your sudden throttle pedal movements, ensuring acceleration response is as smooth as possible. In most cases, the only thing stopping you from being an economical driver is the person behind the wheel.
  • Following this, the Unichip Economy Map will give you more power, lower down in the rev range. This, in turn, allows you to reach cruising speed more efficiently.
  • An added failsafe - if the Economy map is active and you put your foot right down on the accelerator, the Unichip recognises this as you potentially being in danger (you might need to move to avoid traffic etc.) - the Economy Map's configuration changes and will give you more power. 

#4: Off - Road / Towing Map. 

  • (Premium / Deluxe) More often than not, customer's purchasing our Land Cruiser ECU Tuning Boxes require extra power to aid towing large trailers / horse boxes etc. There's also a cult following of individuals using their Cruisers for greenlaning & general off-road use.
  • This map, once active, grants the user significantly more power, lower in the rev range. This makes setting off with a large load easier, makes sharp inclines more manageable, and off-road pursuits significantly easier to overcome.

#5: Performance Map. 

  • (Standard / Premium / Deluxe) All of the power, across the entire rev range. Refer to our dyno graph to visualise power output. This map is typically the reason why the majority of road users buy a tuning device. We're able to extract a significant amount of power from your 1HD-FTE engine - but fear not; this is at no risk of your gearbox or mechanical components.

Customer Reviews:

"I am based in Kenya, Africa. ordered a Plug & Play Unichip for my 100 series Landcruiser 1HD-FTE. Ordering process was brilliant - the guys at Unichip Europe made it so easy for me. I had a few questions which I got answers to straight away. I fitted it myself - took half an hour. I had a question on the day of fitting - and emailed them and I was shocked to receive a reply in less than 5 mins - that's what you call customer service! As for the product, I seriously dont have enough words for it. Just gobsmacked. It has unleashed some serious power on the 1HD-FTE especially at low revs. Car pulls like a train and just keeps going going going. I wish I had done this sooner!"  - P. Shah | Land Cruiser Amazon Unichip Tuning Kit Owner.

Important Notes (Read):

  • You'll need to purchase a map switch in order to switch between your pre - programmed maps. Browse our range here, or refer to the guide above for more information.
  • If your vehicle has a conventional actuator-controlled wastegate turbo instead of a VNT turbo, we'd recommend the use of a boost control kit. Identify your turbo type here.

Frequently Asked Questions:

  Can I install a Unichip plug & play kit with limited / no technical know-how?

Yes. Our kits are designed to be hassle free & simple to install. Locate your ECU, unplug it's existing wiring harness, plug in the Unichip - job done! If you're unsure about the process, our workshop is open Monday - Friday | 9AM - 5PM GMT. Give us a call!

  Will I need to purchase a Map Switch, too?

If you're purchasing a "Premium" or "Ultimate" Kit, then yes, you'll need to purchase a Map Switch in order to access our pre-programmed maps. If you're purchasing a "Standard" Kit, you will not need a map switch, as they're programmed to hold just one tuning file. Refer to the product listing's title if you're unsure. NOTE: Unichip Europe Kits with a drop-down menu below the "Buy Now" button will NOT need to purchase an additional map switch. The Premium editions now include a map switch incorporated into the price for these particular items.

  Why should I pay a premium for a Unichip Plug and Play kit?

If you're serious about tuning your vehicle and have shopped about, you'll have definitely noticed the wild west that is the chip tuning industry. The Unichip Module is a multi-processor ECU tuning tool, it is not a chip tuning product. The sheer amount of engine parameters we're able to manipulate means that every single file is meticulously tuned in our in-house rolling road. Unlike some our competitors, our map files are not just increments of the same map, giving you slightly more power every time. Every map is detailed and lives up to each of their individual namesakes. This can take days, or even weeks to perfect these tunes. Couple that with industry-leading product materials used across the range, an anti - theft immobilizer map as standard to all premium / ultimate products and a spectacular after-sales service, and the Unichip Products truly live up to their value. More information can be found on our "self fit" page, located on the menu bar.

  How are your tuning kits different from chip tuning boxes or remaps?

Chip tuning boxes share only a few similarities with the Unichip Module. They'll typically alter just injection timing or injection pressure. The Unichip gives a reputable tuner a myriad of different parameters to manipulate, creating a far superior tune, a much better spirited drive, all while ensure there's 0 risk to your engine's mechanical components. A remap will physically alter / overwrite your existing ECU file. Done correctly, and you'll have access to one map with more power. Done incorrectly, and you risk damaging your engine's mechanical components. These changes are semi-permanent; if your remap is bad, you'll have to take your car back to the manufacturer to gain access back to the existing file, for a hefty price.

  Is this product safe for my vehicle's engine?

Yes. Unichip Europe pride themselves in developing remarkable tunes at no cost to your engine's integrity OR mechanical components.

  Will this product leave any trace on my engine?

No. If your car is under warranty or kept through a hire purchase agreement, you can rest assured that all Unichip Europe tuning kits will not tamper, change stock/existing ECU files or leave any footprint on your car.

  Are your products adapted for my vehicle?

Yes. Every single Unichip plug and play kit has been tuned on the exact make / model that you're purchasing, on our in-house rolling road by our expert tuners.

  Is this product easily removable should I wish to?

Yes. Simply unplug and remove the kit from your engine bay / ECU location, plug in your vehicle's stock ECU wiring loom, and it's like we were never there.

  How long do your Plug and Play kits take to install?

As a rule of thumb, the majority of our kits take 30 - 45 minutes to install. Most vehicle ECU's are relatively easy to locate. However, some are located underneath / behind the glovebox. If this is the case, we'll provide instructions on how to easily remove the trim with generic tools.

  What are your Exchange / Returns / Shipping Policies?

If you're not completely satisfied with your product, you've got 30 days to send it back to us to receive a refund. The bespoke nature of our plug and play kits implies that exchanges aren't applicable. Please ensure that you've correctly identified your engine code and checked your existing ECU connections / ports and cross - reference them to our images provided. There will be a handling fee for any incorrect purchases. Don't hesitate to get in touch with us if you're unsure; our small workshop team have all been part of the development process, and know these vehicles inside out! There is a shipping fee incurred with all of our products, which will depend on your location. You may find out how much this is during the checkout process (don't worry - it's before you submit your order!). We aim to have your kit assembled, uploaded and quality tested between 3 - 5 working days. All products are sent by a fast delivery courier service.

  Does this product come with a warranty?

The Unichip Module itself comes with a 5 year warranty. The quality of the build and the nature of the product means that only 1/400 Unichip Modules are faulty, as pre-determined by Unichip HQ in South Africa. Currently, there is no warranty waiver for the Unichip wiring harnesses. However, we can assure you that every harness is tested and quality checked for any faults before the product is shipped. Unichip Europe pride themselves in not only creating the best driving experience for you, but maintaining this experience for years to come. If you've got any questions about assembly or build quality, please feel free to contact us and we'll talk you through it.

They're not only different from each other - they each have a real world benefit designed to increase vehicle security, drastically improve fuel economy, increase towing / off-road capability and deliver an unparalleled performance map.
