ECU Remapping or also known as Software Upgrades, done correctly, will always be the better and safer way of optimising an engine. Much more parameters can be optimised than a with a chip. A Chip will ultimately only fool the Engine Control Unit (ECU). For example, most chip options will connect to a diesel engine’s common rail pressure sensor. The chip will intercept the signal providing the ECU with the rail pressure values. The chip will reduce the common rail pressure signal by a certain percentage, thus fooling the ECU into thinking the common rail pressure is too low and by this method, the rail pressure is increased. More fuel is injected and that is how the additional power is achieved.

With ECU Remapping / Software, the ECU is not fooled nor tricked. The software directly instructs the engine and components what to do. With ECU Remapping a lot of small changes are made to make a significant difference safely instead of the 1 or 2 parameter changes made by a chip. With modern ECU’s it becomes more and more difficult to fool or trick ECU’s with a chip. That is why in some cases little or no additional power is achieved or engine malfunction lights will appear and the vehicle will enter safe mode or also knows as limp mode.

In a few cases some may argue a chip made more power than with ECU Remapping, this is not because no more power can be produced with ECU Remapping, it is most likely decided by the developer of the software that any more power will be unsafe for the engine or the skills or the developer may be limited.

In rare cases, some vehicle’s software can not be optimised because of the limitations of the interfaces that is responsible for reading the ECU’s software and after optimisation, the writing of the new optimised software. In such cases, a chip is the only way to increase the performance of the engine.

Plug & Play Units does have an advantage when it comes to vehicle warranty. In most cases, if the unit is removed before service, it is undetectable by the manufacturer. ECU remapping / Software Upgrades may be detected by some manufacturers, this, however, happens very rarely. There is still to this day manufacturers that can not pick up the ECU Remapping / Software Upgrades.

With regards to vehicles out of warranty, ECU Remapping / Software Upgrades should be your first choice.

The only advantage any chip(Plug & Play) will have vs ECU Remapping is the warranty factor. Companies claiming that a chip is better than ECU Remapping is purely trying to trick you into a sale because they don’t offer ECU Remapping.

    Does the remap include changes to the automatic transmission?
    Do you have an office in or near Cape Town?
    Regards,
    Willem

    • Good day Willem,

      It will cost R3500 Incl Dyno Before & After. Gains are usually in the region 20-30kw & 70-100nm. No, we do not change the transmission settings. Unfortunately, we are only in Gauteng.

    • Hi Chris, usually about 30kw & 100nm on the wheels. I will soon post a video of 3.2 that we have recently done.

  11. I recently had unichip Q4 fitted on my Mahindra xuv500 2012 model. I am not satisfied with the results .e g. My fuel consumption shows 18 kmpl avarage on the screen, but when I physically calculate it with the total fuel used and covered kilometers I get just under 13 kmpl. I am thinking of having the chip removed and software update done. Is this the better option or what can be done? And what will be the cost involved?

    • Thabo,

      Yes, we can do ECU Remapping. It will be the better option.

      We need the vehicle for a day and it will cost you R4500.

  12. Good day,

    I am considering a ECU remap on my 1.6 tdci Fiesta 2014. Can you maybe give a estimate price on that?
    Are you guys only in Gauteng? Thank you

  13. Hi am in Botswana I own a Mercedes Benz C220 CDI from UK, I need DPF delete + ECU remap for increased power. How much the cost for this.

  14. hi I have a 2007 mazda bt50 crdi 3.0
    115kw 380nm will it be worth it to do remapping , and what will the gain be in power.
    and will it effect how many km you have on the clock?

    • Keith, yes we can upgrade the power. It will cost you R3000 and we can add 24-28kw & 70-90nm of additional power.

  15. Hi
    I have a bmw 320d E90 2005, I want more power and perfect fuel usage. Any suggestions, price and how it will affect the gearbox and engine?

  16. I have a Landcruiser V8 4500 double cab with unichip. Will it change much to remove and do mapping and what would the cost be!

    • Herman, yes we will be able to improve the performance. It will cost you R3500 and we need the vehicle for 3-6 Hours. Go to Dastek and get a bridge plug if you do not have one. This will enable us to test with the UniChip installed and then disable the UniChip to do a comparison between the remap and chip.

  17. Hello
    I have a 2015 Ford Focus ecoboost 1.5
    Would you be able to do mapping on it and what would the cost be,and expected power increase?
    Kind regards

  18. Hi. I am looking at either a plug and play option or remapping for a 2017 Toyota Rav4 2.2 Diesel (110kw/340nm). As the vehicle is still under warranty please advise if any options are offered on these vehicles and what the cost thereof would be? Thanks

    • Good day, we only do ECU remapping on those engines. There are too many issues with the plug and play systems. A remap will cost you R3500 and we need the car for a day.

  19. Hi,

    I have a ford kuga 2.5T AWD Titanium 2012 and would like to know how much for remapping and how much gain will i get in power & torque?

    Thanks,

    • Denzil, a plug and play unit will have little to no effect. ECU Remap is the way to go. We need the car for 4-8 Hours. The cost is R3500. Gains will be in the region of 20-25kw & 40-70nm.

  20. Hi
    I have a 2012 Lexus LX570, it has a Unichip and performance exhaust, but it is still quite heavy on fuel. I don’t think the chip made any difference. What would you suggest is the right way to go.
    Would a remap be better ?
    Regards
    Mike

    • Mike, in our conditions here in SA, there is no point in trying to tune naturally aspirated petrol engines in most cases. Not worth the money at all.

  21. Good day

    Hope you guys are doing well

    O ja and HAPPY NEW YEAR !!!

    I want to ask is it maby possible for you to PLEASE send me a result of a 2.4 GD-6 2017 Hilux so that I can see the difference between stock and when it has been remapped and also for the different types of remapping you guys can do in terms of the different powers available.
    I want to compare it so that I can see what map to choose

    I don’t have FaceBook anymore because they tried to hack my account so I then deleted mine so if you don’t mind to please mail it for me

    I will REALLY appreciate it ๐Ÿ˜€

  22. HI

    I drive a 2017 Polo R line 1.0 DSG and i installed plug and play chipbox in my car. When i leave my car idling for more than 4 minutes , the engine flashing lights displays (flickering) which causes me to switch the car engine off; and also the engine flashing flickers when am I driving up an incline and i have to follow the same procedure again.

    What is the cause of the problem ? And is it advisable to change to Re-map?

    • Good day, simply remove the chip and all will be ok. Remap is the better option, yes, but we do not work on Petrol engines.

  23. I have a BMW 330d F30 2016 model. Whatโ€™s the best way to increase power? And please advise on cost if you are able to do it. Car is still under motor plan. What gains can I expect?

    • Good day, ECU Remap is the way to go. R3500 is the price and we need the vehicle for a day. Assuming we are talking about the 190kw version, gains will be in the region of 25-35kw & 70-100nm.

  24. Hi how can u help me with best performance and power on a Volkswagen polo trendline 1.4 2016 model and the price I’m from pretoria

  25. Good day we have a c250 cdi 2013 merc. We had the dpf removed and egr blankt off and the ecu was remapped to delete the components that was removed. The car goes well but when you accelerate there is heavy smoke. The kilos is 65000km. There was no smoke before the components were removed. Suggestion please I am ashamed to drive with the car

    • They probably tuned the vehicle for additional performance and did not do a very good job of it. Ask them to remove the tuning. Or something else is wrong with the engine.

  26. Good day.
    Got Infiniti 2016 Q50 2.2d and Iโ€™m away from SA ๐Ÿ™‚ so can ECU remapping to cancel addBlue and EGR be sold online? Any hardware needed? If yes can it be DIY if you will provide procedure?

  27. Good day. I have a 2017 Toyota 2.8 A/T 4X4 with 100k km on the clock. How much power gain will a remap give, and how long will the process take to remap?

  28. Good day. I have a 2019 Mitsubishi Pajero sport 4X4 with 8000 km on the clock. How much power gain will a remap give and what is the price?

    Kind regards
    Henry
