Cheerful, professional, service. Excellent value for money

After visiting Nissan garage (I have a Nissan Juke), I had no other option than to replace my radio (problem with the screen and radio code issue) price over 700€, the employee told me before quitting the garage, “have a look at KC SYSTEMS” , I did it and met Mr D the same day , for less than a third of the price for a new radio, he did a fantastic job and my radio was working perfectly the day after. Very nice person and most off all efficient and very professional , thank you Mr D

Hi Donal,

Many thanks again for your advice and expertise and patience in resolving the issue with my BMW idrive head unit, and for such a reasonable rate,
I really appreciated your responsiveness and customer oriented service. Very happy that I have access to the on board computer, stereo and Bluetooth again.
Thanks so much again, I never thought I’d be able to resolve this.

TOP JOB !!

I own a Ford Focus hatchback and around a week and a half ago all the warning symbols started to light up on my instrument cluster. So then I took it to my garage and they plugged it in to diagnose the problem and it showed up I had a instrument cluster problem. I was told to contact donal in KC Systems and donal also told me that the instrument cluster problem was a known issue with the Ford Focus. Then I got a courier to get it up to donal and to my amazement he had sorted the problem in no time at all. I would highly recommend donal to anyone as he really offers a very prompt service. And to top it all off donal is a real gentleman and if I ever had a problem again I would be using donal again. Thanks a million donal and continue to keep safe you and your family.

I went on the recommendation of a motor camper van club to have my my new VW camper van remapped . It pulls strong and cleanly through all of the gears , I was surprised at the improvement and am very happy with the results thanks KC .

great job . for remapping cars , KC SYSTEMS is simply the best .
Donal remapped 3 cars for my friends & me yesterday .

Donal delivers everytime with every car I send him .
a true professional in his industry !

Highly recommended company.
My Ford Focus mk2 ’07 Clock Cluster was throwing up all sorts of faults and causing the car to go into immobilizer mode. Garage quoted me €850 plus vat for a replacement. Dropped the cluster to KC’s lunchtime Monday and got confirmation it was repaired teatime same day – at a fraction of the cost. Everything working perfectly since repair. Thanks KC

Delighted with this companys work .
Dropped my 2013 focus with a faulty radio into Donal early in the morning . He kindly dropped me into the village where i got a bus to Cork city . Had a few hours shopping done when Donal called to confirm my radio was fixed . He collected me again from bus stop .
Excellent service from a very nice guy !
Top marks to KC systems

Excellent service from Donal.
I got my Volvo S40 performance remapped by him. Instant difference on the drive home from Cork to Limerick, it felt like a different car!
The ability to overtake in a safe manor has increased greatly whilst also maintaining comfort.
Delighted with the professionalism, service and results!

Thanks Donal!

professional & quality service !
dropped my Audi into Donal for a remap ……..OMG ! what a difference ……..
car is transformed into a new machine ……..smooth delivery of power right up through the range . torque is dramatically improved & can see economy improved already 24hrs later .
Donal runs a very professional business in Watergrasshill and I would recommend him for remapping from my experience .
top class *****

so so impressed went to a waste of time in sligo told me he could not fix the module and to get a new one and he would fit it at 250 euro so i went to google and found these crowd spoke to the man who told me post it to him posted it on the Friday was back to me Tuesday morning for only 70euro and knew exactly what i was on about. id use them again and again dont use cowboys use these as they are the real deal

Absolutely delighted with the improvements in my E200 after the remap today. Accelerates away effortlessly, instead of revs going up and waiting for the speed to increase it now just goes. The difference is black and white. Loving the extra torque too. Donal is also a nice guy to deal with, knows his stuff and listens to what I wanted and simply provided it . Fantastic guy to deal with.

Delighted with KC systems quick & professional service. Problem with dash fixed & car back on the road. Thought there was a problem with the immobiliser but once dash sorted all fine again.Would definitely recommend.

brillant service,sent my radio down to get recoded and had it back in a few days going perfect,very satisfied customer,john co Donegal

The potentially very expensive fault with my Disco3 radio was quickly identified, and, following a suggestion, I found a replacement in a breakers’ yard. The internals of this were fitted for me – all at a very reasonable cost. Highly recommended!

Posted my digital dash that was totally blank to kc systems on Wednesday and got it back on Friday fixed and working perfect. excellent service keep up the good work 👍

Very happy with the results of the remapping service. There is a noticeable difference in low down torque and far greater mpg figures.
I’m so happy with Donal’s services that I’ve just booked my wife’s car in also.
Delighted I didn’t opt for the cheaper off the shelf maps that so many others are selling.

using KC systems for several years now . we send them all our Airbag ECUs for resetting .
top class service every time !
keep up the good work Donal

excellent service !
had trouble with my cars ECU . Donal advised me to source 2nd hand as original ECU are so difficult to repair . sent both ECUs to him to transfer information . he sent back both ECUs within 24hrs . fitted 2nd hand ECU and car started first time ………..running like clockwork since .
KC SYSTEMS saved me hundreds on a new ECU .
cannot say enough about this guys advice & honesty about the job at hand .
5 stars *****

thank you Donal
greg in Wexford

Rang kcsystems at 4 today and got thru to a lovely lady to say she text me directions by text dropped the key off at 4.30 and had it back by 5.10 and key worked first time and cheap as well thanks a million

my Megane would not start . was getting message of card not detected . found KC systems online and rang them . they said they could repair within 1hr ! called to theyre workshop in Watergrasshill and within 50 minutes my keycard was fully repaired . started my car 1st time when I returned .
great service !

brillian service. prompt and punctual

dropped my van in to be remapped . 2015 ford connect . great job . made a massive difference in power and smoother drive . saving about 5mpg since . nice guy to deal with aswell . thank you Donal

I brought my 2005 Honda CRV 2.2 CDTI into KC Systems in April. Its standard configuration was 140bhp with 340nm of torque.

Donal remapped the ECU to 175bhp with 400nm of torque. The engine was instantly transformed!!! Power is available through a much wider band than before making for a much more pleasant driving experience. Overtaking is more relaxed and fuel consumption is improved due to the engines ability to pull in higher gears at lower revs.

I would highly recommend KC Systems and i will definitely be back the next time i change cars for a remap. Don’t waste your money on cone filters or new exhausts. If you want more power, get it remapped by the professionals.

coded my Opel radio within 20mins . saved me a small fortune on buying a new one . top class !

very pleased with this companys service . was badly stuck Friday afternoon as my Laguna would not start . rang KC systems who advised the keycard was most likely the fault . they repaired my key within 50 mins of arriving to their workshop and I was mobile again that evening .
would highly recommend this companys service .
thank you
