Highly Recommended. I had Brno tune my brand new DMAX 2025. While it was a bit tricky being a brand new model, he went above and beyond to ensure everything worked perfectly. Amazing service!!!!! Now the DMAX is in beast mode, with amazing performance.Posted on Google![]()

So…… it’s about time this story be told. I see myself as a pretty typical kiwi bloke. I have goals and dreams, a whole heap which are vehicle related!! I was lucky enough to purchase a couple of ‘dream vehicles’…. They did everything I asked of them, but in a pretty underwhelming fashion. I live on a farm, do a tonne of towing and travel distance daily. My Landy got all of these done, but you always felt it had more to offer. It turns out my phone was listening….. low and behold an add appeared to which I made an enquire. Long story short, I explained my situation to Bruno….. to which he said, “I’ve got you”. Within the week he had a prepared a new map specific to my needs, one quick meeting to transfer a file and done. The truck was an entirely new experience. The dream truck performed as it should!!! From then, I’ve had multiple vehicles tuned by Bruno. All of which had different configurations…… each time with specific needs. Bruno is very thorough and on more than one occasion has requested I change /service / monitor components so they enable the tune to function as it should. I have always trusted this advice and because of it, have had many years of trouble free motoring. He went above and beyond early doors, even organising a dyno for my 110 TD5 defender “The Rhino” to show exactly how the performance was enhanced. More recently I had an experience where my EGR gave up in my 110 Puma (Grey 110). The computer sensed this and put the engine into limp mode. I contacted Bruno as my mechanic said we could essentially have the EGR blanked by having the computer command the valve to stay closed. Bruno, true to form went out of his way during an incredibly busy time of year to re-tune the truck. A flying visit was all both parties could manage given it was new years eve!!!! But in that short time Bruno uploaded the new file, sent me off on a test drive, recognised the issue was still present, then through his experience suggested I unplugged the EGR disabling the computer’s sensor. Problem solved, I couldn’t believe the power that was set free!! New year’s road trip saved!! Mate, you continue to amaze me with your talents. The performance, fuel savings and all around drivability gained from your services are most appreciated. I look forward to future projects and to prospective clients I cannot recommend this team highly enough!! More than happy to chat through my experiences as I can assure you it is a game changer.

Had a stage one done on my 2018 CX-9 2.5T. Unbelievable difference. Loads more torque, power and acceleration, super smooth too - and - the team went out of their way to fit me in pre Christmas - awesome all round. Absolutely terrific. 5 stars all day. (THE BEAST courtesy car was a bit of fun too).Posted on Google![]()

I Collected my 2021 Isuzu Dmax today from Brno. I am really happy about the result. The tune has transformed the driving experience imo, turbo lags is gone, the expanded torque range is great, I can have my 6th gear back, motorway overtaking is much improved. It's really really nice to drive!! Thanks Brno!Posted on Google![]()

Just had my 2019 Mondeo stage 1 tuned by Brno last week. Instantly notice much improved throttle response, and the turbo lag is gone, generally smoother ride. Thanks so much!!!Posted on Google![]()

Thanks to Brno my Mercedes c320 has been rejuvenated. Despite it's age of 2001, Brno has brought out the hidden potential of an older engine trapped by factory settings with no aftermarket hardware needed The feeling of a more responsive motor with more grunt is a joy and due to the skill of Brno it didn't take much time to achieve. I wish I had more cars for him to do his magic on. Definitely Brno is the man to go to for engine firmware tuning. Adrian T. Wellington.Posted on Google![]()

New OBD protocol for Continental GPEC4LM ECUs – Stellantis.
KESS3 and Powergate expand support for Abarth, Alfa Romeo, Citroën, Dodge, Fiat, Jeep and Peugeot petrol and hybrid engines.
With this update, KESS3 (and Powergate) allow you to work via OBD on Continental GPEC4LM ECUs, directly through the diagnostic port, to read and write the engine control unit, reducing the operations required to access the ECU and making the reprogramming workflow faster and more immediate.
The new protocol complements the already available BOOT mode and supports petrol and hybrid engines such as the 1.0, 1.3 FireFly, 1.5 48V Hybrid, 1.5 48V Hybrid VGT and 3.6 V6 Pentastar, fitted to city cars, saloons and SUVs produced from 2016 to the present for the main international markets.
The real benefits for the workshop:
– Reading and writing through the diagnostic port
– OBD or BOOT operational flexibility across different engines
– Faster ECU management
– New opportunities across the main Stellantis and former FCA brands
– OBD management also available with Powergate
– Possibility to work remotely on the customer’s vehicle
This new support allows workshops and tuners to work more flexibly on Continental GPEC4LM ECUs, choosing the connection best suited to the vehicle and the required operation on an ECU widely used across the latest Stellantis range.

New BENCH protocols for MDG1 “Locked” ECUs with KESS3.
Read and write protected ECUs directly from the connector after unlocking with KESS3 Unlock Module.
KESS3 increases speed and safety in the workflow dedicated to Bosch MDG1 “Locked” ECUs, introducing new BENCH protocols that can be used after the unlocking procedure.
The development covers Bosch ECUs already supported in BOOT “Unlock” mode: MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 HW80, MG1CS031, MD1CP006, MD1CS005 and MG1CS002, installed on a wide range of petrol and diesel applications from 2021 onwards.
The first step is to unlock the ECU: using the Unlock Module accessory, access the ECU and perform the BOOT unlock procedure, applying the required patch. Once this is done, you can connect directly to the ECU connector and work in BENCH, without having to open it again.
The benefits for everyday workshop operations:
– Unlock protected ECUs directly in the workshop
– Direct access in BENCH after the unlock
– Complete backup of ECU contents
– Greater operational continuity on latest-generation cars, LCVs, heavy-duty vehicles and tractors
The new protocols are available to KESS3 users with CAR BENCH/BOOT activation and an active subscription. The KESS3 Unlock Module is required to perform the BOOT “Unlock” procedure.
