    Unitronic ECU Tune

    Posted by Howard on 9th Mar 2023

    I was looking to boost the performance of my Audi A4, and after WCT's recommendaton and doing some research, I decided to go with the Unitronic ECU tune. I specifically wanted more response and a more consistent delivery of power, and this tune seemed like the perfect solution. I opted for the Stage 1+ tune and the Uniconnect+ cable, which made the installation a breeze. The application walked me through the entire process, and I made sure to have a constant power supply to my car and laptop, turned off all accessories like the radio and heating/cooling. I had no issues installing the tune at home which took about 15 - 20 mins. The results are beyond my expectations. The power delivery was much smoother, and I noticed a significant improvement in throttle response and shift smoothness. This was my first time investing in a performance upgrade, and I am thrilled with the results. One of the reasons I chose the Unitronic ECU tune was because the company is Canadian, and I thought their tune would be better suited for the weather conditions here. I can confirm that the tune performs well for me in the Canadian winter, and I imagine it would be equally suitable for similar conditions in other regions. Overall, I'm very happy with the Unitronic ECU tune. It was easy to install, and the performance gains exceeded my expectations. If you're looking to improve the performance of your Audi A4, I highly recommend speaking with the folks here and giving this a try.

    Thank You Long! Ordered and received within a couple of days. Installation was simple and slick - no issues. Unitronic has a great app that walks you through the whole process. My car is stock with a resonator delete (purchased at WCT). Went for the Stage 1+ tune with the Uniconnect+ and was able to flash the car at home. The flashing process took about 15 mins. Car stumbled a bit on 1st start up - likely due to new programming and the ECU executing adjustments. Took it easy on a 10 min run around the block. Next Day: Started and let the car come up to temp (March). Then headed out for coffee. Probably was the first time I drove the car in regular Drive mode. Didn't really notice any big changes. Switched into Sport mode - which is what I usually drop into all the time. Holy!..... car has an attitude. This is a different car now and the smile on my face grows with each run. Gone are the runs where the car felt like it was falling on it's face. Shifts are smooth and the pull is much more aggressive and consistent. 'Snappy' come to mind when describing the ride. Very happy with the results - having fun!
