Tapout Tune of the Week!

For many customers tuning is a completely new experience. We understand how important your ATS-V is to you and we don’t take that responsibility lightly. Our number one concern is tuning your car safely and everything we do is completed with that in mind.

In today’s Tapout Tune of the Week, Kyle from New Jersey had recently purchased his ATS-V and was hesitant about tuning. He had never done something like this so he wanted to make sure he worked with a tuner that had the proper experience for the job. “After talking with Scott, my mind was at ease and I purchased his tune” Kyle said. He went on to say, “Scott has top tier customer service and even higher tier tunes! I will recommend his service to anyone!”

Our goal is always to make sure you are happy with your tune. With our comprehensive knowledge on the LF4 platform we can make your ATS-V the performer you always knew it could be. Don’t settle for the limitations GM thought your V should have, and as Kyle said, “prepare to unlock BEAST MODE on your V!”

Fixing Problems Before They Start!

Why do we force everyone to go through the extra hassle of data logging their ATS-Vs before we will tune them? Because we don’t want to add boost to cars that might already be ticking time bombs. Check out this recent data scan from a totally stock car with OEM tune. In this case the owner had no idea there was anything wrong. This table shows average Knock Retard (KR) by airflow versus engine speed. You can see massive amounts of KR everywhere, because his intercooler was not working at all. This was confirmed by MAT (manifold air temperature) remaining > 180 degrees at WOT (wide open throttle). Having learned this we would never consider shipping out a canned tune that adds four to six more pounds of boost to this ATS-V without first getting the intercooler repaired. By data logging your car Tapout Can identify problems such as this and make sure they are addressed before moving forward. Once the intercooler is fixed, we can start tuning the car.

Tapout Tune of the Week!

After losing faith in the quality of work performed by my dealer’s performance shop, I started to question the safety characteristics of my dyno tune. Knowing several friends that had their ATS-V’s tuned by Tapout, I reached out Scott with my concerns. Before purchasing a remote tune, Scott asked me to send him a copy of my tune and a few logs. Upon reviewing, Scott noted several issues, two of which were alarming.

First, the ECM was not reacting to throttle input appropriately. The screenshot below illustrates a full-throttle attempt 33 mph. However, the ECM didn’t open the throttle to 100% until the car hit 58 mph.

Next, and of great concern to me, the previous tuner completely disabled the knock retard and intercooler protections as illustrated below.

Knowing that my car was not adequately protected, I had hesitations taking it to the track, let alone driving it at all. I immediately decided that the car needed a retune with the safety of the engine being my primary concern.

Within about two hours of purchasing my remote tune, Scott sent me the initial baseline tune. Over one week, I received a total of three tunes that not only left the knock and intercooler protections in place. I felt the increased performance and responsiveness. Additionally, the shift points were dialed in, and my desire to drive the car was at an all-time high.

When Scott announced the introduction of two new features, Lean Cruise Mode and the ability to bypass Cadillac’s max boost limit at startup. I reached back out, and within minutes, I received an updated tune file. I’ll let the log speak for itself. The following screenshot illustrates that at WOT, the air/fuel ratio is within one to two percent of perfect across the board using 93 octane from Costco.

Getting my car retuned by Tapout was by far the investment that I put in my vehicle. And believe me, there’s been a lot of money put into this thing. If you’re new the ATS-V or have a tune from another company, do yourself a favor and send a log file or two over to Scott. You’ll be pleasantly surprised with the results and professionalism that Scott and Tapout bring to the table.

Congratulations to Tim King!

Tim King ran a 10.98 @ 125.2 mph at the Street Car Takeover event in Indianapolis this past weekend! Ten second ATS-Vs are always impressive. This one even more so because he ran tens on his very first pass ever! Tim has a 2016 ATS-V with intake, intercooler, fueling and exhaust modifications, in addition to the Tapout Tune and torque converter. Race weight was 4,080 pounds with density altitude of approximately 2,445′. Stay tuned and you will see Tim near the top of the leaderboard as soon as he gets more seat time in the car and the weather cools down.
