Description
We are the main innovators in this platform. Our team bent over backwards to acquire one of the very first Blackwings in North America, serial number 0026. We started working the day the car arrived, and have been developing a proper tuning solution for these cars over the last year. Our flagship CT4-V Blackwing already has 12,000 miles, 320 dyno pulls and 716 whp. It has been the drag strip seven times, racing in events from Florida to Texas to Ohio.
The JB4 Tuner attaches to easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. When you combine this with our custom mapping, it will allow us to safely increase the power and boost levels of your CT4-V Blackwing.

CT4-V Blackwing: JB4 Tuner
Yes, all driving modes will work the same as they do now. Below 3,000 rpm, the car will feel completely stock in all modes. Above 3,000 rpm, you’ll have more boost and power than before.
The JB4 does not change any factory ECM settings. So you can easily remove the JB4, leaving no trace behind.
No, we still don’t have ECM access, so there is no way to disable DTCs or eliminate Check Engine Light with aftermarket downpipes yet.
There is no way a dealership would be able to detect the JB4 had been previously installed.
RR12YS or RR12S will work fine. RR12YS may last a little longer. RR12S will perform a little better.
Yes, we pre-gap them to .027”. However, the gaps should be double checked prior to installation.
We will include separate calibration maps for 91, 92 and 93 octane. You can switch between them in very easily via the JB4 cell phone app.
We’re still working on finalizing all the details for our Purple and Brown Belt Performance Packages, which will run E85 fuel.
You can deselect any items you already purchased when you place your order.
You can install it yourself, or you could bring the car to our shop here in Ohio if you prefer.
https://www.tapouttuning.com/frequently-asked-technical-questions-for-ct-4-blackwing/We have not tested the JB4 tuner in extreme temperatures. However, we have tuned the same LF4 engines in hundreds of ATS-Vs all over the world. Many are in Dubai, and that’s one of the hottest regions in the world. Plus, the CT4-V Blackwing has a significantly improved cooling system. You can learn more about that HERE.
They are completely distinct products from different manufacturers, with different electronics, different software, different sensor taps, different user interface and different custom tuning ability. The only thing they have in common is that they both allow the cars to be tuned outside of the ECM.
We have been working on our in house dynamometer, and have completed 225 full throttle Blackwing pulls to date. We have spent considerable time and effort testing and validating the JB4 product for the CT4-V Blackwings, and are currently developing and refining their calibration maps for the perfect combination of increased power, while still retaining safety and reliability. Other tuners who haven’t done the proper testing may elect to turn the knobs up higher than we do, but they don’t really care about the longevity of your engine.
If you want to create your own calibration, you can use Map 6 and edit via your cell phone app.
Don’t worry. We can take care of your engine replacement on site 😉
We’re working on it right now, but cannot give a precise E.T.A. at this time.
When you’re not in the gas, the tunes will perform identical to stock. So the car will still be totally fine on long road trips.
Bolt-ons do not typically increase horsepower for untuned CT4-V Blackwings, since the ECMs are torque based. If you install something that helps the engine to flow more air, the ECM just commands a little less boost, and power output remains the same. This is why all our CT4-V Blackwing Performance Packages include both parts and tuning.
