Is a piggyback tune bad for your car?
Piggyback tunes, like the JB4, typically build in additional safety features too. For example, if the JB4 detects dangerously lean AFR’s it will revert back to stock boost in milliseconds. Next, they are incredibly easy and safe to install. Piggyback tunes are generally considered “plug and play” tuning solutions.
What is piggyback in car?
time, American railroads introduced the piggyback car, a flatcar modified to hold as many as two truck trailers in place. Later piggyback-car designs utilized double-stacked trailers on interconnected flatcars.
What happens if I flash my ECU?
ECU flashing, also referred to as tuning, updates the software that runs your vehicle by changing or modifying the vehicle’s memory chip in the ECU. These changes can notably improve your engine performance by improving power, producing cleaner emissions and bettering fuel efficiency.
Can performance chips ruin your engine?
No. A performance chip does not cause damage to your engine or transmission as it increases the horsepower and torque output. This power is generated mainly by harmlessly adjusting your air/fuel ratio and ignition timing to optimal settings. In fact, a performance chip can even protect your engine from damage.
Which aftermarket ECU is the best?
The Best Aftermarket ECU Options
- Motec Motec is the market leader when it comes to ECUs.
- Haltech. While Haltech may not have the same history or prestige behind them that Motec does, their approach to designing their ECUs have made them incredibly popular with tuners and owners.
Can a piggyback tune void warranty?
Your car will be faster with a tune, hands down. However, you will void your warranty instantly. A dealer-lever scan tool will will be able to to detect that the ECU has been tampered with, even if you flash it back to stock.

What does reflashing do to a car ECM?
Like any computer, your car’s ECM has software with different settings or parameters, and these can be changed to alter the performance and driving limits of a vehicle. Reflashing or remapping an engine computer is essentially just the process of replacing the existing software in a vehicle controller with new software.
What happens when you put a piggy back tune on a car?
The piggyback tune isn’t altering any fueling or timing tables in this case. However, more boost generally requires less ignition advance and additional fuel flow. You’re going to run seriously lean if the engine is taking in more air without additional fueling. However, this isn’t the case.
What does reflashing do to an engine controller?
Reflashing or remapping an engine computer is essentially just the process of replacing the existing software in a vehicle controller with new software. Reflashing an ECM is an immensely powerful technique that allows the engine to be tuned in the same way that the factory calibration engineers perform the task. What Is an ECM?
