9. PrecisionCodeWorks ECU Remapping & Tuning Software

If you don’t have much experience with ECU or chip tuning, or you don’t have the time to do the coding yourself, PrecisionCodeWorks is the car software you need. This tuning software makes ECU remapping simple and straightforward.

Simply read the original ECU files and upload them, select the modifications you want, and then PrecisionCodeWorks will send a new build to you straight away.

They now have a client database of more than 3000 users, supplying more than 1000 calibrations every month. PrecisionCodeWorks technology eliminates the possibility of errors and it’s live 24/7, every day of the year. No other providers can create files that are automatically read to flash.

One of the downsides of PrecisionCodeWorks is that you have to buy credits to use it. With every new build, it’ll cost you credits so it’s not a very economical system if you’re working with several vehicles.

The build options are also limited – PrecisionCodeWorks doesn’t allow you to alter the tables yourself. Ultimately, this software is better suited to hobbyist tuners rather than professionals. Although you don’t have as much freedom, there’s less chance of you making mistakes with the ECU.

Car Tuning Software FAQs:

Can I remap my ECU myself?

Yes, if you’ve got the correct tools. All of our reviewed car tuning software allows you to remap your ECU. However, ECU remapping is a complicated process and it’s not advisable to attempt it unless you’re 100% sure what you’re doing.
Consider the ECU map as the instructions for the engine. Lots of parameters are precisely stated in the tables, deciding the air-to-fuel ratio, spark timing, and other vital engine procedures. If you’re not sure what you’re doing, you risk causing serious and irreparable damage.
You can find lots of guides online, specific to each vehicle, that will explain the best methods for ECU remapping, as well as guidelines for EGR and DPF. If you’re not familiar with engine coding and car tuning, it’s strongly advised that you read through one of these guides before you get to work.

What is the best ECU tuning software?

This completely depends on the car, van, or any other vehicle in question. It also depends on the ECU as well. You need to take into account whether you have Windows, Mac, or Android as most software only works with certain programs.
An OEM ECU usually relies on software from independent companies for specific tuning. Most tuning these days is done through the OBD port using a handheld packed with off-the-shelf calibrations. These can be connected to a laptop to create customized tuning calibrations.
If you’re working with a totally custom setup and you’re replacing the manufacturers ECU, Haltech, MoTec, and MegaSquirt are good options.
If you own a garage, and you’ll be working with multiple vehicles, Quantum Tuning offers software that has three options. This means you can re-tune diesel, gas, and hybrid cars, making the software incredibly versatile.

How do you learn ECU tuning?

If you’re serious about tuning your car, the best thing to do would be to take an ECU tuning course. There are courses available in many different countries and you’ll be given professional instruction on successfully tuning an ECU.
The first thing you should learn is what ECU tuning and remapping is. It’s when you alter the settings and different parameters of the ECU in your car. This is done to optimize and improve them to create your ideal performance.
It’s commonly done to increase the fuel economy, the engine’s power and handling, and other things such as the removal of a speed limiter.
You can also learn the art of ECU remapping by searching online. There are lots of resources that you can take advantage of, as well as many books on the subject if you enjoy reading.
Another thing to remember before you throw yourself into ECU tuning, is you need to know the fundamentals of how your car works. Trying to perform something super technical such as ECU remapping before you learn the basics, is a disaster waiting to happen.
