J's Racing ECU's and Tuning

J's Racing Hyper ECU's can be tuned to match modifications and upgrades made to your car. For this service you will be required to send us your ECU so that it can be sent to J's Racing for flashing; they will not open or disassemble your ECU.

If you have custom engine work such as cams, higher displacement or compression ratio then please contact us before ordering. They will be an extra charge if you wish for the ECU mapping to reflect these changes.

When ordering, please use the order notes field at checkout to specify your ECU requirements and vehicle modifications that will affect this (air intake, exhaust etc).

WARNING

If a dealership updates your ECU then you will lose your custom mapping.

We are not liable for any damage caused as a result of the ECU mapping. 

Please ensure you understand the properties of this product before using.
