ECU Remap for a 7% Improvement!

You send us your ECU and we'll have it remapped with a copy of our dyno tune to gain 7% more power.

about this tune are in this post: https://jimny.co.nz/blogs/build/now-with-7-more-power.

You need to send us your ECU, which we will update and send back to you on an overnight courier. We only need your ECU for about 24 hours, so you're not without your car for too long.
