Anyone try the new Renntech ECu
Yes this looks interesting. My X6M had a HHT from Velos designwerks, and it was great. It made it easy to go back and forth from tuned to stock. Here is the link for the Renn:

So when you receive the tuner, it's ready to go. No need to download a software to your computer, load the tuner, etc.
When you receive the module, make sure the toggle switch is set to tuned, car in key position 2 and then plug the module in your OBD2 port.
The little LED turns red and starts loading. After about 2 minutes the LED turns green and the process is done.
You can now unplug the module and you're good to go.
If you decide you want to go back, just repeat the process with the toggle switch moved to stock. You can switch between tuned and stock as often as you like.

We still can do customization. But if not noted/discussed directly, it will be our highest power ECU Upgrade.

I got my OETuning tune for $1,300 all in with the device. Is there a Eurocharges/Renntech tune out there with 25hp more? Probably...
