Im going to ask my GTR builder friend if he has had similar issues with his builds.

My friend said it's common on the GTRs also

I’m tuning my car using EcuTek and I’m trying to use the cable to upload a calibration. But I’m not able to due to an error screen. The bt function is work but not through the cable. The unit will not connect to the ECU. The error code is ProECU 6CE5D2 Timeout waiting for response (EVI)

I've not noticed any issues with the Ecutek Dongle or key range... Nothing but a positive experience so far...

Actually, just posted this review...

Curious to hear other's experiences.

Your Bluetooth interface may need the firmware updating. Try to use the stand-alone updater tool, plug the Bluetooth interface module into a PC with the supplied mini USB cable and run the updater from the link below, the PC will require internet access to do this.

Just searched for why my FOB's range was suddenly reduced. ECUtek BT Dongle is the culprit here as well!!

Guess they're not going to fix it.

It's absolutely horrible with the dongle plugged in. :shakes head:

I hate it. I never leave mine plugged in as a result. I spent several weeks thinking it was my fob dying, couldn't figure out why switching batteries did nothing.

Does the EcuTek bluetooth dongle have an FCC ID printed on it?
If it does either post it or PM me.

If it doesn't, then I suspect noise from the EcuTek dongle (not in the 2.4 Ghz Bluetooth frequency, but in the 315 MHz key fob frequency) is reducing the range of the Nissan fob.

No FCC ID# It does say BT 1.0

Same here, I take mine out all the time.

Wow...I was actually considering purchasing the BT Dongle but after reading this IDK ����*♂️

Prior to the ECUTek piece I had another brand BT Dongle I used with Torque App. ZERO interference of this sort so it's possible for ECUTek to fix if they cared enough.

If you're not going with the BT you're forced to plug a USB cable into whichever device you're going to broadcast info on. From what I've experienced thus far, the BT dongle allows wireless for everything except for uploading a new map.

To upload a map with the BT you use the removable USB cable. Basically you're getting the standard wired cable option as well as wireless when you use the BT.

Ecutek does care, and a fix is in the works.
