Dear Yeti Fans,

 

I finally took the plunge and tuned my Yeti. I considered getting a proper rolling-road tuning in Ireland, however they're few and far between over here and some of the places I contacted for a basic remap didn't have the remap for a DFSB engine.

 

I opted for a TDI Tuning box from the UK after watching far too many YouTube videos and asking on FB Yeti forums for advice as the engine code is DFSB and not a C*** variant. I paid €358.82 (€281.33 for the device (20% off) and €47.50 for BT Connectivity), and sadly due to Brexit I had to pay a duty with admin fees of €101 on top of that for a total of €459.82. It's a lot of money for a gamble, however, a gamble that paid off.

 

The box arrived only a week later with instructions, and while they were clear they weren't for "Dummies" clear. I know the front end from the rear of my car and I that the steering-wheel is at the front... 🙂  Therefore I've added a few photos with instructions for those not mechanically inclined, like myself.

 

Box with the device, the cables, and instructions:

 

The cables, with two connectors: the fuel injector and the booster:

 

Device and cable laid out on top of the engine compartment:

 

Remove the engine cover, starting at the top left or right corner (snaps) then the lower corners (laid out the instructions to aid me):

 

The Booster Connector (connects to the blue TDI Tuning connector), it has a locking mechanism that needs to be released before unplugging (on the top of the connector, pull up, lower right of this picture):

 

The fuel injector connector (connects to the Green TDI Tuning connector), locking mechanism is on the other side, and must be released before unplugging:

 

Connect the TDI Tuning connector to the Booster of the engine, and the Booster connector to the TDI Tuning cable:

 

Connect the TDI Tuning connector to the Fuel Injector of the engine, and the Fuel Injector connector to the TDI Tuning cable:

 

Disconnect the plug and connect your TDI Tuning device (it only fits one way, though take a look before trying to plug it in, and lock it):

 

 

 

Start the engine, and check the dashboard for any warning lights, followed by checking the lights on the TDI Tuning device:

 

 

Download, install, and connect your TDI Tuning app (only if you bought the BT connectivity) using the last 6 digits of the TDI Tuning's serial number (on the actual connector of the TDI Tuning device):

 

Snap the engine cover back in place, being careful not to trap the TDI Tuning cables underneath. Route and fasten your TDI Tuning device and cables. I ran the cables around the front of the engine cover and placed the TDI Tuning device in front of the battery (not shown):

 

Please don't hesitate to drop me a note or a question on installation or placement.

 

What are the pros and cons?

+ It's easy to install and remove (NCT/MOT and at service).

+ It doesn't permanently modify the ECU.

+ Can lower fuel consumption, and definitely improves performance.

+ When I change car in future I can send the device to be reprogrammed by TDI Tuning for the new car.

- Doesn't provide the same potential gains as a rolling-road update/remap, or a stock ECU update/remap.

 

What's it like?

I'm driving at the middle setting of 4 (190 BHP, 400 NM Torque) with a noticeable difference in power and performance. I've yet to drive far enough to gauge the change in fule consumption, and I've yet to try the other settings (7 = 195 BHP, 420 NM Torque). From a rather zippy 148 BHP and 340 NM Torque to 190 BHP and 400 NM Torque is good, and a clearly noticeable difference.

 

Sláinte! 🥃

Added an additional benefit, reprogramming of the device when I change car.

I like the fact you can get it reprogrammed for another car. That's pretty cool.
