IMPORTANT This app requires an EcuTek Bluetooth Vehicle Interface to connect to your car's ECU. These are available from EcuTek Tuners. Find your nearest one at www.ecutek.com/dealers. If you don't have an interface, run the demo mode within the app to see ECU Connect in action. ECU Connect is the free companion app to the new pocket-size Bluetooth Vehicle Interface produced by specialist tuning firm EcuTek Technologies. Once you have purchased your EcuTek Vehicle Interface, plug it into your car's OBD vehicle diagnostic socket, pair it with your phone in the app and you will open up a whole new world of enjoyment with your car. With ECU Connect, you can receive and program in a tuned file from one of our EcuTek Master Tuners just with your phone. No laptop, no wires, no fuss. Just create an account in the app, select the tuner you want to work with, and you are ready to receive the tuned file. Discuss with your tuner what you want to achieve from the tune and once the file has been created, you will receive a notification that the file is ready. Go to Program ECU, select the file and follow the on-screen instructions. It's as easy as that. All that's left is for you to enjoy the car! For more details on programming your car’s ECU with ECU Connect go to www.ecutek.com/phone-flash Your EcuTek Tuner can also set up some unique RaceROM features which allows you to control and adjust some aspects of the tune with your phone: Launch RPM; Traction Control settings; boost and torque levels; switch between different set ups such as track mode, economy mode, fast road and flexfuel on the fly. These are just some of the example set ups. Speak to your EcuTek Master Tuner and discuss with them what you'd like. There are lots of options to choose from. For a list of supported models together with their ECU Connect Features go to www.ecutek.com/ecu-connect Whether your car is tuned on EcuTek or not, with ECU Connect you can instantly see how your engine is performing as you drive it (even if the car is not officially supported, ECU Connect provides basic support for most cars using generic OBD2 CAN communication protocol available on nearly all vehicles manufactured from 2008 onwards). You can view and log any parameter the ECU records and even create unlimited personalised dashboards if you want to monitor specific groups of parameters. Save and send these logs direct from the app to your tuner. You can also record GPS coordinates in the log files, so you can see what was happening at any given point on your logging run (very useful on track days).

Syvecs Pro is a slick and unique app that makes use of the Syvecs bluetooth module, bringing a fresh new display that is packed full of amazing features:- 1) Dashboards - Syvecs Pro has multiple unique modern style designed dashes to choose from that are fully customisable by the user. - Each Dash has quick gauge swapping by holding a gauge and selecting a new input. The new gauge is added instantly and stored for future use 2) Data Logging that can be extracted and shared with tuners or to view in Syvecs Sview. The Data logging captures data from all set Frame and Slot content. Once shared and imported into SView, all data can be viewed as if it was exported from the ecu. 3) Performance Pack - This is awesome for anyone wanting to track the performance of their vehicle. Using a combination of data inputs and GPS, the user can track - Drag Tree reaction times - Standard Tree and Pro Tree - Top Speed - 0 - 60 mph / 0 - 96 kmh - 0 - 100 mph / 0 161 kmh - 1/4 Mile Speed - 1/4 Mile Time - Current Vehicle Speed - GPS Vehicle Speed 4) Warning System - Users have the ability to add Warnings for over 150 inputs received from the ECU. This allows anyone to protect their vehicles and receive instant warnings when something is not correct or is restricted e.g. Limp Mode as engine is cold. 5) Setup Wizard - We know how tedious setting up the frame content can be, so we have worked hard on coming up with a simple way to setup the inputs. The design allows the user to tap a cell and then select the gauge, the rest is taken care of and is stored. So setting up the app have been reduced from something that could take huge amounts of time to something that can be setup within a matter of minutes or select from a selection of preset data stream layouts. 6) Setup Tool - Stream Checker - When setting up the bluetooth module, we want you to be able to see when you have the best setup possible. Stream checker allows just this by giving the user the helpful data such as - packets of data per second - Number of valid packets of data - Number of invalid packets of data - Total packets received - Data ratio - And much more
