We are glad, that you are with us 
Today we are sharing you v3.4 update for UTCOMP-3 and UTCOMP-PRO.UTCOMP_v3-4_Setup-EN
Who can update and how to update?
Your satisfaction is our priority, so traditionaly, update is free for all
It will work with all UTCOMP-3 and UTCOMP-PRO modules. Update process is described in update manual (in software: menu help -> manuals). If you have troubles into switching to DFU (update mode) than you should clear device memory by pressing CTRL + ALT + SHIFT + R in software (all settings and statistics will be erased!) and update after that. You should save default settings to UTCOMP after update (CTRL + ALT + R)Changelog v3.4 for UTCOMP-3 and UTCOMP-PRO
Updated manuals are already available on REVELTRONICS' site. In this post I'd like to describe v3.4 changes so you can read about all changes in single place. First of all, I'll describe common changes for UTCOMP-3 and UTCOMP-PRO. Secondly, changes available only in UTCOMP-PRO. At the end, you will find info about some minor improvments.
Second channel for AFR. Added LAMBDA.
Added second channel for AFR readings, e.g. for V-type engines. In input/output configuration there is possibility to select AFR1/AFR2. Both wideband o2 sensors with controllers should be the same type. In GUI in user screens there is possibility to select AFR1/AFR2. In alert system there is single configuration. When alert occur - it is displayed AFR1 or AFR2. In data-logger are also AFR1/AFR2.
Furthermore, added possibility to switch from AFR to LAMBDA readings (LAMBDA1/LAMBDA2). LAMBDA value is displayed on the screen with double precision (X.XX). Configuration for lambda is available in settings -> advanced -> afr/lambda.
Fuel pressure readings
Added configuration for fuel pressure sensor (BAR/PSI) with GUI in user screens. There is extended measurement range for fuel pressure. For 0-99.9 value there is 0.1 resolution on the screen (for higher value there is 1.0 precision). In practise, you can connect 0-10 bar sensor for fuel pressure in petrol engine for 0-10.0 bar readings. You can also connect stock fuel pressure sensor on common-rail in diesel engine for 0-2000 BAR readings.
Oil warm-up information
Modified alert for oil temperature. Now there is possibility to set alert "above both thresholds". First threshold is for warm-up information (e.g. 60C). Second threshold is for high temperature alert.
Warm-up information will be not displayed if engine was started already with warm oil.
Inspection/Service for date
Added two new inspections for date, e.g. for annual service and insurance. Now there are available in total 8 inspections: 4 for mileage, 2 for motohours and 2 for date. You can set custom name for all inspections. Inspection reminder is displayed if left less than 15 days.
Configuration for third analog temperature sensor (NTC-3)
Added configuration for NTC-3 (analog temperature sensor). Settings and options are similar to NTC-1 and NTC-2.
Smart algorithm for outside temperature sensor
Added posibility to enable smart algorithm for outside temperature measurements:
- if read temperature is lower than current temperature -> update immadiately
- if read temperature is higher than current temperature -> average 20 measurements for speed greater than 25 km/h
Smart algorithm is disabled by default. You can activate in Settings -> Preferences.
Digital output control (DigOutUser) in UTCOMP-PRO
Added digital output control function. Digital output state depends on selected temperature or vehicle speed. It can be used e.g. for relay control switch.
This feature is described in details in separate tutorial:

HUD mode for OLED in UTCOMP-PRO
At the end small gadget feature
Added Head-Up Display (HUD) mode for OLED in UTCOMP-PRO. In this mode all data are displayed in mirror on the screen. You can use windshield or dedicated small piece of glass for reflection. There is HUD foil recommended to get better visibility. Visibility in day-light is.. not so good 
but in night... take a look:If you would like to use HUD as regular mode, I recommend to use dual display (one in HUD mode and second traditional in dashboard - you will need 2 modules) or use separate small piece of glass with HUD foil.
Other changes
- added USB reinit with ignition switch (more reliable USB transmision),
- fixed oil pressure icon for USER1 - USER4 region in user screen (4),
- changed fuel level alert - can be disabled for PB for LPG cars and changed minimum value to 10,
- changed RPM calibration (calibration value may be below 1.0)
- added possibility to prepare and save UTCOMP settings to external file in off-line mode (without connected module).
I can make photos under different conditions if you are interested.
