Haltech recently announced that they have updated new features on their single connector Elite ECUs: 550, 750 and 950 which now gives users the option of re-assigning unused injector and ignition outputs as well as integrated closed loop boost control, launch control and flat shift functionality among other features.
Whilst saying the above they haven’t forgotten to add something, that has been a long overdue need to their entire Elite series ECU’s which includes their Elite 1000, 1500, 2000 and 2500 ECU’s. That something you might be wondering is Water Injection.
However, in order to make use of these updates (ESP Firmware v2.37) you will first need to update to the latest version of the Haltech ESP software – v.2.45.0 which can be downloaded off their website or through the “ESP Online” portal if you’ve already got a previous version of ESP on your laptop.

What’s new in all Elite ECUs (Source: Haltech)
• Water Injection
You’ve been asking and Haltech engineers listened! All Elites now include an advanced Water Injection function offering broader control of water/meth systems.
With progressive and non-progressive options, you can instantly generate a pulsed output with multiple activation types as well as ignition corrections and fuel offset. You can also adjust Target AFR and/or cylinder ignition when activated.
An “Advanced Enable” feature offers options for various safety measures including conditional activation. For example you can monitor a generic sensor value (pressure transducer) and only trigger the water/methanol nozzle after the targeted pressure value is met.
A built-in override functions allows you to activate the injection system regardless of any activation condition or modes, most commonly used to test or “dry-fire” the nozzle(s) on racing applications.
What’s new in Elite 550, 750 and 950
• Integrated closed loop boost control.
Set target boost pressures and allow the ECU to actively maintain that value under varying conditions.
Also includes a long term trim option that populates and saves any corrections made when utilising the closed loop function.
• Single level of engine protection.
Prevent damage in the event of oil pressure loss or high coolant temperature readings.
• Launch Control.
Now integrated with correction tables for both fuel and ignition, giving you the tools to isolate engine mapping when activated (for example, transbrake or clutch switch is engaged.)
• Open Loop Flat Shift Control
One of the most talked-about features in the more expensive ECUs is now available across the whole single connect Elite range.
• Generic Timer
Set up Race Timer or any other event-driven timer.
What’s new in Elite 550
• Improved Idle Control.
Now includes Long Term Fuel Trim
• Unused Ignition/Injection pin reassignment
Elite 550 users will now be able to repurpose unused injector and ignition pins for function outputs.
• Flex Fuel Support
Now supports Flex Fuel and the fuel tuning options for both fixed and flexible ethanol blends.
• Onboard data logging
In addition to external logging, the Elite 550 can now log data internally with a 10 channel, 1MB, 50ms onboard logger.
• Single Stage Nitrous Control
Haltech’s entry level ECU now supports single stage of nitrous as well as the enablers and overrides available on the 750 and 950 models.
This function can be triggered by a remote switch wired to any of the available inputs on the ECU.
• Cam Control (single).
Variable Cam Control is now supported for engines with a single cam sensor, located on the variable cam.
