Breakdown Of What Has Changed In v1.1 Firmware

The latest firmware v1.1 for the 10in1 multi gauge we sell has arrived and stocks programed with the latest firmware are ready to ship. There has been one new display readout added and some changes to the way a couple of the warning functions work, and one of the readouts has had its display named changed, much to the joy of supercharger owners. We feel this firmware update makes the gauges even more complete and refined than the previous version and the changes to the warning functions have made them much more practical in the way that they work. The changes made in this latest firmware are listed in detail below.

Differential Pressure Readout Added

Differential pressure display and warning system have been implemented. While this readout won’t be for everyone, it’s a pretty cool little feature to have. For those who don’t already know, there is a 1:1 relationship between fuel pressure and manifold pressure on return style fuel systems, and it is especially important on boosted cars, if this relationship is broken, it indicates there is a problem with your fuel system, and the differential display is a great way of making sure the 1:1 relationship between fuel pressure and manifold pressure is working correctly and your fuel system is operating correctly.

Oil Pressure Warning System Updated

The oil pressure warning system has been updated, now it uses “RPM And Above” as a triggering metric for when the warning will sound. An example is you would now set oil pressure RPM to say 5000rpm, then set the oil pressure warning to a couple of PSI below what your normal oil pressure would be at 5000rpm. So for example your oil pressure is normally 50psi at 5000rpm, so you would set the warning to trigger at 47psi. What this means now is if at any time your oil pressure drops below 47psi between 5000rpm and redline, the oil pressure warning will trigger. Doing it this way means you can get a warning about oil pressure dropping in a much more practical way.

Fuel Pressure Warning System Updated

The fuel pressure warning has also been updated to now use manifold pressure as one of the triggering metrics for the warning. Similar to the change made to how the oil pressure warning was done, now with fuel pressure warning you need to set two parts. First is the “Manifold Pressure And Above” you want it to trigger, so on a boosted car, let’s set this to 15psi. The next part is the fuel pressure warning level itself, so let’s say your car runs 60psi fuel pressure at 15psi manifold pressure, you would set the fuel pressure warning at say 57psi, so what will happen now is if at any time when you are boosting at 15psi or above and your fuel pressure drops below 57psi, the warning will sound.

Manifold Pressure Readout Name Changed To Boost

The manifold pressure used to display as “Turbo” on the gauge, much to the dismay of some customers with superchargers. Being that Superchargers are somewhat common here in Australia and New Zealand, having the word Turbo for manifold pressure didn’t make a lot of sense, so it has now been changed to “Boost” to keep all walks of life happy.

How To Get Your Current Units Firmware Updated

For those that have already bought these gauges earlier in the year and are running the older firmware and would like it updated. We will have our hands on the programmer in the next couple of weeks, shoot us an email and you can arrange to send your unit back into us for the firmware to be updated. The only cost involved with this is covering the return shipping cost which is $10.50. Of course for those customers located in Brisbane you are more than welcome to drop in and we can update the firmware for you to save paying the return shipping cost.

These changes to the oil pressure and fuel pressure warning systems allow people to set them up in a much more practical way, before the warning systems were setup in such a way you really could only set warnings for each just below the values the car idles at, not the best way this could be done and is why we worked on improving it, but now as you can see from the examples above, they can now actually be setup in a very practical and useful way.

Any questions about the above, feel free to hit us up.
