what is latest SGII™ version?
 

Q: what is the latest software version, 3.17 or 4.0, for SGII™?

...anybody know?

...I've seen both mentioned and am wondering if I need to look into getting an update?

4.01. I'm not sure what the latest changes are. The latest hardware has a faster update rate but I doubt a software upgrade can change that.

...Thanks! Just got this from Linear-Logic for those who are interested:

"Thank you for your enquiry. Yes, there is a new software that was released a couple months ago (version 4.05). There are benefits to upgrading to our new software. The following additions that have been made to the ScanGaugeII:

- The ScanGaugeII now has a performance feature that allows you to record your vehicle's short trips and lets you go back and view 0-60 times, stopping times and distance.
- The engineers have designed a new menu systems that is easy to navigate and also a new user manual which is much easier to understand than the original
- The new software has corrected some minor bugs that were in the previous software, such as finding certain trouble codes (on rare occasion, some vehicles would display a P0000 code reading on the ScanGaugeII).
- There is now more enhanced X-Gauge capability
- Changes were made to units and now the ScanGaugeII can display KPL (kilometers per liter) and inches of mercury for the manifold reading.
- Currencies were added and now the ScanGaugeII can display Pounds, Euros, Yen, US dollars, and Yuan
- A feature was added that allows you to calibrated the ScanGaugeII in order to figure out boost [(if you vehicles reports MAP (Manifold Absolute Pressure)] and horsepower.
- A minor protocol (CAN long ID) glitch was fixed
- The compatibility issue between the SG2 and Mercedes Benz vehicles was resolved."

Ooooh! That's, like, 0.04 better! Dude! :p

Thanks for the follow up.

...yeah, but they *still* have the problem with the 2011 Cruze randomly affecting the car's "fault" displays.

...was hoping it was fixed, but alas it's not (yet).

So, is this a firmware update? Can it be "flashed" onto a ~2-3 year old unit?

...the above response from Linear-Logic was their reply to my inquiry, about updating my SGII with version 3.17 firmware, which was purchased from EcoModder back in Dec 2009, making it almost 2 years old by now.

So, you were able to update this on your gauge? If so, did they send you the firmware update, and what is the procedure to do this?

Edit:

Here's the info from CleanMPG:

Bottom line is it costs $25 and you have to mail it to them to have it done.
