Considering to buy Ultragauge to keep an eye on AFR, Boost, IAT and coolant temp. Problem is, they don't provide any information about if the device will show them or not. They say it may be supported or may be not.
When I check it on their compatibility page and picked Polo GTI as they're cousins with Cupras since no option was present for Seat, I see that all information I want 'would' be shown, but it is still unclear for me, even some say that if OBDII supports it (to be shown) Ultragauge will show it. In that case, I use Torque app and see what I want, so it'd be quite good pick for me as a multifunction gauge. (it would be good if AFR would have been shown in ratio, not lambda though. I want that 14,7
)
So, anyone using ultragauge here?
If you have any other gauges like ultragauge and think they're better, feel free to suggest it
