I've had some questions about the gauges being slow on fitfreak.net and I've been testing why that is with a scantool obdlink bluetooth and torque (paid).
I noticed that the data incoming seems to have no lag time whatsoever but the updates and drawing of the gauges--especially the dials--seem to be adding a small amount of lag.
Have you put in any filtering of updates in the dials to limit the maximum updates per second?
Would you be interested in any help in making the gauges faster?
Thanks,
Kevin

I second this demand and ask if it depends on the phone or not ?
I have a HTC Hero, which has a poor processor and a little RAM.

I don't know if it's right to "demand" anything. I just want to help make the app better and was hoping to get some answers without my having to reverse engineer it.

It seems that a value used for drawing of gauges' needles is the avarage of incoming data. Just check youtube for videos where people test rpm. You may note that when you rev the engine & rpm rapidly increases the digital rpm indication can be much greater then the one at the gauge. It means that actual data has less lag. But drawing is based on avarage of few previous measurements. It makes the needle movement smooth but lagged.
I'll test this on my Infiniti Fx later. I just ordered OBDLink MX WIFI. And I have CarPC based on x64 architecure with FTDI OBDII/CAN cable. This shows no lag at all. So I will test how can WIFI connection and a good adapter perform on Android/iOS/Win64. But for shure there is an avarage calculation in Torque for drawing.
I'd like to ask Ian to make this avarege adjustable by user. So that user can set no avarage and drawing will be done as per current value.

Please check out this video

FF to about 1:08 when driver rev the engine. Put to pause. Then frame by frame check that in some case when engine spins up digital rev shows about 3800 rpm while gauge needle is still at around 2400 rpm.

Screenshots of that video
Rpm is 3808. Gauge at 2400.
Throttle is released already. Compare value in digits & gauge.
Same for others
