Hi

The Speed, Acceleration, Lateral G, Longitude and Latitude data come from the six axis gyroscope embedded in the Android device that the app runs on.

Anyone had success running this on an android headunit?
Plugged it in and seems to work, but is very laggy. Menus and moving items round is fine, but signal response takes a couple seconds to update (only tested with throttle pos so far though) - guessing that's the weak processor in the headunit though?

Headunit has normal USB A ports, so no need for an OTG cable if anyone was wondering.

Wow!

Nice.

I had a Samsung S5 when I wrote RS-RV8.

I built an engine simulator around a Lucas 14CUX ECU that a mate posted to me from New York.

I never tested it on an ECU running in a car.

So the lag, performance, behaviour etc I can't comment on.

I wonder if that head unit would fit in a Cerbera?

Tis just a single din with a flippy screen, will fit any single din slot smile

Not the exact model, but:

I take it you can't have the screen out and change gear at the same time with a chim? I thought about fitting one a while ago but guessed I would need a bag of plasters for my knuckles hehe

No issues or contact whatsoever, the only thing it hinders is adjustment of heater controls and vision of the clock, but there’s a clock on the screen and you can reach around to adjust the dials.

I like this sort of thing but if you get your car working properly these things can become redundant fairly quickly.
I remember years ago when this first came out thinking how brilliant.
I started having intermittent problems with my CUX and at that time I had ecumate which gives you a lot of this information but on a small screen etc. You will find once you have it up and running properly you will hardly reference this screen other than a quick check every now and then. After awhile all this info becomes irrelevant.
I concluded that having Rovergauge was all you really needed and only when you need it.
AFR Gauges another one, it’s very easy to spent your days looking at that worrying lol.
You can not get enough info so I really like this screen set up but experience will show when the car runs for months and years properly you will barely use it so then the Rovergauge cable and a lap top will do.
I understand people with cars on the limit need as much diagnostics as they can get so turbo or very highly tuned cars Afr meters etc a damn good thing. I remember thinking I could have one when installing a new ecu system. Truth be told the AFR readings are so consistent on a modern system on a mildly tuned car It’s not really necessary to have a gauge confirming this.
The old adage still stands, you have to tune by ear and feel so a gauge is good to tell less well tuned ears it’s about to go bang.

What I’m trying to say is you can end up ruining the driving experience by constantly considering stuff you really don’t need to think about if you just keep the car in tip top shape.
Maintenance will help more than this will.

Except it's a TVR, so even after you get it running right, things can break at any time. Just caught a lambda sensor that conked out, despite being fine a couple days ago. Would've been none the wiser if i didn't have RS-RV8 on my dash, and the battery gauge as well as digital speedo are always nice to have.

However, @aide, is there any chance the refresh rate could be increased? Though it was lag / delay before, but think it's actually just that it doesn't update frequently enough, which is especially noticeable for the RPM guage.

Really!
Well yes I suppose so but that’s got to be an age related issue as most the components are tried and trusted from major manufacturers. A Lambda can go down anytime and if a car has a very poor maintenance history fair enough but that’s not Tvr fault.

I’d be more inclined to think half the problems these days are related to poor bodges and dodgy diy repairs as TVR have had nothing to do with these cars for a long time.

Alun, I'd agree - dodgy diy repairs are common.

That, and the appalling quality of some of the replacement parts - often in branded/OEM packaging.

It’s why specialists who supply parts to cars they repair are often the best ones to buy from.
Imagine what a game repairing cars must be like now you have a market flooded with iffy parts. I’ve watched one of the better dealers back in the day researching these parts and it’s hard to keep track of the quality for even these companies who have people working full time sourcing the stuff and sadly now it’s very difficult to get quality at all.
It’s a bad situation for anyone on older tech electronics.

I’ve just entered the weird world of East German motor cycles ( for a laugh) and even there you buy from one or two companies via Germany, a few respected chaps over here but basically it’s all crap on the internet and don’t buy it is the advice.
I dare not even buy a condenser for a fiver for fear it will fail a few hundred mile down the road.
Infact some of the stuff advertised are actually incorrect and need fettling, i can’t be bothered with rubbish like this in our day and age, it’s a disgrace as it’s generic selling of basic but vital components. Rant over rofl

The modern world,, a huge choice of complete crap mostly thumbup

hi Aide

just downloaded the Rover Gauge app. on my amazon tablet. Looks great, can you advise when you switch on the logging, how do you access the log files, where are they stored ?

many thanks
