FL2 odb2 speed & rpm

HeywoodFloyd · Apr 7, 2021

I know Land Rovers typically don't work with generic odb codes, so I'm suspecting the answer is "no".

But does anyone know if a 2007 FL2 will work with one of these generic odb2 speedometers off eBay? I've got a GPS Speedo in my 90, and I will happily install one in the FL2 if the answer is "no" but I thought I'd check first, as some of the odb2 ones have cool features and look nicer.

A F2 is ODB II compliant.

However, ODB II compliance in its regulatory form is about engine emissions - whether all ODB II compliant cars provide a vehicle speed output I don't know.

What ever its cheap enough to find out a ODB II dongle is dirt cheap and will bluetooth to your phone.

Interesting, that's a good idea thanks.

I have successfully used an elm327 and the torque pro app - not for speed right enough, but as said OBDII is a regulatory thing across all makes and models so it should do what you want

I only bloody works! My fancy speedo from China just arrived, plugged it in, set it to MPH, and boom, very responsive digital speedo. I got the extra special one that has 3 separate screens with all sorts of info, including the turbo pressure, all the temps, rpms, battery levels, basically anything the car knows about, is available on this little baby. You can switch it to some other information too, such as acceleration test, breaking test, and much more! It looks the part too, doesn't look cheap and has a few different options for mounting it.

I really only needed a digital speedometer, but all this other info in real-time is really cool too.

Looks cool. Does it take the speed from ODB or GPS data?

I'm not so sure. My car has a speedometer, so can't see why another is needed, and if it pulls the speed off the OBD2, it's going to show the same inaccuracy as the speedometer anyway.

The reason for me wanting one is unlikely to be if importance to most other people. But here goes: I have a 1987 90 with a terribly inaccurate speedometer, so I installed a digital gps speedometer. I have a 2018 Kuga, which my wife insists on having the digital speedometer shown on the computer screen. Therefore, in both of my other vehicles, I have become accustomed to digital numeric speedometers, and the reality is, they're much better suited to how my brain works than analogue needle based ones. I like to glance down and see a definitive number (regardless of accuracy) and maintain that exact speed, I don't like the concept of being at "roughly" the right speed. Once I went numeric, I can never go back.

So yeah, it's showing the same speed as the normal analogue speedometer, but in stead of knowing I'm doing around about what the car thinks is 30mph, I now know I'm doing what the car thinks is exactly 32mph for example.

Like I said, not for everyone. But perfect for me.

You can switch between depending on whether you want the accuracy of GPS or if you want to match the analogue speedometer and have more the responsiveness etc.

Must admit, I hate needles to - but I'm a big brave boy when I sit in the drivers seat

The maximum speed limit here is 60mph, it takes longer to get places - although there's hardly ever any traffic so that's debatable. However, when I'm traveling 50 miles or so on a straight road (with no traffic), I'm frequently looking up at the dashcam to see how far I can push the needle past 100kmh and stay legal.

That makes sense.

I used to switch our Kuga to that screen option when driving on those silly average speed roads. As you say, it makes slight deviations instantly noticeable.

Makes sense.

I'm pretty sure the FL2 Ipack LCD could be programmed (requires suitable equipment) to display current speed, as there is a genius on the forum at such things. He's put loads of useful additional information on the LCD screen, and I sure speed current speed in digital format wouldn't be too difficult.

Here's the modified Ipack showing time and battery voltage on the LCD.
There are other screens available too, like instantaneous MPG and stuff, but I'm sure adding current speed wouldn't be too hard.
