Performance Monitors
Discussion
Has anyone experience with Race Technologies AP-22 performance monitor? Good / bad or indifferent, any views would be welcome. If it does what it says, then it's excellent value.
Here's a link for those uninformed:

If you follow any links to RaceTech's site you will need to use Netscape, for some reason it does not like IE5.5 or IE6.

I bought one over a year ago. Shortly afterwards lent it to a friend and he's still using it!!! Really, he is!
It does everything it says it does.
Have a look at www.strangely.org/diary/200008/index.html
Its a friends site who also bought an AP-22 for his Seven. The link sometines throws a DNS error for some reason. Just hit refresh.

I've got an AP22 and it is very good, extremely simple to use and the results stack up with measurements from other sources. Having said that, my AP22 will soon be replaced by the new GPS data logger which does all the AP22 does and a lot more. Details on the race-technology web site.
Hi all,
This is my first post to Pistonheads! I've only seen the gassing station a few times but my mate Campbell (yes, *that* Campbell), told me about this thread which I have a particular interest in.
I bought an AP22 a couple of months ago and can confirm that it is an excellent product. I use it to check the performance of my Toyota Celica.
In fact, I've ended up going a lot further than the standard use of the AP22. I discovered it has the ability to output data in real-time instead of to its internal memory, so I'm been writing a computer program that displays and analyses that data while the car is being driven (for the use of the passenger, obviously!). I've made a web page about it which you can see here:

Cheers,
James.

Writing your own? What's wrong with the Race Tech DCAT software? Very powerful graphing capabilities, and includes a full-screen live display of lat/long acceleration.
The DCAT software is very good but its realtime capabilities are somewhat limited. My program plots the various measurements (lateral and longitudinal acceleration) and the derived ones (speed, distance, horse power) on a graph which is continually updated during the run.
Also, since it does not record to the internal memory of the AP22, it can record as many runs as you like, for as long as you like.
It does, of course, have the same inaccuracies as the AP22 over longer runs due to the cumulative errors - especially if you start going up or down a hill! This is why the new DL90 data logger is so good - it doesn't only rely on accelerometers to determine the speed, it can get an accurate reading from the GPS.
Incidentally, the main reason I started the program was because I saw something on TV which featured the Skyline GTR with its "G-Force meter". I've made a version of this with the AP22 but I can't find any more information about the onboard telemetry of the Skyline.
Anyone know anything about it?

Peter, how accurate was the meter at measuring the bhp compaired to the results on a roling road (I know they vairy on RR just wondered if its similar?)
It varies a lot with weather, tiny slopes, wind and so on but the numbers are reasonably consistent, and I got a recognisable torque curve out of it. I wouldn't really try to compare the results to rolling road values though. I use it to compare different runs to see whether the car is gaining or losing power, whether that gear was faster through the corner, how much grip I am finding so on.
Cheers Mel! Nah, I don't know why I knock about with that mad Cambelt character 
It was his fault I got interested in cars in the first place. We both were made redundant from where we worked a while ago. Campbell tried to blow up the building. Well...maybe not. I've just got a job as a software engineer working on motorsport ECUs so it's worked out alright
