Looking at the data (and knowing the spec of your car), I'm surprised to see the lengthy dips in Long G when you change up the box... you still using the clutch for up-shifts ?

You never will I'm afraid... the best way to determine the start of your run is to look where the long G's first go over, say, 0.3 long G. Though looking at your data you need to mount the logger more horizontal, as at rest you are showing around 0.33g braking! I believe this can be tuned with an of...

This is how to connect up a remote start/stop switch... though it wanders off and talks about using RT's four wire illuminated push button... m Basically use a simple momentary switch between "Start Logging" and "Ground" on the back of the DL1. I've been using m for quite a few y...

Let hope he doesn't get run over whilst on holiday!

I split a grommet then use lots of silicon sealer

yes, drop me a mail at llandow_data@emcos.co.uk and I'll send you some back.

+ or - 2% is not really an issue, you will probably have to filter the signal anyway to remove vehicle vibrations. Make sure the unit is mounted as level as possible. I tend to use the auto zero feature when loading runs which helps show the relative change in G.

A lot of ECU's turn off injectors on the overrun to save fuel... hence you will loose the rpm signal. The same can happen for signal sent to the coil(s).

Motec do a dual channel one for around £65.

lots of other useful sensors on their as well

register (for free) and then download the data sheet to make sure you get the one for ABS sensors.

DashWare combines data in CSV format and video together. It can't compare runs against each other, unless you make viedoes of each lap and then perform a frame by frame analysis...

No, but you might be able to output CSV files from RT data and compare with excel or something similar

What about other channels eg from ECU, do they "suffer" from the same fate when no more samples are received by the DL1, they will also continue to report their last reported value ? Maybe, a simple method to reset value to 0 after a suitable configurable timeout value has expired for that...

Could be lots of things... worth checking your RS232 wiring with a brake out box and also the configuration of the RS232 on your device (baud rate, data bits, parity, stop bits). Double check your DL2 configuration settings as well.

Received thanks Had a play over the weekend and think I'm ready now

Has any kind soul got a .RUN file for Spa (full GP circuit ?) email to me at toby_harris_1999 @ yahoo.com ?

I'm racing there in a few weeks time and would like to prepare myself and the tools before hand

Cheers
