As a way of gauging interest in these units I've started this thread.
If you're thinking about a new AFR gauge and want the ability to connect it to your laptop for data logging/tuning purposes then this might be the group buy for you
In short, they're awsome units, I wouldn't have invested in them if I thought they were crap, or poorly made. They're about as good as it gets without spending horendous money.
You can either have yourself a 52mm gauge, in BLUE or RED, OR an LCD flat panel with cool light up white writing on a black background, high viz.
They come inbuilt with the ability to connect direct to the R5's (and any other) tachometer wire so you can log RPM vs. AFR straight to your laptop while displaying AFR on the gauge. The unit comes with a CD containing the logging software, or it can be downloaded from the efi-parts website.
They also have an EGT input inbuilt, so you can buy the optional EGT probe and have the one gauge displaying both AFR and EGT There is also an optional pressure sensor too that will let you log vacuum and boost. I should have these in a few weeks time. It can always be added at a later date.
For EFI car's they're especially cool, since you can connect the Zeitronix up to a throttle position sensor to log throttle position also. You can even couple upto the existing map sensor to record vacuum/boost without needing the seperate Zeitronix pressure sensor.
So in conclusion, in standard form you can view AFR on a choice of gauges and log both AFR vs. RPM straight to your laptop with the supplied serial lead. If you want, you can add the exhaust gas temperature probe so that the gauge can display EGT AND allow logging of it too, and finally you can add a pressure sensor to add a vacuum/boost trace to your data logs. They come with everything you need, including the wideband probe, CD, cables, gauge and mounting screws, etc.
If I can make an order for 5 units I can send them out at 260.00 + 5.00 p&p (special delivery, usually next day). The only other UK stockist is presently selling them at 329.00, to give you an idea of the discount over UK RRP! I have 9 or 10 of them in stock presently, so delivery will be fast, but in order to replace them at a good discount from Zeitronix I need to make an order for atleast 5. If I don't muster 5 orders then they can be had at a singular price of 270.00 + p&p.
EGT probes are a further £58 should you want one of those.
