Air/Fuel meter development

[tony.mon]

I am fitting a pair of air fuel meters to my bike.
I wanted to set up a lambda sensor in each downpipe, with a means of switching between the two inputs to the display, so that you can choose which cylinder you wish to monitor.

However I decided to spend the extra and buy two complete sets so that I end up with two displays, showing both cylinders at the same time.
The displays I chose are simple digital numeric readouts, functional rather than attractive.

But I contacted another manufacturer, http://www.dtmpower.com (under the "electronics" tab) and although the display isn't waterproof he wants to make a waterproof one and trial it for bike use.

I don't need one, as I'm already sorted now (just waiting for mine to clear customs) but are any of you interested?

Looks good and at £150 ish cheap too .
I take it it's only for say one reading so if you wanted a reading from each cylinder one would need to buy two sets but still £300 for a full reading is still within reason .
I'll stick them on my Xmas list :/)
Thanks for the link tony

The mnfr is seeking someone to trial the waterproof one.
You'd need to weld on two lambda sensor mounts onto the downpipes, but it would only be £200 with two sensors and a display unit.

Or less than £150 if you were prepared to undo a sensor and switch it to the other pipe, or fit it after the system crossover to give an averaged reading instead of an accurate one for each cylinder.
You'd just put a blanking bolt in the unused one.

Come to think of it, if you fitted the sensor bungs to a spare system, you could rent it out so that people could set theirs up then pass it on.
Once the jetting is set correctly you could remove it, of course.

Very good idea . I was thinking of having it on the moriwaki headers as the initial bit of pipe from the engine is s/s . .
It's just a shame I ain't got the money right now .:-(

Off track I know, but those pipes are pure porn!!!!!!!

I should have kept the mori's and pinned them up on the wall. Titanium wall Mmmm...

What's with the end of the giant condom holding them up at the front. You been messing with larger animals Lloyd

A/F meters.....I'm waiting for the tech to advance a bit more or at least fall this side of the pond. Wireless lambda sensors and mobile phone apps. As for positioning of the sensor where is the best placement for them. As close to the exhaust port outlet as possible where it's about 1600 c or a little further down the pipe where it's cooled off slightly, maybe down to 1200 - 800 c or less. Basically is there and optimum operating temp for the sensors?

Have a look on Bosch website. But most of the advice is about positioning the sensor so that condensation can't settle in/on it.
The sensors have to be connected to switched live so that they are heated all of the time the engine is running- not much current draw so it shouldn't be a problem.

Some have to be calibrated regularly and some don't seem to need it.
