Well can you?

A blank post?

Tha was far too quick David

Shift light?

Port and starboard lights incase it rains alot?

Shift lights? and yes, far too quick David!

Yeah, but now it doesnt make sense

Home made shift lights by any chance?

is it the lights that do kitts voice in night rider ?

Blimey 3 of us posted at the same time!!!

Make that 5!!!!

NOPE not even close.

I was just going to write that Donut, but thought naaaa, by the time I wrote it, someone else would have!!

Fuel gauge?

disco lights ?

Something to do with Fuel Injection?

Scare-o-meter. Measures your passengers level of fear as you take another roundabout sideways at 70mph...

So its not a home made flasher from the bonnet of Kit from NightRider then?

Fuel / Air ratio lights

G force meter?

Now wasn't that fun....

That was fun

The idea is that it will connect directly to the wide band lambda sensor and give real time graphical representation of how close the engine is to stoik value.
It works on the bench so now it's time to install it in the dash.

I must say that was the fastest growing thread i have ever seen!!

Hi

Looks cool, you got a parts list and circuit boards layout drawing ?

A 20 LED, or for that matter any, air fuel ratio gauge running from a narrow band sensor will be as good as useless as a tuning aid.
The reason is that a narrow band sessor will tell you if your mixtue is rich, lean or at 14.7:1 What it will not do is give you reliable indications of how weak or lean it is. The slope of the graph is just too steep and not linear enough. Plus the readings at high revs and low MAP will be useless.
An indicator consisting of 3 LEDs would give you as much information as one with 20.
ie. Lean - OK - Rich.
With a wide band sensor you must use a controller such as the innovate LC-1 to drive the sensor . This you can calibrate to give you whatever output you desire. eg. 0 - 5 volts = lambda of 0.5 - 1.5.
This is the default output 2 setting of the Innovate controller.
I will re-calibrate the output to give me 0 - 5 volts but at a changed lambda value of 0.7 - 1.3. The reason for this is that it is unlikely that you would be running in the very weak or very lean areas that often. Even when you are, that information is not particularly relevent. eg. on overrun. It is therefore more usefull to expand the readings in the area which you will be running most of the time.
Your gauge will help you get your carbs near for the purposes of idle settings, emissions settings and to a limited extent cruise mixture but that will be its limit.
You will not be able to tune acceleration enrichment for example as it will not be accurate enough to tell you how rich you are.

Who said shift lights??

You see in the picture 5 leds...

the scale will be as follows:

the outer ones are Yellow, 4Krpm.
Then comes Green 6Krpm..

then the middle one will be orange 8Krpm..

then when hitting 10K all of them will start flashing, sow you now when it flashes you need to upshift....

its the same as in the F1.. they have it on their steering wheel..

it senses its rpm from the negative side of the coil.

Rescued attachment shiftlights.JPG

and you have drawings for that shift light set up!!

I fancy making that!!

mine only needs a coil.

i used this:

- Pic16F819
- 5 bright leds in their colors
- 1 4N25 (opto coupler)
- 2 10K res
- 1 zener 5volts
- 1 normal diode
- 1 218ohms res
- 1 7805
- 1 1uF cap
- 2 small caps 0,05uf

the pic does the hardwork since they are free and this model is taken because of the built in OSC.

its no really developped but it works if the zener is changed for one with 24volts.
the caps could be eliminated altough teh 218res should maybe be higher
