wideband(5 wire) lambda wiring
Turbo Mini Forums

Do they have to be wired to a controller,or can they be wired to a voltmeter and a couple of heater wires like the 4wire narrowband

Metro turbo weekend driver,Mini turbo in the making again!

I believe they need the controller, or else everyone would be hooking them up to a £5 Aldi voltmeter rather than spending $275 on the proper AEM gauge........

You need a controller, such as the Innovate LC-1.

They are complex devices and work on a different principle to narrowbands. Hence, the voltmeter will not tell you anything.

Another reason I use megasquirt. You can buy one of these:

and conect it to the megasquirt for o2 measurment.

Detailed explanation here on how they work.



I'm fitting an LC-1 at the weekend. Using a DynoTune gauge from Turboitsonline until AlexF comes up with the Megasquirt.

I recently fitted an LC-1 to a car. I used a simple digital voltmeter display I bought off ebay to display my AFR's
The display is about 80x30x30mm, 5-15v power supply required, which in a car is easy.
Just configure it to display say10-20 AFR in the range 1-2v, and your sorted ( dec point is movable on the display )

Very cheap combo. Display was around £15, and LC-1 was a good price off Bill Shurvington..

speed didn't kill me, but taxation probably will

I've just found this which is quite interesting:

I havn't managed to go through the schematics yet or find a PCB diagram yet.

The old DIY WB.....

I follwed it for a while ( dont have much of a clue about electronics ) then found Tech Edge selling build yourself kits about 5 years ago.
So as they were selling complete kits of all the parts, i bought from them.
Some builds went better than others lol. Not their fault, totally mine.

each to their own of course, but when complete functional units really arent that expensive these days, I'll just purchase complete units now.

The LC-1 is good value at under £150

also the LC is tiny, basicly a lump in a cable!!

got the LC-1 too and a volt meter with movable decimal place wired as per stevieturbo. (also got it tied into megasquirt) great bit of kit.
