air/fuel mixture Wide band.Question
Hi does anyone know of a ready assembled buget unit, alternative to the lm1. This uses wide band Lambda Air/Fuel mixture moitoring. sounds like a great idea for setting up carbs spot on, but its quite expensive for personal/ home use. thanks lee
A friend is installing two of these in his Jaguar (v12):

He's not finished wiring yet though, so I don't know how it is working out.
I run 3 Innovate LC1 controllers and a DL-32 datalogger in my Jaguar (straight six, three carbs). You're
right about it being the way to go for tuning carbs. What with the Megajolted igniton and the almost
optimal carb tuning (need to try some different needles in the SU's), my car has never before run as
well as now.

Okay gonna open my mouth and see how ignorant I am...I am not sure what wideband is but I sure do understand affordable! I came across an unused K&N fuel ratio mixture meter on e-bay for real low investment and bought it. I researched it pricewise and found it was very affordable from K&N. It has a 10 LED scale running from lean to rich and a bit in-between. Haven't installed it yet since I am still building my Midget but just thought I'd let you all know about it

I'll bet it is a narrowband unit, which goes from about 12:1 to 17:1(air to gas ratio). Wideband sensors go from below 10:1 to above 25:1. Wideband lets you see exactly where the mixture is. Narrowband is usually used if the mixture is known to be close, as in a factory EFI setup. Then Narrowband is used to fine tune the mixture.
You can build your own narrowband for a few dollars plus an O2 sensor, which could even be used: http://www.scirocco.org/tech/misc/afgauge/af.html
Have fun.

If your after a cheap wideband unit and your not using the aux input of the megajolt than the best way to go forward would be to buy the NAW_OEM unit from 14point7.com. It uses a wideband sensor which you have to purchase seperately, amazon/ebay.
The NAW_OEM has two outputs, 0-5v and 0-1v. If you plumb the 0-5v into your megajolt and set the parameters through the software to read the right AFR at the right output voltage, hey presto a way to read off and datalog AFR.
