Oh, yeah, sorry, we're talking different things - to your eyes, sure. I have my doubts anything but the first, maybe second digit (ones, maybe tenths I mean) matters to your eyes!
I meant to the ecu, for tuning/EGO/logging!
Now. More Important stuff:
And after another pointless reply of mine he adds:1) on the 5v supply, the current draw should be a max of 200ma,
including the display, without the display it would be a max of
100ma. On the 12v supply it would be a max of about 2A, that is
for the sensor heater.
2) When I did the gauge I was just after ease of assembly and not
after space savings. I am going to redo the gauge in a month or so
so that the LED sits ontop/behind of the display IC.
3) The interface is digital, it is an SPI interface.
There is no official test of my wideband vs LC1 or others, but
based on my testing and development work the AFRs are typically
within 0.2 of them. Other users have experienced that JAW and
LC1 are outputting almost identical AFRs. I have yet to really
hear of anyone complaining about large discrepancies between JAW
and another wideband reader.

So I'll send him a link here and hopefully he brings some more talent and enthusiasm to our group.Hi,
The thing is that, if you look at the hardware everyone is using similar hardware and it all revolves around the microcontroller. I use an Atmega88, innovate uses the Atmega168, and Tech edge uses the Atmega168. I am sure others use a very similar micro, if not Atmega it will be zilog or PIC. The part that is really critical is the code for the micro, and often you can not really measure how good the code is based on price. I pretty much read and follow the datasheet for the bosch sensor,and design my system according the datasheet specs, if there is some secret that is not in the datasheet then I am at a disadvantage to the competition that knows.
The most advanced part of a wideband system is the sensor, Bosch did a good job with the sensor, so they pretty much should get most of the credit. I get a little kick from selling a DIY controller kit that is cheaper than the sensor itself.
I am very interested in EMS's, a long term project of mine is to build my own ECU.
I live in toronto Canada.
I do not mind you posting my email.
