Wide band controler

[ragepower]

Hi

There is some DIY project and PCB to do a wide band controller to use with a MS3? I don't see any.

I know that it is very complex and most of the times it use a microprocessor, maybe there is someone who do this controller without a microprocessor.

The best to do this the best way was buy a gauge wideband (AEM maybe) and use the linear output that it have but it is a little expensive.

Anyone have the PCB and schematic of a wide band controller?

Go to 14point7.com they have some diy type controller modules that might be what your looking for.

I'd still advise using a TechEdge 2A0 instead.

I forgot that. But i wanna find an europe supplier of controller because the customs service apply high taxes (about 30%).

But you have some experience with the 14point7.com controllers? These controllers do that job right?

Techedge now has an 'OEM' model. It has a small footprint, supports the latest LSU 4.9 sensor, and can fit into the megasquirt case. I highly recommend it if you are trying to keep all the goodies in one box.

14point7 also has an OEM model which is even smaller: http://14point7.com/SLC-OEM.php

Jean,
I like that footprint too! too bad it's a LSU 4.2 not a LSU 4.9. but for $100 USD (sensor and controller) you really cant beat either one.

Does that really make a difference?

I've been working on setting one of these up. Been in contact with the owner of the site, and got some more details on this. It uses an Amtel ATMEGA8 microcontroller. Parts to make one are about 15 dollars, and it uses an LSU 4.2. Add a 10 dollar AVR programmer, and you are set. Needs a bit of fine SMD soldering, but otherwise it isn't too bad.

AFR (gas)= 10+(vout*2)

Lambda = (10+(vout*2))/14.7

Why go through the trouble of making another analogue output wideband controller? There are litterally half a dozen to choose from already for reasonable cost.

If some one is going to go through the trouble of making one, why not make a CAN enabled unit that would interface with MS2/MS3?

You more or less have that if you use an IOx with the optional SLC-OEM carrier board (up to 8 controllers in the same box). Or you can also connect up to 8 LC-1s to a base IOx but that's not a single box.

You could take his open source project and add the code needed to run whatever communication protocol you wanted, including one specifically tailored for the MS can. If you were clever, you migtht even be able to do it without any other "carrier board" hardware.

There is not much need to be clever for that because you simply need to have a CAN transceiver (and a CPU that has a CAN bus) but the advantage of the carrier board is that you can have multiple WBO2 controllers with a single interface.

Jean, I think that option with your IoX is great, but do feel there is a market for single (or dual) O2 controller that communicates via CAN for individuals who may not have a need for additional I/o, but don't like the analog conversion and associated calibration.

Yeah I meant you could use the CAN with the MS and all 8 devices on the same bus. It would probably require some help from the MS devs and Phil, but since the IOx got integrated so nicely, I don't see why it couldnt happen for other devices. Especially DIY open source ones.

I agree that it could be interesting and that for a lot of people the IOx is overkill especially if the only need is to get the digital AFR data.

There is no need to do anything to support this. Both MS2/Extra and MS3 can get their AFR data from the CAN bus so anyone can develop this if they can implement the MS CAN protocol. And TS integration wouldn't be needed unless there are some parameters that need to be set (and even then TS support is not mandatory).

However, I don't see why it would be different if it was open source or not.

Just a quick question- Is the PWC officially dead?? (anyone know??)

Its been many years now since it was even mentioned.

As I understood it 18 months ago, there were plans to create it, but mainly as a research tool and not necessarily retail.

Assuming my recollection is correct, I wouldn't be waiting for it.

Hello,

I'm currently working on a project where I use the Bosch CJ125 IC to implement the LSU 4.x lambda controller. It will be microcontroller operated for diagnostic and configuration reasons.

If you are interested in the CJ125, there's a very good source in German:

I tried to make it but it didn't work very well, it kept showing lean. What fuse bits did you set for the atmega8? Is there something else I need to know to make it work? Thank you.
