How to...

[Schurmia]

I do have my Uego hooked into my egrt wire on my ecu and it is picked up and logged by MMCD but it's readings are off and it gets much worse as afr gets lower which is when it needs to be most accurate.

That's the scaling issue. It's a really easy fix with the source code. Unfortunately clint did a lot of work after the last source code he released. You could go back to the older version if you wanted to though.

So are you saying that version 1.8 won't work with the Uego but version 1.6 will? Sorry I am a little confused here.

^^^ditto.

[Schurmia]

Is there some reason nobody is able to get the source code from him for version 1.8?

It does look like version 1.6n should read the AEM Uego much better then 1.8...

Scaling for AFR input - Changed after 1.6N
Old 0-5V = 10.0 - 20.0 AFR
New 0-5V = 8.0 - 22.0 AFR

...Just switched over from 1.8g to 1.6n and looking thou previous logs and all air fuel ratios appear to be correct now.

Can you give me the link to 1.6 please

Here is the link for 1.6n.

THanks bud.

Obviously, there's a upside to switching to the 1.6n--being able to better read the UEGO.

What are the downsides of the 1.6n compared to the 1.8n?

Thanks,
T

Here is the update list of everything changed since 1.6n...

Well he never responded to me when I asked him if I could get the source code, and he doesn't appear to have ever responded to the other posts or PM's people sent asking about it. I'm not sure why he doesn't want to give it out.
