I'm using an mtxl I'm my 94 civic with s300.

I've removed r136 & r138 from the board as described in the s300 help file.

My main questions are:

Under the misc tab does eld need to be enabled? It's currently disabled.

On my display screen in s300 I have added a value for afr and for eld, neither display anything remotely close to my wideband gauge.

I'm stumped. Appreciate the help

 

ELD needs to be disabled. In the most current SManager you should only have to modify the voltage scale in the closed loop parameter. If it's still off, chances are your ground is noisy or your wideband may be defective.
Try simulating a constant voltage to the input (i.e. MAP power wire with a 1k resistor) and see if it gets the same reading as your voltmeter to ground. If not, probably a ground issue or possibly a bad ECU.
Or you could just use D14 or an analogue input on the S300 and avoid the headache altogether.

 

Wideband is grounded at tstat like the instructions said. The xenocron article I ran across said to ground at the ecu I think pin a24 (or a25).

I think I got that stuff figured out. How do I get smanager to display the value in afr vs a voltage?

Thanks for the help

 

Its listing lamda not voltage.
Right click on AF in the sensors window and click on propertys
Change from lamda to air fuel

Go into options, settings, units & select air fuel ratio & click ok.

 

Alright, That's what I was looking for. I'll do that here in a few minutes. Thank you.

 

Finally had a chance to check everything out...

Everything is set up the way mtber advised.



I can not change from voltage to afr/lambda scale in the sensor set up window...

 

lol
silly Hondata and its tired 1990's UI

 

I switched to d12 and it seems to be working.

 

In the sensor window, don't change the ELD settings, change the AF settings.

 

The afr settings in the sensor window were correct from the start.
