Re: WB O2 output
its probably worth plugging into the serial port of the MTX-L and checking!
No matter what the question is, the answer is always more horsepower!

it will tell you what the o-5v settings are set to.

Re: WB O2 output
Ok thanks mate. Looks like I'll have to chase up a usb to serial adaptor. Do you know of any good ones?

Look for one with an FTDI brand chipset.

Re: WB O2 output
With the LC-1 you can change the 0-5 volt to whatever you want. Not sure about MTX-L as I've never had one but instructions look to use same LM Programmer?
For TunerPro conversion on Innovate default AFR of 0V = 7.35 AFR and 5V = 22.39 AFR
AFR of 7.35 to 22.39 is a difference of 15.04 divided by 256 = 0.05875
Conversion for this would be:
(X * 0.05875) + 7.350000
Heads up for you guys and FTDI Chips, drivers and cables!!! We found some issues either with chips or updated drivers or? FTDI has been sent chips from same batch that some will and some will not work with new drivers but do work with old drivers. Not sure yet but some info here:

Set "VE Learn Params - WideBand 0v AFR" and "VE Learn Params - WideBand 5v AFR" to suit the wideband - so 0V to 10AFR and 5V to 20AFR with a 14point7 kit if that is what the output is set for (there should be instructions with the kit that specify the output).
Just watch out for that eaglemark, when people are running 12p.

Re: WB O2 output
I've got some catching up to do with you guys across the pond...
Re: WB O2 output
Ok - I have connected to the MTX-L with the serial cable and the settings in LM programmer are correct. The 0-5 volt readings are the same as set in TP. (7.30 & 22.40) When using the logworks program the readings are the same as the MTX-L gauge.vc81 wrote:I have exactly the same problem but with a mtx-L. The wideband 0V & 5V scalars are set on 7.30 & 22.4 which I believe to be correct for the mtl=l. Any ideas why the mtx=l gauge readout is different to the TP dash readout?benk wrote:have an issue with my WB O2 sensor doesn't seem to be reading correctly in Tunerpro.
I have a 14point7 kit installed and the readout is around 1 unit out to what Tunerpro is reading. Wanted to check output range on the Wideband and input in TP to make sure that they are the same. I can remember reading something about the settings a while ago but can't seem to find the post. Can find what the settings are on the wideband controler but not sure where to find them in TP
Any ideas why the wideband dash gauge in tunerpro reads differently??? It's about .6-.8 leaner than the MTX-L and logworks readings.

Re: WB O2 output
Which code base (12p?) and how did you configure tunerpro/the ecu for the mtx-l?
