AFR Gauge Showing Different Reading (Innovate MTX-L)

Post by rockyboist » Thu Mar 23, 2017 11:53 pm

I did some pass and took some logs to tune my VE (thanks to Autotune) but when comparing my logs to the actual value I seen the Innovate MTX-L the gauge shows very rich around 10 AFR, leanest I've seen was 10.7 and as rich as 10.2. But the logs from the graph show differently and that I am just within the LAmbda target 11ish AFR if I convert. So which one is correct? Is the gauge itself very slow to pick up these changes from the sensor? Attached my log.

If using an external wideband you need to make sure the Innovate gauge shows the same as the reading in the EMU software
Adjust the numbers in the EMU software until they do

Yes thats correct. Found what the issue is and it is the voltage mapping on external controller, problem is the EMU voltage mapping doesnt let me put the minimum and maximum values Innovate wants, so need to connect to Innovate and change the mapping there.

I've had this issue with most ECU's and the numbers they suggest never match up perfectly I always use the Innovate gauge reading as the correct number.
I mostly use the built in EMU wideband controller and the numbers match perfectly when run next to an Innovate setup

Connect the mtx with your Laptop and Run LM Programmer.
Set update the correct Afr 0V = 7,35 // 5V = 22,4

Put the Same numbers in Emu software.

Works perfect for myself

Yeah thats the plan. Just looking for a serial cable adapter. Thanks.
