Installed yesterday night and took the car for a drive, it fixed 2 things.

 

1. I have now a Solid AFR correction all over the RPM. not bouncing left and right

 

2. I had an issue the car was targeting 15+:1 AFR during cruise. and I had to restart the car to target 14.7:1. now this issue is gone. and the car is always targeting 14.7:1

2 more fixes, I have found that the knocking on cruise disappeared completely and the throttle response becomes better.

I wonder how it will be after fine tuning the MAF scale.

Let us know how it goes.

yup this is where I bought it.

I will have to buy this https://www.iwireservices.com/product-page/maf-plug-08-14 as mine is very senstive to vibration and the correction goes to -25 which is the minimum in my ECU.

I though i would share the link if you would like to buy one.

Yeah I hear you. I will carefully check again each wire attached to the connector, 'play' with them while the car is running and will watch my fuel correction gauge. I will report for sure.

Have you ever solved this problem? did you find the part number of this plug?

Thats what i am talking about.

Orange line is the Wideband Serial Input.

Blue line is the rear O2 voltage input from the wideband.

I am using the rear o2 to log the wide band output. It works and i verfied that data with the serial usb out from the wideband device. Its the same however the data from the o2 is more noisy but it stays within the range and follows the output from the serial usb wideband.

Car is STI 2012 ans wide band is the Innovate MTX-L

Both outputs are logged from Btssm.
