Sensor input- GM/ACdelco Flex Fuel Sensor & Wideband MTX-L

Hello Hondata,

Was wondering if there are any inputs on the 07-08 TL ECU/Flashpro that can be used for a GM flex fuel sensor (part numbers 12570260 or 12568450)? I would also like to input my wideband sensor (specifically MTX-L from Innovate) to the ECU.

Thanks

You can use an aftermarket wideband input if you go to the Cloased loop section of calibration and look at the Lambda section. You have 2 options there.

You cannot use a flex fuel sensor with it.

What plug and pin # on the ecu do I connect my AEM wideband output to ? I don't see the information on my flashpro
2007 TL TYPE-S auto transmission (getting boosted as we speak)
And could I use my output from wideband and connect to secondary o2 sensor to make it think that it is installed and reading for catalytic converter efficency ? for off road use only of course

B24 is ECT2 and E18 is ELD on a TL

Wow the wideband reading as way off of what the gauge reads ? is this normal ? I have the ground on G101, what can I do under boost my stock A/F sensors are about 1.2 points off of the wideband gauge, my gauge is a brand new AEM wideband failsafe

Draw a diagram of exactly how you have this wired and post it here.

just hooked my AEM Wideband to ECT2. Im not getting a reading on the hondata live screen. the AEM gauge continues to do its thing. I switched everything needed on the calibration. ECT2 enabled and selected ECT2 for my input. did not mess with voltage offset. also I am getting 5v from the wire from ecu. Any idea's? thanks

my ground is on g101, on the thermostat housing
my wideband output is on the ect2 pin
my wideband has always been off on the datalog
when i adjust the wideband voltage offset, it will only be accurate for a limited range.
example if i dial it in to read 14.7 when my gauge reads 14.7, if my gauge goes down to 11.5, my datalog will read 12 ish.
right now my offset is at -0.4v
