how to log AFR directly from ecu with evoscan

[SlowDSM_GSX2g]

i have a innovate lc-1 in my gsx, im now working with ceddy mods on ecuflash and logging with evoscan, but i dont know how to make evoscan logs my AFRs directly from evoscan.

i know that i need to run a cable from lc-1 output to the ecu and modify data settings on evoscan but im lost in there.


any help will be apreciated.

The LC1 has a wire for analog wideband (0-5V). This is usually ran to where the factory narrow band is, or the EGR temp sensor or something like that which isn't used anymore.

I can't help you on the Evo Scan stuff though. :/

thanks 4 the reply


im searching about it and found some people using the rear o2 input of the ecu, but dont know how to set it up.

 

[SlowDSM_GSX2g]

i already connected the yellow cable of the lc-1(analog output 1) to the rear o2 sensor pin, and program the output to work as a wide band( this output is programed as a narrow band by default)

log with evoscan and nothing happens on the afr there


if somebody has it working, please help me

the ecu uses narrowband to read the afr

 

[SlowDSM_GSX2g]

with the stock o2 sensor it reads as narrow band, but my car don't have any of stock o2 sensors (front or rear), only the wide band

a have seen people loging full AFRs maps with evoscan, thats what i want to do

 

[SlowDSM_GSX2g]

i found that if i running with my computer on the car i can log directly from the wide band trought the computer directly to evoscan, but i want to do "standalone logging" with my openport2.0 and this method dont work

you will have to wire one of the outputs from the innovative to the serial port on the computer that you are running the evoscan on. Then you just select which external wideband you are using in evoscan.

Btw you should have one of those outputs emulating the narrow band signal and run to the stock ecu as the front O2 sensor.

As per the manual its on page 12

6.2 Hooking up the LC-1 device to the computer
1. Connect the Serial OUT connection with the included 2.5mm stereo to DB-9 cable to a serial
port on your laptop.
2. Connect the terminator plug (2.5mm male plug with no cable) into the Serial IN connection of
the LC-1.

Thats the only way to do it as far as i know

i was under the impression that the OP2.0 cable could log innovative WB units directly using the Aux imput...

maybe this might help...

yeah I already use this method using the supplied serial cable on the lc-1 digital output and it works flawlessly with my laptop on the car, but i want to do standalone logging (insert a micro sd on the OP2.0 and let it hooked to record a trip without a computer)
thats why Im interested on do it throught the ecu

read trough the link i posted, about post 9 is where he tells you how to wire it to pin 8 on the OP2.0 and reconfigure it for logging...

yeah I read it , but I dont have a 2.5mm jack male to male cable to try this method, I will buy it

thanks

 

[SlowDSM_GSX2g]

I think the problem is on the configuration of the ecu or evoscan, my ecu is flashe w ceddy mods and it may have the rear o2 sensor disabled, this may be one reason so the ecu isn't loking at this pin


already ordered the male to male 2.5mm cable to try the direct conection but i waiting for it to arrive
