hey guys, I'm trying to get my AEM Analog E85 wideband wired into the stock ecu (EVO9) to log AFR through OBD plug with EVOscan. can anyone helpout on this? i seem to be lost.


thanks

 

anyone?

 

Check the below thread out, if you have any questions, let me know.

Thanks for the reply Marios.


That was the thread that i have been following. mind that i have a 9 instead of a 8. but the only difference that i have found was the pin on the ecu.9=73 ; 8=75. so what i have done is wire the white 5V analog output wire into the ecu (73). i seem to get readings in Evoscan with the wire connected to the ECU. do i need to adjsut the evoscan formula? since im using the E85 analog gauge (reads 5.7 -11.9 AFRs) Thanks.

 

Yes you do have to change the formula. I'm going to use pin 64 for the ethanol gauge since I used 73 for my wideband. According to the EvoScan pin out pin 64 outputs 255 when 5v is applied so the formula would be something like x*0.3922. Maybe that will work for 73.

 

You need to adjust the equation until it becomes absolute, meaning that the value on the gauge and the reading/value in evoscan are the same.

so i am using the correct pin and have it wired correctly? the Evoscan formula is just wrong?.... so i should start with 0.3922*x as the formula in Evoscan? sorry for the noob questions, just completley new to logging/ ecuflash.

 

That pin is used for the rear o2 which most use to hook up their wideband but you should be fine. Yes, try using that formula and see what happens.

 

hey thanks alot.

 

Let me know how it works out. I plan on doing this next week.

 

Will do! thanks again man really appreciate someone helping me out!


also, lol a little off topic from this thread.... but would you also be able to help me out setting up the OMNI 4 bar to read/ log correctly in Evoscan?.. SORRy for my noobiness lol..


Im trying to get remote tuned sometime this summer, i just want to have everything ready to go.
