[gomarota]

Hi, i think i found two EGR maps at 56168 and 76168


i put all to max value (8500) like in photo, its all right? or i have to search some hysteresis or switch?

That is EGR according to MAF map.
EGR off is a switch byte in these ecus

I find if you turn off the EGR function using the 8bit switch, it also stops MAF function, so you'll need to be running MAP based smoke limiter and you'll need to disconnect the VAC pipe from the EGR or it holds EGR fully open. After this, it works just great, successfully done on several EDC15P+

This is my findings....

@gomarota hey that single switch is to configure map smoke control or MAF smoke control, don't touch that sir.

it's very simple in ec15. Just fill the map with the higher value you seen in EGR via MAF map and it's done.

After that you can unplug egr and the car wil work normal with an error, if you want just disable correct EGR DTC error to hide it from diagnostics.

Hope it helps sir..

You just need to touch hysteresis in edc16.

Have a fun.
