Default 1.9TDI ALH, running dynamic EGR, when car is on MAP, not MAF?


I was wondering is it possible to have dynamic EGR, when car is based on MAP smoke limiter, not MAF?
I don't know even is it possible to be on MAP smoke limiter and have working EGR?

Thanks for your time!

yes it is possible there are several vag EDC15 applications using speed density smoke maps but still using EGR. I would suggest studying them to learn how to do it.

but you will still need the maf sensor to control egr, there is no such thing as "mafless egr"
HP is for show, TQ is for go.

Thank you very much, KERMA!
I did removed MAF from the car and there is a block plate instead of MAF, so I can't control EGR right now.
