How accurate are the EGT readings in Evoscan? Has anyone compared the factory EGT sensor to an aftermarket unit or is this another narrowband/wideband discussion sorry if it is. I am asking because I am getting ready to do a custom turbo intall on my car and am looking for places to save money. If the factory unit is accurate I don't need another one just so it reads out on my a piller.

 

There is not a factory EGT reading. You are referring to the EGR temp which has no value when tuning.

 

ahh, that's right. I must have changed that in my head from the last time I looked at my logs. That's the true power of hope I guess. mo money mo money, wish I could afford an M3 Thanks for the help man.
