Polo 1.4 16V AFH Marelli IAW.1AV

Hello everybody,

I am trying to tune a mates Polo with a 030906030D ecu. I haven't desoldered the 27c512 plcc32, because the car isn't near me.
I managed to find a 030906030D file and i had a look.

My questions are:
When i change a few values, do i have to correct the checksum, so i wont have any starting issues?
What about immo, is it going to have different immo file in it?

[AlexG40]

Please guys,

Its urgent if anyone knows anything i would be grateful, if he could share his knowledge

[kospoz]

yes my friend you must correct the checksum
If you want to tune there is no reason to play with immo values

Thank you for your reply,

In my case i dont have access to read the ori, because the car is not close to me. I managed to find a ori bin file from a forum.
I have noticed that in the ori eprom there is a sticker with the checksum stamped on it (2DE1) so the file i found had the same checksum.
Will it be any problem?

no problem (if the rest following numbers in ecu is the same)

[AlexG40]

Any ideas guys.

is there somebody that has tuned this ecu before?
