hello there!

Can someone please check if the EGR OFF is correct for this ECU.
Is this a simple switch or are maps also modified?

How can I verify the checksum?

thanks in advance!

Hi!
This EGR OFF make by soft "EGR Remover", maps also modified.
KC OK in uploaded file.

thanks 2xded!

do you think this is sufficient for this ECU?
would a professional tuner do any better EGR off modification?
How did you find out what software modified the binfile? I 'string'ed the bin and didn't find any references :)

Hi!
I do not use MPPS, so I can not recommend it. It will be safe to do KTAG, IMHO.
See the pictures in the attachment, this will be useful for analyzing firmware changes.

so I found two maps - at 1C2FE2 & 1C3226 where they got 'flattened' to change the EGR valve operation. that correct?

if so, there are no DTC off - since the ECU should always be ok with the EGR valve / MAF changes - because of the modified map?

OK so I've flashed the ECU with this 'egr off' file - and I noticed no difference in operation of the EGR valve.
the duty cycle and command are changing as before - is that expected?

also, I read the newfly flashed ECU and the file I got is different from what I written. Is that normal?

maps you are looking for are at 1C4AE8 and 1C4B4E , its egr hystteresis map , just zero it

Thank you!
What do you think are the maps that the egr remover flattened at above addresses?
