Hi all

Can someone possibly advise me the correct way of doing the above?

Should I do, for instance:
 Immo Off-->Calculate Checksum-->EGR Off-->Checksum-->DPF Off checksum and so on?

Or: 
EGR Off, DPF Off, IMMO Off, Lambda Off-->Checksum.

Thanks a lot guys.

what are you using to read/write ? do all your modifications, then write

I use K-Tag mate.

I wasn't sure if I need to do one "Off" at a time, correct checksum with WinOLS after/before each "off".

-------------------------------------------------------------------------------------------------------------------
Solved it.

I did all of the "OFFs" at once, then wrote it with K-TAG. Then did a fresh read with K-Tag, loaded into WinOLS, all checksums where spot on.

Thanks again

correct the checksums when finished modifications, ktag should take care of this
