Title: gti check sum problems stumped! Post by: ktm733 on November 01, 2014, 12:15:12 PM 06A906032HS gti 1.8t me7.5
Today i was tuning a gti that had a code for checksums but the car still started. so i said i could clear that up with ecufix software. So his file had 8 checksum errors I fixed them and then flashed car. Car didn't start? So i flashed old file back onto the car and it started. He still gets check engine code which makes him fail emissions. Could you guys take a look please. Thanks the first file is the orginal file. second is check sum updated one. Title: Re: gti check sum problems stumped! Post by: k0mpresd on November 01, 2014, 12:49:40 PM problem is pretty clear. did you even look at the file?
Title: Re: gti check sum problems stumped! Post by: ktm733 on November 01, 2014, 01:28:39 PM I don't see what I am looking for in the file?
Title: Re: gti check sum problems stumped! Post by: k0mpresd on November 01, 2014, 01:54:50 PM well its not stock. thats step 1.
Title: Re: gti check sum problems stumped! Post by: ktm733 on November 01, 2014, 02:03:48 PM So it's tuned by ex. apr or giac, so I need to upload a original bin same sw everyting. Great now my tuning skills will come into play against an apr tune. he said they ran a test version on the car and reverted back to stock, but why would apr set a dtc for checksums and fail emissions because of this?
Title: Re: gti check sum problems stumped! Post by: k0mpresd on November 01, 2014, 02:46:25 PM no trial verison reverts back to stock. it reverts back to "stock". their code is still present.
Title: Re: gti check sum problems stumped! Post by: ktm733 on November 01, 2014, 05:10:17 PM Oh awesome thank you so much. How do you know this by just looking at it though?
Title: Re: gti check sum problems stumped! Post by: turboat on November 02, 2014, 02:49:42 AM Not looked at your file, but usually:
Having a tunerid set in the file is a clue, loading definitions for the file and the maps being all wrong is another clue (when you graph them they don't look like maps, they look like crazy lines - because the tuner has moved the maps and you're just seeing random data) and when you look at enough bins, you know what they should look like. Title: Re: gti check sum problems stumped! Post by: ktm733 on November 02, 2014, 10:31:12 AM Weird the only map i saw that was weird was ldrxn. Also where did you see the tuner id? Just for future cases when this happens.
Title: Re: gti check sum problems stumped! Post by: ktm733 on November 02, 2014, 10:33:24 AM Also was wondering can I grab a bin that is same sw and id number and transfer it onto the bin? Or does that carry over the eprom from the file I'm uploading that's not the original bin?

Post by: turboat on November 04, 2014, 02:22:28 AM Don't quite understand the question. Eeprom = .bin file Eeeprom = bin file, flash = different bin file. Dont confuse the two. To put it back to totally stock you need to write flash and eeprom with stock bins. Title: Re: gti check sum problems stumped! Post by: ktm733 on November 04, 2014, 04:53:39 PM Question.. flashing a bin (bin from the original bin section on this site) be fine?
