Need help with 93c66 for dash 2007 Altima please

**Wilberg93** · 18th October, 2019, 02:51 AM

I have posted the file just has been modified several times everytime I try to correct mileage it’s always higher than 500k miles
year is 2007 Nissan Altima 2.5 cylinder original miles where 144k there’s 2 93c66 eeproms. Top one gas mileage middle one I’m not sure what it contains. I have tried using jprog and carprog both legit softwares with no success. If someone has an original dump I can write And then correct. But until now all dumps I’ve tried none have worked all over 500k miles no matter what imput I put in it.

carprog is very inaccurate with dashboards in the U.S. It can work with some but not very good. and in many cases it will say mileage not found. This is normal do not trust what it says to you.
Also what carprog is saying could be in KM and not MILES make sure to keep that in mind.
Are you sure you where seeing 953,XXX and not 95,3XX.xx?
Try typing 235,000KM into carprog and see what happens.

I’m positive that I was seeing 953k on the cluster when connected to the car. Now I understand carprog isn’t so good but it is a simple eeprom I have tried every file posted on this forum that’s for Nissan with 93c66 keep in mind with out modifying the dump and still get over 500k miles it’s crazy I think I need an original clean dump.

Here is an original 2008 Altima bin 93c66 US car 224,760 miles. Has not been modified. Sorry i don't have an 07 at the moment. You can try if you like. If it works we can correct the miles.

PS, Can you post a pic of your cluster?

Alright everyone thanks for all the help I finally got it to work. My jprog interface isn’t working for eeprom and little did I know haha. Also carprog can’t calculate this Nissan algo for crap. So I ended up calling a friend and got it all fixed with dsp3. Thank you all once again.
