when I start logging with evoscan the RPM goes to +/- 2500 for 1 min or so then drop back to regular idle for a couple seconds then back to 2500 rpm...
Is that normal?
Also all my logs are totally off
RPM looks like that that was a 2500-5000 rpm pull in 3rd

What am I doing wrong?
Help please

 

1, is your laptop on battery or car power? does not using car power solve it?

2, is the white plug removed? some people have difficulties logging with this plug connected.

3, you may have to remove and reinstall evoscan on your laptop.

4, baud rate and wideband set up correctly?

these are the things I worked with when something similar happened to me.

the reinstall was the finial answer, but I think that was because the reinstall reset the baud rate for me.

 

I have both cable connected I ll try wihtout the white one
thanks

 

works, and I had to change baud rate back to 15625
thanks nothere for your help!!!
