s300 v2 problem datalogging!!

[jgracing]

I am having a problem datalogging with my s300 v2. It worked perfectly fine for about a year and a half but now its not working right. So it works if i do 3 gear pulls 2nd gear pulls normal driving things like that, but if i try datalog a 1/4 pass it completely stops working when i launch or ill look back at the datalog all displays are one straight line all the way through the run even when im off the gas till i stop datalogging. I dont know what would be the cause of this.

Are you using on-board datalogging or using a laptop to datalog?

And my plugs are resistor type

Try replacing your spark plugs as they may be causing interference. Just some normal NGK copper resistor type spark lugs will work for this test, they are not expensive.

so i had got some time to change the plugs add more grounds. still nothing. if i am using the laptop to datalog should the enable on-board datalog be checked or un checked?

I have found the problem, it was a power wire from my fuel pump relay kit under the rug it was too close to the ecu. Thanks!
