Analog Sensor Choppy Signal

[EGAJohn]

I'm having an issue with my analog sensor inputs on my new build. I had two Integras, one was my track car and this is my street car. I crashed the track car a long time ago and took the engine setup and put it in my street car.

The track car had great analog signals and the datalogs were always smooth. That car had a P75 ecu with S300 v3. My street car has very choppy analog signals and everything is connected exactly like my track car the only difference is this car has a P28 ecu with S300 v3. The sensors and everything were taken from the track car so the only difference is the chassis and ecu.

I originally had the sensor grounds running to SG1 and moved them to the S300 analog grounds with no difference in the datalogs.

I attached two datalogs from each car.

Have the capacitors been replaced in the ECU?

I'm not sure. The P75 was from a mostly original DC4 and I installed S300 at my shop but the P28 I purchased second hand with S300 installed already.

If there's some components I need to replace let me know what they are and I may even have them already.

Normally it doesn't bother me but right now I'm having fuel pressure issues and these datalogs are making it difficult to monitor.
