I have had this issue happen to me once at the drag track shifting from 1st to 2nd , and now it is happening frequently on the street whenever a jolt from the clutch engagement is happening. The ecu seems to be going into limp mode where any throttle given to the car will not allow it to drive. I can shut the car off while coasting when this happens and start it up and it will resume back to normal operation. In the attached datalogs you can see the throttle being deprressed with no acceleration. In the other datalog you will find the iat and ect are maxed out all of a sudden along with other issues while driving, until the car is restarted.
Car is on S300 with Hondata CPR ignition.

Re: Ecu seems to be going into limp mode
It is not limp mode, it is something either inside or outside the ECU pulling the voltage down. The VCC rails go to 0V and the battery voltage shows 1.5V.

Re: Ecu seems to be going into limp mode
Thank you for looking at my datalogs and the info on my problem.
The problem has been solved. I have traced the voltage dropping due to a faulty relay.
Thanks again
