i am running a neptune rtp in a p28 managing a mildly built lsvtec. ive been tryin to use the anti theft features of the neptune software however when i run up into high rmps the ecu resets and triggers the anti theft either shutting the car off completely or send it into valet mode with the rpms limited to 1025 rpm.

i done really now whats causing the ecu to reset and would love to know how to fix this if anyone can help.

 

You should try disabeling the anti-theft features and see if your ecu still does that.

 

Is there a Check Engine Light accompanied with this ECU reset and or anti-theft valet mode/complete shutdown?

x2 on disabling the anti theft mode and seeing if the issue remains.

 

Disabling will keep it from shutting the car down, however, you may still feel the reset and/or see the check engine light blip. It could also be a misfire causing feedback through the system.

If you setup on board logging so that it runs constantly it should also create a new session when it resets.

I'm not sure if I asked you to, but if you want to take a datalog on the PC with the beta version that's available and send it along with your calibration I'll check and see if there's anything out of the ordinary.
