So, i installed my begi s1 with 460cc injectors and mspnp9495 and i drove it for the first time today. I was doing some tuning and the ms was resetting every couple minutes. I have attached the datalog. I did mess around with the grounds on my wideband but didnt disturb the ecu grounds. I have my wideband grounded with a second nut on the post between the valve cover and the TB.

Resets are caused by bad grounding or bad 12v, you aren't experiencing comm resets so it has to be something else. You can tell it's not comm resets because the SecL counter resets back to zero whereas in a comm reset it would continue counting up after the reset.
Check your wiring. Just try grounding the wideband somewhere else for the heck of it.
Have you used vampire taps on any of the ECU wiring? They tend to damage the wire severly when used.

The only vampire taps i have used are from the dash lights dimmer for gauge power. I haven't changed any grounds but i will clean them up a bit. Is there any way to tell how close my 12v is?

so, matt at diyautotune says that i am getting a clean 12v. I will be checking the resistance on my 460cc injectors to make sure they are high impedance and in spec.

So i solved the problem. I cleaned up the wideband grounds and battery terminals. The problem just disappeared after that.
