Stock tune N20 logs -- timing corrections
Hi folks,
I collected a few logs on my N20 with stock tune since I'm planning to flash to BM3 stage 1 soon. Seems like there are timing corrections happening regularly, so I'm looking for some advice on that. Here are the car/test details:
Logs for the three pulls are here: https://datazap.me/u/ktw/21sep2020-s...log=0&data=3-6 https://datazap.me/u/ktw/21sep2020-s...log=0&data=3-6 https://datazap.me/u/ktw/21sep2020-s...log=0&data=3-6 I'm new to interpreting logs and appreciate any feedback, but here are my takeaways:
The timing corrections are my main concern, and I'd certainly appreciate tips on potential causes. My suspected causes from most to least likely are:
Thanks in advance for any suggestions and feedback! Figure I should get this sorted before flashing BM3 stage 1. |

The stock map works with 91 and 93 octane. On California gas, it probably needs to correct itself to run on the lower octane we have here.
It shouldn't have any problems with CA gas but since this is a universal map for all US octane, it'll need to correct itself to run on the lower end of the octane it is designed for.

Thanks guys! Good to have some confirmation that my thinking isn't way off since I'm still learning how to interpret all these data. I just remembered that there are a couple gas station near here that sell 100 octane, so I may try mixing it in to get to 93 and collect new logs for kicks.
