Need to make some adjustments to my cold start tune for the winter. Whenever my ECT temps are below 150 with cold temps out side and i try to drive the car I get a lot of timing misses and bucking going on until the car warms up. Below are the actual values in S300, can anyone recommend some changes that could help or eliminate this? Unfortunately I don't always have time to let the car fully warm up before I drive it and with winter coming I'd like to fix this.


Under the Ignition Compensation tab:

ECT temp on top, ignition advance

-40 -28 32 67 123 168 302
28.75 28.75 19.00 8.5 3.0 0 0

I doubt you need to tune your ignition compensation.

Do you have a wideband?

If so, you need to monitor your air fuel ratios & determine if the issue is ECT versus Fuel tables that need to be tuned...
