Default BEF - cold start Delete - 09-11-2017, 09:55 AM

Just wanted to share my experience with the cold start delete.

Previous to doing my BEF the car would hesitate when cold and driving a min after starting. After doing some research it aligned with the valves needing to be blasted and considering the millage it made sense. The valves were done and the same issue existed.

However once I removed the cold start here was no issue again. The gain was two fold as now I don't have a noisy start up as well.

+1 Similar experience here, jerky behavior during cold start.
Did you set it all the way to 0? I have it at 5s from the 65s default.

Some cars run better with it, others better without it, not figured out why the difference.
