Your plan of action to change tunes and your shop stating that it needs a retune is smoke and mirrors.
Stating that it's running rich without even checking the air fuel ratio and getting actual data to support that claim makes absolutely no sense.
Any shop that recommends changing tunes to correct an issue like this doesn't have a clue what they are doing. These cars are target based systems. They will achieve the target that is set. If you wanted to diagnose you should flash to stock and check mixtures then. Tuning to correct an existing problem (without even verifying it with actual data is absolutely ridiculous.
Any difference in smell at the moment would be simply due to flashing or adaptations being cleared.
It pains me to see people approach things with assumptions and then form a plan of action not based on any real data.

Your input is noted. Thank you. So- if we're going to be critical here, I changed tunes because when I contacted BPM and asked them about transferring the tune to my name and out of the previous owners name, you guys wanted a lot of money. It gave me a bad feeling about your approach to customer service.
I get the feeling had I paid the transfer cost and retained a BPM tune, you'd not be as publicly critical of my approach.
Thank you for contributing to the thread. There are a number of other issues that have been corrected on the car since re-flashing re-tuning to include my rev limiter during warmup now works, despite being told by BPM that the warmup rev limiter had not been removed, the car is running a lot smoother and stronger. Whether or not the car starts running rich again remains to be seen. What corrected the richness, at this point, I don't know. Was the shop right or wrong? I don't know.
What I can tell you now is the car is running much better.
I did not, and will not, criticize your tune. I'm willing to agree that it may be a byproduct of re-flashing then re-tuning. There is no need to be defensive of your tune and there is no need to be critical of me or the trusted shop I chose to work with.
Since we're critiquing each other, and all. |
wow, they didn't let you transfer the name for a tune even though the car changed owners? That is cheap as shit. More reasons to go Alpine.
