Wondering if anyone has changed over to the new ACN91 map?
Is there much difference?

It feels noticeably slow compared to the 2.01 91 map. I will switch to the regular 91 map and look at the data logs. If I don't see any timing drops, no ACN for me.

Which gasoline do you use?

I use only Shell 91 and the car seems to like it.

Let me know what happens when you run the data logs.

Thanks

I use Shell or 76.
Here's a data log with the standard 2.02 ACN91 map, 3rd gear pull. I don't want to try to change the map right now because my AP goes into recovery mode every time I try. There is still a bug with some 2007 models.

Thanks for this info but I'm not sure how to read these data logs.

How does it look to you?

How does this compare to the original Stage 1 - 91 log?

Here's my 3rd gear datalog with 91 Octane 2.02 Standard maps (non-ACN). I have no mods other than the tune. I had to slow down at 5,500 rpm.

I'm not an expert, but based on what I learned on this forum, it looks good to me. The timing is really low compared to piggybacks, but that's how Cobb prefers to tune the car.

The log data looks alot like the ACN91. I'm leaving the old tune. Thanks for the info.
