Hondata

Hello everyone,
I recently acquired a second hand flashpro for my stock 2013 SI. On the stock reflash the car is perfectly fine. However when using the "Stock tuned, 6000rpm launch limit" the car idles terribly and almost seems like its going to stall, and when driving is feels very hesitant on the throttle response. I've attached 4 data logs, 3 are with the Hondata tune, and 1 is with the reflash no rev hang. The reason why I'm posting this is because I want to learn whats wrong and understand what I'm doing to my car. If anyone wants to help me out that would be much appreciated. Thanks guys

Welcome to the forum,

Post the calibration file as well and I can take a look at it.

Here you go, I've attached the reflash, and the stock tune.

I looked over the log and finding are below.

2013 Si reflash.fpcal- is running on MAF thus why it runs with no issues. The MAF could use some minor adjustments but good over all.

2013 SI Stock Tune, 6000rpm.fpcal - is running in speed density. All of the fuel tables need to be adjusted in order for the car to run properly thus why its running rough.

If you are still running the stock intake I suggest you stick with 2013 Si reflash.fpcal and adjust the launch limit to your liking.
