Proper tune on my car

[fa5matt]

I was wondering if anyone can help out with my car I am currently on the StockTuned flashpro basemap currently
heres a datalog I did earlier or tried to and the tune I am currently on

Are you still running the Takeda intake and Skunk exhaust from when Ed was helping you? If not, let us know the mods you have and if you have any more planned in the near future.

For this one, the part throttle fuel trims are very bad which makes me think you still have the intake. WOT fuel isn't too bad, but definitely needs some work. The knock is minimal which is good.

Let us know the currents mods, and any future mods planned.

No back to stock intake, but now I have a Js racing exhaust 76mm thats it no plans in the future as of right now.. Going to go supercharger but I don't think I am ready for that as of right now still need to buy new injectors etc

Okay. Well if you just want to tune it to have some fun with while you wait for your SC package, I can start you on my stock intake basemap and just clean it up for your car if you'd like. Usually I like to go in and tune all cam angles, but since you plan to go SC it's probably not worth all your time to make datalog after datalog so we can use a completed basemap and clean up the fuel for your car.

Let me know.

For sure man I would like the motor to be healthy before I go SC lol thanks for the help

Okay sounds good, give this one a drive and we will see how it looks. For the datalogs, shoot for 20 minutes or so with as much stop and go driving as possible. On the drive, we need one wide open throttle (WOT) pull from 2500-8600 so we can see the WOT fueling.

Alrighty, I can continue this tomorrow and keep you updated it's late for me right now haha appreciate it bro!

[EFICU]

Sounds good. You're welcome.

Here's some datalogging I did today one of them I was just at idle at a car wash haha

Interesting few datalogs there. I am curious to see if you might have an issue with the MAF sensor. I am going to switch you to a MAP based tune and see how it looks. Take this one for a drive when you can, again shoot for 20 minutes or so with the one WOT pull in third.

I remember when I switched one time it made my car jump at 3krpm and my vsa light etc came on

Yeah in your original datalog the fuel trims were very lean. I didn't think much of it, so on my calibration it's very lean for part throttle fuel trims trying to keep the fuel in it. It's not actually lean, just the fuel trims are positive. So my first thought was wrong injectors or something, then I looked at the WOT fueling and it was very close. So something is going on at part throttle fueling, which is controlled by the MAF sensor. We'll see how the next one looks here and then we'll figure out the best path forward.
