Need help tuning

Post by chrisconig0 »

hi i have a 2015 si with a ktuned 3.5 intake and a invidia q300 cat back exhaust. i have a flashpro for my car. so my problem coming is that i can drive the car fine (afr is a little off) but if i sit and idle too long the car goes into limp mode and throws throttle body codes and im not sure what to do. i have 2 datalogs- 1 idle and 1 city driving

We would need to see which calibration you're running to better determine the issue. Sounds like you're running an AFM based calibration which will most likely cause a similar issue to what you say. With the K-Tuned intake, then should be tuned speed density (MAP based) to get the best drivability.

Yeah that's a MAF based calibration which is most likely the cause of you issues. It needs to be tuned speed density IMO.

Are you planning to add any performance mods in the near future?

No problem. If you plan to add mods in the near future, I can put you on a completed files and we can make it dialed for your car. It may not make as much power as a complete custom tune for your car like I generally prefer. This way saves both of us a lot of time to get you going quickly, then when you add more parts we can spend the time to tune it properly.

Let me know though, I can send that over and you can start making datalogs. It's very simple to tune it speed density and it will almost 100% remove the issues you're experiencing.

Okay, give this one a drive when you can. We'll see if the codes persist, and go from there. Make the datalog in the 20 minute range and get a clean third gear WOT pull from 2500-7500 in there so we can see the WOT fuel.

Looks pretty good. I don't see any codes in the system. Does the issue appear fixed on your side?

Gotcha. You can just let it idle at home if you want. See if you can get it to do it and hopefully a code or something will pop up we can see.

Yeah that doesn't show anything we can use unfortunately. Did you make a datalog for the idle? If so, post that, I might be able to see the code in there.

What does it show under the "DTC" tab?

Either way, keep datalogging when you drive the car in hopes we can capture the limp mode issue and try to diagnose it.
