I just got the K&N sri intake. I have the flash pro. I loaded the K&N base map calibration and now i feel like my car is running a little weird now.

Can you post a datalog of 10-20 minutes of driving to see how it's acting?

I don't know if this is long enough datalog but I can upload another tomorrow.

Overall it's not too bad really. We can definitely make it better though.

Do you have any planned mods in the near future, or is the K&N SRI the only mod into the foreseeable future?

Okay, since you plan to add some mods in the near(ish) future, we can do a quicker tune on it now and then if you still want my help once you add the header and exhaust we can go in and do a thorough complete tune where we tune all cam angles. We can do that now if you wanted to, although it's time consuming on your part making twenty minute datalogs. But doing it this way, it should get make it fun to drive and super safe for now. It will still take a couple revisions to dial it this way, but the long route takes 10-12.

Either way, for now, give this one a drive and see what you think. I have it set up to be a hybrid calibration, but some K&N cars like to be speed density tuned. But try this one out, see what you think, and make a twenty minute datalog with at least one wide open throttle (WOT) pull in third gear from 2500-8600 so we can see the WOT fueling too.

I don't mind going the long route, and I'm really grateful for you helping me out. Here's my datalog from this mornings drive with the revision you gave me.

Sounds good, we can go in and tune it properly. I'll have you make one for datalog on this next calibration to verify the primary o2 sensor is working right before we move forward. Take this one for a similar datalog and drive, just be sure to get a clean third gear WOT pull. I want to verify the o2 sensor is working properly before moving forward. The fuel in WOT was a little bit leaner than I would have imagined for the first file, so if it's still lean in this one the o2 sensor isn't working properly. But we'll see, take it for a spin when you can.

Okay it looks like the sensor is working just fine, so that's good. So we can go in and tune it. We will start on the 0* cam angle with vtec at 4500. The 0* cam angle is the least powerful, so don't get discouraged when it doesn't feel as strong. It basically lays the foundation for everything we do moving forward. So take this one for a spin when you can, keep datalogging like you have been for the twenty minutes and a third gear WOT pull. Your driving style in the datalogs is great.

Vtec cracked a little bit louder probably because the 0* cam angle

Yeah the 0* cam angle sounds wilder than it feels for sure, so that is probably what you heard. Here is the next one, we will now move to the 15* cam angle with vtec at 4500 again. Take this one for the same type of drive and datalog like the last one.

Looks really good. I made some adjustments for the next one, we will now move to the 30* cam angle with vtec at 4500. Take this one for the same type of datalog and driving style.
