They both look really good. I made some adjustments for the knock, again they were in the same sensitive area for 9th gens. I took a little bigger swing at removing ignition to remove the knock this time. I also made a couple 1-3% changes to the WOT fuel since you made a pull or two, I didn't want them to go to waste since you made them. Take this next one for a spin when you can, overall it looks great.

Sounds good, so you're keeping the stock intake?

Hey EFICU,

I hope all is well.

I took a few more logs. I did a pull on the last one.

The car has been riding great and feels faster, much more fun to drive.

I should be getting the exhaust late next week. I'm not sure when I will be installing it.

I'm not going to get an intake. When I get the Kraftwerks kit it will bring a new manifold and intake.

Thanks,

Sounds good. The fuel stuff looks good. There were a couple knock in both datalogs that weren't captured. It's not the end of the world anyways, it was only a couple knock. Try to datalog from the start of a drive to capture the knock if they happen. Other than that though it looks good.

I forgot about you going SC, sorry. Haha.

I have two more logs for ya.

In one of them I did two pulls. The car needs a oil change. I'm probably going to do that this weekend.

It looks really good for the most part. We had a couple knock in a new area, so I touched up the ignition there and I made some small percent fuel changes. Give this one a drive when you can, we're getting really close.

I like the last one you made. Before when I let of the gas, the car would jerk sometimes depending on the RPMs. My car has always done that. With the last tune it was barely noticeable.


Here are two more logs. I did two pulls in one of them.

Interesting, that's good. We'll see how this one goes too then. I made some ignition adjustments for some knock in your high speed pulls in fourth and fifth, and some part throttle high cam fuel trims. Datalog a drive when you go somewhere and we'll see how it looks.

I did the oil change on Saturday, not sure if that would affect anything.

Here are some more logs. I did some pulls, mixed traffic, passing cars, and cruising.

Overall it looks pretty good. Still some stubborn knock on the fourth and fifth gear pulls, so I made a little bigger swing at it this time to remove the knock. Take this one for a spin when you can.

I noticed less to no knocking with this tune and it's smooth.

I grabbed some more logs one of them has pulls.

I also got the downpipe and exhaust yesterday, but I can't install it until I get the motor mounts.

I did have one datalog corrupt and it was the one I did 2 pulls in.

Thanks for all you help.

Yeah these look good, of course they don't have any pulls so we don't know if those fourth and fifth gear knock are gone. Either way though we have the part throttle and third gear stuff dialed which is good. Since you plan to install the DP and exhaust in the near future, we can hold off on continuing the process until you install those if you want. Or next time you make a datalog, shoot for those fourth and fifth gear pulls, or don't do them until you install the DP and exhaust. The new setup might reduce the chances for knock, but we can readdress all that again once you get the exhaust stuff installed.

Keep me in the loop on it all. Do you know when the motor mounts are supposed to be delivered?

You're welcome! I'm glad things are look so good.

Here are some more logs. I only had one knock today and I tried to replicated and I could not. Things look good.
