Now that my current track tune has been tested on track and it's pretty much solid, I'm starting to revisit my street tune.
I'm concentrating more on low and mid range tuning right now but I'm starting to think the general lack of flow mods on the car is starting to show.
Great gains so far low and mid range though, looks all nice and choked up top though... time for a downpipe?
Obviously most of this is the laughable stock turbo but it does make me wonder what opening up some flow could do.
Mods:
E40 fuel
Airtec FMIC
Custom tuning via Cobb ATR by me

Compared to my last E45 street tune, you can see after 4500 rpm or so it's not so flow happy.

Did your impression of the BC's change? Different settings?Another track day under my belt in the FiST.
Weather was amazing this time around. Mid 60F as the high, 50's in the morning. Sunny. What a difference from the 98F day last time.
Slowly getting my track legs back and getting used to the car. I went six seconds faster this time around, getting there, slowly but surely. The car still has a good amount left in it but I'm taking it slow as I still have six years of track cobwebs to clean out. Tried a couple different ways to drive the car this time with different success. I can tell once I get fully comfortable with car I will want to loosen up the chassis. Right now it's pretty darn stable but I can tell it will be faster with the chassis set up looser.
Now that I'm going faster in it I can predict a LSD could be in my future if I keep tracking the car. It would do some really weird hopping stuff in hard third gear corners on power and I would even get some wheel spin in 4th on track out in some places. That and not being able to put power down in off camber corners started to get a little frustrating, especially coming from tracking an AWD Evo.
I also think I need to get an exhaust of some sort as the car is way too quiet on track with a helmet on, hard to judge the RPM.
I used the GoPro for the first time this event too. You can see from my video I didn't mount it in a great spot to see all the track. You get to see my mug though.
Now, more data!
First, some engine data logs. Here is an overlay of a session from this event with an overlay of a session from last event. It's fairly obvious it was a much cooler day by the charge temps. Huge difference! The interesting data to note is that coolant and oil temps show a much less difference. They are obviously cooler this time but not by much!
Blue plots are from last event in 98F weather
Red plots are from this event in 65F weather

Next up is G-force. One lap. Lateral and Lineal. You can tell pretty quickly from looking at this overlay that I was much quicker this time and that is shown in the offset. Also note higher Lateral G's of 1.02 max compared to .99 before.
Left and right Lateral G's are shown as positive/negative.
Accel and Decel Lineal G's are shown as positive/negative. Note much harder braking this time.
Blue plots are from last event

Here is the video. Unedited. One session. As noted camera position sucks and the car is way too quiet. First lap is my warm up lap so you can forward to the start of the second if you wish.

No, about the same. I upped the front dampening and it helped a bit on track out understeer.

How much did you lower in the front? Any rubbing under compression at track?
I'm getting ready to buy the BC's and hope that I can run the R888:
225/45/16 - 9 - 8.7 - 23.8
I had 275 nto1's on my X lowered on KW V3's so I'm used to a little rubbing on full lock!

Haven't updated this thread in awhile as I was just updating it over on fiestaSTforum...however now that I was banned and ALL my threads, tech info, etc was deleted off that forum as a foolish move on their part I will be updating this thread a bit more on this forum...
Stay tuned.

With some time off over these holidays, spending some time with family and friends, seeing how the other forum members and staff are dealing with the "incident" and just the type of people on the Fiesta forums made me realize some things that are more important to me.
I like real life better.
I'm leaving all the Fiesta Forums, happy to had contributed what I did and I wish you all the best in the New Year.
Go forth and modify.

That's one of the thing I hated about my X, the back seats didn't fold down.Hey look, I haven't fully left the forums yet.
The Fiesta comes in pretty handy to bring parts for my Evo home:

But, I could get 4 Volks wearing 275's NTO1's in the back seat for trackdays.

I'm not tracking the Fiesta anymore as now I am back to tracking Evos. This time in my VERY mildly modded Evo 10.
Figured I would post some info from my last track day so the data geeks (like me) can compare the data between my Evo and my Fiesta.
BTW, I was ten seconds faster in the Evo compared to the Fiesta on the same track.

2014 Evo GSR with SSSL package
Power:
Resonated test pipe
AEM intake
GM 3 port boost solenoid
ID1000cc injectors
Blaqops walbro 255lph fuel pump kit
91 octane conservative track tune @ 298whp
Handling:
Apexi ExV coilovers, 8k/8k spring rates
Whiteline rear swaybar, set at medium
Yokohama Advan AD08R street tires, 255/35/18
Enkei NT03+M 18x9.5 +27 wheels
-3.0 front camber, -1.8 rear camber, 0 toe
Brakes:
Raybestos ST43 front pads
Girodisc SS rear pads
Torque RT700 brake fluid
My current goal was/is to do as little as possible to the car to make it track worthy, safe and fun without going over the top and making it ****ty to drive on the street.
Overall:
It was my first track event in an Evo in about seven years. It was my third track event since starting track events again after a seven year break. I tracked my Fiesta ST the last two events. My goal for this event is to take it slow and get used to not only tracking an Evo again, but tracking an Evo 10 for the first time ever. I was very happy with the car, it took me about two sessions to get more comfortable with the car but overall it felt very familiar and was like driving an old pal but with new tricks. I was MUCH MUCH MUCH faster than I was in my Fiesta ST. I dropped myself down to Solo group from Open (Advanced), which is basically this organizations beginner group because I wanted to take my time getting back up to speed. Passing with point by only so there was a bit of traffic but I currently don't care since I am just taking my time getting comfortable again.
Suspension:
As listed above, I am using Apexi ExV coilovers with 8k/8k spring rates. In my Evo 8 that I tracked heavily I used the same coilovers but in 8k/6k and ended up going pretty quick in them at this particular track. The car felt pretty good over all so far but there is a good amount of body roll still and quick transitions are a little unsettling. If anything it's reminding me to keep my inputs and corrections smooth. The heavy ass Evo 10 could for sure use higher spring rates but again, my goal for this car is to not make it uber track centric and still be a teddy bear on the street. The alignment felt great. Even though the spring rates are on the soft side, the car was pretty progressive and not under steery or over steery but felt pretty balanced. This could, and most likely will change as I start going faster with the car. I will most likely attempt to tune this a bit with dampening and sway bar setting.
Brakes:
Granted I am not doing blazing fast lap times at this track yet in this car but the ST43/Girodisc SS/RT700 combo felt GREAT. Very progressive feel, zero fade even though I was being really sloppy with my braking and in some braking zones, holding the brakes much longer then was needed. I really couldn't have asked for better brakes this event. Once I knew they where up for the task, they where out of mind for the rest of the day.
Tires:
I started the day with my normal street pressure, around 36-37psi. They felt a little squirrelly about half way through the session. Came in after my first 20 minute session and they where 42-43psi. By the third session I found that they felt the best for me and the way I was driving that day, around 38 psi hot. I was very impressed with the grip level of the AD08R's. When I tracked my Evo 8 years ago I ran R-compounds and honestly these feel pretty close when they are at their best, but did fall off a little like street tires do. The steering response felt great and they seem pretty good communicators but we'll see how that changes as I go faster with them. They are quiet on the street for the type of tire they are and while having really stiff sidewalls, have good ride manners.
Power:
I chose to not run my normal E85 for this event, but to run 91 octane. I did not want to haul a ton of fuel to the track. The 91 tune felt... lacking on the track. The Evo 10 is a heavy car and it needs all the power it can get. I ended up with some knock as well so I decided to put a mix of about 4 gallons of 100 octane in the car to help it out. This is where Tephra V2 came in real handy because I had some alt maps already setup for leaner and more timing. So I think the car probably ended up around 315whp or so at some point in the day. I can tell you I am not going to make this a habit as 100 octane at the track was $8.99/ Gallon. Cost me a small fortune to keep the tank topped off the whole day. I did this to not run into any fuel starvation issues with the 10 that every body talks about. I think I am going to look into running a Ethanol mix next event, maybe E30 and just bring a couple 5 gallon jugs to save some money!
So overall a successful event for me and I am already looking forward to the next one.
Data from the event:
Single fastest lap from the OP 2.0 Standalone logger. I chose to run my AEM intake with lid off like I do on the street. After looking at these logs I think I might put the lid on next event. Ambient temp was probably around 65-75*. Looking over the logs and using RPM and TPS shows me I have a good amount to work on for next event.

Wow that is quite an aggressive alignment on that car! I'd imagine you wouldn't want to run that much camber with low treadwear tires for long on the street as you'd get a lot of camber wear. How do those AD08Rs compare to say the Direzza ZII that you have run and the RE050As that come stock on the Fiesta?

From my experience, toe is what kills tires. I ran -3.4 on my Evo 8 daily and it was fine. I run -2.6 on my Fiesta ST daily and it's fine. All have zero toe.
Hard to compare the AD08R's to the Z2's as the AD08R's are 255 and the Z2's are 215, plus the Evo has so much more mechanical grip than the Fiesta ST, it makes it almost impossible to compare, to be totally honest.
The one thing I can say is that the AD08R's are quiet while driving normally and the Z2's sound like 10,000 angry bees chasing after you.
