: First DE at Sebring

Wow, what a day. This was my first DE event ever. I went with Chin Motorsports last Sunday and had an absolute blast. I had a full 3 hours of total track time available to me, and was only able to get in about 2 and 1/2 (oil temps were getting a little over 300). Guess who my instructor was? V-sam on here (John) with the Silver 05 V. How cool is that?!

For weeks leading up to the event I watched a Sebring instructional video about 5 times a day, but the first lap around the track for me it was just sensory overload. I took it easy for the first session, getting used to the track, turn in points, etc. and then starting in the second session I started pushing it a bit harder. One thing I must say is this car held up great. Once I got comfortable with the car and the track, my instructor had me try later braking points using ABS braking, and I couldnt believe just how quick this 3800lb car could decelerate. Pads held up good, didnt get any brake fade even into the last session. By the next event I'd like to have an oil cooler and a decent harness setup; I was sliding around in the stock seats pretty good. Im probably going to go with the Schroth ASM 4 point with the shoulder straps mounted to the rear seat belt bolts, and for the oil cooler I'm torn between a Mocal matrix cooler or drop the $$$ and go with the Ron Davis radiator with an integrated oil cooler. Other than that, probably get some dedicated track pads (Carbotech) and call it a day. Tires still have plenty of meat on them (NT-05) and I'm going to replace the rotors soon with just NAPA blanks.

My only little "issue" I had on the track was turn 17. I learned the hard way that you really need to brake a good bit where the braking zone cones are, turn in towards that cone in the middle, straighten the wheel a little and brake some more, then make the full sweep around turn 17. I didnt scrub enough speed before turning in, and while turning in I realized I was carrying too much speed, so I tried to brake a bit (bad idea) and right at the corner workers station the back end came out and we went for a little ride, but I had the tires pointed in the direction of the slide and was looking into the slide, finally got the back end to settle and all was good. Definitely learned my lesson; a.) scrub more speed before turning in to turn 17 and b.) trailbraking is not for rookies. I'm sure John can chime in on this as well, it was quite a ride!

Heres a video of my cleanest lap without traffic. I had the camera mounted on the driver's side front bumper, but for some reason there is a ton of wind noise and it started to fog up a little. I think I just didnt get a good enough seal on the GoPro when closing it in the case. Anyways, turn down the volume and enjoy. Feedback is appreciated! This lap was a 2:49.8.

Here is another lap with some traffic:

Here is a video playing around with mounting points on Johns Silver V. I wish I would have taken another video facing forward, watching him outbrake the Porsche GT3's in the corners, lol. Damn 2GB memory card!

I cannot wait to get back onto the track, I am addicted.

Awesome... Some spots on that track don't look too forgiving if you lose it!
I can't wait to do my first track day. It'll be this year sometime for sure, just need to choose the best location within a respectable driving distance..

Great writeup and I'm glad you had lots of fun. That is what it is all about. If you do this enough your competive side will come out and as you start putting down some fast laps, it will be really cool to see how many cars (more expensive, much lighter, etc.) that you can hang with.

It is addicting. I'm really hurting to go, I haven't been in a loooong time.

Awesome! My wifes uncles live in Sebring and I need to get my arse over there sometime.

BTW Check out this thread about your high oil temp. Not saying you weren't seeing legit high oil temps but it is a very common problem due to the grounding offsets.

ah, I forgot to bring that up. I actually tried the star washer fix to help grounding the wire, and that didn't do crap. I think the next step would be to get the reflash done at the dealer.

Question: could a tuner do the same reflash that the dealer does, while tuning the car, and if I get it done at the dealer, if I get the car tuned would it "reset" the dealer fix?

sebring is a great track to learn on. the track is wide and you can carry a lot of speed through the turns. Easy on the brakes too. Ive done a few days there in a few different cars. Need to watch out on the pads. the more aggressive the pad the more they eat your rotors. I like to use a hp+ pad. They don't kill the rotors. I usually out brake most cars in my group that are not caged cars. Our braking is awesome. It helps to make up most of the difference in power compared to lighter cars. Glad you had a good time. hope your saving up because this ends up costing a lot when you do it a lot lol.

AHHH I typed you a whole nice explanation of both items you asked and accidentally erased it so I am gonna go with the brief version this time.

The ground problem is that it can be ANY one of the X number of grounds, not just the hood prop. <explanation deleted>

The PCM is an entire flash to the hardware that cannot be changed without an entire re-flash. Thus anybody who flashes over top of the existing "tune" will wipe it out entirely and you will be left with what they flashed. The same for both tuners and dealers. Here is some light reading that I basically typed previously: http://www.techterms.com/definition/firmware You are flashing new firmware each time you update the PCM.

As for a re-flash fixing the problem I never heard that. I though the dealer fix was adding a ground to the sensor. *goes to read the thread again*.

here is what I got off of cadillacfaq.com regarding the oil temp issue:


ASI Resolution - Engine Oil Tempature Gage Warning (Call TCSC and Reprogram IPC Module) #04-08-49-017A - (Aug 3,2004)
Document ID # 1542045

Engine Oil Tempature Gage Warning (Call TCSC and Reprogram IPC Module)

2004 Cadillac CTS-V

Built prior to breakpoint 40181396 and build date April 14, 2004

This bulletin is being revised to add the correct information. Please discard Advanced Services Bulletin Number 04-08-49-017 (Section 8 -- Body & Accessories)

Condition

Some customers may comment that during or after aggressive driving, the engine oil tempature display in the DIC has a higher than expected reading or the oil tempature warning has come on.

Cause

A ground offset between the engine oil tempature sensor and the instrument cluster affects the tempature reading and may indicate a tempature higher than actual. the actual oil tempature should be in operating range.

Correction

Engineering has released a software update. Using normal SPS reprogramming procedures, Technicians are to reprogram the IPC modual wit an updated software calibration. Prior to reprogramming, technicians MUST contact the Techline Customer Support Center (TCSC) at 1-800-828-6860 (English) or 1-800-503-3222 (French) to obtain Vehicle COnfiguration INdex (VCI) nymber for assistance in modifying TIS Pass-thru RS-232 Baud rate from 115200 to 57600.

The new calibration will be released beginning with TIS satellite data update version 7.4 to be available on 7-21-04. As always, make sure your TECH2 is updated with the latest software version.

Dealer Action

Please contact all customers that were told they would be called when a repair became available. Distribute this information to all dealership technicians and service advisors.

For vehicles repaired under warranty, use:
Labor operation: N4199
Description: Module - Instrument Panel Cluster (IPC) [shy ] Reprogram
Labor time: 0.4hr

Interesting, thanks. I still need to look into this but I am amazed that it JUST started after I changed oil...doesn't make sense.
