auto-blip

Lol yea definitely wasnt planning on using it in traffic. The car gets enough attention with every "cool guy" wanting to race or telling you to get on it.

Also, you get a bigger blip at higher engine speeds

I'd certainly hope that to be the case. Regardless of what the torque/power curves look like.

I just bought one. Hopefully I'll install at weekend. Unfortunately, I can heel-toe comfortably on the street, but I am having trouble keeping a steady brake pedal while blipping. I experienced this at Turn #1 at Palmer last week, which is a pretty complex turn - curved uphill off a curved straight, blind apex, sweeping downhill corner that unloads the front. It is pretty intense for sure!

I am only doing 3-4 track days at the moment, so don't get the chance to practice under real pressure, so I am selling out! I will throw away my "purist" boxers and t-shirt!

I think in our cars T1 Palmer should be done in 4th. Going to third seemed like a waste that just unsettled the car and you ended upshifting the car right before or at the jump headed into the big T2 late apex. You can carry a lot of speed through one and track out to the grass (before the pavement ends abruptly) By the time I figured out what gear to run the track I never got to go back.

I'm all for technology. I think the auto blip is pretty cool. I also agree that, for the price point, it should be more polished(plug and play OBD II port).

The car my mustang replaced was a 2011 M3 with with the double clutch transmission(DCT). The transmission was probably my favorite part of the car(or the V8 that reved to 8k rpm).

There are major design differences between an automatic transmission and a manual/standard transmission as most of you know I'm sure. A DCT/SMG/PDK transmission are manual transmissions that shift automatically(press of a button/paddle/etc...)... not to be confused with an automatic transmission that you can shift manually(paddle shifters, etc...). Automatic transmissions don't generally shift that fast and don't generally hold up to track abuse.

On my M3, the DCT allowed me to take one driving input off my plate and focus on others, which increased performance else where. It was pretty nice. I do rev match my mustang. I purchased the steeda pedal before my car ever arrived. I was able to heel/toe without the pedal, but the pedal just makes it easier.

I will say, for most driving organizations, rev matching is a required skill to move to the advanced group. I can't tell you how many NASA check rides I've done for HPDE 3 drivers wanting to move to 4 that haven't made it due to not rev matching(required skill in the NASA passport/log book checklist). Kind of interesting if you think about it for those drivers that accomplish it through a DCT/SMG/PDK.

Great information guys, i appreciate all the input. i will definitely learn to master the heal/toe eventually because i do plan on moving ahead in the sport.

A little bit tangential to the topic, but does NASA even suggest that getting checked off for HPDE 4 with a DCT/SMG/PDK (or a conventional torque-converter automatic, for that matter) should limit those drivers to tracking in cars so equipped until they can demonstrate proficiency with doing the rev matching all by themselves? If not, should they?

There is no feedback of engine speed to the auto-blip unit. This is where the OBDII would help a lot. I think the ECU decides what that the throttle response should be relative to the throttle pedal signal.

Got to be honest. First time at the track I didn't get fast enough/confident enough to go that quickly at T#1. I was cautious so as to get a good straight line brake on the curved approach that I slowed below the 'threshold' for 4th. I will try that next time.

 

[Optimum Performance]

Completely understandable. Lots if things to hit ;)

 

[JamesinLittleSilver]

Thanks for all the input guys! Hard to thank one person though I will give a double to Norm for chuckles. Only one track day for me and ran in 4th almost the whole time. But have been just started working on H/T so the information is great.

So after a week or so, I am getting used to the gadget, you just have to go through the concious to unconcious learning process when changing your shifts. It works well and the stability you get from constant brake pedal pressure heading into turns (in this case exit ramps!) is much, much better. As I have chatted with several gear heads after confessing to the purchase, a lot have admitted they aren't good at heel-toe either...one guy commenting that a successful rally-cross driver had won many events without doing it!

I think the product would benefit by adding a "gradient" button that counts the number of sequential shifts and adjusts the blip strenght based on that (in lieu of a more sophisticated OBDII based system)

Anyway I have shifted from "I might have wasted my money here on a crappy mod" to "I have definitely wasted money here, but I enjoy using the new mod!"

 

[S550Smoke]

well good job staying positive lol, wasted money seems to be part of the process sometimes so it is what it is. im glad to have the garageline and steeda pedal mods. time will tell if I even use the dam blip.

Not to be argumentative, but just more as FYI - I really like rallycross too, and usually run top 3-5 in local events, even won in SA once. Vehicle dynamics are way different in that discipline - speeds relatively low and constant sliding on dirt surface means that not rev-matching on downshifts really doesn't upset the chassis any more than it already is. Big deceleration into a paved roadrace turn is much different

I figured. In order to keep the argument going, I was alluding to soem "accomplished" drivers don't use the technique well!:cheers:

So I bought the Auto-Blip from @socalmustang and finally got a chance to try it out at the track and all I can say is wow! What a huge difference! I was in the habit of either rev-matching before beginning braking or having to brake, lift, rev-match, brake again, giving up time and upsetting the balance.

It took a few laps to get the delay and blip level right, but once I did it was good to go. Here's a video in action.
