Well, wasn’t exactly what I was hoping for but I did achieve one goal of breaking into the 11’s. Made 5 solid passes, attempted a 6th(ran a 13) but I shouldve called it after the 5th run. The car had a REAL hard time with the 1-2 shift today. I haven’t had it hang up so much in one day ever, slowed me down big time. If it wasn’t having the shifting issue, I’m pretty sure all of my passes would’ve been sub 12 today.
I ran with stage 2 v3.0 and no dsg tune. Still waiting for my file to be built… Other performance mods are AMS boost cooling system, 034 test pipes, and awe track exhaust. Running 19inch wheels at 20b a piece with PSS; JHM rotors front and rear.
1/4 tank on 104 map.
Yup, APR and no problem. Take a look at my post (2 above yours), that is the most pronounced video I have of the issue. There is a big delay between the end of 1st gear and engagement of 2nd. Could it be because of the increased power from v3.0? Trans not able to keep up is my guess but I’m not really sure since I didn’t log the runs. In the past on v2.3 it would very occasionally hiccup at 1-2 and generally only on the first pass, but it was nothing like todays behavior
Okay now I see what you’re referring to. This is a situation where an in-cabin (go-pro) view would help (like with Prime’s videos).
Something’s up for sure. And you’re a 2010 like Prime. Seems like APR just didn’t do all the testing necessary to release this update. And to be clear, I run an APR Stage II setup, so I don’t have an agenda against them (their conduct against this forum notwithstanding).
Sounds like this isn’t a finished product for 2010 owners.
Also, I’ve never had a hiccup as you describe on my 100 passes or so at the track. DSG has been flawless each and every time.
And in that regard, I agree with what some others have posted that a TCU tune is worthless for pre-B8.5 cars. Audi seems to have gotten it right the first time.
Go pro would’ve been nice, I’m planning on going again tomorrow so I’ll see if I can make that happen.
Also regarding the hiccup. It wasn’t really an issue for me in the past but have you really never had a minor hang up on the 1-2 shift even when the car was stock? What year is your s4? 2010’s have the weakest dsgs, 11’s are a little better so that might be why you never experienced it
Thanks. Yea stock trans but updated ECU tune (v3.0). Reason I said I shouldve quit after the 5th run was because the shifting issue from 1–>2 wasn’t getting any better. If you look at my post (6 above yours), my 6th run had the worst hang up.
Car was fine for the 2nd and 3rd runs but every other run it had the 1-2 shift issue.
Actually I misspoke. 10’s and 11’s are the same hardware wise for the trans. Not sure then, I thought I remember reading Primetime and some others on AZ experiencing what I did… Primetime can correct me though.
That aside, this hasn’t been a serious issue for me until now. It was a rare occurrence previously. I’m hoping the dsg tune can resolve it
My car definitely hangs up on 1-2 shifts sometimes (2012 APR stage 2+). From the logs and everything I have looked at, it seems to hang up when I get wheel spin at/during the 1-2 shift. It’s the only time my car revs to 7200 in my VCDS logs, and I think the wheel spin is causing it to over-rev and then hang up to happen as a result. When it doesn’t hang up, I get pretty consistent shifts at 7000.
Going back-and-forth with Ron when it first happened, he speculated it was wheel spin, and the testing I have done since then seems to back that up. I’ve only been able to make some 1/8 mile passes recently, but dropping the air pressure seemed to help with the issue. I’ve got it down now to where it only seems to happen at higher tire pressures when I also seem to have minor traction issues on launch. Also interesting is that it happens almost exclusively when I DON’T use launch control. I have had it happen on probably 15 of my 50 or so passes, and probably 12-13 of those were without using LC…
Good stuff! Grats on the 11 second pass, seems like the car put it all together there with the 1.6 60… Thought you would have a better mph… It may be the timing equipment like Thompson where the one lane reads about 2mph low… Your trap was almost 116 on the other side… Jran is correct I believe a little wheel spin causes the 1-2 hangup… I used to get it say 1 or so out of 10 passes, pre tcu tune… Depending on how bad it is you’re losing a tenth or so from it…
What air pressure are you running? It’s not an exact scienece but you want to try and run as high as possible w/o getting spin… Tires and weather conditions also have a lot to do with it obviously in relation to how warm the track itself is and your tires… Depending on how busy the track is I try to heat my tires by turning back and forth constantly on the return road and then hot lapping if possible… Given it was 70 and looked to be sunny I’d probably start at 38-34 or 36-32 and go from there… I always go 2-4 lower in the rears… If it’s real cold, especially the track itself I’ll go down to say 26-22…
Would be nice if you can make the go pro happen as I’d like to see some in car vids and it will let you see how your technique is on staging and such… Focus on the little things as well to ring out as much et as possible, IE shallow stage as best as possible, pick the middle of your lane and make sure you’re perfectly straight so you don’t have to make any adjustments mid run, keep the wheel as straight as possible with little steering movement… All those little things add up… Thanks for sharing and looking to see how you do today…
As far as I know Ron, Milan has one of the best an most reliable timing systems. When I run there I never noticed a difference between left and right lanes.
Everything else mentioned is accurate. I leaned a lot of of what I do at the track from Ron.
Thanks Jeff I appreciate that! Gotcha on the track wasn’t sure since he had such a better trap on the other side on his only pass on that side…
You going today? Will be neat to see you guys make some passes against each other… You’ll probably get him by a few tenths, but will still be cool to watch… Looking forward to the vids and results! Have fun guys!
Thank you! Yes, hoping for a bit more since I have the recipe for a seriously good time. Love this forum, advice below is what I have to try next time out.
This makes sense, I remember on the runs it did hang up those were when I broke traction at the line slightly. I didn’t have the equipment to play around with tire pressure this time out. I definitely needed to drop down a few psi… I’m making more power + have lighter wheels than last year so I wasn’t expecting it to break traction at the line like it did.
Yea I noticed Jones does it in his videos. I’ll give it a shot next time
Thank you! There are so many little things that go into squeezing out the best time possible like you mentioned. I’ll need to be more wary of that next time out (might happen today but not 100% sure yet). Problem is they have a bracket racing event today so I would only get to make 2 passes with a lot of waiting around…
I wish I played around with tire pressures. Just didn’t have our pump on us unfortunately. Both of the 11.9 runs were hot lapped, didn’t have to wait around at all and thus the tires were nice and warm. For the other runs I was sitting in the staging lanes quite a bit because of some idiot motorcycle guys breaking down mid track every other run…
All great information guys. Thank you for the advice, I sense next time out will be even better! The hang up had me worried but I knew there had to be a logical explanation for it
