C7.5 APR Stage 1 100oct : [email protected]

[DGVR6]

I've been testing APRs Ecu/Tcu tune, finally found time to go down to the track. Making a thread to post my results.

Car 4405 & "BLACK"
DA: -766

First time slip stamped 7:44PM
This is the first run of the night with ms100 on 93 map.
Used 5.5k launch by just holding the gas down and letting off the brake, resulted in little wheelspin but shifted harsh into 2nd. Car otherwise ran strong down the line.

Second time slip stamped 8:03PM
Second run of the night, still on 93 map to let ecu adjust to the ms100.
With this I used sort of a launch method in my 6mt, I can't let off the brake obviously like a clutch, so I just dumped it. On the upsweep I would let off at 3.5k-4K, hooks up quick without over powering the launch. 1-2 shift was butter smooth and so was every other shift throughout the run.
Eyes opened when I looked at the slip.

Third time slip stamped 10:08
Car is labeled BLACK for some reason, guess they didn't get my number. I kept opening my windows With the heater blasting, numbers started to fade.
This is my best time after about 3 more runs on 100 map, just couldn't hook up at all no matter what I did.
I wasn't going to play with air pressure since I have nitrogen and no air compressor anyway. Trap was awesome otherwise.
Looking at this slip, it seems like 100oct file would be good for 11.1xx if I can get it to stick; or if anybody can get it to stick at that.

Sorry for any mistakes, I'm on the run right now lol

Nice runs, would live to see how it does on just 93 oct

[ntsantos]

Is that a record 4.0T stage 1?

Do you think it would have differed? He ran the 93 map with race gas in the tank. Surely all knock would have been eliminated with 93 in the tank in that air. But race gas is sometimes oxygenated and that might help things.

[Chris Morales]

DGVR6, the 11.2@121 run is fantastic for the 93 map regardless of what was in your tank. Excellent! At what track did you run?

Thanks Saxon, I really can't wait to see how Uni does on stage 2. With the stage 1 speed you're trapping on 93, it sure was on its way for 11.4xx with the right 60 and 330.
I'll definitely get some 93 runs in soon.

Yes

Thanks Chris, these runs were at Atco raceway.

Sounds like what the B8 guys recommend for the best launch control method. Good runs OP.

[kouzman]

Impressive!

I dont think traction was an issue for you. Low 1.60s for the 60ft is damn impressive, almost drag radial times! I could only wish for such 60fts!

[Ze_Nardo6]

Almost, but not entirely irrelevant since he was still running the 93 map.

As Chris stated, I would imagine 93 pump would have been plenty sufficient given the temps of the evening on the 93 file. If it were 80+ degrees with a higher DA, your argument may make more sense.

Great ET/trap OP!

its very hard to say who's right and whose wrong. I dont think there is enough data out there for anyone to know the answers except the companies tuning these cars. a 2mph gain with the switch doesn't seem like a big difference but i guess from apr's figures they only show a 20whp gain with race gas.

i know on my apr tuned s4 i would pick up power and trap speed by going with race gas even in the colder temps, but i also logged the car and saw that timing was higher due to the race gas compared to what it would achieve with pump gas.

i'm obviously not trying to discredit his times as they are awesome! i wish i could get the same traction that he says its lacking lol!

100% agreed. We would need to see logs.

[DGVR6]

I'd have to say regarding race gas on the 93 map, Saxon is most likely correct. How much timing advanced on the 93 map, I have no clue.. I forgot my cable.
Seems to me around a 1-1.5 mph gain over 93 with the essentially 97.5-98.0 octane mix I was running that night. I'm sure the 93 calibrations were maxed out.

Traction was not an issue until I switched maps over and the temps started to plummet. I was pretty lucky to get there before that

What does the nitro in your tyres do? I know the gtrs run that set up
Would that help traction?

Nitro just pretty much helps with keeping pressure stable within the tires. It's less prone to air pressure fluncuation caused by ambient temperatures or heating/cooling of the tires. Also doesn't lose pressure as much as air throughout the months

Could very well help if your tires heat up after every run and want it to stay around a consistent pressure

nitrogen is essentially an upsell (in my industry) as it doesn't change as much in temperatures and keeps the tires at a consistent pressure and typically you don't lose tire pressure in the winter time like normal air.

That would mean APRs 93 tune is pretty aggressive

Yep.. I'd still have to log timing, ign knock, fuel trims

Ah thanks for that. I don't think many places supply it near me anyway.

they typically "request" higher ignition timing than necessary as the computer will compensate depending on the conditions. technology is great!

[Chris Morales]

Well at the least it doesn't seem that APR's current stage 1 tune is lacking anything performance-wise compared to Unitronic's.

[DGVR6]

Right, the trap on my signature with the b8 s4 is a good example as that was a 93 map maxed out.
Unitronic didn't have a 100/104 map for the s4 though but did advance timing quite a bit on the "aggressive" 93. I would not see that on pump.

Well at the least it doesn't seem that APR's current stage 1 tune is lacking anything performance-wise compared to Unitronic's.

Definitely not, APR is producing some fast cars. I do like the tune, I'm sure I would've been trapping 124 if I completely ran straight 100.

Ah thanks for that. I don't think many places supply it near me anyway.

Revolution will do Nitrogen fill for you, heading over there tomorrow to have some 'bits' done to the '7 and will probably ask them to do a Hunter laser alignment check and Nitrogen inflation at the same time

Do they? I'm due some new tyres so will go there and get the hunter alignment at the same time. I removed the front resonators today mate, miles better.

Regular air is 78% nitrogen already. I found this article informative as to why pressuring with "pure" nitrogen is a waste of money: http://www.edmunds.com/car-care/shou...-nitrogen.html

[P_G]

They'll be pretty close to the best price you can get if not the best for tyres when you include fitting, balancing, Nitrogen and disposal.

Nice that you're happy with the resonator delete, gets better after a few runs out and the bedding in period is done.

If you want consistency in pressures on low profile performance tyres it is from experience worthwhile because Nitrogen molecules do not permeate as readily as Oxygen etc. or put it another way the 22% including water vapour that will permeate through the tyres. For standard tyres on a Ford Focus for example I'd concur it's not worth the money. However if you also get it for nothing or a few £/$ then why not?

ATCO is home to many a record run. Fast track for sure.

Right. APR in the past was not known for putting out the most aggressive maps so it's nice seeing these posts. I definitely am shopping multiple different tunes now.

So true. Not to discredit the times in this thread, but chances are if you're talking about a national record on any platform it was done at Atco (or maybe MIR) this time of year. I would love to run there one day. Just a 1600 mile trip for me.

There a black hole at the end of the strip at this time of year

Nice work!

Trying to understand how you launched. I assume for the first run you used launch control with 100% throttle and kick-down switch engaged at 5.5k rpm and for the second run you did the same but took your foot off the brake before the engine reached 5.5k rpm (i.e. at 3.5k-4k rpm). Since you have the APR TCU tune did you try to launch at lower rpms by just giving 50% throttle or 100% throttle without kick-down switch? That should give you 3.5k or 4.5k rpm if I guessed your launch profile correctly.

[DGVR6]

Nice work!

Thanks Arin

Yep, first run was foot flat on the gas with the kick down engaged, 5.5k launch.
2nd run was exactly how you described.

I'm still playing around with launch control so I haven't successfully used the lower launch limits yet.

[DGVR6]

Went to the track last night, didn't get many runs in, someone blew their motor out on the track.
Was testing the launch control settings in APRs TCU tune running on shell 93.
-1000 DA.
Car 4406

3.5k launch

Personally, I feel the upsweep method still works best.

[saxon]

That time is still very impressive for stage 1

It seems 1.6 sixties are the key to low 11's

[MikeDwerks]

Killer. Backed up your others pretty much. Maybe the 100 octane on the 93 map does give you a little something. If you would have pulled a 1.65 60' would been right back at 11.3

Is that neg 1000 DA, or just a dash?

Super jealous of those weather conditions

[saxon]

Right. APR in the past was not known for putting out the most aggressive maps so it's nice seeing these posts. I definitely am shopping multiple different tunes now.

I know with my unitronic tune I was pulling nearly 5* of timing with a "bad" batch of Sunoco 93 octane. I went back to my normal shell 93 and no timing pull. Still ran 11.6@120 with 5* of timing pull and not using launch control :)

[DGVR6]

Landing good 60 will get you into the low 11s without a doubt.
Yea DA was at negative , I always take advantage of novembers weather up here lol
