Stage 2 Dyno Results: 2014 GIAC V1 and V2, 2014 Revo, 2012 APR

[Jones2012s4]

1k is low. It's the equivalent to 30 baro, 10' elevation and about 74.3 degrees along with low humidity.

Unless you're close to sea level and on a cool summer night, you're going to be hard set to see anything sub 800. If GIAC needs sea level low DAs to run really fast, it's kinda weak. I think the problem a lot of people ran into with these tunes in the summer time is that with the tunes, the cars were potentially slower than non-tuned cars were in similar conditions.

1000 is not low. It may be to other platforms.

GIAC doesn't need low DA. These cars need low DA. 1000 DA is not low relative to this platform and the times that have been run. I am talking about the best performance here Swank, guys are running their cars in the summer time and wondering why their numbers are so low, well sorry to break it to you, but running your car in 70+ degree weather has a noticeable difference than running it at 55 and under temps. It may not seem like much, but we have found these cars and their sensors to be extremely sensitive to temperature and atmospheric changes.

GIAC, APR, REVO, doesn't matter.

DSG vs 6MT...I looked at the fastest times and 99% of them are DSG so I expect to be slower than a DSG car.

My 60's aren't that bad but the time and ET are lower than I expected. Launch consists of sweeping it at 3-4K then dumping the clutch and shifting right around 7200RPMS. Tried holding it but the results were not much different.

Can someone look at my slips and give me some insight as to what if I anything I can do differently?

60ft times aren't fantastic for AWD but I haven't driven a 6MT S4 either. It's a balancing act with a daily driver here- the more you beat on it the quicker your 60fts will be but at some point you're definitely going to burn your clutch at least a little. On my 335xi I burned the clutch a little on the 3rd pass I ever made with the car with just a few thou on the odo. Right there I learned that car's stock clutch was crap and could barely hold stock power and I just took it easy on launch and stayed with mid 1.8 60fts because I didn't want to put a clutch in it. YMMV.

From a power perspective on paper it looks like you picked up 30-40WHP which seems to follow with what GIAC posted recently. But I think a lot depends on what exact weight you ran at and what exact temp and DA. Also, your shifting may be ok or may be slow- have to see a vid of it. Sometimes foot-to-the-floor powershifting will make the car faster sometimes it won't and sometimes the ECU will even not like boost spikes and bog a little on fast or high rpm shifts. The early 335 tune I had did that as well- quick shifts above 5500rpm caused a momentary bog but it was fixed in later tunes.

For 93 octane, I don't think you have much to complain about but logging always helps. VCDS it.

Thanks man.

I am ok with it but seeing all these other 93 times much faster than mine I expected a little more. I ran with less than a 1/4 tank of gas, temp was 65-70 and the DA was right around 1000 all night. I think the last run it was 946 and you can see on that slip 12.8@110 my 1/8 was 88MPH (going back in time) but my trap was the same @110. I would assume a faster 1/8 would equate to a faster 1/4? but my 1000 was actually slower than all but one run. How do I explain that?

Your times aren't that bad considering conditions. I ran 12.8-12.9 @109+ way earlier this summer on pump, similar DA and temp.. I'm gonna echo whats been mentioned earlier, its not that easy getting into the 11's with these cars. They are fairly consistent mid 12 second cars on pump with the right cooling setup and ambient temps, at least what I've seen in my short time with stg 2..

Short answer: It could be explained mainly by IAT, I think. I noticed that, on my stock 2014 S5 DSG logs, that the bypass valves opens and starts really bypassing boost at roughly 75-77'C. I dropped from 12.3psi on one street run down to 6psi because of this. Timing actually stayed the same or went up as boost was bypassed. This is all stock ECU behavior, tuned may be different.

My street logging at 84'F ambient showed that while idling and moving in traffic my IAT was basically starting off at 67-70'C, likely because the SC coolant loop was heat saturated in that scenario. As soon as I got on the highway and nailed it in 2nd, the IAT went quickly to 82.5C by the top of 3rd gear.

So if your first few passes netted IAT of sub 75'C and the one you were slower on the back half you crossed 75-77'C, you were likely bleeding boost and slowed down slightly.

The only way you'll know for sure is to log it. Yes VCDS is a PITA to lug around a laptop but logs are needed. I'm still working on getting my Torque app to properly log all of the PIDs I'd like and that may be enough to supplant the need for VCDS + laptop for better-than-nothing basic logging (Ambient AT, coolant temp, IAT, cyl 1 timing and boost).

I just had my 2014 s4 done with a full AWE package. Exhaust, Stage 2 with GIAC software, cold air INtake and cold front. I havent taken it to dyno yet, but I can almost say I got at least 80hp increase. Car is a completly different creature which will get me in lots of trouble if I dont smarten up =)

You have a DSG or 6speed?

Quick question (sorry if it's stupid to some of you): The Stage 2 performance pulley kit on AWE's website, does that come with the V2 of the GIAC software? Looking at getting the stage 2 kit + DSG tune, but the page doesn't mention if it's the V2 of the GIAC tune.

The actual version loaded would come from the dealer that installs the software, and the not the pulley/stage 2 kit you buy. They would download it from a GIAC/AWE server, so you should have no issues getting V2 at the time of software install; just make sure you mention that you want to make sure you get V2....

Perfect, thanks for the quick reply!
