Revo Logs...

B8 S4
#61

The revo timing values look like the timing values on the stock rs4 tune…a high compression naturally aspirated engine. When JHM supercharge these cars, logs show timing values had to be dropped way down. Same on the B67. The JHM pump gas tune for the supercharged B67 shows timing values of about 18-20 degrees requested. It also shows that if conditions are shit or anything is wrong, retardation steps in pretty strong, pulling 5-10 degrees like it’s nothing.

Pretty funny to see that revo runs 25 pump-30 degrees race of timing on a supercharged car, and timing retardation is almost nonexistent… and REVO thinks running a point rich will protect everything. Odd.

Is the surface pro going to have enough horsepower to capture what’s needed? I seem to recall a few had dedicated VCDS netbooks and they struggled running VCDS for logging. I know the surface pro isn’t one of those older Atom netbooks, but just thought I’d raise the question.

It’s a surface pro 2. Basically a mini laptop. I actually Run AutoCAD Lite on it so cannot imagine it being a problem. I will try a bit later tonight.
Just got home from picking up the car at KMD. They have done 2 customer cars so far. Both Black s4s. They pulley itself is black so looks just like stock. Great bunch of guys over there. They convinced me to get a P3 boost gauge as well. Love the look of it!
So my impressions so far, since its rush hour in NJ I haven’t gotten to go crazy plus I wanted to give it time to adjust. But I can absolutely feel the increased power. As others have said it give you more down low where you notice it during normal driving. My face the entire way home ;D
Once I get it broken in a bit I will grab some logs. Prime or anyone please let me know what would like to be done and I will get some data.
AI would like to go to the track and get some 1/4 mile times. I am really curious on how it compares to APR/GIAC. Thinking of Englishtown in the next few weeks if anyone is going.
Oh lastly I have an SPS and the tune does come with a 100oct map as well.

Log these values if you use vcds 12.12

A couple dudes are quite excited for their upcoming pulley release in the az c7 sandbox.

[QUOTE=well_armed;9722031]I found a coupon code for the upcoming REVO pulley release.

So have had the tune since Friday and have gone a couple hundred miles. Its like a whole new car MUCH more enjoyable driving around with the stage 2.

i was able to do a few logs that Saxon recommended. I am not sure why all the values are 0 in the knk columns.
I have a busy week than am headed on vacation but after that i will get some more logging and plan to hit the track.

As far as feeling both my wife and friend were Shocked at how much more pull the car has. its comparable to what others say about apr/giac.

I did a few 0-60 with the P3 vent gauge and on firday night was getting 4.1(no LC) and 3.95(with LC). today i did a two more runs after logging and got 3.81 and 3.96. not sure how accurate that is but I can assume the car is still adapting to the change.
also on a second gear pull looks like the boost was reading 14.5 psi

thats all for now!

I’m not as experienced in reading logs as Ron or Pete, but at first glance it appears they are much more in-line with what we’re seeing out of APR or GIAC Stage 2 timing-wise.

#68

can’t see much from the logs. sampling rate isn’t good.

from the limited data… MAF (kg/h) isn’t anything impressive, neither is boost. bypass valve opening also in upper rpms… @6500 rpms and max maf ~10%.

Would like to see data in a particular gear (3rd) and with decent sampling to really compare.

#69

I’m in the office so I can’t review the logs but based on Tsivas comments bgm didn’t use turbo mode or group by which is critical to getting good sampling… Also, like he said really need 3rd/4th gear to tell anything which is why I prefer logging at the dragstrip since it’s legal and safe… I’ll take a look at them tonight at home though as I was out of town most of the weekend…

#70

just run from 2000 RPM to 7000 RPM in third gear. Simple enough. Standardize it so you guys all do the same thing, and then upload it to the site Mistro created for us.

audilogs.com

it’s pretty solid for having your awful spreadsheets of data output to charts.

#71

I was able to get a few logs in last night before a run in with the police. He was very cool about it but it ended my session quickly.
https://docs.google.com/spreadsheets/d/1N1SMfmlR9SWE2VGjoBC8qL-HlEVtnXNjSBv4MZ-IEos/edit?usp=sharing

I was tying to 3rd gear pull on the first run it kicked to 2nd.
second run 3rd to shift
3rd 0-60 with launch control.

Once again i made sure that Turbo and group was checked and i still got nothing in the timing columns. Not sure what is up with that unless to tune is not pulling any timing at all.

#72

yeah, sounds like revo/the tune is saying ‘Audi’s safeguards are a bit too pussy like, since they don’t know what fuel their customers will use, so let’s tone it down a little knowing we’re selling a 93 octane tune and our clients aren’t idiots.’

You can’t forget that the stock tune is sold to people ranging from california 91 octane piss to people like us in the northeast who use 93-94. You also have it being sold in Africa…Asia…and you have customers who aren’t shy about forgetting to take it for service and who will put 87 in.

So perhaps they’ve adjusted the knock sensitivity, allowing them to run a little more timing without seeing the car pull timing when you have good fuel and it’s cool out. when it’s hot out though guys have mentioned that the car pulls back the reins quite a bit.

You can decide if that’s an appropriate strategy or not.

#73

try doing a timing log (knock detection) of all 6 cylinders in multiple repeated runs in 3rd from 2000-redline… get temps nice and hot and see if its pulling timing. only checking 2 cylinders here.

also looks like they have issue with bypass opening up a lot in upper rpms.

#74

Tune looks tame. Timing is allowed to advance over 20 degrees but at low IM pressures with bypass open. Tame. Lol the new face of REVO

#75

why can’t the tuners control that fucking bypass?

#76

Took APR and GIAC a little while to learn how to make requested boost dynamic based on conditions. That was their response after Revo brute forced things by dumping the underboost safeguards and set requested boost through the roof. Also figure that the guy that wrote Revo’s original tune left, and they probably don’t have the guy that wrote their V2 tune either after all the Stasis shenanigans so what you end up with is a tune basically equivalent to APRS2V1 but with a little more timing. Either that or they realized you can’t run that much timing at full manifold pressure too late in the process and decided to just proceed anyways and let the bypass open.
