REVO Software Fuel Cuts

[cyanidecologne]

All of you audiziners we need to band together. If you are experiencing fuel cuts with REVO software we need to make REVO aware of this. They claim that they have never heard of anything like that and seem fairly unwilling to do anything to remedy the situation. So once again if your car is running in limp mode which can be quite dangerous post up on here and lets let REVO know about our issues.

I suggest you check your cam lobe and follower first. You can always tune down on revo with revo select or have your dealer do it.

Checked both the cam lobe and fuel pump both are in perfect condition. Had the dealer flash it back to stock and it ran perfect now im reflashed back and the fuel cuts seem to be even worse than before.

I've changed to the forge dv, breather tube, and pvc, and I'm having the same problems...but I rarely push the car to even notice it though. Ever since I tuned down the settings, its been acting better. I still wish it ran the way I first got it chipped.

[a4b7]

keep us updated if you are still in contact with revo..i want to know if they want to pursue a solution.

I will continue to work on this id like to get as many members as possible to voice their problems that way i can show them im not the only one.

i havent had any fuel cuts....what symptoms you experiencing? did you maybe get a bad flash????

Its been flashed twice now and my tuner even called revo while in my car and revo claimed it was a problem with my car not their software. I will randomly lose all throttle response completely random and intermittent sometimes it will last as little a 1second or as long as 30 seconds.

I think I went into limp mode for a little while today, no or very little boost, it was wierd though it only seemed to really affect 2nd and 3rd.

Thats exactly where it happens to me unfortunately im Tiptronic so im stuck there when it happens.

[artinmoTTion]

I'm familiar with multiple "minor" codes adding up to a miserable experience with a limping B7, unexplained by the Revo dealer, but went away without the Revo software.

I know that there was an update from Audi on the software at some point over the past 6-8 months, and was wondering if Revo then similarly updated their software based on that...anyone know?

[snosk8tr123]

I have GIAC and my car goes into "limp mode" all the time. Feels like no boost at all. as if my pedal is completely disconnected. then it comes back up in 10-30 sec... i really have no idea why this happens

[a4b7]

when i was first flashed..i would be able to peel out for a while and won't be able to gain traction. I would spike to ~22/23 and hold around 20 for a while.

After my dv went out..i changed it out to the forge and upgraded the pcv(as stated earlier in the thread)

Now sometimes I floor it to test, I cant even hear a chirp. My boost goes up to 7/8..sometimes 14/15 if Im lucky. Some days I can get to boost up to 19psi no problem. I dont know what is wrong with the car, that is why Im holding off any further mods to the engine.

[Quattro]

hmmm......thats very odd a4b7...who did your tunning? maybe they put your settings higher than what your car is capable of doing and the car is not letting the revo settings happen..if that makes sense....

check for timing and knocking on your car see if that shows up with anything....

how are you testing for your boost? have a boost gauge? check for anything unplug'd or not held on good...maybe that could be a problem. any air escaping will cause all sorts of problems...
i am boosting at 22 MAX and holding boost around 15-20 at times...

[a4b7]

I will check tomorrow. I have the vei digital system. Everything seems to be in working order. I dont have a vag com to check timing and knock. I might bring it back in one day and see if they can check it out.

BTW what is everyone's vacuum at...ever since the forge dv..mines been at -27 (with stock dv it was -22/23)

[lak2881]

Never had this problem with my revo software and hopefully i never will. Sounds like a pain in the @$$.

[RedS-line]

nice too see some people posting boost levels. people with revo should post their settings, i.e. boost,timing,af. i believe stock revo is 6-2-9 but a nearby dealer here puts it at 7-3-9. anyone running higher numbers than that without fuel cuts?

[A4 JooN 2.0T]

After i got my testpipe ive been getting the fuel cut very often when i go WOT.....I spoke with revo because i wanted to get a hi flow pump and was wondering if they had the file for it. They told me developing was in progress...So pretty much if your tune is more agressive thatn 6-3-9 and you're stage 2 say hello to fuel cuts at WOT....

im always at 6-3-9 drive to work,7-5-9 when im off and 8-5-9 on a hot ass day = CEL -__-

[Slo.Mo.Shun.]

On hot weather fuel 8 works best

[Mike@PureMS]

20k+ of problem free driving with my APR. :)
Let me know if you're fed up and ready to switch!

Well Mike im thinking this is a pretty good opportunity for a "sad revo customer group buy" on APR programming, and fuel pump.

[redhott06]

i experience minor fuel cut here and there, but my cam is shot, so i believe thats why. my autotech pump should be here pretty sooon!

[RedS-line]

joon- boost 8, timing 5 on a HOT day? isnt that backwards? wouldnt u run lower boost and reduced timing when its hot out? HID are you talking about air/fuel ratio? why is that. timing 8 is for race fuel.

[ed@mtl]

I experience the fuel cut from time to time. Yes, I do have the Revo software.

At one point I even had the Autotech fuel pump. The fuel pump help a lot. I went back to the oem one because of the cam issue. The aftermarket fuel pump would accelerate the cam wear which I didn't want to keep checking.

[D-techniK]

I am a big APR fan and I was actually comparing Revo to decide but if Revo isn't willing to stand by it's customers or atleast try to come up with a solution then going to head over to APR instead.

[RichTJ99]

Is this happening to anyone with Stage 1 Revo (or is this a 2+ issue)? I was also planning on making a purchase in the next week or two but now I might start watching this thread to see how things develop.

[Quattro]

I think this might be a few indivduals who are experiencing this. I have several friends running stage 2 and no problems. It is very strange to hear this, the oniy thing I can think of is that the fuel pump might not be working to par. It could also be that you are running tuning more than your car can handle and the fuel is not there when needed, but this would only explain at high rpm or fast speeds.....

[cyanidecologne]

i went straight to stage 2 so i dount know if stage 1 customers are experiencing the same issues.

[Mike@PureMS]

For any of you considering the fuel pump upgrades, check out this thread. APR's pump is by far the most reliable product on the market. VW Motorsport even uses it to win the ADAC 24h race on the Ring!

cyan, what mods do you have to support stage 2? you running atleast a testpipe?

mike aren't apr fuel pumps like 1k?

Test pipe and full creative exhaust, Creative Autoworks suggested the stage 2 when i got the exhaust.

[artinmoTTion]

in my experience, fuel cuts weren't even the problem, I don't think. The car was Revo stage 1, and exhibited a combination of strange behaviors, EPC and CELs, symptoms kind of like Pete's post here: http://www.audizine.com/forum/showth...&highlight=epc
Sorry I don't have the whole list, was VAG'd at a dealer. Symptoms went away when car was switched to stock mode. Not sure if something was on its way out and the software hastened its demise, or if it was fking with something else.

No hard driving on this particular car, suburban daily driver. Do 2.0T's have an N75 valve to go bad like 1.8T's?

i dont run that setting again it was just a test which = to CEL......READ MAN!

revo is a more agressive tune "sad revo customer"??? LOL at least i can change my settings around not what the dealer set for me.....fuel cuts happen to almost any car trying to make more power on the stock pump oh maybe if apr was as agressive and not conservative you would be in our shoes.....research before you say some dumb shit

[Mike@PureMS]

APR pumps are indeed around $1k. But to put it into perspective, so is an exhaust system.

An exhaust might net you 10-15hp, all in the upper RPM band, 4K+

An APR fuel pump will net you closer to 20-25hp all in the middle rpm band, from 2k to 5k, where you do 99% of your driving.

APR's spent over half a million dollars in testing fixtures for their fuel pumps. It's by far the best quality pump on the market hands down. Their test fixtures are absolutely amazing in terms of the number of tests they perform to make sure the pump isn't going to seize, like that other brand.

[Quattro]

I think some of the fuel cut issues have to do with the settings people are running...for instance if you are running timing suppper high (6+) the stock pump can handle it till a point.

The stock fuel pump is decent, but from what I have been reading and what people have been teaching me is a new fuel pump is needed to actually boost up timing to 6+.

[RedS-line]

would a dealer be able to tell you had an apr rebuilt fuel pump by looking at it or through scanning it? i want one

If you remove the APR sticker from the side, the pumps will look identical.

If the normal Stage 1 revo is 6-2-9

What is the typical stock from the dealer settings? (4-1-5)?
