Chip Tune & Manual Boost Controller

[Aye6]

So I am really tempted to chip my car, however, I bought it with 82,000 miles on it (A6 2.7T about a month ago) and I'm not completely sure how good/bad the condition of the turbos are.

So far I have read that chipping the car will raise your boost to around 13 PSI (not exactly sure on that number), and that's fairly higher than the stock 7ish PSI. So basically I'm concerned that my turbos might go out after chipping. So i was wondering if it would be a good idea to chip the car and also buying a MBC to lower the PSI when I don't want to use full boost and raise it when i do. Any thoughts?

Also, I am aware that Vast can tune and lower the PSI of their chips, but I'd want to be able to raise the boost when needed.

i chipped my car at 96k. 6k later.its still running strong.spike 16-17psi taper down to 13-14psi.just do the warm ups and cool downs and u should be fine

[Mantis]

I would suggest getting an MBC and a tune, preferably an MBC with in car adjustment. I can get you a tune and MBC. PM me

Awesome I would only hope it works out just as well for me. There's been a lot of people that say that they've had no problems after so many miles, but then there's those that have run into problems, that's why it concerns me. But I don't track my car or anything so I should probably be okay.

160K on stock turbos.....was chipped from 90,000 to 160,000. No issues with turbo reliability here, but its a case by case basis for turbos. Just gotta go with your gut here.

Do you use any kind of a MBC or just running full boost all the time?

[nrowensby]

Do you use any kind of a MBC or just running full boost all the time?

You only run full boost at or near WOT... If you don't want to run full boost all the time, stay off the pedal.

Yeah I know, I just think it would be nice to have some kind of control over your boost other than how much throttle your using. But I wouldnt be surprised if I would never even use the MBC and just keep the boost full all the time, seems like not many people install these anyway.

No MBC for me. Turn down the boost? What fun is that? I was only stage 1 and needed every PSI i got!

[nrowensby]

I'm just saying, if you are going to pay for the extra power... why turn it down? If your that worried about destroying your turbo's... don't chip it.

[Kievskiy]

^ well said.

[8520]

Danger will robinson, danger.

Imo, only chip your car if you're willing to spend the 4grand plus to get it to stage 3.

With a giac chip, my turbos died at about 93k.

[Aye6]

Well I'll keep all of these replies in mind and make a decision sooner or later. Might just hold off on the chip and do some other stuff for now. Just a curious thought.. does chip tuning the car do anything other than raise the boost? (and change the A/F ratio I believe)

[Bashar Khalifeh]

Ya, its an all new map installed on your ECU, with more boost comes more fuel to prevent you from running lean, however if you drive nicely and stay out of boost range you may get 2-3 more mpg

[Johann2.7t]

If your worried why not get a tune that allows you to revert back to stock for days when your feeling more conservative.

GIAC chip sense 79k miles and am at 967XX miles on stock turbos with no problem yet!

I do drive my car fairly hard too. however i always let it warm up and wont go into boost until my oil temp is over 190ish.

i always let mine cool down too.

i've been lucky so far so no complaints here.

I have GIAC 93 and 100 maps on mine but never got to use the 100 yet due to cats and no 100 i can find in my area in maryland.

I also have my stock ECU still if I feel like my turbos are going and than I'll switch back to that.

[nrowensby]

Oh yeah, gas mileage... I drove to my S4 to MD and back on a GIAC-X 93 Tune and got ~28mpg... :D

[Aye6]

Yeah if i went with a chip I would definitely go with one that lets you switch it back to stock (don't all of them let you do that anyway?). I think I would go with GIAC though because you can use the handheld flashloader instead of shuffling through the dash with the APR chip, especially since my display is going out like everyones.

But Yeah I always do the proper warm up/cool down technique. Hmm more gas mileage too, it's a definite win/win.

[mike's machine]

28mpg??? i never get that good mpg unless i drive 60mph.
i've had Giac tune for over 50k miles with stock turbos and no issue at all yet.
maybe piggie pipes will help the stock turbos to last longer :)

Easiest question there is on the forum. YES, you should chip your 2.7t.

And no, don't bother with MBC. You can control boost with the pedal on far right.

egan - your garage list seems to be light one vehicle. Looks like a C5? How's life in paradise? Also: are there inter-island ferries?

[egan808]

yeah my c5 is my daily right now.life in paradise is in a halt right now till i get my parts for my a6...lol....yeah we had ferries here but the locals on the other islands kept complaining about traffic issues so they stopped it.it was so convenient too

I didn't want to create a new thread so here it goes..
If I consider getting the chip from ECS Tunning .. what are the different "Programs"? I just don't get it..I guess i'm now to this. I see they have 4 Programs..and it's kinda confusing. Also, I was reading on wiki that if the car is a manual, I should change the flywheel. I got a 04 a6 with about 93.xxx on it. Trany still feels good, smooth shifting and all. Anyway to check the turbos?:D (dumb questions?!)

p.s. Aye6 since the actual post (03-24-2010) did you end up getting the chip or not?

thank you guys...

^ THIS ^

Why don't more companies have ECMS?

[wofman]

Don't change flywheel, don't worry about turning off the chip (who would want to?); all you can really do (short of pulling them) is look for oil leaks on outside seal. Mine lasted with chip from 90K to 152K so far, but I now have a leak so it's getting time to replace. GIAC is best. Not dumb questions.

[Romania]

Thank you. I will talk to some mechanic that has a lift and maybe he will be willing to look for leaks . I know from time to time I get a few little drops under the car. I have not realized if it is after a long/short drive or any other symptoms. Are you guys saying that APR has the capability to switch modes on the chip? Would that be the ECMS (i'm just taking a guess...again i'm new to this stuff...:) What does ECMS stabd fir anyway? elecronic control mmmmsomething system??

What is the difference in these two, besides price? :)
It has different items listed under: "Kit Contents"..but i'm still lost between programs..

I actually haven't yet. I'm tempted to get it done this summer, but I have since stuck with the advice to chip only if I have enough to go stage 3.

[onyrmom]

Be sure to call VAST for comparison shopping before you buy anything. Their chips do all the program switching that APR or other tuners do, and they have the capability to let you reflash your ECU at home, thus saving you a trip to a tuner.

I personally have a bit of a vendetta against APR, but I won't go back into that again. Read this thread if you want the long and short of it.

As for what a "program" or "map" is, it is a set of limits that are defined as to how hard the ECU can run the motor. Limits on boost, timing, fuel/air ratio are the big ones.

For example, a 91 octane program will have a certain maximum allowed boost level, while a 100 octane program will have a higher boost limit, because there is less risk of detonation.

Sure, all modern motors have "detonation sensors" bolted to the block to detect detonation and retard timing if it occurs. But this is very hard on the motor and turbos, and will destroy it quickly if you are constantly relying on the detonation sensors to "back off" on your boost, etc. The purpose of the programmed limits is to get as close to the detonation threshold as is possible with the fuel quality available, without having ANY detonation, thus preventing the need for the ECU to put you in "limp mode" to prevent the motor from destroying itself.

There are other various improvements that the tuners do...increased data sampling rates, for example, provide faster ECU response time to changing engine inputs (throttle position, etc). But the boost, timing, and AF ratio limits are the big ones.

Also, consider a methanol/water injection kit. Methanol is a "combustion rate decreaser" which effectively acts as an octane booster, allowing the ECU to advance the timing without detonation. However, if you skip the methanol and simply inject distilled water into the intake, this buffers the compression and combustion process by adding water vapor to the intake gas stream, which has a high specific heat coefficient.

Translating to English: if you squirt water in your intake, it will cool down the intake air and be easier on your turbos and motor. The trick is making sure you inject exactly the RIGHT amount of water.

Here's a Wikipedia article that explains in detail.

Essentially, water injection is turbo insurance.

What type of chip are you running. Looking to get one just not sure what to get tbh. Soo many out there.

I do in fact have eyeballs. Just looking to get something and there was a thread on it so I wrote my question there.
