I posted a thread (http://www.audizine.com/forum/showthread.php?t=214786) a couple months back when my car was hurtin' bad. Turbo was dying, no ABS, up near the "CHANGE THE F****G TIMING BELT" mileage, winshield washer pump broke, constant misfiring etc, and generally just stock slow

Well here's everything I had done/price for anyone who's currious

That puts it around $3700 in parts alone. Can anyone guess what labor costed? haha Was it all worth it. Yes and No. Yes because the car runs better than ever and I'll definately get another (at 76k) 40K out of it with prob just the occasional control arm, coil pack, vaccum leak etc. No, because I'm ADDICTING TO MODDING THE FRIGGIN THING[wrench] That being said, can anyone suggest some good shock and spring kits? After that, I think I'm all set aside from the occasional cheap exterior mods ie. some valeo e-codes, smoked tails, better brakes and rotors


So here's my boost question. Before the flash I was doing 5psi. After I got the ECU flashed with GIAC PUMP, I hopped on the highway, peaked at 25 and stayed between 20 and 23 on full throttle through the first couple of gears. Is that too much on an 800 dollar hybrid turbo. A buddy suggested a boost controller and a turbo timer or else I'm diggin the thing an early grave.

Feedback? Thanks in advance.

I'm sure someone from GIAC will chime in with an answer for you

I am assuming that by "pump flash" you mean that you simply got a basic K03 software flash. If so, you are definitely overboosting and this is normal behavior when running software that is mismatched with the turbo.

I don't see a 5 bar or fuel injectors on that list either, if you continue running it as is, the EGTs will likely eat the turbo before the overboost does.

I might recommend contacting your GIAC dealer to make sure that you have the correct software installed as well as, the hardware to accompany it.

Well, I know very little about this stuff so and confided in this guys wisdom. I mentioned how most K04 kits came with 5bar FPRs and he told me I didn't require one. In regards to the flash, he said it was a stage one flash and I could choose from valet, pump, or race.

Is it possible that I damaged the turbo already? ( what are EGT's)
How much will a 5bar fpr and some injectors run me?

That was referring to individuals whom respond to inquiries. You are the one posting an issue you are having, so you are following the guilines correct.

But you would need to get the components for the k04 set up. That would include an FMIC, custom exhaust (not needed, but recommended to free those ponies), FPR (or an AFPR), and injectors. As stated above, call your closest GIAC dealer and have a talk with them. They will tell you what injectors you will need and FPR (as stated before, it is better to get an AFPR w/gauge). You could source those out for fairly cheap price after you find out what you need. Then you would need GIAC to grant you the correct tuning.

An FMIC is required even though I won't be running that "aggressive" PC-16 file?

It is suggested to even run an fmic on a stock k03 w/flashed ECU. I myself have not gotten an fmic yet, and winter is aproaching so not too big of a concern for me at the moment.

for that much boost i'd at least be running tt225 injectors. imo a turbo timer isn't a necessity. just stay out of high boost (above 3-5psi. no boost is better) until the car is warm and let it idle a little after you get done driving it hard. talk with giac but on a k04 i wouldnt go higher than 20 psi anyway because of efficiency of the turbo.

*********,

Once again you are running a K03/K04 hybrid turbo. It is not capable of sustaing the boost levels that K04 software will demand. We flashed your vehicle with the correct K03 software for your application. If you are worried about your indicated 23psi, then run a MBC in parallel. EGT= exhaust gas temperature. Any more concerns call the shop.

I agree, this whole Hybrid thing is confusing. The manufacturer indicated it was capable of producing 210hp which leads me to believe that it leans more towards being a K04 (which are capable of 230). I can't get a definitive suggestion from them in regards to what program would work best with their turbo. I guess I'll have to go the route of a manual boost controller as you suggested. But how do I deal with all that talk on the forum about new injectors and a 5bar FPR. Someone mentioned the "EGT"s killing the turbo before overboost. What is meant by "EGT"s?

********,

There seems to be some miscommunication. From what you said you have a K03/K04 hybrid, not a K04 hybrid, running K04 software on this setup will almost certainly destroy your turbo as well. Unfortunately, to my knowledge there is no software specically designed for this turbo. Also, you need to be sure your wastegate acuator is set correctly. After that you could (hate to say it) run a manual boost controller in parellel, only parrell to limit the peak boost. Please give the shop a call with any qustions.

Greetings,

My name is *********** and I was in last week with a 98 A4 1.8T Quattro Tip. I paid $375 to have my car flashed.

I've been informed that I may have a software mismatch which is causing me to overboost. Per my conversation with *****(sorry, not sure which one) 15psi (give or take ) was estimated after the car got flashed. When I left the shop, I was pushing 20-25 - which ,as the manufacturer of my turbo has indicated, will ensure early death of my new turbo. Here is the link from audizine where I received the feedback.

People are mentioning a 5bar FPR and new injectors- both are included in most K04 kits I've been seeing online. If this is true, I'm surprised that this was something which was left undisclosed last week.


This is the turbo

Please let me know how you feel we can resolve the situation. Are there any other GIAC dealers in MA because that drive to Greenland costed about $20 in gas

Regards,

So according to the guy at east coast european, my hybrid can only handle a K03 file... kind of diaspointing since it's been said to produce 210hp... not sure if that's achievable with my current software. Unfortunately, noone has any info as to what software would perfectly compliment my turbo - oh well.

So it looks like im in the market for a boost controller


for that much boost i'd at least be running tt225 injectors. imo a turbo timer isn't a necessity. just stay out of high boost (above 3-5psi. no boost is better) until the car is warm and let it idle a little after you get done driving it hard. talk with giac but on a k04 i wouldnt go higher than 20 psi anyway because of efficiency of the turbo.

I am clueless about the injectors/FPR thing. Why do I need new injectors but not a FPR? Thanks in advance for pushing me in the right direction.

When boosting around 15-20 psi, is it common for an unusual smell to come from the engine? I don't know how to describe it, all I know is when i hit the gas hard, and boost up to around 15 or so, I smell something.

Did you get your turbo from gpopshop? If so, beware: http://www.audizine.com/forum/showthread.php?t=226637

The bottom line is that there is no off the shelf software for the turbo you bought... so you are going to have to put together a frankenkit from both the k03 and k04 parts bins

Gpop states on there website that there turbos are compared to a k04-015. AWE has a kit for it. So if you copy there kit and fallow that. This may put you in a better situation. I can't confirm this. I'm in the same boat as A4Gasm.

I had my eye on the AWE k04 kit for months with cash in hand. I gave up waiting for borgewarner to ship K04-15's (which I'm told will finally happen in December). My car needed lots of other work so something had to be done. I'm pissed that they compare it to a K04 seeing as I went to get it flashed and the shop told me it's basically a little better than a K03sport...
