damaged turbo charger after remap EDC16 Golf 5 140hp

**cruuz** · 15th April, 2013, 08:56 PM

Hello I wold like to get your feeback about a remap I did two days ago. Unfortunately at fullspeed 220km/h 6th gear at about 4200 rpm car didn't accelerate any more, white smoke in the mirrow => the charger was gone!
I did a log befor flashing and after in third gear, my intension was not to have much more torque after 4000rpm! What is your opinion abut the remap? is it really bullshit and caused the damage or was the charger faulty and misfortune?
Thanks for your help in advance!

not a brilliant tune, but it is certainly not a reason for turbo failure in such short time. misfortune i would say.

thank you for your honest answer, what could be better?

yer,its not the best tune...but take alook at the turbo map.....% increase isnt very linearturbo.JPG

Another titanium job

have a look e.g. at $E8B24 and rethink your conclusion...

yes is not very linear because i desired an early almost constant pressure progression. From 4000 rpm the torque falls down to something between 300 and 350NM there is at most 220mbar more pressure desired. Is this to much for the turbo?

ecu tuners is right. i dont think 2,4 and 2,5 bar is healthy on a garret designed for 2,2 bar. you can forget about its duty life.
also all injection realted maps were increased and high load @4000rpm scale.

You got max turbo and max inj q at highest revs... a used car would find difficult to handle that. Maybe your oil wasnt new, and other factors.. Conclusion... this remap helped, copntributed, played an important role in blowing your turbo.

thank you also for your honest opinion. At lower rpm there is at most 305mbar more, for this pressure at lower rpm on crank the compressor don't needs to spin to fast as it would need for higher rpm on crank. The oil was not new but ok. Is 200mbar more pressure at 4000 rpm to much for this turbo? iQ is lower than 57mg/stroke after 4000, original it is about 51, don't think that this is the limit (12%). my 1.9TDI 130HP holds 63mg/stroke there.

Higher exhaust gas temperatures helped to kill your turbo.

**ominimicu** · 16th April, 2013, 12:07 PM

more rpm and burned fuel makes more exhaust, which makes the turbo spin faster, if the boost control valve allows for the wastegate to open. even if in lower rpm, the pressure maps says 300mbar more, this will be achived only if there are enough exahust gases.

for me is that the turbo spined so fast, it outbalanced itself and lubrication was not enought. i courious to see how s the turbo when you remove it. Dont forget to post pics. we ll know more or less what killed it if ti stuck, burnet from speed and frotation..etc

Hmmm... if this tune killed the car, then i'm worried what the one I uploaded to a friends is going to do here! My impression was that the turbo was a gtv1749? Which is the same as my PD150 which has been running the turbo map in here for 60k miles no problem...

I run upto 1.7 bar and tail it off in the higher RPM.

From what changes I could see compared to mine the tune looked pretty tame

. So a little misfortunate I feel.

hmmmmmmmm... not really nice tune work. I think Ecutuners has right, higher exhaust gas temperatures helped to kill your turbo. BR.

**ominimicu** · 16th April, 2013, 05:56 PM

ouch, 2,7 bar? so much fuel bruning....huge increases man....if it were my car i wouldn t load this map...

am i too scared? or what? why do people increase soo much?

**poxxxy** · 16th April, 2013, 07:38 PM

Alot of VW forums seem to push the VNT-17 to those figures,

. NM request calculations I made kind of said it needed that much fuel for the power required! Although my VCDS logs show drivers requested torque as only 410nm which seems to be wrong... i'm sure its not a diagnostic limit?? Also i'm pretty sure my EGR maps are incorrectly setup/modified! Anyone knowledgeable that could help it would be appreciated. I have changed my turbo map because I thought the x axis was IQ but apparently its torque in NM? In which case it was already setup for upto 500nm torque stock. My smoke map has also been modified slightly to calibrate for 1351mg air, not 1500 with some better values.
