I want more power from my TDI!!!!!!

[Passat CC]

Has anyone done any ecu flashing, remap or upgrade for a Passat CC 125 TDI DSG?
Can anyone recommend a product they have actually used?
I'm looking at REVO or BLUEFIN just want peoples experiences with them or any others
How much? Where from?

[team_v]

JMAC deals with bluefin.
He is a member on here and could probably tell you more about them.


Custom code also do some work with the diesel engines.
They have a nifty DPF delete on the diesel golf 125.

What's a DPF delete?

[team_v]

Removal of the Diesel particulate filter which allows more air to flow quicker through the system.
With a Retune after the DPF delete the 125kw Diesel golf owners are set to see 170-180kw and 450-ish NMW of torque.

"more air to flow quicker" c'mon!

The DPF is a filter to trap soot in the exhaust. It does this like a cat, but one that has closed channels, and the incoming gas is forced through a porous wall into an outflowing channel. Traps solids nicely, but highly restrictive. Required for all diesel cars to meet euro V emissions. Some more info in the stickies in the Diesel section.

The trapped soot is burnt off as temps rise, and if that doesn't occur via normal driving, the car forces a regeneration and dumps extra fuel late in the combustion cycle to heat the DPF up considerably to burn off that soot. Thing is it's never 100%, and several years down the track that DPF is going to permanently clog. That's the downside, but you're at least 100-150k off that as a minimum.

I just had a simple explanation until your inveitable reply
Would be interesting to see how a deleted passat would go.

[Greg Roles]

Pretty good I reckon, the extra weight would tame the wheelspin and the 2000rpm torque spike nicely.

Will removing the DPF void my warranty? Is it safe for the car? Is it legal? Will it make a different exhaust sound?

[team_v]

DPF removal will void warranty.
Not sure if it is legal or not, i know that the car has to meet those euro standards to be sold but i am not sure if it has to comply with them after it is sold.

It should be safe, basically they just remove the DPF and retune the engine to allow for the decreased resistance.

Not sure abot the exhaust note.
Shouldn't affect it though.




Hopefully Gavin or Greg can chime in with their greater wisdom.

Warranty voided, absolutely.
Safe, seems to be, lots of positive results so far.
Legal, nowhere near.
Sound, not from what I've heard. Sound is all handled by the resonator at the rear axle.

Any ECU tuning can easily void your warranty, it comes down to the warranty claim and if the dealer can use the fact it is tuned to lay blame. An ECU tune isn't going to void a faulty seat, but if the turbo goes kapow, well, I think it's only fair to expect you may be on your own there. The cheaper tunes tend to be FAR more obvious to dealers, the better ones aren't. The main brands you read about seem to have very stable products and the chances of a problem are remote in the 125kw as it's designed to handle extra heat and thus power over the 103kw. In your shoes, with your car's age, I'd be asking if the ECU flash counter increses with the tune, thus waving a red flag to anyone with half a brain and simple scanning tools let alone what a dealer can do.

[noone]

So what are the enviro regulations on Euro cars?

Do they have to comply to their original spec or just Ausi reg's?

[Passat CC]

Do you know of any tunes that don't effect the flash counter?

[parso_rex]

Actually this ECU being an EDC17 might have one of the newer Tricore anittuning processors so it may be an ECU out job initially. you would have to check the counter would be reset during the process anyway
