T5 Performance Tuning: Who's done it?

[Transporter]

I was trying to write a short reply letting you know I have a DSG auto, but the forum insisted that my reply be at least 10 characters long. I thought I would add some useless dialog to appease the forum gods.

I just checked mine (fully loaded 2.5TDI 4Motion) and it cruises between 1600 and1800 even on slightly up hill in 6gear, the 5gear is the same rpm at 80km/h. The engine rpm are in all gears max. 1800 when driving normally.

Some big numbers there. I've looked at Superchips. Mainly because they appear to support VW Motorsports, although not sure about racing 2.5's. I'm reading as well. Lots to check out.

I reflashed my 2.5 with Superchips about 2 weeks ago and the difference is night and day. Just amazing how it has livened the car up.

Now the proof for me is that the Mrs said it is nicer to drive after the remap - so if she is noticing it, it must be true.

Mikinoz, I was also looking at the Superchips, similar price but only comes with one tune. Has there been any improvement on your MPG since chipping? Or are you burning more because your being a lead foot now with all that extra grunt?

[mikinoz]

I am not driving the car, the little lady is, but she hasn't noticed a decrease in economy, just an increase in performance.

It for me was always going to be Superchips, they are in my view pretty much king in TDI tuning, hence their involvement in VW TDI race tuning overseas.

I will dyno it again soon.

[Ivo]

I have ordered the Viezu tune. Will keep you informed on how it performs.

7spd DSG in 103TDI MV cruises at +-1700rmin @ 100km/h and 1850 @ 110km/h in 7th on the MFD not analog cluster. Did a 250km round trip yesterday and averaged 7.8l/100km with cruise control set on 107km/h on the MFD in 100 zones and 117km/h in 110 zones.

Also confirmed Superchips for the 103kw/340NM TDI MV is about $1000 in Australia and delivers 128kw/441NM.

How's this for good.

132kw van. Took 6 bikes to brissy, 3 in a trailer, 3 inside. gear for 5 guys. all up approx 1.5 ton of stuff. Syd -> bris. 1 tank! 8.1l/100 on the way up and 8.4 on the way home, sat at the speed limit on the gps all the way, so ~118 on the speedo in the 110 bits. with a trailer!! couldn't believe it.

Lot to be said for a bit of grunt, Pete

My previous diesel manual T4, 79kw would sit on around 2500 rpm on the highway at 100 ks, and the fuel consumption was higher on the highways/freeways than around town as a result

Other way around now with my 06 diesel T5 auto. Much better on the freeways sitting around 2000 rpm at 100 ks. Fuel consumption way better on the freeways than the burbs

And that's excellent figures. How many ks has yours done now?

We get the same RPM from our 132kw 4 motion 7 SP DSG, I was getting 1700rpm at 100km p/h and about 1850-1900rpm at 110km p/h.
On the freeway at 110km we get about 8.2 l/100 and about 8.8 with the cruise control on.

I've just installed a Superchips Bluefin tune. I'll see how it goes.

I'm keen to monitor performance/consumption on my next interstate trip.

[mikinoz]

Just a tip, I ran through a can of LiquiMoly Diesel Purge today and it is possibly placebo, but I think there is a smoother delivery of power.

Vieze V-Switch Tune

I have a Viezu V-switch, got it last week. I have tried the Performance/ Economy blend tune so far (approx 830km). Noticeably more power, smoother through the entire rev range. Not much of an improvement in MPG though, but definitely not worse. I may have been a little heavy footed with it though so MPG may actually be even slightly better again. It had a real surging feel to it like it really wanted to go, was great on the highway over taking 80-140kmh range. It was also good from a standing start! If I was not concerned about trying to lower my MPG then this would be a great tune.

I am now testing the Economy/Performance Blend tune. This tune is focused more on economy rather then performance.

I also have the full Performance tune to try and a full economy tune to try.

Customer service from Simon at etechremaping who is the Australian agent for Viezu has been very good.

Hi Ivo

Can you tell me how much your Viezu system cost?

Cheers

It was $738 including deleivery.
