1.2 TSI low on power

[Tex]

Hi,

So today I had the car remapped by a APR distributor,

My car spec is

66kw and 160nm

The guys dynod the car before tuning,

It only made

58-60kw and 152nm

It is DSG, in S with ESP off it did 11.46seconds to 100kph

With stage 1 tune at 98 octane it made

132bhp and 210nm

0 to 100kph was 10.3


Any ideas to why there was a big power loss, car has 110k km on the clock.

The tune was supposed to make around 130bhp but with around 250nm


What do you guys think is wrong? Maybe a turbo clean?

Thanks

What is promised in an ad hardly ever comes true.

No 2 engines are alike, no 2 runs are done with the same environmental conditions, no 2 dynos are alike, etc, etc.

210Nm (sorta, kinda, depends on the dyno and what corrections are done) is still good for a 1.2l.

Last Friday my car felt like a turd, but today it's a little rocket.

I understand that, however when I look at other 1.2 tsi and 1.0 tsi's they mostly seem to make more bhp than factory, but in my case it's making less anyway, I was really hoping for atleaste 235nm , that's still 25nm more which I think would be amazing, I am thinking of doing a turbo clean and new spark plugs hopefully that might help a little

Yes, maybe a good service would help.

1.0tsi is a crazy little thing. I can't keep up with them in my 110HP 1.2tsi 6C Cross Polo. Thing is, I have no idea about the longevity of those 3 cylinder engines.

I'd like to know your driving impression after doing the tune. I know you would have liked to have seen more out of it, but how do you find the car now compared to before the tune?

Only asking because my 1.2 feels like a right old dog most of the time. I swear my mk1 golf with carb 1.4 is way more lively than this thing. The delayed pedal, the torque limited tune, they really get in the way.

The first day I noticed a little improvement, it was the next day that it made a big difference.

For me it's night and day, not necessarily the torque, but the way the throttle comes strong after 2500 rpm, in D it is a little improvement, you do notice the a little more torque, weird thing is the gears are changing higher, would have thought they would change sooner.

It's when you use the kickdown that the car really moves, there is more lag now but when it's at it's 3000 rpm peak the car seems to just take off, that's with the DSG. Gears seem to be more aggressive and the torque hits hard when it's shifting above 4k rpm.

When in manual mode and ASR off and in first, it wheel spins like crazy in first and second and 3rd. When I'm in 4th and I use the kickdown it goes into second and just spins, I have 185s and they have some sport grip, but the tires just getting worn

With my boost gauge, I was getting 0.5 bar on stock, with the tune it goes to 1.1 bar, huge difference and you feel it, with kickdown I've seen it go to around 1.3 to 1.4 bar and then it goes back down to 1.0 to 1.1


Makes a huge difference, economy is like 5 to 10 % better when you drive eco, in sport, don't bother it's really bad, about 10 to 11 l/100km, but that's heavy foot.on the track I finished 80% of my full fuel tank on a 60km track with a average of 20/per 100km, but more air , more fuel.


It's a great choice, don't bother with the chip boxes, get a tune instead.

Nice!

I swear VW tuned these engines to fit a bracket until they released the 10.tsi. They can do more than stock easily.

My car is still under warranty (38,000km on it), so I was looking at the JB4 piggyback setup just to avoid any warranty issues should there be any. But I'm getting closer to throwing caution to the wind.

Your DSG might need a tune to account for the changes. A colleague did Revo on his 2.0t Audi and had to still get the DSG sorted to get it shifting at the right points.

I liked the fuel economy improvement you mention. I average about 6.5 per 100 on the highway, but the thing averages 9+ in city.

Report back on what it's like after the service. I might actually just go ahead and do my air filter as seems to still be the original item. Apparently I don't need it changed until 50,000km. Very hard to believe as I'm used to swapping filters every time I serviced my MK1.

[Tex]

I have a Pipercross Venom cold air intake, after testing, stock intake made more power every time, not sure why, I tried different methods and tried the traditional come filter but the OEM set up for me was best, going to just sell the Pipercross.

Check with VW, if you know someone there you could still get a way with a tune if you make a friend at VW or if someone will let you.


No DSG tune, Revo and apr said they dont have a tune for my gearbox and they won't get one either because it's dry it is more risky, a company in NL does the tune for 300 to 400€ I think, not worth it for me as it's just going to put more strain on the gearbox , because those tunes raise the nm limit and improve shifting speed , on a new car I would but not on a 5 year old one.


Your economy sounds about right to me, people are getting better figures but for me I'm getting the same figures as you, except highways on stock I was getting 6.2 to 6.5 and town I would get 9.5 to 10 l per 100km

And in today's news...



I have something weird going on with the bearings or brakes, but that needs a new topic.

I'll make friends with the local dealer and see what they have to say about doing a tune. I guess I'll see what they have to say next service when they see the sub in the boot. I wired that thing right into the fuse box. If they're uppity about that then there's no chance of doing a tune yet.

[Tex]

Some dealers issue warranty according to parts, for example having a sub on the fuse box, if something breaks and they can trace it to the sub then they won't pay, if it's not then they can fix it.

With a sub I'd recommend getting a separate fuse and wire it to the power terminal on the battery directly.


With regards to the economy, how many kilometers did you travel and was it traffic?
