1.4 APR Chip - First Impressions

[POLARBEAR666]

How are the tunes going guys.... does car feel like its getting faster now that computer has adapted a bit?

My car is flying atm in the cold weather and without a supercharger cover I am getting only 3-5 degrees difference between ambient and intake air temps hehe. My traction light at light throttle is flashing all the time.

I just read this whole thread. Part of me laments the fact we weren't patient enough to hold out another 3 months for the GT TSI we ordered. The GTI is good, but the TSI is a better day to day proposition becasue it is less jiggly and the power is available immediately. Bugger hey, and congrats on your choice to upgrade.

[golfyvic]

I got the TSI for the exact same reason!

Yay, someone else who can answer the questions as well

The consumption varies alot on how you drive it.... If you drive normally I have found it to be pretty much the same but if you give it some it will chew more than giving it some on the stock chip.... Hope that helps answering the consumption question....

I'll have the comparison up and running on YouTube Monday arvo.....

No worries.... got the car booked in for the ecu flash sat morning. Gonna be nice and cold too so I'll probably get home in record time, (I'll try not to speed)

[BarneyBoy]

all i can say is ...... VdUb !!
1.4 tsi is an amazing engine imo.. why can't they just have a 2.0 twincharger version on the GTI

Apparently over 1.8 litres the reciprocating masses and internal friction deliver diminishing returns. They chose 1.4 litres as many European countries offer significant tax advantages for sub 1.4 engines. But I agree, it's too bad.

I went with the REVO tune on my MK4 Golf GTI. Certainly sounds like a lot of fun can be had with the 1.4.

Most of you may have seen this but as on topic, here is a link to the process of chipping my VW with dyno runs etc.

Doesn't the new S3 7speed DSG handle 350Nm?

Is this the same box as the GT and Jetta box?

Guy do you know anything to shed light on this.

I would be alot happier doing a flash on Jetta TSI
knowing that it can take 350Nm.

(BTW I have a Jetta TSI loan car while my Passat in
in for service. All I can say is what a sweet engine)

[Guy_H]

Torque control is not an issue on these.

A lot of work has been done on the factory symbiotic mapping between the engine & gearbox torque control.

You would be pretty comfortable to add over 40% to the 350nm figure for a destructive level.

No. It's a completely different gearbox designed for AWD applications that's rated for 550nm.

So the gearbox isn't limiting thetorque from the chip to 350 mm then?

[Guy_H]

It does, but it's not that simple - there are hundreds of intertwined tables.

You will see (from dyno's that can measure torque & drivetrain loss) that a DSG in most cases will transmit almost exactly the same level of torque as a manual car. There are exceptions, but its nothing to worry about.

The Nurburgring Scirocco's ran DSG outputs & APR hardware - on DSG gearboxes in race conditions for 24 hours (and they ran for weeks on engine / drivetrain dynos before that). - Stock DSG mind you!

So here it is:

converted GTI (stock is) 197HP and weighs 2948 Lbs
converted TSI (chipped) 202HP and weighs 2882 Lbs

Now for the calculator:

GTI (stock) 1/4 mile in 14.35 secs @ 94.95 miles an hour (152.8 Km/h)
TSI (chipped) 1/4 mile in 14.13 secs @ 96.48 miles an hour (155.43 Km/h)

Theoretically the chipped TSI wins on paper....... BUT ONLY JUST!!!!

Using the calculator i've got:
GTi(stock) 1/4mile is 14.98@94.1mph
TSi (chipped) 1/4 mile is 14.78 @ 95.5mph

Just as another point of reference
Checking up round the forum seems the first set of results is closer.

Can you send a link to a calculator?

So, um, what's the point of all these chips offering torque of greater than 350nm if the DSG can't use it?

Forgive my ignorance, I'm just trying to understand how it all works.

No. It's a completely different gearbox designed for AWD applications that's rated for 550nm.

Maverick since when did the S3 have a longitudinal engine install?
You are wrong it seems. This isn't the gear box for the S3.
Thanks for the links BTW.

I would assume that the S3 7 speed is a totally different beast.
A variation on the transverse box to include the haldex?

Anyone know about this?
