Engine mods

[HighFlyingBird]

All modifications to the car have potential to affect the warranty (including things like Carista / OBD11/ VCDS) because its not how the car rolled of the production line.

Why do you need a dsg map in simple terms you have changed the power output from the engine so the gearbox needs to be changed to support that. Plus the mappers will add in extra safty features and extra settings that the stock car did not come with.

Example on a stage one map (DSG)

• Launch Control variable RPM
• At 0-30% throttle launch RPM is 2500
• At 45-60% throttle launch RPM is 3000
• At 70% throttle launch RPM is 3250
• At 85-100% throttle launch RPM is 3500
• In Launch Control Mode 6300rpm rev limit
• In Drive and Sports Mode gear shifts at 6500rpm
• In Manual Mode gear shifts 6600rpm
• In Drive and Eco mode at low RPM, 2nd gear is held unless you come to a stop
• Removed 'Kickdown' in Manual mode
• Optimised shift speeds

But you can carry on with modified engine and stock gearbox.

For me the point of modding is getting the perfect car for ME which may not be what you want.
Car manufactures build cars to sell to the majority and its very rare to find the perfect car off the shelf

Makes sense that the gearbox should be mapped to cope with the extra power, my car has the 7 speed DSG though which doesn't have launch control so none of that would work for me, I'd only really benefit from the RPM changes. I don't plan on mapping the car until the warranty is out anyway, so another 4 years to go.

Sorry my post was me as usual only thinking about my Cupra.

If you look at the Revo site they appear to only do the DSG map For the 1.8 and 2.0 petrol cars,
Other mapping companies however may offer this service to the DQ200 Box.

I don't know why but can only presume that is because these engines can produce a lot more power with a map and need the gearbox upgrades to match it well.

As I understand it from doing some reading, the diesels, in particular, make enough torque as standard that they're close to the limit of the standard DSG programming, a remap will boost it plenty but the box will try and reign it in. Get the box mapped and it'll let you have all the torque, all the time.

I'm going to book my 184 in for both an engine and DSG map as my local tuner does the DSG map cheaper of it's done together.

Might not be as commonly available as maps for the 1.8 and 2.0 cars because the 1.4s and below don't make enough power to push the gearbox close to it's limits even when the engines are mapped. I'm not a mechanic or anything though so who knows.

Also the 7 speed dq200 was not designed to handle bigger power, it had a troubled start in life but they seem to have fixed it now.

 

[Dominic]

He'd have the 6 speed DQ250 though wouldn't he?

As I understand the 7 speed DQ200 is a dry clutch box and can't handle too much power, is fitted to the lower powered cars.

Seems like it's more for emissions/economy than the 6 speed one is

Nope it's the 7-speed box in the 1.4 ACT engines, 150bhp doesn't seem too underpowered compared to the 1.2s and new 1.0s though. From what I can gather VAG cars with DSG boxes come in 3 versions, wet clutch 6-speed, dry clutch 6-speed and dry clutch 7-speed.

 

[Dominic]

There's too many bloody variants of these gearboxes.

I thought for the normal range cars it was:
6spd Wet Clutch - High Torque Capacity
7spd Dry Clutch - Low Torque and High Toque variants.


How can you tell which cars have which gearboxes? I thought the DQ200 7 speed was fitted to the 1.8 and under petrols since they make maximum of 250nm.

DQ200 Is the gearbox used on the smaller engined cars.

DQ250 Is what the Pre Facelift and Facelift cars (bigger engines) had before the WLTP Changes.

Cant recall which version the new WLTP (Bigger Engines) have but its a 7 speed version.

I think we have the DQ381 fitted in the WLTP cars. The 7 speed wet clutch DSG, the DQ500s little brother.

Mine definitely has the DQ200, does anyone know what changed with the DQ200E? If the DQ200 had a troubled start is the E the one with all the revisions fitted?

 

[Dominic]

Might be the one fitted to the GTE?

Forgot the GTE was a thing, so might be for that then
