Which gearbox?

I fear this thread is being hijacked - should we start another?

My tyres (195/60R15's) mean the speedo is accurate instead of overreading by about 3% however now the odometer and mpg readings are about 3% low...

I'm intruiged about the torque curve, all I have done to my ecu map so far is remove the egr and now advanced the timing (SOI) a few degrees at engine temps over 50 deg C and between 1600 and 2600 rpm - I'm being deliberately conservative to avoid causing any damage. So far no changes to fuelling or boost! Fuel consumption improved about 10% under all conditions doing this.

Are you aware of any downloadable standard 1.2tdi maps to compare? It'd be fun to emulate the 1.2 map for the 1.4 but then keep at least standard power above 2500 rpm so performance is there too!

If anyone else likes playing with these I'm happy to post my standard and modified maps (1.4tdi 90) for others to use.
 
Hello

I think, that there can be a problem with different gearshaft/propshaft. see the images, from the ETKA with different gearboxcodes

I have read your report with great interest and I want to congratulate you on how clearly you have presented all the data! I will now anticipate a rush amongst A2OC members for the JDD gearbox! LOL! I am tempted, myself ..... but I do have a fair number of lanes to negotiate, at speeds of 40-50 mph ..... Very little "City/Town" use, and usually onto fast dual-carriageway (A55) after a few Km. What do you think, Simon! Well done, again!

Rab,

Have you had either your Lupo or A2 1.2 remapped?
I would be quite interested on account of all the steep hills where I am but wonder how well it goes with the 1.2tdi.
Also the superchips curve is presumably wrong as the car is 61hp not 69hp?

John,

No remap.

Yes, good point. It's the only one I could find. I'm not sure how long an 085 gearbox would last with 90ps!

RAB
 
I think the gearbox should be ok? I thought that as long you were in eco mode it would give you proportionately the same kind of power and delivery as non eco-mode on a standard 1.2?
I guess if a remap kept the revs lower and stopped running into the red zone when accelerating on hills and so on it may possibly be softer on the gearbox?

Is there any difference in durability between the FLE or DSK geared 1.2's?

John
 
So the consensus seems to be that remapping a 1.2 would be a bad idea?
The eco map does not seem to respond that differently to normal mode (of the 1.2) in terms how it responds.
I think the key thing is the way it disengages the clutch and lets the car roll well.

The curve is also incorrect for torque as well. It should be 140Nm not 170. However maximum torque is between 1800 and 2400rp, which is correct so the curve should be OK apart from the scaling.

I'm sure that a 50% increase in power/torque would have some detrimental effect on the gearbox. If you need more power occasionally, just switch eco mode off? I'm sure if VW/Audi could have got more economy from the engine (without compromising reliability) without having to resort to building the Lupo 3L using only 20% of the parts of 'standard' Lupo, they would have done so. Note quite true for the A2 but it is the same engine.

You can't run into the red zone can you, even in tiptronic mode it changes up automatically, or should do?

While the ratios of the FLE and DSK boxes are the same, there are different internal parts. They look to be interchangeable as the cases are common. The DSK was only used for the first month of A2 1.2 production and for the Lupo 3L until 2003. Hopefully the FLE is more reliable!

On steep hills with a fully loaded car some extra power would be nice.
I would never consider 90hp remap as the brakes are not made for it. But for example a remap to 70-75hp should not be too detrimental especially once cruise control is fitted? It would be nice to have a little bit more reserve just in case.
Errm... Sometimes the system goes into red and then resettles. This is only the case on steep hills on ice and such. Sometimes the roads here fall outside of the car's logic and so it tends to over compensate. As for Tiptronic mode, it changes down automatically but not up? I have never seen it go up a gear and I can not imagine that it should as it would be dangerous on hills for example.
Ok mine has an FLE. I just was not sure what differences there were if any.
The 1.2 certainly feels more powerful than the Peugeot 208 I was driving a while back. The A2 would take some hills in 3rd that the 208 struggled with in 2nd.

John
 
Changing up on a hill in tiptronic mode should be no more dangerous than in auto mode, indeed it should be less so. It definitely does change up - no need to test! Generally I only use tiptronic when overtaking.

RAB
 
Really? I can not remember it changing up automatically. For example when coming off a steep hill with the Tiptronic mode and 2nd gear it will not go up to third. You get to 35km and hit the wall! When doing this the noise and lack of acceleration reminds you to switch back into automatic mode (if you are ever forgetful!). I was thinking of the Tiptronic automatically turning up as a being a problem or danger on long downhills where without sticking in gear you cook the brakes.
 
Maybe it's at the end of the red zone! It happened to me once and that was in the Lupo. Despite costing half what the A2 did, the Lupo is much quieter, something to do with steel vs. aluminium. You'd be deafened before you got to the same position in the A2! I cannot imagine that the logic is any different for the A2.

We're getting a bit off-topic here!

Would be loverly to see some maps from a tweaked 1.2TDI!
Maybe some pictures of how it looks with the EGR removed?

Been thinking about remapping my loverly 1.2, though knowing what the FLE gearbox is rated for torque wise would comfort me.

Hi guys,

I'm sorry to bump an old thread...

But at the start some of you was considering the EXB box. I currently have one but wish to install the longer 5th ratio. I don't know if the EWQ is the same internally as the EXB? Can anyone help?

Thanks

Hi Dblock,

I've seen your other thread. I've got various graphs showing the differences between the EXB and EWQ gearboxes and will upload them as soon as I get the chance, along with some advice about longer 5th ratios that'd suit your car. Apologies the the delay.

Cheers,

Tom
