EA288 2.0 TDI 184PS Development thread..

[Andrew@DTUK]

Andrew I see on the graph it has maximum power wheels / maximum power engine.
Where do VW measure the power from?

VW measure engine output when they quote 184PS/181HP/135KW, most VAG cars are a good 5 to 10% above when run in, it's like a worst case scenario figure.

So tempted but for the fact I would feel obliged to swap out my sh!tty Bridgestones or be extremely careful. The other box I trialled was amazing before I returned it for tweaks and they cut the power right out to address traction issues. This system seems to have had a lot more thought go into the mapping.

On Sharks dyno the car ran 179bhp in standard form (400 miles on the clock) then 226bhp tuned

Andrew any chance of coming up to see you in consett and taking me out in yours to see what the difference is 

That would be my pleasure, CRDT and then CRDT plus pedal box 

Id love to hear the feedback if you lads meet up. Not that i dont believe you Andrew lol

Well anyone is more than welcome to pop and see us anytime, the kettles always on

I'm just down the road in Sunderland and get my washing gear from you Andrew. what's the best day/time to come up?

How many miles were on the car at that point? Maybe the engine output is better metered by VAG than ever before, so they stop cars being overpowered? It would be interesting to get 3 or 5 GTDs or the Skoda/Audi/Seat equivalent and see what they run on the same dyno to see if we can see any variance in stock output - if they all had the same output, regardless of mileage beyond running in then it would seem that greater control is in effect. Might be a little impractical/costly to prove though. 1% off theoretical output seems pretty close to VAG's design intent.

400 at 226bhp on sharks dyno with 490nm, 2000 miles today with 232 and 500nm

A little confused here (i've been out for a few pints!).

1. Are the numbers above same conditions (same map, same dyno), but showing how much better the car is at 2000 miles on than 400?

2. Or are you showing improvements seen with a new map/tweaks to settings on existing map.

3. Or is it everything the same, but on a different dyno?

Assuming it is 1, then 179BHP to 226BHP = stock is 79.2% of boxed output.

Assuming same potential increase, it would suggest that the stock car with an extra 1600 miles on is putting out 183.7BHP, which is good news for everyone.

If it's 2, then your tweaks have yielded a 2.7% improvement in output.

Same car, same maps/box, different dyno

Is this now £309 with discount now?! Can't find alternative on your website..

Found it, was looking at stage 1, not 2!

The point is that the results from different dynos will differ...

In fact even results from the same dyno will differ on different days (dependent on conditions)...

So, dyno results should only ever be used for comparison. So, you go for a day at the dyno, you run the standard car, log the results, make some changes, log the results and compare... and so on.

The next time you go, you should make a run as a base and work from there.

The absolute numbers generated are for pointless willy waving... the thing you're really after is to verify  any improvements made due to changes...

exactly, the point of posting the graphs was to show that the results are consistent between 2 different dyno's
