We have a dyno plot!

They still had last year's run on file so we could do some comparisons.

Outside temperature was 29 degrees C compared to 28 degrees last year, so air temps are consistent.

Shame it wasn't like today - 12 degrees and damp

So we have:

Standard map (supplied on my STS) - 165bhp at the wheels, 174lbft of torque

(10psi max boost)

Custom Code Stage 1 - 180bhp at the wheels, 207lbft of torque

(22psi max boost)

Shark Performance Stage 2 - 207bhp at the wheels, 256lbft of torque

(22psi max boost)

The second run was lower each time - so I need that FMIC in this weather

What ratio should I use to estimate flywheel bhp?

Points to note. The standard and Shark runs were with 2.5" decat downpipe, CC run was with standard downpipe and cat.

Engine mods - Carbonio CAI, APR TIP, Relocated DV, Bailey DV30.

read what i said on the other post

you have a flat spot at 3krpm try cleaning the throttle body

aslo the torque curve is really peaky what it like to drive???/

should curve much better when you have a front mount fitted and you wont get that heat soak...

is it down on power then???

same as the power it should hit the top and hold that doesnt it drops away straight away should go like the custom code 1 see how it holds

Hi Rob, not sure about the way the power and tourqe drops off at the top end. I would have thought the bhp would continue to climb more like the standard map? I imagine theh FMIC would help a bit

edit: beat me too it again Clive

:p

Add about 10% to the WHP

What does the boost curve look like in vagcom? I had a similar pattern of peaks and troughs on the first ECU Evolution map that I had, I believe it was boosting too hard (n75 duty cycle was 95-100%) they held it back a bit and is now a much smoother delivery.

According to that I have 241 bhp at the flywheel

lol never happen :giggle:

It drives fine and when I accelerate hard I don't notice that 3000RPM flat spot. Strange. Must do more driving to test

Will clean the TB when I get a chance. I've had the spare gasket for 2 years but never got around to cleaning it!

Also have a couple of bits on order

i would speak with ben about the flat spot as its only on his map curve

i would also ask if he can flattern the curve out to hold the power and torque as it drops away far to quick very very peaky map

This is interesting from VWVortex - REVO stage 2 with a similar looking power curve:

2004 1.8T

-REVO stage II

-2.5'' custom Borla TBE

-AEM dryflow filter on MAF

-Garret ATP FMIC

-Forge TIP

-Bosch 4bar FPR

-cooler spark plugs

-Lucas Octane Booster

I was told I'm running lean...more fuel and some boost tweaks and hopefully I'll get some moar hp and tq. Max boost was 22psi tapering down to 11psi at redline.

wow another shocker

The wheel horsepower on the standard map sounds high? I'm sure mine was only something like 150 which worked out as 188 at the flywheel :S <looks for RR graph>

Yes I think their dyno is a little optimistic Especially in 29 degree ambient temperatures.

There's anothet company in town who have one apparently - must find them, see what they charge.

thats another map where the tourque drops of like an Alpine Ski Jump

karlbar2k your missing the point hese are the new super doper maps now on sale

all the power at 3 to 3.2 k then you have to change gear lol

:rofl:

I know I only have a stage 1 generic map which can sometimes be flakey due to overboosting, but when I have logged the tourque/bhp at the flywheel in the past and got a good run in it is a very different chart to that.

Just used this and put in my WHP (111) and it gave me 134 at the flywheel, so that's a bit optimistic as I got 121 at the flywheel at Awesome

No-one seems to know a true multiplier. I guess it's a bit hard to work out accurately

This was a run on the original map which was boosting to high too soon causing the N75 some issues trying to regulate it hence the spikyness. Even so it would hit max tourque by 3K and only tailed off by 40 to the red line

haven't got a decent log since the reflash but it is much smoother now and not so much time spent limp :D (que the smutty comments :p)

I've been thinking about this. I can understand the point about the way the power drops off but both Ben at Shark and an independent tuner have said the same - that the k03s just can't sustain the boost to keep the peak power going. That's fine as most of the time I'm not ragging it to the red line. Plus up to 6000 RPM the Shark map is still higher power and 25% more torque than the CC map.

I did a standing start from some lights on a dual carriageway and you can feel where the power starts to tail off but it's not exactly without power! )

I'd like to get it dyno'd again since cleaning and resetting the throttle body and removing the N249. It definitely feels smoother after that.

I'm happy with the way the car drives with this map. It feels more powerful and smoother than with the CC map and has much more of a kick in the back than standard when booting it

And it's not running lean as hell

cool as long as the end customer is happy then the map is great for that person and thats how mapping should be
