Superchips - Superchips optimise the performance of your car, helping to maximise your driving pleasure.

Interesting last time I looked the 3.0L wasn't htere but the there was a separate choice for the 2.7L D4. Maybe the same hand held module does both. You will need to check.

Powrr curve, 2.7L:

Power curve 3.0L (needs to be done by the dealer):

Interesting data on those Dyno plots when you compare them with the original Factory specs.! Only got 638nm max , not quite the 750-800 some may think possible
Blame it all on the Parasitics !!!

Excuse what may be a silly question, as I do not know about such things. On a normal rolling road, the statistics are taken from the wheels. I thought that to get engine stats eg kw at the flywheel a special dyno is used where the engine itself is mounted in the dyno - so were the above figures taken from rolling road figures and then calculations done or were engines removed from cars and put on an engine dyno.

Sorry if this is a silly question - as I said I do not know about these things.

I'm going on the dyno on Monday, so i will ask the question Garry.

Should be interesting results!

Every chips/ tune AND Car will be different, just look at Steinbaurer example.

Don't read to much into the numbers, any one that has had a custom tune or even a plug in tune will say it feels better in smooth power and 'perhaps' fuel economy.

Saying that, I moved around my calendar and booked in the dyno for Monday just for you ... lets hope the results aren't in my head...

Thats good Dorko , do you know the Brand of Rolling road he uses .?
Make sure he plots RPM against HP , as road speed will be useless . I seriously doubt whether they will be able to produce any meaningful Torque curve due to the mass of variables .At least find out what the "Ramp rate" was . (Allowed acceleration in RPM/Second) Make sure you record what gear , what range , Tyre pressures , Standard and corrected Air ,Converter locked ,and if he make any allowance for both engine and / or drivetrain Parasitics. If only yours was a manual , it would be so much more accurate .
This is why GarryCol's question is so pertinent !! Engine Dyno or rolling road dyno ?
PS , Steinbauers graph for torque on the 3 Litre is purely a fudged mockup . a schoolkid can see that they have just added a standard deviation to the original torque curve , a well educated guess !!
(Whats 120% of 180 KW ?, well its 216 KW ! Whats 120% of 600NM ? , well its 720NM) Now aint that a coincidence , Power and torque improves at exactly the same rate !!!! Yeah ? BS !!!

My new maps seem to work well. done roughly 100km now so i guess its adapting. Definetly more power and torque, and barely a hint of fuel smoke on full blooded launch off the mark

Hey there.

In the UK on dyno's they calculate a flywheel figure off a calcualted dyno loss figure. Im not sure how they come to the % loss figure thou.

It would be good if they used rear wheel figures like the rest of the world thou
