Correct steps to dyno a 335i steptronic.

CaptOz · 07-20-2007, 06:36 PM

Hi guys. I am having my car dyno’d next week to see what the rear wheels are putting out with the PROcede. After reading some earlier posts, I believe the correct method is the following:

Ensure the DSC is fully off (held for 5 seconds).
Move the auto transmission selector to sport mode.
Accelerate gently using the paddles to reach 4th gear.
Accelerate hard but do not let the accelerator pedal reach as far as the “kickdown” click.
Let the engine rev up to redline.
Drink a glass of champagne to celebrate the fantastic results.

Does this method seem correct to you guys?

Cheers.

Yup.

Div4our · 07-20-2007, 08:57 PM

exactly correct bro.
make sure you load up the graphs.

normtrum · 07-20-2007, 09:10 PM

Perfect. Just make sure that when you're in 4th gear you start your run at about 2000 rpm's. The tech that did mine a few months ago kept trying to start at about 4000 rpm's. Obviously it kept getting screwed up, until I stepped in and made him do it right (they wouldn't let me do it for insurance reasons).

Edit: I forgot, after you start your run, you don't need to paddle shift, let the car do it.

Sounds good... Let 'er roll

hl0m4n · 07-20-2007, 09:48 PM

so after reaching redline move shifter back to normal drive and slow down?

Never put on the brakes on a dyno, unless you want to buy a new set of pads.

Just let the car do the work. Once you hit redline, it will automatically down shift. At that point, just take your foot off the gas pedal and you're done.

You need to use the paddles to get the car in manual mode. That way you can give it full throttle at 2,000 RPM in 4th gear without a downshift.

hl0m4n · 07-21-2007, 01:10 PM

so 2k rpm in 4th gear, redline let go of gas and let car roll to a stop in manal mode as the car will auto downshift? then do next dyno run, etc?

ya, looks good. Just so you know, I didn't have a clue at first, I had one dyno screw up (I've had 3 so far) so I called shiv, who has litterally done hundreds of these, and got the low down from him.

why not hit the kickdown click

surely all operators would know how to run up an auto

it'll cause the car to downshift.

Ha ha, I wonder if you can get a DUI while on the dyno.

hl0m4n · 07-21-2007, 03:00 PM

the most accurate dyno is a dyno jet? when printing out results i just tell the guy give me corrected numbers?

if you end up ramming the walls!

hl0m4n · 08-10-2007, 02:11 AM

hey what are all the wires that the guys at the shop put into your car on a dynojet?

when doing the dyno do you guys ask for corrected numbers? dynojet is most accurate?

scalbert · 08-10-2007, 08:18 AM

Question, where has everyone picked up a tach signal? I would assume one of the coil packs would suffice. But what is the easiest method to get to one?

ni66ale · 08-10-2007, 02:04 PM

what about dyno dynamics is that a good dyno?

Div4our · 08-10-2007, 02:19 PM

There's more variables than just what dyno you use people. What temperature it is, if the dyno is calibrated correctly, etc.
Mustang dyno's tend to read high from what I've heard though.
