Launch control for Motronic

[Acidburn]

20 mins of fun with captain dremel to remove the extra material ?

Recruit Madwolf?

beat me to it

Paul, do you have a picture of the pot control so I can have a think of the best location on my urq.

Will post a pic of my knob soon.

oo-er matron !

pmsl - cheers paul

Agreed on the button.
Well, this is better than nothing - also, it managed to build 0.2 bar boost on that car, and it's running a k26/k27 hybrid.

Cannibalise an iPhone 4 and use the antennae to build a palm sweat detector for the steering wheel.

Make use of antenna-gate

I am going to show you my knob this weekend.
Or at least as soon as the bunch of electronics stuff I ordered arrives.

[Acidburn]

cheers, hmmm might be able to use that on the urq inside a spare headlight dimmer switch casing

Knob did not arrive yet

The ones I ordered are soft-touch black and the stripe is red.
Should fit well with our cars.

Does not really matter where to fit it. It has a nut to tighten it down to any panel, just need a small hole.

To prove that I think a centre console switch is a bit unsubtle - I did it on mine. See attached pic.

I definitely think that a location near the handbrake is better as its closer to the driver and much less visible. That and there is a whole world of dremel action required to modify a B3/B4 switch blank.

I have ~1m cable runs made up already - they are plenty long enough for numerous locations of user preference.

PS - I just added that 'g' legend on for fun on the computer... in case anyone wondered.

I quite like the way it looks there

Anyway, glad to hear it goes to 11. I had to take an amp back when I realised it only went to 10.

My new knobs have finally arrived.
Lots of soldering to do now, but I will surely be able to demonstrate you the functions of my knob until the end of the week.

Now in all seriousness - I have enough for ten kits.
I guess 2m of cable should be enough per kit.

Basically you will send your ECU to Paul or myself (whichever is closer), and then you will get back an ECU that has a 3.5mm socket poking out.
You will also get a 2 metre cord with a 3.5mm plug on one end and the knob on the other, so you'll be able to mount the knob anywhere you wish.
The pots are panel mount and include mounting nuts, so it is possible to make a small hole pretty much anywhere in the trim and fit it there.

In the future, it'll be possible to get flat foot shifting as an upgrade, and that'll likely be DIY, since all the soldering work is already done in the ECU.

Serious question, what's the benefit w/o anti-lag? I can infinitely adjust the throttle with my foot w/o this.

[gedu]

The difference is WOT throttle body with this and not that much opened without it. Difference being more boost built up on the line.

I have written this many times in this thread:
It builds 0.7 bar boost on my car, so it does have an antilag function as well.

Good luck building any boost while playing with your throttle, for the reason gadu stated above.

[Ross]

I think what he's getting at, it what is the difference between holding 5,000rpm with your foot vs with this function? If I hold 5,000 rpm in my car there's pretty much zero boost so I assume something is different, 0.7bar is quite alot!
