#1: Just gained 10% more throttle on my 180 Author: mattymj, Location: NorfolkPosted: Fri Sep 19, 2014 8:42 am ---- After looking through my PP2000 i noticed my throttle would only goto 90% when pushed to the floor
Tracked the problem to the accelerator pedal.
Tried 2 option which both worked.
1. Remove the accelerator pedal and place two washers on each thread.
2. Remove the accelerator stop plug
Hey presto
Have yet to drive it as was in a rush.....
Can anyone see any problems with this gain?

#3: Re: Just gained 10% more throttle on my 180 Author: mattymj, Location: NorfolkPosted: Fri Sep 19, 2014 1:51 pm ---- I thought 100% would equal more performance than 90% more air more fuel etc
#4: Re: Just gained 10% more throttle on my 180 Author: Edward, Location: In the garagePosted: Fri Sep 19, 2014 2:37 pm ---- That's if the throttle body at 90% is a restriction. The engine might be consuming as much air as it can even at 90% throttle.
#5: Re: Just gained 10% more throttle on my 180 Author: mattymj, Location: NorfolkPosted: Fri Sep 19, 2014 3:48 pm ---- I guess it could be but every little helps. Would the ecu alter the fuelling between the % difference?
#6: Re: Just gained 10% more throttle on my 180 Author: Harry, Location: StaffordPosted: Sat Sep 20, 2014 7:44 am ---- Yes it would, I don't see any negative issues occurring.
#7: Re: Just gained 10% more throttle on my 180 Author: mattymj, Location: NorfolkPosted: Sat Sep 20, 2014 10:09 am ---- Well I have popped the grommet back in the carpet and the pedal is registering 90% again when floored, I have been looking in my PP2000 menus to recalibrate the system but can't see an option, I tried resetting the auto adaptives but at no point did it say to floor the accelerator!!
Is there something I am missing as there are hundreds of menus on the program
Any help appreciated
Thanks

#9: Re: Just gained 10% more throttle on my 180 Author: Maqer, Posted: Tue Sep 23, 2014 8:17 pm ---- Mine shows 94% or 95% but I'm getting sub 7's 0-62 acceleration so I don't think it matters much. I'm not sure that it's accurate representation of the gas pedal position. Maybe a movement range that the pedal has? But still at the whatever % you get the ecu is giving full acceleration? It's pretty smart and calibrates the throttle butterfly and pedal.
You can do the calibrations manually too, check the how-tos.
#10: Re: Just gained 10% more throttle on my 180 Author: gpvecchi, Location: ItalyPosted: Wed Sep 24, 2014 2:45 pm ---- You can recalibrate butterfly inside ECU parameters with PP2000; but I think this is useless, as throttle just follows 10% steps, you'll see 90% but it could be 99%; when calibrating butterfly you have to set the pedal from full lift off to full down, and this is paired with butterfly. So, if butterfly opens 100% (you can see it with key on and engine off), everything is ok.
