Title: How to Decrease HP output? ME7.1.1 R32 Post by: hummel on December 21, 2018, 12:06:15 PM Hi Gents,
So I got my Car running, and I tried to get it through mot, but i cannot get it approved with the original 250 Hp, the car can only be approved with 220 Hp. So how is the best way to decrease the power ? It is a NA engine so lowering boost is not possible :D But with my limited knowledge to the ECU I can think of following: Lowering NMAX - FEB82 - i believe it is on 6500RPM at the moment, how much, any guidelines? Changing Driver Wish Map - E8636 - How? How much, any guidelines? Is there any other/better way to decrease the power so my car can be approved. Title: Re: How to Decrease HP output?

That is the only question that matters. Without an answer to that, there is no way to solve the problem. Title: Re: How to Decrease HP output?

Fuel has to be adjusted for that aswell , no ? Title: Re: How to Decrease HP output? ME7.1.1 R32 Post by: sonique on December 21, 2018, 03:32:52 PM not need
lower air lower load etc .. Title: Re: How to Decrease HP output? ME7.1.1 R32 Post by: nyet on December 21, 2018, 06:34:21 PM if he can get away with it the easiest would be to lower the rev limit

The Car would be testet on a dyno to prove that the car has the legal amount of power. There is no rev counter in the, and they will not put a tester on to monitor anything. they will however test emissions, but that is not a concern since the car is old it is allowed to pollute quite a lot. So ? Revs to 6000, and KFWDKSMX max 70 % ? then I sure will be under 220hp ? Thanks Title: Re: How to Decrease HP output?

plz report before test dyno make log original maf g/sec and 70% tp Title: Re: How to Decrease HP output? ME7.1.1 R32 Post by: nyet on December 22, 2018, 09:34:12 AM You can use ecuxplot hp calc to estimate
But dynos are all different so you should use a stock car with a known output on that dyno as a reference. Just guessing makes zero sense, this is pretty basic stuff. |
