"Davy, how much extra are your insurance company charging you now that
you have told them about your 48 bhp and 64 lbs/ft of torque."
Eh £5.60 plus vat.
You tell me what ins co would be able to check or do check if the ecu map has been changed. Tho with a box its a visible item.
Paul maybe todays cars are ran lean so that the emissions are low for green issues and low tax which is a good selling point in todays GREEN world. So these "boxes" change the air/fuel mix to achieve the extra power by increasing the amount of fuel going in but have it set at a good ratio to obtain good results. Now if you have too much fuel to air then there would be a noticeable change in mpg and worse case black smoke emitting from your pipe.
This did NOT happen to me with the Rio so the box worked in increasing power and not increasing fuel consumption. There was no way the Rio was over fuelling.
As you tuned and raced petrol cars you will know that if an engine is running air/fuel ratio above 14 there will be a drop in power as its far too lean. As you know the ideal fuel ratio nowadays is between 12.5 and 13.5 for good performance and good consumption.
But Paul you didn't race diesels according to your previous posts.
These boxes work best with diesels with turbos and same with remapps.
So what is it I am feeling when I had the Rio ? is the wind resistance lessening or is there a big magnet in front of me.
Look Paul these "boxes" work and until you try one then you cannot argue. How can you disagree with the people who sell them and people who have used them and know they work.
Also how do you know that a remap does not let more air in along with more fuel to give that extra power. Can you honestly stand up and say it does not. The air venturi plate or regulator flap as its called on my Leon is controlled by the ECU so it can alter the amount of air to fuel plus what the turbo puts out is also controlled by the ecu so that will be adjusted to go with the changed incoming charge of air/fuel.
Now on my Hayabusa Bike I got that remapped the other week just to make sure fuelling was correct throughout the rev range and I watched the guy doing it all on the dyno. He must have done more than 20 runs and got the fuelling correct as it was running lean between 3k and 6k revs. Power increased by 10hp in that range. With the remap I saw the tuner change the values of the injectors and alter the timing. He also took out top speed restriction as now it will do 195mph and there was restrictions in power on 1st 2nd and 3rd gears so that it would not lift the front wheel too much.
Aww sh*t I've missed the cut off point to buy a ticket for the Euro millions tonight
If I won Paul I would buy you diesel car and throw in a tuning box for you to try.
