Early Morning Mapping

[humpy]

It’s 1:15am and as I write this I am having the car (2.5) mapped. The base line we started with was 285bhp. New maps were loaded and the first run took it to 303bhp. The boost controller was then connected and it made 320bhp. Trevor is still tinkering with it but it all looks good so far.

The boost control problem I had was because the car had a 'mechanical' map loaded which didn’t restrict the boost pressure and caused bad over boosting. The new map takes it to 0.9bar I think.

Just done another run at 330bhp – that’s a 45bhp increase from where we started from. Needless to say I am quite a happy chap

Will post scans of the plots as soon as poss.





Looking forward to the drive home – and bed

Enjoyed the drive home - what a difference! Thanks to Trevor & Steve

As Trevor said - "you are leaving with more at the wheels than you came in with at the crank".

edited to get the name right - sorry Steve

considering his current workload, Trevors committement to the Noble fraternity is amazing

[YellowShed]

Thanks, guys. Always nice to receive positive comments back. Yes, this week has been even more stupid workwise than I thought possible, but mapping Nobles is fun, and I have a good laugh with Steve down there....

Madmacmcmad noticed the changes to his car too. Shame he didn't have the 6-speed otherwise we could have left the much higher...

I'll certainly be booking up when time permits.

Trevor, I did offer to drive back as Humpy looked tired, but I quickly retracted by the way he looked at me

Spot on Paul, Trevor and Steve

Paul, enjoy the new power!

[C&C]

Well done Trevor - again!

Paul - you must be very well pleased with those results - excellent.

[saucyboy]

That's fantastic mate!!

Your fav wet runs should be even more fun

think we finished at about 2:40am

[humpy]

Having spent more time in the car, there is a staggering difference. Not suprising really with an extra 55bhp and 336lbft at 4300rpm

Here's the dyno plot:



Stop yawning Adrian...

[Mr Noble]

Nice.

I take it you have the OEM exhaust. If you change it, the blue line will hit the top and stay there till 6000 rpm. Both lines will also move up a fem mm

Nice work! Should be getting my baby back today! [fingerscrossed]

[R4MON]

Think I need to remove my passenger seat, stereo, wipers, lights and spend more time at the gym. I can't have Humpys 2.5 embarassing my 3R....

Top job. Looks like an original 2.5l exhaust that exits under the floorplan? I the sound that makes on full chat, sounds like a jet fighter

You jest mate, but a few quid spent on lightening will make one hell of a difference !

Go 2.5's !
