it was just my luck that leighton's normal dyno was closed when i went for my remap...it would have been a fair comparison to the first set of figures i attained in october...

Well its a good sign that whats showing on the graph is correct it would be nice to have the figures to do justice to the condition and mods ive got on my engine

What is strange is that i dont remember him going to the back of the car to strap it down...he seemed to concentrate all his efforts on the nsf wheel area...my friend steve came with me and if he is reading this id appreciate confirmation of this...i may have missed other stuff... http://img.photobucket.com/albums/v459/monktoncombe/007.jpg

So just a strap somewhere at the NSF is sufficient?
Also is it normal to have the ABS light on afterwards? It turned off when we started driving out of the garage

No and Maybe.
Depends what perameters bring on the ABS light, many will come on with the fronts doing 100 and the rears 0 but will need a cycle to reset.
I.E ford require an ignition cycle and over 7 mph speed on all 4 wheels. I used to turn on the ABS light all the time on two poster ramps.
But i DON'T know fiats ABS system, so may not be similar.

To me the data and results looks genunine. I think people are looking to pick holes because it didn't make par with what it "should have made".

Surely you should get the same or even better figures with a standard set up though after a flea map ?

Last time I made 284bhp and 293lb/ft on one run and 279bhp and 279lb/ft on the next run. This time I have a better fuel regulator and a sports cat...bit more boost and ignition advance...I expected to make at least the same again!

it looks like a dodgy dyno theres a massive difference between the whp and flywheel power 60hp on a fwd car is far to much
my r32 gtr had a 60hp difference between 4whp and flywheel hp looking at the whp your car should have about 230hp 240hp at the flywheel
did they change the fueling? it might be running far to rich now causing the power loss does the car feel any slower? with the mods your cars got it should be 250+ whp

does the car feel faster now, if it does I wouldnt worry to much about the dyno figures
of course if you can get the car on the same dyno then regardless of whether it is optimistic or not you will be able to see how the changes you have made have affected the power and torque
if fleas telling you your car is faster than a stage 1 then it will be regardless of what the dyno says

I'm happy the car is running right and Leighton did a very good job it pulls well and gives me a nice surprise sometimes when I put my foot down. Everything is always as it was and was very surprised to be so disappointed yesterday I mean I need to move a few places up on leighton's league table I'm going either get down to Leighton's dyno or I'll visit 'enhanced performance' in bolney once they have installed their dyno dynamics rolling road...as I said before numbers are just numbers but just out of principle it's nice to have confirmation on paper...if you know what I mean

If it was me and the RR graphs showed those figures after all those mods..........I would still be peed off even if it felt like it could fly at Mach3 and orbit the earth.....running on orange juice

Yeah so fingers crossed. I'll be very confused if that dyno tells me that my car is making less than it did last time I was there as the car should be a bit better in every way now

Steve Indeed, most ABS lights come on after a Dyno visit, especially FWD and RWD vehicles. 60bhp coastdown loss, hmmmm lovely if you want 'pub' flywheel figures! No need to strap the rear of the Coupé down as it's FWD.

Every dyno run I've ever had has come up with the same coastdown losses. 60bhp seems about right at the rev limit, with about 45bhp at 6,000rpms.
F****** b****** thing...
