Do you need injections if you to go to Scotland?

As Wrinx said, I took the chip from one 1997 car and transfered it to another 1997 car, but they had different ECU's, so it wasn't making any difference. It runs better now, but I can't find where I have put my graph!!!

I used to race a Lotus Sunbeam and used rolling roads to fine tune the set up. The power figures are really only meaningfull when comparing before and after. Even then it should be back to back on the same day since atmospheric pressure can affect readings up or down (colder damper days will show more power due to the greater density of incoming charge). Also different rolling roads tend to give different readings so the same car with the same set up on the same day can read better or worse figures dependant on the rolling road. There are many other factors like higher tyre pressures on the driven wheels will tend to give better readings, however I hope the point is made.

The temperature and pressure issue is taken care of by the fact that all the plots are corrected to DIN70020. DIN 70020 corrects the temperature and pressure to 20C and 1013mb, so the plots can be directly compared.

Obviously, there are other factors that can affect the dyno output, but at the end of the day you are trying to compare cars (inc. drivetrain, tyres etc), not just their engines.

Hi guys
I had my (now sold) 2,0 16V '96 fitted with a map able Unichip last year at around 79k miles. Below are the rolling road test figures taken before and after the mapping - taken on a cool and damp morning.

1500 29,9 33,1
2000 41,7 47,6
2500 57,4 68,9
3000 72,2 85,5
3500 87,9 103
4000 109,9 119,3
4500 122,9 136,1
5000 135 149,6
5500 145,7 162,5
6000 156,6 175,8
6500 163 185,8
7000 154,5 182,1

1500 142 157,2
2000 148,5 169,5
2500 163,5 196,3
3000 171,4 203
3500 178,9 209,6
4000 195,7 212,4
4500 194,5 215,4
5000 192,3 213,1
5500 188,7 210,5
6000 185,9 208,7
6500 178,6 203,6
7000 157,2 185,3

My coal for fitting the Unichip was to gain more Torque a low revs - which I did with an increase btw 15-20% btw 2000 - 3000 RPM. A side bonus was to see that I had 163 HP standard and 186 HP chipped on tab(on a cool day, in more than one sence).
The Unichip is a bit on the expensive side at 350 incl. the mapping. I have not (yet) fitted on to my 156 2,0 as the difference in engine mapping gives a marked increase in torque already at2500 RPM (compared to the 155 at 3700).

Impressive results was that just from the chip or are there other mods as well?

Technology is a wonderful thing, it is not unknown for some rolling roads to read higher than others through incorrect calibration. I remember a report in a motoring journal a while back suggesting that a particular road was calibrated to make the tuning products on sale appear better than they really were. Surely not!
