If you need proof then come down to the next rolling road day at Red Dot. You say your car has been mapped by Angel? Then get it on the rolling road and see how you feel with your results?
1000 mile round trip? nah
We don't slate angel for the sake of it. But the fact is Red Dot do provide an exceptional service at not only a reduced cost but with proof of the increase. Even if the rolling road is not accurate from one to the next if you have it RR'd before and then after the power increase is accurate 'cos you are using the same RR.
I will be bringing my mate with his C2 to the next RR day and he has an Angel map. This should provide some evidence aswell.
Only problem there is Angel also provide excellent service. With a reduced cost and as good a comeback if your not happy as anyone else. As for proof of increase there is no doubt the only proof you have with Angel is how the car drives before and after and on that point I can't fault the results I had.
If your/anyone else's Angel map is perfect and you get exactly what is quoted then I will take back everything I said.
Also, on the subject of selling duff maps...If you look at formula one...Ferrari provide the engines to several teams. But they obviously give them the previous years engine not the newest and best engine...Its the same thing with remaps...why would you sell your best stuff to the competition? And if Angel were any good then they would produce their own
Ah verify companies claim using test data from a rival?
Now don't take that the wrong way I am in noway whatsoever trying to discredit Red Dot but it is hardly a fair way to do it. Also owning a rolling road is not a complete requirement to developing mapping. Maps can be tweeked while on tarmac with test cars and the right equipment. Ofcourse you will not have the same type of data but you can still do it.
Then incases where a generic map is appropriate. Like a car where lots of people are having maps with say a normal type induction kit and a catback exhaust for example. Generic maps have a place.
However in a case where there are experimental or more extreme less common mods such as changing injectors or cams or larger turbos a custom map with a rolling road setup will always be the obvious choice.
Again I will not question the massive advantage having a rolling road is as a development tool. But people have been tuning cars since they were first made.
I'm not here to smear any of the tuning companies mentioned in this thread. Yes a custom rolling road tweeked map, tweeked to match on any car in any spec of mod will have the edge over a standard map. But to discredit any map which is not custom to the specific individual engine is silly. Every single car made is fitted with a generic map.
Remember these arguments are happening over the mapping of factory standard low performance engines. Not race designed high performance engines. Where the level of perfection required means the difference between 1.5bhp and meltdown.
