Problems with Stage 2+
vRS Carl:
I have tried a different dyno and got a similar result (263bhp and 281lb/ft)
However to keep things constant i have decided to stick with thew original dyno otherwise a whole host of other factors start being thrown into the mix (things like correct dyno settings, competency of the operator etc etc)
I have used the original dyno on 4 previous occasions and always found it to be spot on so don't see the need to check on other dyno's.
I only did a different dyno just to satisfy my own curiosity
Carl :happy2:
revo carl:
So how is this a problem with code......
Would this not be put down to a discrepancy with the dyno you're using.....
what dyno's are you using?

Car does what it should on the road but not on the dyno = no problem with the software.
The ECU's in these cars are load based, they will react to differences in conditions, temps, etc. Winter figures will differ to summer figures, etc, etc. They're tuned for road use, you don't drive the car on the dyno?!
We see cars acting differently on the dyno to the road all the time, but if it's spot on for the road then! :happy2:

The reason i am saying i believe it is a problem with the code is due to the Data Logging results
The car went on a Dyno and produced 265bhp and 285lb/ft (also got 263bhp and 281lb/ft from another dyno so the car is consistent on 2 seperate dyno's)
On each Dyno the car would not request maximum boost.
However after the dyno session i did last i did 8 logging runs over a period of 2 hours (the first one being about an hour after the Dyno session) the car had not been changed in any way and the settings were still the same. The car requested (and made) maximum boost. To quote someone who viewed the logs they said if they had not seen the car on the dyno themselves they would have believed the Data logs were from 2 different cars.
I am not saying it is definately the code but it would seem a bit odd that you can turn the timing advance up to 9 and it will show now timing pull on any cylinder (they all remain at 0 from 2000 - 6000rpm) on the dyno yet the minute you put the car on the road Timing 4 shows pull on some of the cylinders and gets worse the higher you advance the timing (didn't take any further than timing 6 as this started to show 5.3 on a couple of cylinders)
Now if that was just happening on my car i would believe the fault was with my car. However on 3 other cars all at the same level of modification i find it hard to believe that they would all have the same problem at the same point in the Rev Range.
Plus i know that Stage 2+ should give a reliable 280bhp and 315+lb/ft.
Revo Carl please don't take this as me slagging your code off, Im not, The car on the road is like an Exocet missile and the way it performs i am more than happy with. What i am trying to highlight is that some people may be spending considerable amounts of money trying to fix a problem that may not be there in the first place. I personally spent about £400 in replacement parts to negate the problem of Boost leak etc. I am very very happy with the REVO product. I am just not happy that something is holding the car back on the Dyno.
Carl :happy2:
