Autotech vs APR HPFP

[Janner_Sy]

heres a spanner in the works. just had revo stage 2+ installed yesterday, it only requests 125.33 bar of fuel pressure
Cant understand how stage 2+ reueqst less than the stage 2 that asked for 129.99bar

Is that not adjustable with your SPS switch?

[vRS Carl]

You can adjust the fuelling to make richer/leaner but not the Rail pressure.

Whilst I was trying to find the phantom issue with the car (obviously it would never be the software ) when I had 2+ I tried fuelling from 4-9 and it never made any difference to the rail pressure.

[heavyd]

Revo carl response was because its 12 degrees outside, the engine with reduce the requested rail pressure because of the heat

So that was your car that made better figures on Stage 2 instead of Stage 2+?  

How could that possibly be? Boost leak?

It must have been

On Stage 2+ with an APR HPFP it made 254bhp and 260lb/ft. Without leaving the dyno it was flashed back to Stage 2 and made 270bhp and 300lb/ft.

But there was nothing wrong with the code, it was the car

WTF  that's rubbish surely.  The UK average temp is 13°C iirc

Well considering my logs above were done in July then i would have to agree 

[Janner_Sy]

Maybe boost leak isn't the 2012 excuse  

@Dom

What's PDTs take on it?

 You should have took that APR offer

PDT said its the latest stage 2+ revision.
I managed 350 bhp with the great white shark map which only requested 120.99 bar?
Car goes like s**t off a a stick again, but now I've gone stage 2+ I've got the dreaded overboost back again, I should have just stayed stage 2
Hindsight is a fine thing
The APR offer was great, but it was the fact that the closest dealer was miles away, so if I had any issues with the map, would have been a total pain.
I was put off by the big torque numbers that mike got, and the large amount of boost,  now my car only makes 5lb/ft less with about the same bhp as mike, pushing 2 bar of boost

[Janner_Sy]

Think mike has a decat dp so his will have more torque than a normal Stage 2+

[heavyd]

oh well time to eat humble pie  
did some datalogging again, looks like this new map doesnt follow the same rules as all the other maps I've had
seems like it does change requested rail pressure dependant on unknown variables
3 different rail pressures on 3 sets of logs so far

[ktlstar]

interesting that!

[vRS Carl]

Are you sure you know which map this is as you do have a fair selection

[heavyd]

On this occasion I'm sure, this is only the 7th time this year my ecu has been flashed
Logs were done yesterday and this morning 

[Janner_Sy]

are we below 12Degrees now then lol
