Experience of APR Maps

[vRS Carl]

doubt its the pump. jkm would have logged all the specified and actual fuel pressure as soon as there were issues.  have you got your cable back from ross tech yet carl??

Yes came last week but i am away till this Friday

Bacillus is right, I am running APR stage 2+ software with APR hardware as well.  Had APR stage one since 18K, stage 2 since 39K and stage 2+ since about 60k. Presently on 89k. The only issues I had was on their stage 2 software in the early days (2007) when people were getting fuel cuts due to the standard HPFP. This was solved very quickly by APR writing an update for the stage 2 map.  Since getting stage 2+, I can say that I have not had any issues at all, not even the Flat spot at 5200rpm on 2.0T cars that people talk about.  Not had it on the RR since stage 2+ but at stage 2 (on Awesome's RR) it made 260bhp (242whp) and 296ft-lbs of torque.

my product review of APR Stg1 is on here and fits exactly what I was after, as Gaz says clean strong power. (K04 for me)
In fact the new update v2.2 is even better  
20k miles on stg1 so far and loving it. Any issues have been dealt with open and honestly by Awesome and APR 
Also depends a lot on who your UK dealer will be ?

bacillus arent you running REVO ? and youre the highest K03 I know  

[vRS Carl]

I dont mind travelling to get it done properly.

Awesome is only 25 mins from my folks.

I generally use JKM but can always go to Awesome one weekend when at the folks

bacillus arent you running REVO ?

Correct...   

[tony_danza]

My stage 2 REVO made 270BHP and 330fl-lbs on Awesome's rollers.

I can't comment on REVO's stage 2+ performance, I don't have it. However, Bacillus' S2+ car well out performed mine on the same day. It was also highly praised by Jim.

I will have it in a few weeks when the HPFP arrives, so may well revisit this with my views. I'll be watching this to see yours if you change too. I'm not so blind as to not take notice, although I do seem to remember JKM were involved in the case of blaming REVO in the example I gave above that turned out to be hardware.

My K03 car had a recall on the low pressure fuel sensor too, seems a common VW f*** up - worth a look?

[vRS Carl]

Well the car is back on the RR at JKM on saturday so will see if there are any changes as i have replaced the MAF & MAP sensors since last time.

Low pressure fuel sensor will be the last thing i check before jumping ship as if i replace that i will be around the £1k chasing a phantom error.

Cool - keep us updated then.

I hate to see someone having to throw money at a car chasing a fault, I just hope it isn't something stupid like a fuel sensor after all that.

[vRS Carl]

To be honest i don't care anymore i just want it sorted.

I will also publicly apologise to REVO if it turns out to be something other than the Software. I am just finding it hard to see 3 different cars have the exact same problem at the exact same point.

I've still yet to decide wether it will be the APR or Shark performance ship i go to

have i read one of your previous posts correct carl.  i remember before your car wasnt perfoming on the RR but was on the road. is it now not performing on either??  

if you are going to the shark perfomance open day ben should 100% have the stage 3 installed then.  read a reply to someones post on brisky earlier where a guy on there "sherlock vRS".

He is an official REVO dealer and has had REVO custom stage 2 map on his car(as a demonstrater), and really rates the shark perfomance stage 2 after driving bens. basically he said it didnt have the aggressive surge of torque but instead the power delivery was very very good as was the torque.

so based on that i wouldnt expect it to beat REVO performance wiae, but match it with a different delivery whyou are afterich might be what

[vRS Carl]

The car is basically hit and miss.

One minute it's like an Exocet missile then the next it isn't.

This is what is happening with my car

Me - Mash the Pedal to the Floor
Car - Happy fooking days sunshine lets go you want power then i give you POWWWWWERRRRRRRRR
Me - Face like 

Next time

Me - Mash the pedal to the Floor
Car - hang on a minute will you let me catch my breath. Okay here we go awww sh!t run out of Revs, sorry big fella maybe next time
Me - Face like 

Next time

Me - Feed power in
Car - Quick lads get some more coal on that fire he's gonna ask for more power in a minute, In fact fu*k it give him it all now
Me - Face like  but 

Thats what it is like living with the Blue Bullet at the moment and has been for a while.

All the logs now basically resemble the RR logs. I can set the car on Boost 9 Timing 9 Fuel 9 and get no problems at all log wise

But i must remember (all together now) There is no problem with REVO software, There is no roblem with REVO software. Woooosahhhhh

Carl

[Janner_Sy]

thing is its not as if you ghavent replaced everything.  My only thought there is if it was the map would it not be a consistent thing??

[Janner_Sy]

have you thought about a jabbasport custom map. i have heard nothin but excellent things about them.

[vRS Carl]

Jabba do have good ratings but i want to see decent dyno plots

Not interested in numbers just more the delivery and how well it holds the power etc.

Completely ignoring whos code this is, lets look at it as a process of elimination.

It is intermittant and the car as you say, is capable of producing what it should when it gets it right. Yes?

The code is a fixed set of values that doesn't change (until you do it with the SPS). The ECU is what manages those values, so it requests X based on those and if the engine gives X then everything is fine, if the ECU gets Y, then it'll do what it thinks is best - which could be anything from backing it off 5% to having a total spaz and putting it into limp mode.

It could be a bug in the code, there might be a value based on the assumption that X piece of hardware exists, when in fact it in a smal minority of cases it is Y and therefore doesn't perform in the way they expect. But then why is it fine when it gets it right?

Are there certain situations that the fault is more apparent, when it is hot, WOT, etc etc? I assume you have logs from when the car faults? What is different?

There's plenty of things that don't register either. We found with my old car that when the butterfly stuck on the EGR valve because it was full of oily goo it'd choke the car for a moment and cause it to stutter. Nothing in the logs indicated this was happening, we found it by chance. Likewise when the actuator was sticking, it'd request boost, not get it and back off, then the actuator would come free and deliver a sh*t load in one lump.

The wrong low pressure fuel sensor didn't register either, there could be a load of other similar examples too.

Asking a map writer to diagnose a fault is difficult. They only know so much and although many deviations in logs point to certain areas of failure, without a hard fault code, it's a best guess. Common faults you get to know, something strange and where do you start? That's why someone's eyes and hands are essential at the same time.

What you need to do is stop scattergunning bits at the car, you've wasted a grand so far either by your desperation to fix it, or by someone else's bad advice. You can't diagnose a fault by throwing stuff at it.

I'm sure someone on here can help if you post up all the fault logging stuff.
