RR day at PD Tuning on Saturday 16th July- Newcastle area

[Cupra R]

I'd of thought your fuel rail pressure would of been higher Dom, Revo certainly requests more.  If their were more fuel then you MIGHT not get as much timing pull.

Just a guess as I'm no mapper.

You need the map sorting, wouldn't want to be running round with that much timing pull myself, although I know of others who have.

I was told by the mapper there is no need for more pressure, as the actual volume going into the cylinders is enough at that pressure, I asked the same thing, and he was adamant. I was under the impression that a minus number is running rich anyway. The timing was fine until I had the torque limiter raised with the dsg map, it didn't leave shark with those levels of pull.
I've been in touch wil Ben and he said he would alter the map. I thought about 4 was a nicer number to be running at

You didn't monitor revs on the above log, what revs are you doing at the -9 pull?  Is this at the same point where the torque limit has been raised?

Also, timing pull for me woud be a result of a Lean mixture rather than Rich. (maybe wrong)

So was the dsg limiting the timing then if it was fine after being mapped but only high after the dsg remap?  Your dsg seems strange, it does all sorts of strange things to the maps.

Or is it a bad batch ofof fuel

I clicked on the wrong box for the 3rd set of blocks
It was a clean rev from 2000pm to 7000rpm or  so.
The dsg limits the torque by changing the timing I was told but you cant see that by that set of measuring blocks.
If I knew how much a pain the DSG would have been I would have got a manual, I only got a DSG so I wouldnt have to worry about clutches!
I logged it a couple of times now, first time was -6.5 pull, I logged it the other day with -7 to -9, but just got my laptop back, so did another log today.
At the end of the day, I'm not a mapper and only go off what I've been told

[Cupra R]

So at least it sounds like its not the maps fault, sounds like it's with changing the DSG map.

Only problem means it's another road trip for you, tell them to go easy on the brakes this time 

Stick with it mate, sure you'll end up with a solid car.

they have their new rolling road being fitted as we speak  Theres an open day there on 25 Aug Dom, might be worthy of a vist/meet then

[Blade]

Wow, megga pull there Dom. Pull = Heat. As said earlier, i would be questioning the map as your not even getting standard fuel rail pressure at some points.

[Andy]

have you tried logging it with the pdt map you have

[heavyd]

Don't think the fuel pressure is much of a worry, as it's mostly a higher pressure?
I would have gone to the open day sy, but Nissan nicely decided to move the august bank holiday to April so got to work all day I'll probably head down to the September RR day as I'm off work that week. See how good the Baspro dyno is
Think I'll switch back to the stage 1 map until it gets sorted...
This bloody car is a right pain. The joys of tuning eh!
Car drives well. But it Just goes to show how worth while datalogging is

have you tried logging it with the pdt map you have

think I'll swap over to that one now you mentioned it, time to find a quiet road

[heavyd]

Well, the PDTuning map looks a lot nicer,  theres hardly any timing pull at all, big difference in power though
At least I know what the problem is!

[Andy]

Can Dave not alter his map to get more power to save you a trip down there again

[Janner_Sy]

if that was the case he wouldnt have swapped to Shark in the first place though

[Andy]

Prob,s right just an idea

[chungster]

Power isn't everything you know...rather have an engine that's going to last and not have such major timing pull issues! 

What's the boost requested on the Shark map then?

PDT's map has a peak 1.4bar request (altho it actually spikes to 1.8 bar  ) with 110 bar fuel pressure.

If the Shark map is asking for 121 bar fuel pressure what boost is it requesting? Must be more than PDT's I'd have thought.
