Vag Logs from mapped Cupra R

Chaz · Jan 11, 2007

Here is a log (115) from a mapped Cupra R. This isn't my car and I drive a Leon Cupra, I am not sure what the boost levels are suppose to be at. Does it look ok?

Code:

Group A:	'115			
RPM	Load	Absolute Pres.	Absolute Pres.
	
 /min	%	 mbar	 mbar

2520	118.8	1990	1570
2680	123.3	1960	1630
2880	124.1	1940	1620
3040	127.8	1920	1610
3240	130.1	1910	1660
480	133.1	1900	1680
3680	130.8	1880	1680
3840	130.1	1870	1650
4000	130.1	1880	1640
4200	133.1	1860	1670
4360	136.8	1850	1680
4560	139.8	1830	1700
4720	141.4	1820	1710
4920	143.6	1790	1710
5080	142.9	1800	1730
5240	141.4	1820	1710
5400	137.6	1830	1710

No it doesn't look right. Actual boost is well below requested all the way. What is the map?

Chaz · Jan 11, 2007

I dunno, will find out... also.. I am not sure why the title is absolute pressure and not requested and acutal boost (as per my Leon) ?

Dan Cupra R · Jan 11, 2007

It was mapped by Will @ P-Torque in a group buy on SCN back in November from here http://www.seatcupra.net/forums/showthread.php?t=101015

However, when it was rolling roaded it made 179.2 BHP & 191lb/ft.

the guy from JKM said the car was losing between 20-30bhp due to it running rich, Which would suggest sort out the rich running & the car should be about 200BHP suggesting that the map works?

Ive got the RR print outs as well if u want a look?

acidstrato · Jan 11, 2007

titles are not important, requested is the left, actual is the right,

defo not a healthy bunny, take it these are dans

would say dodgy leak, dodgy n75 or dodgy map...is this another ptorque map? who was the other guy with a ptorque map that was having problems? be good to compare the requested boost levels

Please don't stone me....

Could someone briefly explain logs to me...

Chaz · Jan 11, 2007

I did suspect a boost leak when Dan and I were talking about it last night...

the problem is air fuel ratios are calculated by the ecu from the values it gets from the engine sensors, therefore the ecu should automatically adjust the fuelling itself, rather than older cars where you would have to adjust this manually

things like lambda sensors and maf can cause dodgy air fuel ratios or a dodgy map

but that log tells you its not boosting good anyway

laptop, vagcom software, interface cable, car, click start, nail it low rpm to redline, click stop

jobs a gooden

here is the MAF log as well.. I think it looks ok...

Code:

the requested boost is all wrong, i just cant get my head around it

starts off at its peak and just keeps going down??

maf is adequate

yeah - its weird....

But then, is that just how the map works... drops the boost towards the red line... ?

That was me, here's my log from a while back. The requested is very different. Why is Dan's requesting 0.9 bar when mine's requesting 1.1 bar if they're the same map?

jj10 · Jan 11, 2007

So, it basically tells you what your engine's up to...

Cheers Acid

your not wrong but it shouldn't start dropping till about 5k, and peak should be much higher, atleast 2200 (1.2bar) at a guess

Do you have more mods than me? Maybe that could be why, all I have is DV, Airfilter & exhaust

perhaps Dan does has something dodgy, like a fecked lambda sensor, might make the ecu pull it back? sorry dont know what values are normal for logging them.

umm,, 2200mbar = 1.2bar?

How does that work? I thought 2200mbar would be 2.2bar or do I have that wrong?
