My first log, be gentle with me LOL!!

[Mark300zx]

I did two runs that I think I consolidated into one, are there any glaringly obvious things wrong with car and my logging??

[binkylad]

Wow this makes zero sense to me lol wish i was brainy enough to take that in and comprehend, but wat are you trying to accomplish by doing such logs?

go easy on me please

 

[Mark300zx]

I am not sure if you are taking the piss or if one Luddite is trying to bond with another

 

[truCido]

Your MAF is giving low readings. A standard LCR (not mapped) should be running more airflow than that. You'll be down on power

Might be worth doing a log of 115 and 020

 

[Mark300zx]

Thanks,

The last column of 0s is an o2 sensor which I presume is either knackered or I have chosen an incorrect value for my car?

Is there a comprehensive list of what values are where, as some of the lists I have seen don't correspond to the vagcom when I connect it up?

 

[truCido]

0's are good on lambda from what I can remember although I'm very surprised to see 0's all through it...0 means 0 correction. I dont think thats the right block to log to see the lambda

List of logging blocks on here: http://www.ross-tech.com/vag-com/m_blocks/

 

[Mark300zx]

Cheers,

I think I have room for a third channel on the log any recommendations on what to use it for?

 

[truCido]

just do 003 at the same time, that'll then show you airflow (003), boost (115) and timing correction (020)

 

[LEE69]

Your g/s is very low if you look in this thread http://www.seatcupra.net/forums/showthread.php?t=284503 Chris gets 173 or 177 depending on what filter he's using.
You are around 197 bhp 158/ 0.8 = 197.5 bhp

 

[Mark300zx]

Thanks, I am fairly sure the issue is not mechanical as it came up good in the compression test + head gasket test, and no smoke from the car.

So do I have to do the next round of tests to get more evidence or does this mean my MAF is probably knackered?

 

[Mark300zx]

Ok went out today and did the values required, the runs were in 4th gear up to approx 6500rpm, if you gents could kindly cast your eyes over it I would be grateful?

[LEE69]

Maf was 158 then 152 then 151 it's failing.

 

[Mark300zx]

Can I ask how you get to that conclusion, not being awkward but genuinely want to know?

At 5400 it seems that MAF in all three readings is around 151/152, isn't that fairly consistent?

 

[LEE69]

Your g/s is very low if you look in this thread http://www.seatcupra.net/forums/showthread.php?t=284503 Chris gets 173 or 177 depending on what filter he's using.
You are around 197 bhp 158/ 0.8 = 197.5 bhp

Can I ask how you get to that conclusion, not being awkward but genuinely want to know?

I just go down the g/s and see what the highest is.
Bearing in mind chris is getting 173 and 177 and on my tweaked stage one i get 176 which is 220 bhp.

I can't read the logs like DPJ or Damoegan do (or other names lol) i can just see your maf is low

 

[Mark300zx]

Only trouble is I have a limited stretch of road to do this in, so I may back at various points slightly differently, I think at 5400 the MAF showing the same reading, so I presume hopefully it isn't degrading rapidly )

How does the boost look, I presume it reads above normal ambient air pressure so 1.900 mbar = .9 bar approximately ?

 

[LEE69]

What gear are you in 4th to flat out?

 

[Mark300zx]

I think the very first one I was in 3rd, but the last two were in 4th.

 

[LEE69]

yeah need to be 4th to get an accurate measure, not sure on the boost.

 

[Damoegan]

A Lee already said, low MAF reading for a LCR - I'd expect 160-170g/s for a standard LCR.

Boost looks fine, intake temps are fine, and CF's are fine..

You realy need to do a longer power run in 4th to at least 6.5k rpm.

I agree. Also, log no more than 2 blocks at a time.
