[probee]

new MAF fitted and much the same..any ideas what it could be? I'm on my phone, I'll post some logs when I get in. I can do some more logs on the way home.... any blocks that will help us decide?

 

[Scotty_b]

Have you tried taking the battery off for 20 min to rest everything? May not solve your problems but would help with the new maf etc

 

[DPJ]

Do a TBA with Vag-Com.

Let's have a log of 002 and 114 together.

 

[probee]

Ok thanks I'll log them on the way home.. I did a TBA after fitting the new MAF.

 

[probee]

I appreciate the help with these.... im going to owe quite a few beers when this is over.

this log was taken after fitting the new MAF and doing a TBA. the first one is with wmi on T9
the second (T9 too) and all other logs are without wmi but on T7

im no expert but the log on 114 doesnt look good does it? the actual is all over the shop. wastegate? turbo? hybrid

 

[DPJ]

114 Actual load just isn't meeting requested as you say.

 

[DPJ]

Timing's really getting pulled back in the first log - look at that 3 in the ignition angle column!

But it's making the boost - no sign of Wastegate Duty Cycle issues.........

 

[probee]

its weird.... its obvious i have an issue but it doesnt actually feel broken. it doesnt like being pushed on timing at the minute. it would normally take T9 easily but as you say, in the first run it really pulled back, i knew it was going to be bad before i opened the log.

 

[DPJ]

I'm puzzled....

No sign of a misfire?
When did you refuel?

 

[probee]

it runs fine Dave. i did think plugs or maybe a coil pack on the way out but not actually dead yet.

i refuelled about 20mins before todays first log

 

[strugers1]

my mate brad maf went got a new maf and was fine but later the car was over boosting then not then over boosting it was weird he changed everything possible but put it down to sticky turbo veins
BUT then put another new maf on and all is fine
long shot but could be a dodgy maf like his??

 

[DPJ]

Aaron, are you doing a TBA each time you change your SPS3 settings?

 

[Wilko]

reset error codes. This will zero all adaption channels. TBA doesn't. Pull your plugs, and gap them.
Clean your wmi nozzle. Kettle decsaler works.
Check for vacuum leaks between the maf and turbo inlet. (this could explain low measured flow)
Drop timing to t8 an log again.
It doesn't look like you've got any serious problems. Boost control looks good, holding boost well over 6k, lambda control looks good, iat's are well controlled, timing advance isn't too bad at mid teens.

 

[probee]

Dave - yes recently (after reading one of your post i think) i have been doing a TBA after each change with the SPS.

John - error codes? as in fault codes? if so i only ever have one and that is from not having a post cat lambda.

ill check the nozzle but its only been used for a week or two (with demin water) and i havent been using wmi in these last few logs. timing was also dropped to T7 on these logs.

ill check the other points ASAP (sunday i would have thought)

thanks for all your help people

 

[Wilko]

yes fault codes. even if you have none, it resets the adaption channels to zero

 

[probee]

ahhh OK thanks John, you learn something new everyday although these days i seem to be learning 10 new things everyday...







i sent Dave an email today but im not sure if he has read it. maybe you know the answer....

do you know what the flow rate of the 386cc injector @ 4 bar is? ive read it somewhere on here recently but i just cant find it anywhere i think its something like 10-15% extra.. 440cc?

Hi Aaron!

Try this...
http://www.csgnetwork.com/fiflowcalc.html with 3bar = 43.5 psi and 4
bar 58 psi

286cc injectors will give you 36.76 lb/hr fuel.

sorry Dave, i had left work by then.. thank you for finding the info. i didnt want to hassle you for it.








EDIT: 386cc injectors go to 446cc @ 4bar if anyone wants the info
