• Hey Guest👍👎 We're looking for reviews of your local CUPRA or SEAT Dealership - it's quick and easy to do: Leave a review now
On one of the runs we logged even though throttle was 100% down, the plate closed to 40% briefly. Not sure if that was the ECUs last ditch attempt at cutting boost or something?!?!?

Its a K03S yeah.

Modifications are:
Forge Motor sport front mounted intercooler
Forge Motor sport turbo intake pipe
Forge Motor sport diverter valve (yellow spring)
Green cotton air filter element
Denso Iridium IK22 spark plugs (0.8mm gap)
Milltek Hi flow sports cat and downpipe (2 ½ inch)
Milltek full cat back exhaust system (2 ½ inch)
Spec Stage 2 clutch
Peloquin LSD

The map was done by CC.

Could it be a faulty N75? (I have no idea to be honest!!!)

Doubt it's the N75. You can see the ECU pulling the load back in 003.

A log of 114 would be interesting.......

Have you mentioned the problem to CC?
 
The timing is very conservative too. I would expect some CFs from a stage 2 remap.

Agree, the boost is not meeting spec, there is no leak because the Duty Cycle is no more than 95% but it suddenly drops off at 5360 rpm, where I would expect it to still be at full boost.

2320 millibar is 1.42 bar (if you minus absolute) = 20psi. I belive that is pretty high for a K03s.

Would this drop off of boost result in the throttle valve closing as well Dave?
 
I can probably log 114 tonight. (what does that show?)

They said they only noticed the problem happen once and WE should look into it but wasnt that important.

Now we have the car its quite clear it happens every time!

They seemed to know their stuff but when it came to suggesting ideas for the fault they seemed stummped to be fair. Like I say they fitted a 4 BAR and his other suggestion was to swap the N75.

Not sure 100% but in my opinion fitting a 4 bar will have done nothing for fuel pressure if the standard pump can only do 3 (and he seemed to think it wasnt putting out 100% so call it 2.8 lol).

Another thing thats maybe worth mentioning is the car has Eurocarparts Lambda sensors not genuine VW ones if that matters? Everything is usually OEM but the price for new lambdas from VW was a joke.
 
114 shows specified load, and load corrections with duty cycle.

Std pump puts out a lot more than 3 bar. 4 bar fuel pressure increases the amount of fuel at each injection. It looks like it's mapped for it.

You've just had my opinion so far (and I can't see the cause yet) - wait until you get some more comments...


Nothing wrong with ECP stuff - except some of the really cheap alternatives they offer...

Wow, this sounds familiar.

Oscillating boost. Basically your actual is pulled back by the ecu after hitting more than whats requested, as it drops below requested it goes back up then drops again if spikes more etc...

I've had the twice on the rollers, where the atcual spike is way up on requested the ecu '**** itself'

You can see it on two rollers...

And Powerstation...

I think i might have cured this by using a Greddy Profec EBC, but i'll soon find out when i'm due to go back to Powerstation a week Saturday.

I've been trying to find a thread on it on vortex but i cant find it now for the life of me.

Sorry for the missing names, but you can tell what they are.

Theres a few people with the 4.5k dip, iirc Benny got it on his k03s stage 3 Revo.
 
On the dyno run they did (they did 3 or 4 pulls, presumably took the best) there were no dips in power visible.

When driving it only feels like small dips but the logs suggest its clearly doing something wrong.

It can be noticable throught the range at various points but usually its just around 6000.

I will try post the dyno graph up in a bit. Like I say though, you will see its strange that they stop at 6100 and its usually around then when it has its dip/hesitation.

EDIT....

DPJ - Do the lambda readings look OK? I didnt know if it was running a bit lean top end.
 
Here is some data from 114. Its a really long log and I'm not sure which bit was WOT. If needs be I can do another run with JUST the run data.

Does this help?
 
Also I have just noticed that on a run last night the requested boost is completely different to the other night!

strange
 
DPJ - Do the lambda readings look OK? I didnt know if it was running a bit lean top end.

A/f looks fine - running very fractionally richer than requested at the top end.


I'll opt for the first 20 seconds of 114

The pink line is the target load, the yellow line is the adjusted target load. The blue line is the actual load, . Duty cycle is at the bottom.

Is that a third gear run? If so, I'd say where actual is meeting target is maybe the power run and the car hasn't shown it's fault here...........

What would that suggest the problem to be Dave?


p.s thanks again, your time is very much appretiated.
 
Hmmm, cant remember to be honest.

Tell you what....

I will do 114 again in a bit and 100% make sure it did it (badly) on the run.
 
I'm puzzled because on the 114 run, load is decaying away as on 115 before, but in comparison the wastegate is closing fully again on 114, whereas it was different on prev run.

Log 107 with 114 this time, just to pick up prm.
 
Here are 3 new 107/114 runs

Code:
	Group A:	'107				Group B:	'114				Group C:	 Not Running
		Idle Speed	O2 Control	n/a	Diagnostic		Eng Load Call	Corr. Load	Engine Load	Bypas Dut Cyc/0-100%

You can really see the up and down on the WG duty now. Might be worth trying another valve to see if that makes any difference.

Nice logs tho, nice to see someone listening, making the effort and posting them up nicely. :D
 
Do you think we should buy a new N75 then?

EDIT...

Also why would the requested boost line somtimes change? Sometimes it sort of follows the boost line down and other times it stays flat and high.
