POLO TURBO...nearly ready.. SEAT owners watchout!!

[h17och]

pj i think its a different code.

the one your thinking of is something like 'engine speed exceeded!! warrenty void '

 

[pj1985]

He didnt say what the code was just that it had warranty void.

I seem to remember reading somewhere that throttle pedal is not supposed to be adjusted to go to 100% but cant remember why it was now. Was on a thread here somewhere I think.

ECU is probably backing timing right off, this will effect boost. My Apexi is at 90% most of the time due to a weak actuator I have and the amount of boost I run. You on self-learn duty? Apexi starts to learn at throttle positions above 85%. Mine throttle is at 100% on the avc-r without pushing my foot right through the floor.

Need to log timing and AFR.

 

[ibizacupra]

its engine speed warranty void not boost.

Is apexi in learn mode if its tripped to run requested boost or fixed duty cycle.. fixed should be fixed after all

max boost exceeded is its gone beyond what it was expecting (in map) at that given moment.

dbw weirdness going on I suspect with not all controls under Me7's control now.

The setting I've been running on is on learn mode... would this also mean the speed should be calibrated?
I dont know if it is... My speed is always way out then what the apexi reads.
I will try turn off learn mode and see how it is... today it was ok fluctuation wise, holding constant 1.6 from 4500 onwards, but couldnt get to over 6k again It either spins or the road isnt long enough!

I have logged timing and boost, I wil try get it on here never figured out how its done! Hopefully u lot can read it, I understand the boost but nothing regards to timing..

I really need to get my suspension on and back to jbs I think, I want a dyno read out but something seems to be missing.. boost is there, im pretty sure fuelling is there too! My EGTs havent gone above 750 with a good thrashing to 130mph..
Timing

Will do A/F run tomorrow, and really hoping my bloody gauge comes quick or I;m going to have to buy another one

I didnt get to go all out, but tried my best had a few quick blasts..

 

[HTC]

It doesn't matter if the road speed is out, as it will be uniform. 60mph will always be the same amount of km/h in the avc-r for example. You should set you gear values though. Just drive the car and copy the value on the left of the screen into the setting point for each respective gear.

To my untrained eye I don't see much wrong with that log. timing pull doesn't seem excessive and the areas where actual and requested boost differ loks like you might have been just coming off the throttle?
Others will chime in with better interpretations I'm sure.

You really do need to find a longer road and really get on it to know what the engine is doing at the limit. Log overall timing too and lambda.

Also if you can take a look at this guide it makes it easier to read and see trends, or just post an excel screen if you have it.

Thanks guys for the input...
Just noticed that Bill... weird max boost requested on those runs was ony 1.3bar


Thanks guys for ur input, going on the M1 soon for a real good run and will get the right logs on here tonight..
Going to set the values today for gears, go max in each gear and copy the values into the settings screen, see what happens, also then try with learn gear off.

 

[HTC]

You don't have to drive at maximum speed to set the gears. The number is worked out by the RPM divided by road speed so it will stay the same what ever speed you are at in a particular gear, like the gear ratio.

Go into etc --> gear judge and drive the car in 1st gear (just cruise, you don't need to floor it). The value on the right of the screen should vary up and down by a small amount. Just enter the number it sits on the most on the left. Do the same for all gear.

Think about adjusting start duty and feedback values too if boost overshoots or surges. All in the manual.

Bill, if he is running a separate EBC, does it matter if the requested boost is off since there is no N75 control or should the ECU request the max boost set in the EBC by JBS?

I mention it as deviation is deviation, and the ecu still has control over the throttle position and can close it when its trying to operate a request which is outside of its control now. I think he said his throttle angles were not 100%, and this I believe is an adverse effect on part load, part throttle application when using an external controller for boost.
Just because you put the pedal to the floor does'nt mean the throttles fully open as Me7 is trying to run best angle for requested laods. (which are now frigged beyond its control)

 

[HTC]

Thanks Bill, I forget about the ME7 throttle control as I have the cable type. What my foot tells it to do, it does!

so does my dbw unit.. courtesy of DTA now tho. open and closed and everything in between. 1:1 correlation.

I noticed that when I floor the pedal, the throttle shows 100% (AVCR) then starts to drop down like to 80 something %...
I guess what u said is happening, the ECU is adjusting the TB itself even tho I have it firmly pressed down because of the difference in requested and actual boost?

Something just doesnt feel right


Also I put in a brand new 044 pump thinking it was faulty and the new one was much quieter on priming and even so when the car was on compared to the old one but now a couple of weeks later it sounds just as noisy again, and I;m sure the car doesnt pop and bang like it was when I got it back from JBS the other week...

I am wondering if i'm getting a fuelling issue aswell

Wonder if what u mentioned Bill about the original fuel lines being able to blow but not suck causing me a problem...

Can anyone confirm when the pump is on, should the sound be uniform all the time or does it fluctuate, e.g not when on idle when u turn heating on (momentarily power drops) but this happens constantly, the pump noise goes up down up down, not louder and quieter just whining high pitch then low pitch.?!/!/?

Thanks HTC I changed the values on the gear judge, need to see if it makes a difference...
Only thing is, I like the fact I can play around with the avcr settings, but was hoping it was all perfectly set when I got it back...

 

[HTC]

I would say that your pump should not make a pulsing noise. I have a walbro and the sound is level and constant. I'm running an S3 intank lift pump.

 

[h17och]

i run a 044 and its a constant noise. what pick up pump you got?

HoocH

 

[HTC]

A pressure gauge near the fuel rail will help diagnose.

Your pump is mounted at the front of the car in the engine bay is'nt it (memory fades)... and like I suggested, its suction side, thru the long length of std bore pipe will not help itz delivery. they blow well, they dont suck so well. Power to the thing also somethign to check, a good healthy battery voltage at the pump is req'd. Pulsing sounds like its scavenging to me which wont do its life expectancy any good.

Have you physically checked fuel pressure? bet its up and down on you..

 

[HTC]

Also, when was the filter last changed. JBS couldn't map mine at first with lambda all over the place. New filter and problem solved.

Bill, my walbro is mounted under the car at the back next to the filter, is this a good place considering your last comment about sucking/blowing.......oo-er.

 

[ibizacupra]

Close to pick up pump (in tank) the better I think personally. thats where mine lives. Its suction side is short and close to the delivery side of the in-tank pump..

when the inline is mounted up front like on the polo install, then the suction side has a long length of small bore pipe to suck through...... pressure drop down the pipe is likely, as its demand for fuel will outperform the in tanks ability to supply - hence surging as its scavenging on its suction side.

my theory..

Your filter suggestion is a good one also.
