Hello folks. Since getting Revo stage 2+ last week Ive had the engine light come on twice. fault code saying engine running rich on bank 1.
So I bought a new select+ switch(£126 brand new :star:) as I thought I might need to change some settings. I never had the engine light come on until I switched from bluefin.
So Dave at PDT set it up with B9T5F5. when on the rollers it was pulling 5degrees of timing.
I did a log of that setting yesterday and it seemed fine, but the car had just warmed up.

So I changed the settings to B8T6F6 to see if the light came on, and leaned the A/F ratio out a bit. Bearing in mind I', running the stock I/C
I did 2 runs back to back which gave different readings

I was just wondering if anyone could shed any light on which way I should progress with these settings, as people on here will have had more experience with this than I have!
Thanks in advance for any help :happy2:

I'm no expert on VAGCOM (not got it myself),
but is your boost not a little bit low for Stage 2+? :confused: Should it not be requesting 1.6/1.7 bar? Yours seems to be requesting and making around 1.5 bar which is what Stage 1/2 should get IIRC..
*Edit* Cancel that, just looked again and the boost is fine.. :ashamed:
-
I would leave it on B8 T6 F6. Your timing pull is minimal which is what your aiming for.
B8 T6 F6 will give you more power than B9 T5 F5.
You could try B9 T6 F6 and see where your timing pull goes. Upping the boost or timing any more is not going to give you that much more power.
Unless your chasing numbers I would leave it as it is on B8 T6 F6 :happy2:
-
Thanks carl :wink:
Just hope then engine light stays off :happy2:
-
More importantly, how are you finding the car now with the Revo Stage 2+ Dom? Better than BF I would guess..?
-
Well after a week, I would have said marginally better, but the hancook winter tyres, fwd, 350bhp, slippery roads aren't a very good combination for comparison :laugh: bring on the sun! There's more lower down grunt than before, but just get too much wheelspin. I had a non resonated pipe fitted last week which makes a nice improvement over the resonated system, not too loud at all, but makes it sound like it should have done from the factory. Might polish up the resonated section, someone might be after one with a bit of luck. Looks like an fmic might be on the cards for summer :popcornsoda:
Shame u dropped out of the motorscope day, would have made a nice comparison :sad1:
-
Both sets of logs look fine, I had that same fault code on mine last week, wad a faulty MAF, I could clear it but would come back within 30 miles, with new maf its fine.
B9 T5 F5 Wont make much difference to B8 T6 F6 as far as power figures but log it again one the weather warms up as this could result in more timing pull, its also worth it to log your EGT's if you remove fuel but add timing, they usually arent an issue but its 20 mins to check for peace of mind.
Glad you got your exhaust sorted, things have been crazy busy here this week plus I was off ill on Tuesday/Wednesday so couldnt get you in.
Good luck on the dyno day, not that the figures would be dissapointing :innocent:

Yeah tell me about it mate.. :sad1: Would of been ideal that, as we have the same mods bar different intakes (EVOMS/Twintake).. If anything changes, i'll let you know mate.. :happy2:

Oh oh, engine light on again :sad1:
Hope its the MAF and not a new fuel pump :stupid: if it goes then it looks like an APR pump is on the cards :scared:
How much was the mew Maf Dave out of curiosity, and what deaks can you do on a Forge Twincooler?
-
What pump do you have if your already running stage 2+ heavyd??
-
autoech.....
From the searches that I've done. The
008584 - Bank 1; System too Rich at Idle
P2188 - 008 - Implausible Signal
fault is either Maf, o2 sensor, or HPFP internal leaking fuel.
The first fault showed it appeared at 17.45 last friday, which was when I was still at PDT :sad1:

Then the components that PDT had removed maybe would be the 1st i would look at if thats true.Hopefully one of those 3?

They hadnt touched any of them to my knowledge, they had an air sensor from the dyno going into the engine bay, dont know where, and thats all they touched in the bay.
Just did more logs and fuel trims and lambda sensors are all ok.
Looks like cheapest option first, then onto the wallet emptiers last!

Take a look at your fuel trims and post the results.

doesnt look too promising :sad1: :sad1: :sad1:

I have a spare MAF here if you would like to try that first. I'm in Guisborough if you can collect it or can post it if its too far for you to travel. Its used but works fine. :happy2:
-
There is nothing wrong with those.
As long as there isnt more than a 5bar difference that is sustained it's fine. The two bits you have at 5.43 and 6.03 are brief so I wouldn't be concerned.
Edit - Knew i should have read the previous posts :laugh:
Block 032 is your fuel trim. Should be somewhere between -8 & +8 in both boxes :happy2:
-
Post up the trims:

The above is the rail pressure :wink:

How do you get the screen shots from excel up on to the thread Dom? :ashamed: I'll post some logs of mine to compare if you want?
-
Ill do some more logs tonight. New maf on order from stealers. All u need to do is have the logs up on the screen and press the printscreen button on the keyboard. Open up 'paint' then click paste, crop it if you wish, then save it as a jpg file then upload to photobucket etc.
Thanks so far for the help :happy2:

When I press the 'Print Screen' button it doesn't do anything? :confused:

You don't need to log.
Just switch on the ignition, fire up VCDS, select engine, click measuring blocks and type in 032. There will then be values in the first 2 boxes. These are what should be within -8 to +8

It doesn't appear to do anything but it does.
As HeavyD has said. Press Print Screen, Open up paint, Press Ctrl & V (or click paste) and the screenshot will appear. :happy2:

It actually does exactly what it says. If you want to just copy the active window then press ALT + Print Screen.

If all else fails, ask the experts.. :happy2:

Can't get it bigger though.. :confused:

Size isn't everything you know. :wink:
Just select the section you want and copy/paste into a new paint window.

Like this.

Here goes. It seems that the high lambda value in the first column is higher compared to everyone elses logs?
Thanks for the Maf offer jon-tsfi, but after thinking about it, I'd rather try a brand new one to guarantee it isnt the MAF at fault before spending anymore of my hard earned!
If fuel had been leaking, musnt have been much, as my oil was low again!, only put a litre in teh other month :stupid:
Thanks for your logs Ben and hedge :happy2:
Lambda (Idle) Lambda (Partial)
Self-Adaptation Self-Adaptation
% %
-6.1 0
-6.1 0
So upon research, the idle is controlled by the primary o2 sensor asell. how easy is this too change?
-
the lambda readings are within tolerance (a minus figure means its removing fuel as its running a little rich) mine were -8 and with the new MAF they are -1.2.

Well after £108 on a new MAF sensor,

Hope fully fingers crossed the fault doesnt return :jumpmove: At least the values are better than before
I lost the bolt for the maf that goes into the twintake though :sad1:
Think I might sell the car on at this rate!!!!!!!
Thanks for the help folk :happy2:
How much will it be for a twincooler then Dave?

Oh well, the joy was short lived........

Has anyone any other idea what it could be?
Does anyone know if theres any reason why it would be running so rich on idle, yet ok readings whilst driving about? If it was the lambda sensor, would the readings whilst at revs also be higher, and if it was a vacuum leak, these readings would also change, but the continue to remain constant whilst at high rpms?
A bit daunting considering MOT due very soon, bet it fails on emissions :sad1:
Is anyone after a maf :signLOL:
-
You know that there's 2 lambda sensors right? try and swap the old with the new and put the new instead of the second one?? just a thought :smiley:
-
I wasnt sure if they were the same part number. By the looks of it I might need to up the fuel ratio, as it looks like the timing is too rich when the timing is pulling.
'd just stayed stage 2 b;uefin :surprised:wish I'
-
Why did you change the lambda sensor?
-
I didnt. I was trying to rule things out that could be causing the fault. Only fuel pump, lambda sensor and maybe the pcv left from what I can gather that can be at fault?
