Does this log look ok?

[vagman2001]

Logged these in 4th gear as you were saying...i changed the plugs, fuel filter and air filter since the last logs.
There still seems to be timing pull any ideas?
I also logged 001, 112, 030 like you were saying 8bit im not sure what these values should be at so im looking into a hole with that one im sure you will know more!

Horrid to read, but you're pulling up to 8 degrees of timing... ECU has a limit of 12 degrees, after that it can do no more and you're in danger of pre-ignition doing damage to internals - safe bet it will be your rods that get bent first.

A wide open throttle run through the gears with a long stint in 5th/6th (especially a quest to find the top speed of your car) will give rise to higher cylinder temps and will likely induce more preignition... Along with higher cylinder temps, higher intake temps / fuel with a lower RON rating / oil vapour reducing octane of fuel / higher boost levels can increase pre-ignition.

For this reason it's generally said (although the origins of this assumption I'm not sure) that CFs of up to 6 in a 4th gear WOT run are acceptable, to leave some headroom for flat out runs / slightly poorer fuel etc.

Your last log shows fuel dumping - 1.8Ts with K04 Turbos have EGT (exhaust gas temp) sensors which are designed to increase economy and are the reason why a 225bhp car can still easily see 30+ mpg.

Stock fuelling is targeted at 0.953 lambda throughout the rev range under wide open throttle, until the EGT sees temps exceeding 920 degrees C, at which point fuelling is richened up according to an enrichment factor in the next column on block 112 in an attempt to cool cylinder temps down. This is why your temps peak at 945 and then start dropping even though throttle is wide open. I would guess that by the amount your car is fuel dumping it's running pretty damn rich at the top end and starts to feel a bit like it's running out of puff on a run like this?

Apparently in Germany it's illegal to mess with fuelling when remapping a car for eco reasons, so a lot of remaps only adjust timing + boost and rely on the EGT sensor to keep things cool (other remaps are programmed to run richer under wide open throttle right through the rev range to keep temps lower across the board). You can see whether your map is based on one like this by logging block 031. Plant your foot from 3k revs and if you see a 0.953 repeatedly you've got one of these maps.

Also in the first log your actual boost is not hitting requested... Can you log block 115 and 118? This will show requested boost by your ECU, actual boost your turbo is managing, and will also show N75 duty (this is the valve that operates waste gate on your turbo. If this is 100% and turbo is still not hitting the requests you likely have either a boost leak or a dying turbo. Also block 032 might come in useful as if you have split pipework it may show up in here.

You will also get intake air temperatures on 118 which are important when looking at timing corrections.

 

[8bit]

Made a mistake - meant to say 001, 031 and 112, not 030. In any case, your turbo is meeting requested boost but only just and it doesn't sustain it, suspect possible boost leak - usually they spike higher than requested then fall back and hover close to request as the revs rise.

As above, your EGTs are into the protection range (above 920*C) by 5500rpm, that doesn't look right to me. We'd need to see block 031 to be certain but my gut feel is it's running a bit lean so cylinder (and consequently exhaust) temps are getting too high. You can see in the last column on the second log shows the ECU dumping extra fuel to cool things down, I could be wrong but it may be that the injectors are already maxed out by then and there's no room for more fuel for cylinder cooling.

Can you log blocks 002, 031 and 112 - that way we'll see injector pulse width, actual vs. specified lambda readings and EGTs. Also log 115, 118 and 020 as suggested above to give boost, N75 duty and corrections again.

My gut feel is there's a boost leak causing the car to run lean and cylinder temps to go high, but the fuelling system has no headroom for the ECU to dump fuel to cool it down.

Thanks for that Ben ill log that tomorrow...so if I get 0.953 all the time iv got a map that only has timing and boost changed? Which type of map is better?
Just at 3k the power kick is huge doesn't feel normal the rest of the rev range with wide open throttle can feel on/off power but a lot of power at the same time if you get me? High rev range does feel a little flat alright.

Also in the first log your actual boost is not hitting requested... Can you log block 115 and 118? This will show requested boost by your ECU, actual boost your turbo is managing, and will also show N75 duty (this is the valve that operates waste gate on your turbo.

Also block 032 might come in useful as if you have split pipework it may show up in here.

You will also get intake air temperatures on 118 which are important when looking at timing corrections.

Ill log 031, 115, 118 and 032 tomorrow, the turbo sounds ok there's no crazy noise from it, open throttle there is a loud swoosh from 2000 up to 3500k or thereabouts but goes away after that and just leaves a slight whistle from the turbo which I would have said is normal.
Thanks!

Yeah I can log them tomorrow evening and post them up...the injector seals on injector closest the box needs to be done its not very bad but there is a sweat around it so I am going to do all 8 seals, I don't think this is causing my problem but at the same time I'd rather have it done. There is nothing else I can think that needs doing its fully serviced etc.

Cheers

Having another look at this I don't think there's anything wrong with your boost figures - I'd say your map is requesting a lot of boost for a stage 1 car - 22psi right through the revs is pretty high, I think that's more into stage 2 territory. Your turbo is only managing to give about 17psi above 6k rpm... how many miles are on the car? I expect turbo is just starting to get a bit tired, especially if it's had this map on for a while. Remember that a set boost figure is harder to maintain at higher revs as it has to flow more air to reach same pressure (as engine is rotating quicker > inlet valves are opening more frequently and venting off some of the pressure).

Your high levels of boost with few other mods would also go some way to explaining high CFs / cylinder temps - breathing mods to flow more cool air in and free flowing exhaust to let the heat out are why stage 2 boost / timing figures can be pushed further.

 

[ibizacupra]

this is a stage 1? no way?!?!

requests are high... and remember you can only see UP TO 2550mb (22.5psi) boost, and it may well be shooting past this and without a gauge you would be none the wise..

too much timing pull 9's up top!!!!!, and its not running much timing anyhow... = high egts
fueling check advised..

Hope its on VPOWER if not you should run it immediately... and unisettings back down the timing 4-5 degrees for safety

There is 70k on the car, I'm goin to get this sorted ASAP I really don't want to do any damage to the car!

We don't have vpower here I'm running it on maxol that seems to be the best available, sorry but I don't understand unisettings? Could you explain please? Ill log them this evening and post restlts!

 

[leon cupra r]

Unisettings can adjust timing across the board - you're pulling 9 degrees of timing correction meaning there's not much room until you hit the 12 maximum as I mentioned earlier.

If you retard timing with unisettings by 4 degrees and theoretically did exactly the same run under the exact same conditions your timing correction would be reduced to 5 degrees, leaving plenty of headroom to the 12 degrees max to allow for dodgy fuel / high intake temps / harder runs in higher gears etc etc

I only see 2550 mbar in the specified column, not actual?

 

[ibizacupra]

I only see 2550 mbar in the specified column, not actual?

yes, it was 0.010mb short of max sensor read<< My point to the OP, who no doubt does'nt know any better, is the sensor limit is all he can log, and if there's boost beyond 1.55bar it wont be logable.. Gauge will be required.

Anyhows. regardless of that the timing pull is excessive and fuel logs need to be seen

Question to me is why does it want to pull so much timing..
I would be pulling off the intake pipe off throttle body at this point and looking for oil dripping out, as I see this often where PCV breather system has split and excessive oil breathing occurs into charge pipes and the engine breathes its own oil, in copious amounts which ruins any octane of fueling and the det onset occurs... and CF's go very high.

Healthy LCRs do not ping that much on 13deg of timing.. they will support 20+degs when all is well more often than not.

I had the tb off last week to clean it there was no signs of excessive oil at all just your usual residue in the pipe work as I have no catch can.

Our petrol over here is really **** any tuner here will tell you that, it was defenitly mapped before it was imported so iv a feeling it was mapped on v power so this could be a part of my problem I suppose a run with octane booster and some logs could confirm this?

 

[LEE69]

octane booster wont do jack, only rob you of a few pounds it costs lol

 

[vagman2001]

octane booster wont do jack, only rob you of a few pounds it costs lol

I agree most octane boosters will but after a chat with a tuner today (same guy who maps rsmith's car) not all are the same he gave me a name of one to get that he swears by I can't remember the name of it right now but I will put it up when I find out.

Any thoughts?

Fuelling is not standard - you can see the 0.953 lambda up to 3k revs, at which point it drops to 0.875, so it's definitely been adjusted... Looks like you're hitting EGT protect at 5880revs in first log when it richens even more to 0.75ish. (5240revs in second run you can see it exceeding 920 and the 'richening factor' start to kick in in the next column along.

Your EGTs won't be helped by your timing pull - fuel will take a fixed amount of time to burn, the later the spark is (due to retarded timing) the more likely the fuel is to still be burning when the exhaust valves are starting to open...

Second log shows N75 duty is high to hold 1.2bar (17psi) and boost is still not hitting requests - Bill, is 95.3 the max duty it will run? Theoretically 100% would mean N75 is holding wastegate completely shut, i.e. your turbo is making as much boost as it possibly can at that RPM.

Your intake temperatures are also quite high - I imagine the order you have posted the logs is the order you did them? In which case your engine will have been quite hot and heat soaked by the third run if you did not do a cool off run inbetween... This would explain the 30degree starting temps, but I would have thought given today's reasonably cool temperature this might have dropped a little at lower revs when you first open the throttle and fresher air is started to be pulled through. I'm guessing you're on standard intercoolers?.... Bill am I right thinking 50 degree intake temps is getting a bit toasty even for a third run? That sort of intake temp will also not aid your timing pull situation...

Slightly off topic, but Bill.. Interesting you make the point of oil vapours in the intake, I've been suspecting I might have this issue - remember my map where timing has not been adjusted... well I've only been able to add about 3 degrees timing when weather was colder, now dropped back to 2.25, and it's starting to pull back at that running on Vpower... Being that the smoke from your smoke test just disappeared somewhere I'm thinking I might have a dodgy PCV system thats supplying plenty of oil vapour to the intake to stop me being able to run advanced timing!

Looks like your injectors are maxed out. I took your first log which shows injector on-time, the formula to convert that to injector duty cycle is (inj on time * engine RPM) / 1200. I've added a column showing that to your log below:

So your exhaust gas temp is too high, causing pre-detonation so the ECU detects this and tries to add more fuel to cool things down but it can't because the injectors are already running pretty much flat out just trying to keep the air/fuel ratio correct. That's not a recipe for good times.
