First rolling road figures, low output? Fuelling probs?

Make sure they remove the manifold to replace the injector seats or the old threadlock falls down into the head.

Cool, cheers. Just waiting on the garage calling back with an estimate. Car is due 50,000 service now, already had cambelt and water pump changed back in March, oil and filter changed and sump cleaned out about 2 month back so don't need those. Asking for gearbox oil, fuel filter, spark plugs, injector seats and seals and brake fluid changed, and check the fuel pump, FPR, injectors and clean and reset throttle body. Looks like getting ARBs fitted will have to wait a bit longer

Slightly off topic, but if they're going to have to take the inlet manifold off anyway then they'll need a new gasket to put it back on right? If so, might I be as well (if I can afford it) getting something like a Newsouth Power Gasket or one of Bill's Phenolic gaskets to put on while they're at it? Do these really make any worthwhile difference?

Yeah I would

OK I'll see what the estimate is like and if I can afford it I'll speak to Bill or order the Newsouth one. Any idea which of those is better? Bills one sounds like it's about 2x as thick, presumably that means it works better?

 

[adam cupra 20vt]

I have no idea to be honest, the one I used was from abroad but I can't remember the name of it....may have been AMK Fabrications.

 

[ChrisGTL]

Phenolic ones get the vote over Newsouth ones from the techician @ AwesomeGTI.

Think he tried both, he is impressed with the Phenolic one he has on now. As you say, thicker = better for reducing heat.

 

[james walker]

Agreed, phenolic all the way

 

[8bit]

OK, if I can afford it then I'll do that. How easy is it for an amateur with very little experience working on cars to do? Starting to wonder if I could replace the gasket, injector seats and seals myself if there's not too much to it?

 

[adam cupra 20vt]

You need a special tool to replace the seats

 

[james walker]

Or a very big hex key.often need breaking out

OK, getting the fuel filter, spark plugs and injector seals changed next week, along with gearbox oil and brake fluid since they're overdue anyway. Was at a local meet last night and a couple of folk were surprised at the amount of fluid on the manifold around the injectors.

One of the guys had a scantool type thing and checked my long-term fuel trims (thanks CSD_19!), which were showing -7.8, altho no fault codes (think I read that it has to exceed +/-10 to throw a code?) which would suggest that its' leaning out for some reason. The ECU was reset the last time the car was logged, about 3 or 4 weeks ago so it's trimmed that to -7.8 in a fairly short space of time, and I haven't been thrashing the car since then.

I guess it could be leaning the mixture because it's losing fuel around the injectors, therefore it thinks its' running rich? If the filter, injector seals and spark plugs don't fix it then I guess the next step is a new FPR...

How you getting on with this Niall? any progress?

I had mine RR'd last weekend and my standard LCR showed 206 Hp, 202 lb/ft (184 Hp at the wheels).

The guy said this was strange as the 1.8T 20v he has tested usually hold the power. He recommended new plugs. According to the SH, these were done 15,000 miles ago (recommended change at 40,000) so they should have plenty of life in them.

Any thing I should be looking out for? Relatively new to the LCR and a bit of a novice when it comes to this. What are the OEM plugs for a 2005 LCR?

Any help on this would be greatly appreciated.

 

[8bit]

Alright Ben, well I got the above stuff done a couple of weeks ago but not had a chance to get it logged yet, both me and the guy who kindly does VAGCOM help for me have been too busy to get it together. Hopefully will have some results soon, I'll post here as soon as.

Remind me, did you get yours sorted in the end? Did you manage to install a silicone TIP?

I personally wouldnt leave plugs in for 40k on any car never mind a tuned lump like the 1.8t, youre best getting them swapped.. lots of info on here as which is best, think the model is NGK PFR7Q or something along those lines off top of my head

No I haven't got mine sorted yet mate, I've got the TIP installed, seemed to have made a bit of difference, seems more responsive, turbo quicker to spool up etc, but it's still dead in the higher revs and hasnt got as much kick low down as it used to...

Logged it today and it is still routing for the same 0.953 figure on requested lambda right through till 5-6k revs same as it was before

I've sent a PM off to Forge to see if they have any ideas and whether or not they think it is worth re-flashing the map incase it has corrupted or something, but obviously you dont have this luxury being on std map lol

Does yours feel any better after having everything sorted?

My long term fuel trims seem to be getting lower and lower, I've been seeing -7% similar to what you were getting... really want to get this sorted now! lol

Also my MAF figures in 3rd and above are still only peaking around 180, so even with the TIP it doesnt look like the engine wants as much air as it should be taking!

Keep us updated as soon as you get yours back on vagcom buddy

 

[8bit]

Yeah it does feel a bit better but then the weather's getting colder now so it could just as easily be down to that, will see tho. My next plan if it's not sorted yet will be the FPR...

 

[leon cupra r]

Hi Niall,

Hope all is well with you, it's been a while I know, but I'm back in an LCR! Got myself an '03 AMK running P-Torque stage 1 and from the little bits and bats of logging I've managed to do so far it looks like it's doing the same lean running as your motor was!

Glad I remembered you had this problem, as hopefully you will have a fix for it?

Here are my logs...

Hi mate, long time no speak sorry to hear your new car showing problems. Mine turnabout to be the thermostat. I discovered this by accident. Had block 001 logged for something else and noticed that the coolant temp (also on block 001) was showing we'll under 90, more like 70 - 75 even when the car was properly warmed up and temp gauge on the dash was showing 90 for ages.

Once I'd had that fixed I found the temps we're logging properly and the lambdas ran better higher up the range. Can you log block 001? Make sure the car has been driving for about 20 or 30 mins first so it's up to temp, if you see lower temps on that log than about 90 give or take a few then your thermo is likely goosed.

Let me know how you get on.
