You guys..... meanwhile back at the Badger Cave.....
Minor update... had the front tracking checked this morning as I noticed my low mileage front tyres had worn badly on the outside edge... was toeing in a bit so thats now sorted...
Grabbed a bit of time during lunch to fit my TFSI coil packs... (07K 905 715 F)
They are longer than 20v coils with a slightly thicker top too...
I re-gapped the plugs to 0.85mm... 0.5mm more than std and 0.15mm more than the 0.7mm I normally do for remapped engines... everywhere I read suggest using a gap of 1mm... I haven't for a couple of reasons... 1).. I wasn't running the car on the dyno to see what worked and what didn't and 2)... I need to put the std packs back in for when I take the car over to get them changed under the recent recall... so I played it safe until I have got my new packs and get the car back on the dyno...
Anyhoo... you can see the difference in height between the TFSI and 20v coils here...
...and all fitted...
Now I know the more eagle eyed ones of you will have noticed I am not using adaptors... a couple of reasons for this... they aren't ready yet... and I noticed when fitting mine that the coil leans over towards the back of the engine...
Not sure why but they all do it... it may be because of the position of the cam cover... i.e. there could be some movement on the studs and I have it too far forward or something... I don't know but they are in pretty solid... not having seen a set of adaptors from A N Other manufacturer in the flesh then I don't know how loose a fit they are as you can see clearly that the rubber seal is in the cam cover hole so is holding the coil in but the little tangs either side (20v coils have a single one) are proud of the hole so the coil 'could' rotate... what this is like on the other variations of TFSI coil pack I don't know but I think I will see what can be done to counter this issue with the adaptors Bill is looking into..
So... seeing as I haven't run the car on the dyno I can't give any info on any power improvements (if there are indeed any to be had) but I can say that the engine certainly feels smoother on idle and part throttle feel is improved... I have also done a couple of stabs at full throttle and no misfires...
I would say that this and the earth mods I have done have certainly improved the feel of the engine on idle and general drivability under no load conditions... how much of an affect it has had in terms of power I don't know... I will of course try and sort some comparisons out when I get a chance but I still have some tweaks to do to the mapping (as neither of us have had time to do anything more with it) and I still have a coolant leak to find/fix...
This mod is also supposed to improve fuel economy too... will see how that goes but not promising anything LOL!!....
One last update... after the agro I have had with some prize tw@t on eBay over the AEB manifold I bought before Christmas I ended up buying another from eBay and it arrived this week... w00t!
...so at some point I will be looking at making an inlet manifold...
Next on the cards will be relocating the battery to the boot, fitting the WMI (finally) and reworking the charge pipes as I am not happy with them currently... not sure exactly what I am going to do but once the battery is out the way I will decide then...
I also plan to replace the coil pack wiring loom too... this can be bought quite cheaply and seeing as most of my plugs are broken and I 'repaired' the cracked loom a couple of years ago it makes sense to do...
