TDC stands for Top Dead Centre. Its when the number 1 piston is at the very top of is compression stroke. Its normally set with locking tools that hold the cam sprocket and crank sprocket in the exact position which is identified by markings on the sprockets etc.

By setting TDC you can ensure the cam and the crank stay in sync when the cambelt is removed for example. In the case of the TFSI I'm assuming the injector cycle is related to this too, hence the need for it to be set for the fuel pump to sync in properly??? (Slightly out of my depth now

)

Can't wait for a software update

- i still dont understand how there can be a difference with a standard map..

can you explain?

I can only assume that he's no longer getting fuel cut-off at what ever revs it was - IIRC Harry was suffering quite a stutter/power loss at high revs.

Basically speaking, at the top end of the rev range the map is calling for fuel that the OEM pump just simply cannot deliver which is what is comonly known as 'fuel cut'. The new pump internals overcome this problem by being able to provide the requested fuel and will have the added benefit of increasing the potential from the TFSI especially once the likes of REVO have been allowed to play around with the settings.

For now I'm guessing that Harry is experiencing a 'smoother' delivery of power but I'm sure he'll be along and tell us exactly what the current benefits are.

So the current map already over-stretches the fuel pump?.. i thought it was wound-back so it doesnt?

or is it a case of a setting on the select-plus stuff

RevoKev · 23-01-2008, 10:41

The current map gives you more than enough adjustment to play with the car in differing conditions with different hardware on there. A Select Plus isn't a toy it's a tuning tool, thus why running 9 9 9 isn't always the best idea!

Depending on the conditions if you try to run the higher settings without a fuel pump you can suffer from fuel cut.
So basically with the pump on you can maximise the settings to suit. We're still interested to have a play with a car that has one on and see whether a stage2+ is warranted!

Only Harry has his fitted atm, hopefully in the next few days one or two more cars will be ready

Will be in touch

In fairness though Kev, most mapped cars have suffered fuel cut in some form or another irrespective of what settings they are running and that goes for other tuning companies too so it's not restricted to REVO.

Excellent, a vollunteer

Not this week I'm afraid.

cheezemonkhai · 23-01-2008, 14:23

Question is does the volume go up to 11?

Makefish · 25-01-2008, 19:24

Mines in with a little help from my 'friends', although who needs a friend that locks you out of your house?

First impressions are awesome but will give it a few days before we pass judgement

Oi, Mr Fish. What a very short memory you have. That person was running you around trying to find a 18mm extra long socket at 4:30.

Makefish · 27-01-2008, 11:52

Well after a 500 mile trip yesterday on roads ranging from fast motorways to sweeping A & B Roads with a few hairpins thrown in for good measure I can safely say that the pump had a damn good workout yesterday and mightily impressive it is too

. Car revs freely through the rev range and generally feels more responsive with no hint whatsoever of 'fuel cut'.

So far so good

Tom_vRS · 27-01-2008, 12:22

Good stuff Steve!!

Its a shame Harry doesn't seem to be having such a great experience... god his car stank of fuel last night

**VRStu** · 27-01-2008, 19:52

You never know after sorting everyone else out I might even be able to find time to fit my own

You had the time yesterday to fit it but decided on fettling with another project!

True I did, but where was my assistance?

In your own words 'it's definately a two man job'.

You've only got to ask!

**VRStu** · 27-01-2008, 23:16

You were at the C&F - Ask I'll I like but you would have still been at the C&F.

Hedge · 27-01-2008, 23:26

I'll give you a hand if you want Stu just keep the front door keys in your pocket this time.
