Fuel Rail sensor

[matthewp1633]

Mr Teapot MAPed it in for me while he did my remap.

If you went from the standard 1600 bar to 2000 bar, you'd see a reduction in duration of 12% for the same fuel quantities but as teapot could have pushed 1750 bar on a standard sensor the duration reduction attributable to the sensor alone would be about 7%. I don't have the tables to hand but even on a standard map you could be looking at 28 to 30 degrees of injection, resulting in 2 degrees effective advance of timing. I think the impact would be greater than 5hp.

[QUOTE=nutron;2509899]That number came from a friend of mine and was passed in confidence to a member on a Facebook site who turned out to be very untrustworthy. Also the claimed outout from that individual is likely to be 5% lower and no where near my current achievements. Increased pressure is possible even on standard components but an R80 pump and change of lift pump are needed for full use on

There is an R80 pump and insignia injectors now fitted

Hi! What do you think of fitting a 2000bar sensor to stick firmware?
Would 5% increased fuel flow have any benefit to stock firmware with egr and dpf delete?

Well to be fair Karl knows his onions and if he says that a 2000 bar rail sensor would work then I would believe him as I am sure he has done the required testing. Just remember he is talking about the 2000 bar sensor not the 2200 bar one that I mention which does need mapping in or limp mode will happen, as he has said in the thread.

The injectors he has mentioned are from a 2.0 cdti INSIGNIA 160 bhp version with the part number he has listed and I understand they can be used without mapping and will give a power increase. However without mapping I was advised there could be cold start issues and rough tickover if the injectors are not mapped in but how bad I could not comment as mine were mapped in.

So YES there would be a benefit to fitting the 2000 Bar sensor and Insignia injectors with stock firmware.

Just noticed you've got 280bhp & 550nm from your Vectra?

What's your spec mate?

So here is the list:

GT22/56V welded to an Insignia exhaust manifold
2.0 cdti 160bhp Insignia Injectors
R80 fuel pump from a Alfa 2.4 jtd
Air box mod to the standard air box with standard air filter to maintain good filtration
Full EGR blank and delete with the cooler removed
Swirl Flap Blanked
Custom 3 inch downpipe with no pre cat
Straight through 2.5 exhaust with no main cat into twin tailpipes
2200 bar fuel rail sensor (mapped in)
80mm MAF (mapped in)
4 bar Map sensor (Mapped in)
550x185x63mm front mounted intercooler with 2.5 inch piping throughout
Teapot Remap with boost set at 2.5 bar

It is a long list but to be fair it has been done at a fraction of the cost you would expect for example I made the exhaust myself so the total cost was less than 100 pounds. The whole front mount set up was also less then 100 pounds.

The Turbo set up was second hand and from memory was about 200 pounds.

To be honest I am looking at making a custom exhaust manifold for a friend with the parts to make being about 100 pounds and a second hand GT 22/56V from an ML270 is about 120. To re-core the Turbo would be about 100 so a total cost of under 400. This set up would flow a great deal more Air than a Hybrid GT17/56 and be much more reliable with the capabilities of going higher.

Others have used more modern Turbos like the GTB22/60vklr as they spool much quicker and have ball bearings but they do cost £1500.

I wanted more power but I was unwilling to pay silly money.

I've worked it out for a GT2056, it'll cost around £800 for the 1.9 CDTi
