De-cat question..

Ha ha, was thinking of getting in touch with you about that thing manny.

If i got that GCC thing how benificial would it be to me?

Keeping in mind my TII is TOTALY stock right now save for an HKS panel filter. All i want to do at the moment is put on this exhaust and fit anything else that i would HAVE to fit in order to firstly, keep the engine healthy and producing optimum power, and secondly being able to pass an MOT.

It might be the difference between an MOT failure or not and ..... a blown engine or not.
However someone far better in the knowledge of these things will tell you the pro\'s and cons but to be honest i cant find anything negative about fitting one. Its all good.

The GCC is an electronic tuning component designed to add additional flexibility to the fuel tuning capabilities of the VPC, PFC F-CON or F-CON S. The GCC simply plugs into either the VPC or F-CON harness and allows the user to further adjust the air / fuel ratio at five specific rpm points. Each five points offer an adjustment range of 16% rich to 12% lean, in 2% increments, of the base value. Four different selectable rpm ranges allow maximum rpm level flexibility when tuning the fuel curve. The GCC will interpolate, or average between the rpm points of adjustment to ensure a smooth transition of fuel delivery throughout the RPM band.

Well i cant promise i\'ll take it but i\'m certainly interested.

When you have the time let me know a price for it posted to PA7 5ED and i\'ll go from there.

Thanks bud. :Thumbs-up

Blimey just do a search on ebay and see what these things are going for.

I have an HKS F-con piggyback maped to run with a bigger exhaust and FMIC plus other bits and bobs its good up to 300BHPish. Thats not fitted to the car yet though

I\'m going to be buying a Blitz dual something or other BOV very soon so maybe that will help out. I just have the standard Turbo II BOV and also standard air intake system with an HKS panel filter instaled.

I think i\'m going to wait and get this Blitz BOV, fit that then plug in the F-con which should make the car fuel properly, then fit a boost controler to control the high boost? and then fit the exhaust system. And finaly take it to Dasteck or something to get it all mapped up properly. Would that be a good course of action?

You won\'t be able to get 300bhp from a stock turbo, well you might be able to, but it won\'t last long! plus the injectors will max out before then anyhow lol

Just saying its capable of dealing with power up to 300BHP. Thats what i was told anyway. I dont really want anymore than 250-260BHP.

Thats ok then

just remember to port the wastegates!

pdtaylor18 · January 30, 2009, 09:53:07 PM

You will get that just by decat, filter and ECU with boost controller.

m1tch · January 30, 2009, 09:58:29 PM

Mines on 210 with decat, freeflowing (although not 3") exhaust and filters and a wastegate that doesn\'t seem to like to stay closed, so it boosts to 0.6 bar then drops to 0.4 bar lol

pdtaylor18 · January 30, 2009, 10:18:08 PM

Is that it !!! You can get an extra 30+ HP just by an exhaust and 20HP by the ECU alone let alone all the other mods. Think your car is not pushing the right HP me old matey.

Prof · January 30, 2009, 10:20:41 PM

I think in Mitch\'s case the exhaust is the problem - it isn\'t big enough so it\'s throttling the turbo, plus he doesn\'t have the FCD and is therefore subject to fuel cut

L18M · January 31, 2009, 12:29:33 AM

just out of interest.. if you use a piggyback f-con, do you still need a FCD?

Prof · January 31, 2009, 09:08:32 AM

Yes

And by way of eplanation - the stock ECU looks at the signal coming in on it\'s MAP sensor, and when it records 8.8 PSI or higher boost, it completely cuts fuel to the rear rotor. The FCON just allows you to alter the fuelling by changing the airflow meter signal to add/subtract a small amount of fuel. This means that any fuel cut you get will be in effect regardless of the FCON settings.

A chipped ECU actaully removes this piece of code in the ECU hence providing the FCD function, and will then supplies different maps to provide more fuel at the higher boost values.
