wats the different with or without the fuel regulator in stock engine? :hmmmm:
Stock engine have stock regulator, adding one that is adjustable is for tuning. If you have mod your car then you add, if not stock should be good enough....:biggrin:

When you're doing ECU tuning/reflash, fuel regulator is a good hardware to 'upscale' the whole map by just adjusting the fuel pressure. I think mine is around 3 bar too. Used to be 3.5 before ECU tuning and it was deemed too rich. I am running on stock Evo parts, nothing hardcore.

I've done some minor mods :
1. Drop in filter
2. Ev0 7 cam
3. BOV
4. Walbro Pump
5. Spark plugs

So do i need to add the adjustable regulator? :confused:

Better check with Ah Wah... cos by yr mod list now, you don't really need it. It's more of 'nice to have' rather than 'must have'.

Ya lo....must check with him le.... if its not necessary then i can save money for other things d...
Agree with Bro. stutzedward. Last time go to this shop they say put fuel regulator good for turbo. After fitted I don't feel any difference but was shocked fuel consumption went up. One tank lost 50km so after a while I had it removed.....:smokin:

Maybe the pressure was set too high bro, that's why higher FC.

I had mine installed when I chg to TD05. Worrying that it may run too lean before I had dyno tune done, so it was necessary. :)

Mine originally already TD-05, so is stock standard with no other mod. They adjust to 3 bar, I tried 3.5 and even back to 2 and 2.5 bar, but fuel consumption still bad. Take out use back OEM, fuel consumption back to previous normal.....hahhaha:biggrin:

Maybe your ECU had been reflashed before... if the setting is rich on ECU, a tad higher pressure than stock for the regulator will eat you more fuel. By the way, what is your FC? Mine is about 5.5-6.5km/L in city.

Nope, my ECU cannot be reflashed. My original one was the 200bhp model. It failed and I got a chop shop 220bhp one which was interchangeable between the 200 and 220bhp model. The RS 240bhp model cannot be used in my model.
This 220bhp model can add chip but mine was not done. Probably like you say it is already feeding 220bhp instead oh 200bhp....hahhahaha
Mine should be around there, 5.5-6.5km/L if fully town. Mixed with slight highway I used to get 7 to 7.5km/l

hi guys, need to know how low can it be if gti installed Eibach spring.
I am afraid it might be too low since stock spring is also low oredi.

Any comment from Gti sifu with Eibach spring?

Am asking on behalf of my fren in JB

Thanks
