Bought a revo stage 2 mapped ecu with immo deleted, and cel deleted ect... am told it is around 21-23psi. And the boost is hard when it comes in..!

 

Have 3' downpipe with decat coming, cold air Fed induction, recirc valve, and buying an enlarged t.i.p... I also bought today a nice ko3s with forge actuator...

 

But have read and been told I will need a 4 bar fuel reg to stop it running lean.. is this true? 

 

Advise welcomed blokes

Bought the turbo because of current turbine failure 

Yeah mate, revo 2 asks for a 4b fpr when u go in and get it

What car will I get one off mate? 

And what fuel pump do the vRS run? Is it strong enough?

Seems fine on mine mate, dunno revo do it lol

Eeerm not sure what it comes from ?

S4? Rs4?

Thats my starting guesses , i was told once but i forget these things :(

Lol. I will do a little digging now unless someone comes along and tells us :-)

 

• I'm sure I was told the other day on here what car they came from but not to bother but that was before I bought a revo stage 2 ecu :-D

Yes REVO stage 2 are mapped for a 4 bar fpr. They are std in Audi S4/RS4 and part number is 0280160575. They are a std bosch off the shelf part in most motor factors also like euro car parts.

Thank you mate... I will hunt one down now :-)

4bar fpr also in the 225bhp cars like s3 tt and cupra r

Would u not need a 4 bar pump? What does the stock octy pump kick out?

If the map specifies a 4-bar FPR, then it's probably a good idea to use one.

 

I've just taken my 4-bar reg off and replaced it with a standard 3-bar reg to match the standard pump and injectors. Will be tweaking the map later in the week, and if all is well, then my 4-bar reg will be up for grabs if you want it. Genuine Bosch/VAG 0280160575. Loads of them on eBay.

Actually no not needed although some folks change to keep a consistent pressure. The REVO map changes the fuel duty cycle of the injectors and in doing so utilises the 4bar fpr. I ran my REVO 2 map with std pump. REVO do not state the need so I did not change.

I just removed my 4bar fpr too. Back to 3bar. I have Shark stage 2 map now and running 4bar pump but std injectors and car runs much better as that is how it was mapped for.
