20v Revo SmS (303hp) problem

[rs200]

hy people

I have one problem with my revo sms ECU , or with engine...

well now I run:
revo sms ECU 303 hp
k26 turbo (same like SMS and MTM) turbo is perfect
S4 fuel pump
4bar FPR
but it have 3B injectors (304cc/3bar)
now I put AAN injectors (348 cc/3bar) like it have to be, but car don't run better.. they loose power at middle rpm and than on 5000rpm have huge kick of power

AAN injectors are tested , and work perfect.

how can it be? ECU are made for AAN , and was been on S4 lots of years, run perfect, but now don't to run perfect on my 200 20v with AAN injector?

they work good with 3b injectors, and I was thinking to put aan injector, maybe it will be better...

what can be a problem...

thanks

because you don't have the correct fuel map to run those injectors in that case. "More fuel" doesn't need to mean "more power" if the fuel/air ratio is wrong

this revo sms ECU are for AAN injector not for 3b.

with 3b work better than with AAN injector.

before than this ECU come to me it was on S4 (AAN) for a few years, and work perfect.

where is now problem?

very strange problem, not logical to me...

can somebody explain me where did I go wrong ?

[rs200]

can somebody HELP me ...?

please

are you using it in a 200 20vt turbo 3b ENGINE??

it is extrange yes

[Rocco]

if not...use the Vagcom or check the sensors of the engine .... always giving problems because they are too old...

[rs200]

thanks for help... but all sensors are ok , and half of them are new.. the old but good are: throttle position sensor and maf sensor..
they work fine...

can maybe be a problem with fuel pump? how much pressure (bar) have to be at idle ?

thanks

at idlle may 2.0bar or 2.5bar??

i measured it 2 times with a gauge in the fuel rail. one with 3B FPR and and the other with 7A FPR ...and both times the same. the the pressure only changed with WOT to the maximun of each FPR

[rs200]

hmm...

thanks , but I think... isn't 2 -2.5 bar a little bit low?

I must buy a gauge for fuel pressure... and I will...

Rocco thanks for info..
