FPR problem? not 1:1?

[luizdiefenbach]

Well after I installed my FPR everything was allright, I didn't notice anything wrong with the car.
But I tried do run tha vacuum line direct from the manifold to the FPR and I had a surprise...
When I hit WOT the car is very slow and my hallmeter show that I am PIG rich.

Consider that:
1) I set the FPR for 43.5psi with vacuum hose disconected
2) When the FPR was connected trough FPR solenoid almost always the solenoid was closed (and the fuel pressure 43.5psi) even in cold starts...
3) I think that is no leak in my fuel system I double cheked everything and after shutoff the FP dont fall quickly, I holds a plenty of time...
4) I live in brazil and i bought the FPR here, and there are NO technical information of any kind about the product...

So what is happening with my car?
How can I be sure that my FPR is 1:1 ratio???
Should I try to run a hose direct from manifold to FPR again?
thanks for all the aswers...

these are links to really large pics.... so it cannot be displayed directly on the topic...

UPDATE: I has testing today the the datalogger I made for my 2G and I found that my TPS was reading only 96 when I WOT...
I tried to set things right but I get 1 whith TB closed and 99 with WOT now....
tomorrow I will test the car...
I couldnt make 0 when TB closed nor 100 when WOT, is there a problem with that or its normal such TPS readings?

thanks for ANY aswer and sorry again about my english (and for the big pictures)

That fpr *looks* like a vortech FMU, which is like a 10:1, 12:1, or even higher fuel pressure riser usually used with non-turbo to turbo conversions that retain stock ecu's.

whell my car is in tip top condition again...
I actually don't know what was wrong because I made many changes...
First I corrected TPS adjustment...
After that I change the plugs to BRP7ES (I was with BRP6ES)
I switched both AFPR... the one that was used on nitrous alky system with the EFI one (in the pictures...
I notice two complete oposites behavior from the AFPRs.... It appers that One have 1:1 ratio and one not....
The onde with odd ratio is now in the alky system (that has a pressure without vacuum/pressure signal) so its ok....
The car has drasticaly changed after those mods...


I was just forgetting: I bypassed the FPR solenoid... So straith manifold to AFPR vaccum line....
