just like title says i currently have a rtek 1.8 and its leaning out pretty bad on anything past 6psi . i have a walbro and stock FPR . s4 t2 motor stock ports . car made some how 292 on accident on 14psi lol . so im not driving the car anymore till i get this sorted out . let me know wat u guys think . cause i plan to get the 2.1 .

 

The first two things I'd check, is it really 6 PSI, and is it really lean (wideband working correctly).

Lean at 6psi on a stock port and all that injector says there is something very wrong with the car, or the measurements.

 

if its not 100 degrees today im gonna take it all apart again . injectors are 2 weeks old tlc perfomance ones . all new fuel lines etc .

 

its not the wideband cause i can feel it driving the car . i dont even go into full boost in 4th gear anymore im scared of it just leaning out .

 

2.1 has datalogging so you could see what is wrong w/ your setup.

 

I had 1000's on my Stage 3 BNR and I had them maxed out on Duty cycle.

 

ahh so 1200s? or 1600 to make my life easy? idk wat esle to check everythings hooked up right . i know my fuel pressure is good because i felt a diffrence when i changed the pump. now for these junk injector brand i got idk .

 

Are you sure you have the injector impedance matched?

 

injector resitor box removed these are high impendence injectors . they were fine the first week or 2 . now i think one of them is bad. im gonna take them out tommarow and see wats up . either way im gonna change them

 

ok i figured out one of the injecters were junk . so i want todo the 1000cc all around . if any 1 has advice thinks its ok to do let me know i plan on ordering this weekend

 

Seems like a lot of injector for a stock motor, but I'll let some other guys chime in here.

 

I accidently saw 7 lbs(remember I'm trying to keep it under 5 lbs during break in) and my afr's were 10.9 - 11.5. and I doen't even know what kind of fuel pump that I have, I think it's a Denso.

How much more than my T04e does that BNR stage 4 blow?

 

no idea but it most likely does flow more considering myne is just a hybrid . so would like to know if the rtek can handle 4x1000cc injectors

 

I'm told it(2.1) can, you just have to compensate with adjustments. It's not as easy as it sounds if you do a thorough job of it.

 

well ill do 1000 secandarys then . now for primarys im trying to figure out

 

dude im sure you'll be good with 750 primaries. maybe even 550's. my buddy was running a T66 precision turbo with cleaned ports on his fd with his stock primaries and 1300 secondaries. so you really dont have to go too big with primaries. especially for a stock port engine.

 

how about the glse injectors the ones that are 600cc or something? im ordering the 1000cc tommarow .

 

if i remember correctly the gsl-se injectors are 720's?? someone needs to confirm but i think thats wut they r. hmmm

 

gsl-se injectors are 680cc. You can use them on the 720 primary settings, but your mixtures will be 6% leaner at idle and under vacuum/low RPM boost. I would suggest 720cc or 750cc to prevent a ton of tuning the vacuum cells. It's not easy to datalog those areas of the map.

720/1000 may be a little short for ~350 whp. Don't increase primary size; increase secondaries to something like 1200c if you're worried about it. That's about the largest injector controllable on an Rtek 2.x.

 

Dont forget that we don't recommend using injectors more than two "steps" apart.

 

well im getting a deal on 1000cc i seen people do 350 + on 1000 secondarys . im gonna be getting a meth kit too in coupe weeks . i want to make 320-350 no more . im scared of the rear plate cracking

 

Thats pushing the utter limits of what rtek can handle, at that range the vaf is maxed out.

 

lol damm . so then should i limit it to 300whp saftly ? im not looking too boost more than 16psi or so . i will be leaving it btween 10-14 psi . i just want it to last till winter when i get a real standalone and redo my motor

 

yes, i am currently running 550cc and 1000cc injectors with a bnr stage 4. it was running great.....until the ecu took a dump lol. i am running resistors for the injectors

 

new ecu will be back next week and i have a tune date on the 31st so ill let you guys know how it is
