rtek 2.1 with 720 +1000cc good enough for bnr stg 4?
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

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

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
