the car at first idled like a cam'd v8 so i adjusted the fuel pressure and got it back to normal...but now the car won't rev past 4k rpms...and if i take it to 4k rpms it back fires real bad and won't go any higher. it's a b18b with a t3/t4 57trim, dsm blue top injectors and a base map off of xenocrons website. slos13 burned the chip for me and b16crxt chipped it for me. i tried adjusting the fuel pressure more and the idle control screw and nothing worked

 

could be a bad burn or bad soldering. Got any CELS?

 

no CEL's at all

 

check the wiring for the restor box

 

everything for the injectors is good...my last motor ran perfect with the resistor box, injector clips and everything

 

this is the basemap from xenocron
B18b, P75, 450's, T3/T4 hybrid, Closed loop is enabled, 2.5" crappy exhaust, intercooled, dyno'd at 213 and 200ft.lbs. at 9-10 psi. This is slightly tuned with much room for improvement.

 

didnt you say you are running obd-1 injectors now? They dont use the resistor box. You need to do somethign like I did to get rid of it.

 

i'm running dsm blue tops man

 

are the fuel pressures the same on your car and the one the other tune was for?

 

i want to make sure it runs right now before i take it to the tuner nd they say my car is f00ked and i need to go fix it before i come back

no comprendo !

 

robbie with the black civic turbo...his car wasn't right so they pulled it off the dyno and told him to fix it then come back

 

oh o. who's gonna tune?

 

RLZ...well robbie told me they did that to him lol

 

i got a base map from them once and it was crap car wouldnt start it was spitting out gas while tryin to crank it had to make one myself ... thats prob it!.. make urself a new map try again

 

definatly sounds like an ECU problem, it sounds like she's running in limp mode dude.

I dont know anything about socketing ECU's but I believe theres more to socketing a p74 than just putting in a socket

 

my car wouldnt even idle with my base map. Same situation as you.. where I got a basemap that was exactly for my setup.

I'd throw in a friends ECU and try that same basemap.. Otherwise, it's pointless to scramble for answers when you turning consists of adjusting a fuel pressure regulator. *shrug*

 

I don't see why people with goals of only 250-350 whp use adjustabe fuel pressure regulators anyway. Hell the DSM injectors are pushing it at 300whp. I'd just leave the fuel pressure at the stk PSI dude. I think like 42psi but don't hold me to it. I've been painting all morning so I may be getting my air pressure psi on the spray gun mixed up with the fuel pressure psi.

 

i'm putting everything back stock on it tonight and seeing if it will run better. maybe it's just my fuel set up

 

does it only rev to 4k wiht your car at a stop, if so its launch control. IF it only revs to 4k all the time and runs like **** its either a bad burn or a shitty chip job on the ecu.

 

i hope you still have the chip that came with that p74.

 

The problem is not the car.... Your trying to run a car off a BASE MAP... if it idles then your good... just check for leaks CEL's and the normal things. Don’t try to drive the car on it, you run the risk of screwing something up big time

how can i tell if thats wht it really is? and it won't go past 4K rpms even if i try to drive it

Did you drive it though? Only way to find out is if you drive it and try to go past 4k.

 

just making sure, I'm worried about the socked job
