Cant richen it up Crome with 1000cc injectors WTF!!!
Ive got a stock GSR bootom end with b16 head and GSR cams. PTE 1000cc injectors, walbro255. Holset HX35 stock map sensor. I was running a B20 but dropped in my GSR. now im tryin to get tuning done on it and no matter how much i richen it up in boost on crome it runs the exact same, mid 15's AFR and the plugs show the same. So WTF am i doing wrong?

fuel pressure is dead on at 45psi static pressure, and i do have a resisitor box wired in. It was working fine with the ostrich on my B20 that i just took out.

May be a dumb question, but are you saying the fuel pressure is 45psi at idle or at wide open throttle? It makes a little bit of a difference.

Re: (david@didrace.com)
static fuel pressure.....(at idle) is 45psi. and the full throttle fuel pressure regulator is a 1.1 increasing ratio fpr. So even at 6psi its at 51psi of fuel pressure. but i know thats not the problem, everything was working fine when i had the B20 in it. Could it be a problem with the ostrich?

Re: (a1320honda)
could be a bad wideband o2 sensor.......when they go bad they usually stay around 14.5-15:1.......
try dumping a **** load of fuel to see if the engine will stumble.....if it does then maybe your wideband had gone bad.....

Did you actually check fuel pressure at WOT or are you just assuming it's ok?

assumptions. the #1 cause of blown engines
try richening up in the low cam... maybe your ecu is not switching to the upper map. just a thought happened it to me once.

This gets my vote. I've seen it as well.

Re: (a1320honda)
are you doing it real time? try to do oldschool - burn - adjust fuel - burn - adjust fuel..
you're using crome pro right?
maybe youre adjusting in the wrong column.
try to richen the idle just to see if the program updates accordingly, if it does, try to datalog and see where exactly you're in in the boost maps.

Re: Cant richen it up Crome with 1000cc injectors WTF!!! (a1320honda)
Just noticed this thread is a wee bit old, so hopefully you figured out your problem...but in case not:
I had a similar issue where I couldnt get more than 360whp going (tuner kept saying I was out of injector cause no matter what he did it didnt change it)
turned out to be a partially clogged fuel filter. We replaced the filter and the car was now very rich (due to us trying to get it richer w/clogged filter). IMO its worth the few dollars for a new fuel filter...good luck.
