Engine
h23vtec 89mm bore. Im working with neptune rtp. Motor is running very rich idles like crap. Right now I have the stock injectors set at 240 and my new injector size set at 865cc. Overall fuel trim is at 22, Tps tip in trim is at -60, crank trim -49.9, post start at 0.

Now I know Im running rich cause for one I can tell by the smell of the exhaust air. I can also unplug the injectors for a couple sec and the motor will catch up then die. I've also noticed that my fuel pressure gage drops almost to zero after idling for a min. Please don't flame me for posting and prob not giving relevant information to help but feel free to ask me questions. I just don't understand how it can run rich with the values I've given it to work with.

Thanks
Bobby

Do yourself a favour and take the car to a dyno, otherwise you are going to was out your cylinders.

can u run stock injectors and stock ecu for a while? to break in the rings and get to a dyno at least?

that's a thought!..Well I have some new injectors that I have been trying to sell..I guess they wont be new anymore . I talked to hrtunning on neptunes forum and he says my overall fuel trim could possibly be to high. His advice was to start from zero and work my way up. Honestly I just wanna get this thing ready to take to Tony at T1.

James is right. With the Tip and cranking that much out, it looks like your overall is too much.
