I HAVE A TYPE R SET UP BUT IT IS A FULL 18C1 BUT WITH THE TYPE R INTERNALS. JDM TYPE R .85 OVER BORE , SKUNK 2 MANIFOLD , AEM FUEL RAIL W/ ADJUSTABLE FUEL PRESSURE REGULATOR AND GAUGE (FUEL PRESSURE IS AT 40 PSI WITH VAC LINE ON, 50 SOMETHING WITH THE VAC LINE OFF) DC HEADER, 2.25 PIPING WITH HKS SUPER DRAGGER EXHAUST, MSD SS BLASTER W/ MSD 6AL , NGK 8 SPARK PLUG WIRE, RC 310CC SL INJECTORS, HOLLY INTANK 195 FUEL UMP, AIR/FUEL GAUGE, P73 JUN ECU (5000 VTEC, 9600 REV LIMIT). AFTER I PUT THE JUN ECU IN I STRATED TO RUN REALLY RICH THEN A WEEK LATER I PUT RC 310 INJECTORS IN AND IT IS BEYOND RICH LAST NIGHT MY 02 WENT OUT CODE CEL 1 OBD1, AND MY AIR FUEL GAUGE IS LIKE STUCK AT SUPR RICH WONT BUDGE. ALSO WHEN I GOT ON THE FREEWAY I PUCHED IT AND IT SMOKED. THEN THIS MORNING I CHECKED THE BACK OF MY CAR IT HAD BLACK SPOTS ALL OVER AND ON THE FLOOR THERE WAS BLACK MARKS ON THE FLOOR THIS IS WHILE IT IS WARMING UP.
WOULD MY O2 SENSOR BEING OUT CAUSE MY CAR TO RUN SUPER RICH ? HELP ME OUT (((((((( SORRRRRRRRRRY FOR THE CAPS I ALWAYS TYPE WITH CAPS)))))))))))) <U></U>

 

Take the 310's out and put the stock injectors back in. Drop your fuel pressure to 45psi with the vacumme line disconnected.

Get some real engine management. And turn off your CAPS lock.

 

and make sure the ECU isn't in limp mode as well....

 

if i take the 310's out and drop the fuel pressure to 45 wouldn't i lose power. stock pressure with stock injectors is like 50+... after i put the 310's in i got alot faster.

 

Your ecu has to be tuned to run 310 injectors..Is it? If its meant to run stock injectors then its gonna run REALLY rich with 310's.

 

replace all that fuel crap with the stock stuff. go back to the stock ecu. you have no real need for any of that.

 

ditch the pump,injectors,fpr,a/f gauge and ecu. Install all of the stock stuff in place of that. Then have your ecu shipped with crome or similar and have the damn thing tuned. The gains will be very impressive and it is the only way to insure the safety of your engine

I'm not sure how you are gauging your "fastness", but there are some flaws with your arguments..

What I'm getting from your descriptions is an attempted "Poor mans ITR". You have a 'C1' head on a 'C1' block with 'C3/5' pistons and rods. I'm still unclear about the camshafts you are using (C1, Cx, or something else); that will make a big difference in your approach to tuning this piece.

What cams are you using?
