Mini-me swap question. Code 43?

[96scD16]

I just completed my D15 to y8 vtec head swap in my 88 hatch. The swap went perfect all the wiring info I got was correct, but the car keeps setting a code 43 fuel system code. The ecu I am using came from an old integra LS, the injectors are from a 92 prelude, and I am activating vtec from the shift light off my Autometer tach. The O2 sensor is from my old DX. The car is running great, good power. If you didnt see the light, you wouldnt know there was a problem. What could it be?

LS ecu and Prelude injectors on a D15...probably running rich would be my guess. Exactly what ecu are you using, PM7, PR4???

werent the old lude injectors peak-n-hold whereas the civic/teg injectors are saturated?

Yes but he's got an 88 Civic which also came stock with p&h injectors so there should be a resistor box already there. Anyways the car runs so that can't be the main issue. I'm thinking that an Integra ecu (mapped for larger displacement than 1.5 liters) pushing injectors that could well be between 270-310cc for the Prelude, has got to be running way too rich thus fuel system code. That is also bad for the motor when it gets taht rich it will wash the oil off the cylinder walls and eventually thin out the oil in the pan. Just something to look into, I can't guarantee that is your problem though.

quick ? hopefully someone can help me out got an 89 crx si about to do a mini swap with a d16y8 only have the head&valve cover no wires ecu or solenoid dont know much about cars but i do have freinds who do just want some second opinions....whats the right parts that i need????
