under hood fuel filter got replaced with a brand new integra one during the swap, in-take fuel filter I have not touched.

 

how are your afr's the rest of the time?

 

Cruising its in the low-mid 14's, every once in a while jumps over to lean (I've been told thats normal)

Idle is in mid 14's, every once in a while jumps over to lean (again, I've been told thats correct), WOT below 5700RPM is a steady 13.8-14.0 in any gear.

 

i guess i have a hard time believe that it could not keep up with only 100k on it and not really need to much more fuel but i guess the logic is there. walboro time or find someone who bought a walboro and is selling a cheap stocker.... like me i have a fuel pump out of my 95 EX coupe

 

Yea, I ended up ordering a Walbro 255 today along with a B+M FPR and a VAFC....

Waiting to hear back from a member on these boards about some 550cc RC's that I want.

 

I just looked up the fuel pump on partsamerica and theat the 92 cx pump is the same as the 94-01 tegs....

 

yes, a NEW pump may be the same part, but my stocker may be a different part number than the integra.

Kinda like how the D16Z6 headgasket and the D16Y8 headgasket are now the same part and part number because they both work for the same application, but one was different from the other back when they came out.

 

damnit you shoulda bought my pump then id have an extra 10 bucks for some pizza tonight

 

I’m not very good at this stuff but is you have chanced your exhaust system. You are now flowing more air into your engine. You are using a stock ecm It dose not know about the change and is still using the same fuel maps. So same fuel + more air = lean. At lower rpms, cursing the system is using short/long term fuel trim and trimming you to 14.7 ish.

I can also see a misfire causing a lean condition. Ok I will probably get burned now by the og's.

 

Header is still stock, the rest is 2.25 piping.

the intake should have NO effect on how lean/rich I'm running since honda's are MAP cars, the ECU should be taking care of it.
