Re: Running Lean, nearly stock, wtf.
 

I'll be getting my AFC on monday so I can richen things up a bit and install my fuel pump whenever the ---- I get my FPR.

Definatly not, I'm using a OBD1 PR4 ECU. (1993 Integra LS ECU)

Re: Running Lean, nearly stock, wtf.
 

FPR arrives Friday, already have the pump.

Re: Running Lean, nearly stock, wtf.
 

i still think there is something else wrong if you are using the ecu that is for the engine. all you will be doing is covering a problem and not fixing anything.

i cant imagine there would be a difference, but i would do some research on the fuel pump and see if a cx pump is different than the reast of them

Re: Running Lean, nearly stock, wtf.
 

CURRENT part numbers come up the same as DX/LX/ and integra pumps.

HOWEVER, the part numbers come up the same for D16Z6 and D16Y8 headgasket, but they were different parts, with different specs before the 'merger'

I suspect this is the case again, with the car being a 92 and pre-wired for everything, and used D15B2 *IIRC, the old 4 valver* pistons, They may still have been using the old school pumps as a carry over like the pistons. A member of another forum I'm on basically said flat out "The stock pump out of a 92 will not support that motor" and the fact that it runs out of steam and go lean RIGHT where the CX motor basically red lines makes me think this is true. Regardless I needed the pump and FPR for when I boost, so I don't mind if this doesn't fix the problem, I'd be annoyed granted, but its still money well spent IMO.

ALSO, as mentioned, I guess the stock ECU cannot compensate for a basic intake, so this may also be an issue.

the fuel pump and fpr are fine, i just wouldnt use an afc to get it richer when tuning isnt the problem. i would look to a mechanical problem more than tuning

Re: Running Lean, nearly stock, wtf.
 

Yeah you clearly have a problem that you will want to address before adding things that will mask the problem. Be happy that you found this issue before you started adding parts.

Re: Running Lean, nearly stock, wtf.
 

I'm ditching the AFC in favor of a chipped ECU after all. I suspect mechanical problem also, but I don't have a stock air box to test with to rule out that variable :(. I also suspect that with 115K miles on the stock fuel pump that was fed City gas all its life that its probably on its last leg anyways.

Re: Running Lean, nearly stock, wtf.
 

Stock airbox, CAI, filter on a stick, or nothing at all just naked TB, will do exactly NOTHING to change your tune.

Reread what Cray said. Fix your mechanical problem before you start throwing parts at the car.

Re: Running Lean, nearly stock, wtf.
 

I just went back and saw ghetto turbo correct himself on the airbox thing, My bad.

I DO have new plugs and wires to throw on the car along with the FPR, fuel pressure gauge, and Walbro

Again, I have no problem 'throwing parts at the car' because these are parts it needs for my goals anyways, and MAY be part of the problem.

Sat morning I will be installing everything, I'll see how it comes out.

Fixing my exhaust leak droped the WOT from 16.8 to 16.0. (if I didn't already mention)

Re: Running Lean, nearly stock, wtf.
 

If the FPR is anything other than a large exit B series unit then it is not only a waste of money but a liability.

Fixing your exhaust leak changed the way your wideband reads, not the way your car runs.
