What were your 02 read outs?
gpriceynissan said:Well, I dyno'd tonight--only got 160FT.LBS. torque though, and less HP. I have a crappy intake setup though, with a restrictive home depot elbow after the MAF...but anyway...my a/f ratio's were in the 15's...BAD.. all through the middle of the powerband. I tried hooking my fuel guage, but it was leaking, so I'll have to check that later. We tried upping fuel pressure to over 70 psi--no change!! I'm almost positive it is a fuel FLOW issue, in which case pressure has nothing to do with it. At first, it dyno'd at 140 tq., and then we bumped timing up...i'm not real sure how low it was cause I couldn't remember the timing procedure when I set it...and I set it at night and could see the marks real well...ANYWAY--got 20 torque across the board just from that. I may have more room to go too. This whole thing totally makes me want an e-manage and wideband to tune on the road and not have to set up dyno equipment.
You are running more than a little lean. You are running lean for a NA car, let alone a turbo car. Are you sure the AFC is hooked up correctly? If you are making changes on the afc without any results, something isn't working properly. I'd start there.gpriceynissan said:The regulator is stock--but modified for adjustability--it's fine. I don't get any hesitation, it's just a little lean--but that's a good idea of something to check...especially since NO ONE is chiming in. Guess cause not too many people have had a lean problem with 370's and a DE ecu and an S-afc set to +50%. Things that make you go HMMMM. Tonight I'm fixing my horn so I can honk at people who like my driving enough to honk at me, and I'll go over and clean all the engine grounds...maybe even add a couple. Usually wouldn't the starter not work if the engine ground was bad? Maybe just the injector grounds are bad. Man i talk a lot..i'm outta here.
