so your saying your o2's at WOT are only .82. that's way to lean isn't it. .92 is what i've been aiming for. i'm already at -37 on my highs on my safc and have been slowly leaning it out but seems like my timing is not going up even when i lean it. i'll try -40 and run another log.
w/o a wideband it's almost impossible to know what fuel ratio that would be. If he used a wideband when he tuned and was aiming for like 12.5:1 he might be sitting at .82 on the narrow band. Could also be the O2 is dieing and just needs a replacement.

I can't really justify buying a wideband to only use it a few times. But I do have 2 buddies that own 3rd gen RX-7's. One running a HUGH 61-1 single turbo and one w/ stock twins running non-sequential. We are going to all go in at buy a wide band to cut our costs. Only way to truely know what your AFR is at.

.82 would be super lean if it was working correctly. On a few recent test runs the vac hosse on the fpr came off causing fuel pressure not to rise with boost. At 20-21 lbs of boost and a rich tune, it was at .88 volts with the hose disconnected. Took a while to find the casue of all my knock. O2 volts are worthless to tune by IMHO

Nice job on the [email protected] DSM. For a FWD that is pretty good considering the wheel spin you can hear in your video. I went [email protected] on that turbo and I know it has more in it. I'm still running a S-AFC and tuning was done with an AEM UEGO gauge on the street with no logging. My stock block also has 118k miles on it. I think with DSmlink and a fresh 6 bolt with Evo 8 pistons will put me in the mid to low 11's. Anyway good luck with your Fp.

I also just got finished installing my FP3052 last night. Even at 14psi, this thing PULLS! Pulls even harder than my T28 spiking 28psi and dropping to 23. Install was simpe and easy thanks to the thoughts of FP. The spool up is LOUD and the wastegate scares whoever is next to you. AWESOME turbo so far.
