Ok. I am going to try to get the vgt to stay closed and run a log right now.

cool, I am home now so I can keep doing revisions as long as you are up to it. will check here for updates.
I noticed in your log some area where you were trying part throttle, it does seem smoother.
We may be getting some of the cut from fuel issues also. your o2 readings are weird. I hope your emulated narrowband data is okay. did you shield the signal wires with a ground wire traveling the length of your new wiring? If the ecu is getting really messed up fuel readings it will cut everything.

DAMN! big difference. VGT as before It boosted a lot better. Went towards 20 psi at first and then I tried again and it cut at about 15. Still felt a tad bit laggy, but was pretty strong.

I pulled over and put a zip tie on the mechanism to keep it closed.....YOU WERE RIGHT! That damn thing scared the crap outta me. It boosted so fast and it kept pulling HARD. I think I was heading to 20psi and I let off. No cut whatsoever. I tried to get it to cut and it wouldnt. I let off becasue it didnt seem like it was going to stop.

All I need is to get the last readiness flag to pass, and I will be on the road ready to do real full pulls.....

Looks way, way better now!
I think for the time being you should try an MBC on that WG actuator controling the VTG and make it so that it acts more like a 17-20 psi actuator.
Must be fun to finally feel it rip. It is definitely going to overboost and cut (according to logs it did) on that last file, maybe try the first one with the VTG disabled and i bet it will be really smooth.
once the VTG is under control we can really open this beast up. That spool is AWESOME

Explain my spool. I really dont have anything to compare it to other than my 4cyl setup. Looking at the logs it doesnt make any sense. What Psi did I hit? Give me the details! I am hella stoked now.
I am surprised it even reacted the way it did with the VGT being closed the whole time. That thing is supposed to close down really far, and I assumed it would be too small to do any good past where it is set now. I am confused, it didnt pull at all like it was running out of breath. I looked through the timing just to be sure, and there was hardly any pull either. I just knew it was going to pull a ton of timing. When the VGT is closed that far with that much boost....AGAIN...I assumed the EGT would be rediculous. I guess we will have to see what is going to happen when I am finally able to rev it out.
Same readiness flag as the first page still NO-GO.

You peaked around 26 psi (over the MAP limit so i cant see) and it probably would have kept climbing really high had you not lifted. This is a by product of the 95% duty cycle on the n75 with a 13-14lb spring like you run on your external gate.
you had 10 psi at 3500, 20 at 4000 with basically no timing, so spool will get better. That spool is inline with GT based twin kits.
Next order of business for you is a MAF and VTG control. We are on the right track for sure. You ECU isnt receiving very smooth data from your wideband. what setting do you have in your LC-1? I will grab a screen shot of mine for you tomorrow.

It happenned so fast. I basically turned the corner to my street in second gear, waited for the rpms to drop really low, slowly peddled it, lugged it until it it boosted and it just boosted and got away from me.
We are definately on the right track. Thank you very much!
The wideband isnt hooked up yet. I havent updated the firmware yet. I will try and do it tomorrow while I am at work.

so what is feeding o2 data? because the numbers are all over the place with no rhyme or reason.

Stock o2, with feed going to both inputs.

ewww...ohhh...
no good. we gotta get that fixed and it will behave way better. the lc1 has dual narrowband outputs. it really does a buetiful job. look in the first 4 run compare excel file I posted, review your 3 and then look at mine. the car really behaves like it has two sensors. yours is going nuts and cant possibly be helping.
just goes to show you how much better this thing will get.

I Updated the firmware on my Lc-1 to the 1.2 version. Hopefully this fixes the 8 flash error. I also changed the analog output #2 to match #1. Hopefully this will be all that is needed to get it to work.
I would like to see how you have yours set up.
