Looks like good progress so far on the turbo setup. Since we both have 33's and 4:10's we'll have to do some et testing at the 1/4 mile 
. If you can crack the high 14's I would be impressed.
Funny what 350rwhp will do in a 2800lb car vs. a 6500lb Cruiser
!
100lbs=10hp approx

My truck is now running. Right now I have the truck set at 5psi until I get a W/B o2 on the truck. I was using the stock air box with the MAF mounted close to the turbo. I found out that the MAF does not like the turbulent air flow and it makes the truck run very rich. So for right now I am running a open element air filter. I plan on making a custom air filter box. Even with 5 psi the truck is alot faster. I will post pictures soon.

Did you adjust timing? Got any more pics?

Some night shots. When I make the new air filter box I will then run the BOV back to the inlet pipe. I still need to add the check valve
in.

Today I put the innovative wbo2 on my truck.
Idle 14.7-15.0
driving no boost 14.6-14.7
1/4 throttle with 5psi I am running 13.8-14.3
Full throttle I start out at 12.5 by 4,000rpm it is 11.8 and by 5,000rpm a/f is 10.8
I am concerned about the part throttle with boost only running 13.8-14.3 a/f.

how much driving time have you given the ECM to adjust? And what is the AR on the hot side?
Wow man, that looks really really really good! The wideband will really help when you start pushing more performance. If you would not mind much can you post your AFR's with the 5psi you have now, and then with the increments of psi you choose, whatever you choose, as you go up? I'm still trying to figure out if we can "tune the AFR's" by adding more boost; I'm trying to visualize the graph and the relationship (direct, inverse, linear, curved) between boost and AFR. In other words, it is pretty well confirmed that with approximately 6.5 psi of boost the 1FZFE will run really rich at WOT (10.8 AFR's or richer!) I'm wondering if we were to goto 7.5 psi would the AFR goto 11 something, then 8.5 psi to 12 perhaps? Or is the 1FZFE always gonna run crazy rich up to the point of exhausting the fuel pump or the fuel injectors' capacity? Since you're starting low and you have to go up some, it will help to have that data. Anyways, again, your setup looks awesome! Excellent Work.

So far every truck whether super charged of tuboi charged and running different amounts of boost with my MAF always comes in at 10.8 AFR at WOT. I honestly don't think you are going to be able to tune the AFR by modifying the amount of AIR.
I think you need to alter the FUEL and URD has what I would use if I ever get to that point. URD MAF Calibrator
also, what was the calculated load? At 25% throttle I doubt that you had much more than 40 to 60% calculated load, depending on grade of road. I'm not thinking that 13.8 is much to worry about depending on load. 14.3 does seem somewhat lean but again it depends on load. HTH>

The truck is running 10.8 only at the last 300-400 rpms.
Also my Fuel pressure regulator is not hooked up to a vacuum line. Your instructions said to leave it off. Should I hook it up with a boosted truck?
My plan is to run 10psi and monitor the a/f along the way.
Mike
you should leave that line capped off. Attaching it would set the truck up for a very lean condition initially if the ECM was reset and under boost the AFR would go more rich.
For comparison we will be seeing more data from a SC'd truck with the same wideband and using three smaller pulleys than what is supplied with them. He also has my MAF and is running near identical numbers that you and TurboCruiser have seen.

Rock on proyect and instalation ..
10 PSI .. ! wou ! maybe you have in your plans fuel pump/injectors upgrade ..

I got to drive it yesterday. Definately faster than my LX450 with stock 4:10's and 33's.... but at only 5 psi it would probably make a big difference in the hills. On the flats it wasn't eye opening.... but one certainly gets 100% performance of an n/a truck with only about 50-60% of throttle input.
I can't wait to feel what 10psi will be like and what kind of power it puts down!

Nice project. What are you using for fuel control? I noticed sombody posted about not being able to do much with the AFR just by playing with the AFM. In my experience, I agree. Are you planning on some sort of fuel supplement for your part throttle conditions?
I think 12.5-1 would probably be the richest you would need under any condition. I wonder if you could lower the fuel pressure and run a programable aditional injector controller. The fact that the FZJ's run rich at the top end under boosted conditions is somwhat puzzling. Most vehicles I have turbo'd have exactly the oppisite effect. Are you aware if anybody has had success with an Apexi AFC on the FZJ computer? That might allow you to richen the lower zones and lean the upper zones.
I know that battling the open/closed loop and transition period can be somwhat of a challenge. Good luck and keep us posted.

The OBDII trucks have an inherent problem with running rich. This is mainly due to the fact that the stock MAF sensor saturates at @ 25lbs of air. When saturated the ECM goes into limp mode, far different than open loop. MAS280 is running one of my MAF assemblies which so far nobody has saturated. This is why I'm suggesting the URD unit because as long as my MAF is providing consistent readings, right or wrong, you can use them as a baseline to adjust for proper AFR and variances do to air density shouldn't matter.
anymore updates on this?

I drive it every day, no problems. I will have the 10lbs spring in later this week.
Mike
That's great. What is your gas mileage?
I'm thinking it would be really sweet (minus gas prices, arggg) to have a totally stock/clean 80 for me to use as a Real Estate client vehicle and have a turbo under the hood to really get around town and make highway trips a blast.
