Jeff's MKIII picture/progress thread

[monster2j]

I recently got some time off from work, so i decided to get some things done before i have to go back. I bought today two spray cans of dupli color flat black vinyl and fabric/carpet paint. So i removed the carpet and find a bunch of dirty change, two screw drivers, and an adjustable wrench... The sound deadening wool underneath the carpet was really damp and smelled like crap. I removed all of the wool it was pretty heavy probably ten pounds worth. painted the carpet and while it was drying decided to remove all of the sound deadening tar from the floor boards. It weighed 48 pounds! The tar i removed in the back totaled 20 pounds. so if you add it all up with the wool i removed its around -78 pounds in sound deadening material so far, and i still havent taken it off where the back seat goes. probably be about 100lbs. total in sound deadening material.

Got some work done today on the car, removed the front and back crash bars. Im also thinking of designing and fabing in some smaller bars in its place, im also getting ready to fab and weld some triangular fender braces since no one seams to make them for our cars.

I highly recommend you to keep the front and rear crash bar. If you mount that bumper on and some DoucheBag backs up when you are parked in a spot, you won't have an intercooler anymore.

I highly recommend you to keep it, other members will as well.

 

[monster2j]

Im going to fabricate a lighter chromoly crash bar to go in its place, so i should be ok, but thanks for your concern.

I put the 440's back in today because it was running pig rich at idle and part throttle, im going to see how much fuel i can add at WOT with the SAFC before the FCD restricts it. ill also be posting up a video soon of some fly by's and some speedo pulls..

Do you have a stock 02 sensor? I just copied your style of resistors and 550s and installed a innovate wide band to watch my A/F and emulated the 02 signal. It drives around in the 14's until I hit boost then it hits the 9's. So maybe get a 02 signal and then tune the top end with your safc. The stock ecu can account for +30% fuel and the 550s are only 25% larger.

wait so do you think my O2 sensor might be bad, is that why its running so rich? also what do you mean by emulating the O2 signal?

 

[gurley0916]

Yes i think your 02 is bad if it is not correcting your air fuel mixtures. Emulating means that the unit can give out a normal narrow band output with the wideband sensor. Basically copying a 02 sensor signal based on what it is reading, while acting as a wideband with the other out put. There's two outputs. Im surprised you have a FCD in without a wideband...kinda scary to me, But you did have it taken to a dyno so I guess that could be piece of mind...

hmm i didnt know that, ill order an o2 today. Actually I do have a wide band but its an Uego so i dont think it has emulation capabilities like the Inovate or Zeitronics. When my car is cold at idle my wideband reads around +-15 A/F but what scares me is when the car is fully warmed up at idle it reads 17-18 A/F which just seams pretty lean.

 

[IBoughtASupra]

When the car is cold, it should be a little rich, not lean. 15 on a cold idle is weird and 17+ after warmed up is crazy, seems to lean but the Aristo ECU's are like that but not that lean.

I believe Gurley had a lean condition but it was just how the computer was running his 2JZ but I don't believe it was cold when it was happening. He can add more info to this himself.

 

[gurley0916]

Yes I had a lean condition at idle of 17/18's when i didnt have an 02 senor on my 440s and that sucked but with the 550's and the 02 sensor emulated it runs 12's when cold and 14s when warm.

cool, i hope this fixes the problem, thanks for your all your help guys!

 

[monster2j]

well just drove my car around the block and it stayed in the 14's, the true test will be on the way to school this afternoon. also we will see if the 440's can provide enough fuel for wot.

 

[monster2j]

Ok every thing was good, except im now hitting boost cut, and i have an fcd wtf?

 

[mk3tattoos]

How's it going jeff, are you still hitting fuel cut?

 

[monster2j]

I doing good, sorry ive been laggin on those 440's if you still want to trade for them i could ship them out tomorrow. Only thing is that you will need to switch all the bolts and restraint plates over from your stock one because i think i lost most of them.

I think the ecu was trying to compensate for the lean condition so much that the voltage was higher than the level 9 setting therefore causing boost cut. i put the 550's back in and every thing is fixed now, and i probably get another ten miles to the gallon from just putting a new o2 sensor in. now i just need to fix my alignment im literally going down the freeway cockeyed.

 

[mk3tattoos]

Good to hear everything is working, well almost everything.....you should do the laser alignment

I am still down to trade for the injectors! I got my paypal working and ordered a safc2 the other day as well

Hahaha Yeah, im planning on getting a four wheel alignment on her soon, after we trade. Nice you got the SafcII, with the 440cc injectors it will make tuning a breeze with the SafcII, you will probably be leaning the fuel mixture out instead of richening it. which is good because with my experience with the Fcd and Safc combo you can only lean the mixture out with the Safc you cant richen it or it will cause you to hit fuel cut.

Painted my valve cover and spark plug cover wrinkle black today. As i was taking these pictures to post up on here i noticed my accessory belt was partly off one of the pulleys wtf!
