can someone help a tuning newb? i would take it to psi but i dont wanna pay for a dyno tune then in a couple months get new injectors and have to pay for it all over again:/ i am having serious boost withdrawls ...

ok so if 13.5 a/f is too lean under boost what would optimum be??? should i use the tracking function ,the low mid high user tunes or the ve table to tune with??? what should i watch out for and what is "DANGER LEAN"??? and what is way too rich???
I had zero luck with the tracking function, it was way too slow IMO and not very solid. Get your tune dialed in with the user tunes first, VE table is only for fine tuning later. The load values set in the menu determine when the low/mid/high user tunes kick in. Generally speaking, anything with very little load, mainly idle, will be adjusted with the low, mid is most anything between off idle and 0 PSIG, and high is anything in boost. Do you have your vf hooked up to your aux input? If you don't you should, that's the only good way to get your low load drivability tuned in.
thanks 
yeah vf to aux 1
W/O O2 Narrowband input to the 88 ECU (which I did to force ECU to open loop to tune) upon a cold startup My VF Signal reads 0.00. After engine reaches operating temperature (and passes 175 degrees or so) and the power is cycled (Engine turned off, ECU power reset via Key Off for at least 7+ seconds, then engine restarted) THEN the VF Signal will read between 1.95 and @ most 2.05,
is this gonna be a problem???

on another note i havent hit boost since i havent tuned anything ... should i richen the high tune just to be sure i wont run too lean???
vf isn't actually going to mean anything if the o2 is disconnected, because it functions based on the o2 feedback. It has no way of knowing how the engine is running a/f ratio wise without the o2 feedback. Even if the o2 was connected, you should disregard vf readings until the engine is fully warmed up(176 deg), as that is the only time it will be accurate. I assume you are trying to use part throttle tracking if you have the o2 disconnected. Like I said, personally I found the tracking to be way too slow (both part throttle and wot tracking) but if it works for you that is great. It wouldn't hurt to make sure the tune is slightly rich to start out with, also make sure you run off stock waste gate pressure to begin with (lowest boost possible). Are you running the boost control solenoid or using some other form of boost control?
the reason i disconnected the o2 sensor is i was told i would be fighting the ecu the whole time i am tuning
how rich is a good starting place???
my boost solenoid is in my center console until i get the rest of this thing figgured out

I did all my part throttle tuning with the o2 plugged in. Part throttle tuning and full throttle tuning are two different ball games. For part throttle, the goal is to get vf to read 2-3v under almost all load and speed conditions (minus full throttle). The only reason you would be fighting the ECU is if you were aiming for an A/F ratio other than 14.7 under cruise or part throttle. The ECU is always going to try to hit 14.7 when warmed up and cruising, so if you are aiming for something other than that A/F ratio, then yes you will be fighting the ECU, but really, there is no reason to do that.
There are some features such as lean cruise etc in the maft pro but those features wont work properly unless you have the o2 disconnected and are running part throttle tracking. You really need some sort of auto correction (the stock ecu does this, the maft pro can do this with PTT) because your tune isn't going to be 100% perfect under all conditions, so the ECU needs to be able to fine tune as you drive.
Bottom line is
If you want all the extra features of the maft like lean cruise you need to disconnect the o2 and run part throttle tracking
If you want a stock running car with WOT tunability, leave the o2 plugged in and tune your vf's for part throttle.
Like i was saying earlier, part throttle and wot are two different things. Once you go over about 75% throttle the ecu is driven into open loop (ignoring the narrow band) making it easy to tune- you aren't going to be fighting the ecu at all. At this point simply tune with a/f ratios, vf doesn't mean anything at WOT.
Since with everything at 0 the tune should be basically stock, I would probably add about 5% to the main scale to begin with, and watch your wide band carefully to make sure it is going rich as it builds boost and stays rich. The more fuel you add the more likely you are to hit fuel cut, but once you know that you are rich enough you can slowly pull back. If you watch your frequency out data ( i think that's what it is listed as) the closer you get to approximately 1500hz the closer you get to fuel cut, apparently around 1500 is where you will hit fc depending on a number of factors.
Sorry that was so long/ i probably covered a lot you already knew but i just wanted to make sure i laid most of it out. I probably missed some things too so go easy on me.

ok when i made my downpipe i didnt put the stock o2 sensor back in so can i feed the narrow band out wire from my lambda lc1 into the o2 wire on my tccs??? will that work??
i tried tuning a bit
set my mid at -1 acrost the board (now runs at about 11.5 to 12 on afr during no boost accel)
initially set high at 5 then slowly dropped it to 0 ( afr stays about 9.6 under boost)
vf stays around 2
how am i looking so far???

You really need to do some reading before you start in to this. It isn't a good idea to "Learn as you go" with this.
I have a HUGE thread on fullthrottletech.com that will take you through my experience all the way from running the maft in AFC mode to a full speed density tune.
There's another great reference by Doward (tho incomplete) on mkiiitech.com on how to get started with the maft. My thread sort of picks up where his left off.
That said, here are some suggestions:
Plug the O2 back in and leave all closed loop operations to the stock ECU (trust me on this)
Turn off all PTT options
Turn off AFR Tracking (will cause instability in your tune)
Initially tune using the Low/Mid/High user tunes (since you're letting the TCCS handle closed loop operation, you will only be using the 'High' user tune)
Set the 'Low' and 'Mid' to '0' (you won't need to adjust those)
Tuning suggestions:
As stated already, you want to start rich and work your way lean so set your 'High' user tune to '0' and set your mainscale to '0'.
Log a run. Unless there's something wrong, you'll be rich.
Take fuel away in the 'High' tune area slowly. From 3200 to redline.
Everyone's car is different and everyone tunes to their liking; but, I would suggest that your target AFR be 11.2.
I gotta run; but, I'll check back in later...

i read that last night
it was a lot of really good info thanksi also read everyting i could find on the maft pro in my car... your thread was the most useful
and thanks for the reply i will do as you have suggested
my only problem is i dont have an extra bung to put my stock o2 sensor in so i was wondering if i can take the narrowband signal from the alternate output on my lambda and tap it into the o2 wire on my stock ecu or do i actually need the stock o2???
if i do need the stock o2 sensor where is the best place to get a bung??
thanks again

I haven't looked at your log/tune yet but to answer your question, if your wideband can emulate a narrowband, then you can use that signal to feed the ecu. The analog output is different than an emulation, so you need to look up whether or not you can do that with your wideband. You can buy flanges that are used to mount the stock o2, which would not be difficult to get welded in.
thanks i am gonna change everything so no need to look at my log/tune i guess
my lc1 has got simulation
here is the description for my controller
8.1 Connecting the LC-1 to simulate a narrow band oxygen sensor.
- 18 -
It is possible to install the wide-band sensor in place of the OEM oxygen sensor. In this case the
meter's analog output signal will replace the OEM oxygen sensor's signal to the fuel injection
computer. EFI equipped cars typically incorporate a narrow band oxygen sensor. These sensors
are typically 1, 2, 3 or 4 wire sensors.
The analog output connector of the LC-1 can simulate the operation of a narrow band sensor
while the wide-band oxygen sensor is installed in place of the OEM narrow-band sensor. Factory
equipped Analog output 1 of the LC-1 is programmed to simulate a narrow band sensor. Some
vehicles are equipped with oxygen sensors that do not produce an output voltage but change
their resistance depending on exhaust gas content. These sensors cannot be simulated. They
are used in less than 1% of all vehicles. Refer to your vehicles specifications if you think that
your vehicle may be in this category. The same is true for vehicles already factory equipped with
a wide-band oxygen sensor. These cannot be simulated either.
Some EFI-computers will create a fault when the heater power wires of the oxygen sensor are
disconnected. In this case mount the old oxygen sensor in a safe place (but not necessarily in the
exhaust) and connect the heater wires to it to keep the EFI-computer happy.

so i can tap the wire at the ecu... but i dont really want a o2sensor ziptied randomly in my engine compartment... is there another option to get around the heat wire????

jdmfreak - You have a lot going on at once... I am unable to dig into this at the moment, but if you are successful at getting your analog input for the O2 connected and functioning, my question is if you are good enough to drive it north a ways and are safe cruising, I would be glad to help you get a good road tune complete... Up to you, just PM me... sounds like you may be to the point you are safe to cruise, just stay out of boost till you get it all worked out...
pm sent thanks

Thanks a bunch you guys
I still wanna know if there is a way I can trick the heaterSent from my DROIDX using Tapatalk
