Since when did SAFC2 do timing?

Not sure about the 1st generation MAFT's ability to "fine tune", but I do know that they only adjust in 5% increments and IMHO 5% leaves a lot of room for error. You're not going to get a good tune without the fine tuning device installed.
Open dump precats could affect NB and WB accuracy because it's just easier for the sensors to see fresh air.
Put an exhaust system on there and get your tuning devices up to par and then go tinker with it. Otherwise, I feel you're wasting your time.

I will check his fuses later tonight when I go out there to help him again. Hopefully he gets on here soon and sees this thread.
This is such an easy thing to do, and neither him nor I is mechanically challenged. so I dont see why we are having so many problems with this
i didnt realize this was still being posted in so much.
my mods were listed correctly, except i have a dual solenoid boost controller.
i was told my someone it did have timing control on it... oh well, i guess thats life.
and as spddemonvr4 said, this is a simple thing, not much to it. now i will admit i only have one 02 installed, and that may be causing issues. which 02 is more important, front or rear? or do they both have to be installed for everything to run properly? and before you ask why i dont have both its a simple answer, they didnt come with the car, im out of money, and more importantly i was trying to keep my wideband hooked up somewhere so i could see whats going on. i put it on the rear bank because it runs leaner than the front. so if i get good readings on that, it should theoretically be alright on the front as well (assuming a lot, i know).
so, for those that dont like reading:
do i need both 02's? i know ideally yes, but if i only have one, front or rear?
if you say i need both, i guess i am pretty much required to buy a downpipe huh?
my maft is hooked up correctly and set for the correct injectors. i assure that.
thanks for the help fellas, keep the info coming, im still learning a lot.
You should definitely get a downpipe to install both NB's and properly place the WB before you burn out the sensor.
I would [and do] listen to [my many] dataloggers before a wideband.

The downpipe should be a no brainer, it was explained earlier why. The secondary O2's are the ones that are optional because they only deal with cat efficiency.
The WB sensor can only tolerate so much heat. Placing it right next to the turbo might be bad for it. My manifold can get up to 1600*F when deep in boost and that's with spraying W/M. It gets near 1400 just cruising. I believe the Bosch sensor that Innovate uses isn't supposed to go over 900*F. The sensor should be in the DP for multiple reasons. There is a lot less heat at that point in the exhaust as that's one of a full exhaust system's jobs(heat dissipation). The other is that since you are only using one WB you get both banks exhaust stream.

yeah. i didnt think about the wideband being burned up, but like i said earlier i figured if i put it on the bank that ran leanest then i would be safe as long as it read well.
ill get a downpipe and o2 sensor and see what happens. dang money, cant you just grow in my pocket for once?
