goals:
-break into 11's [aiming for 117-122 trap]
-do it on a cheap budget, self built&tuned
-do it in street trim. as in drive it right off the street and race without changing anything.

lots of researching went into it. ill be doing everything myself, including tuning. ill be using a mustang dyno(and virtual dyno) for before and after results and backing it up at the track.


list of mods:

day 1:
got evoscan 2.8 up and running with OBDI. turns out you need a null modem cable to make it work. did a couple logs, nothing to report, everything looks good. have mmcd+palm as backup in the car.

day 2:
installed lc1 wideband[pic]. placed it in the stock o2 spot and using its narrowband signal as well. logging on evoscan via com4.
sent out injectors to get cleaned.

day 3:
testing of egrt input on ecu to use gm 3bar map[pic1] [pic2] [pic3] [pic4] [pic5] [pic6]. pin is there, circuitry is there, just wires are missing. tested limits, works. installed map and tested with evoscan, works. redid calculation in program to get accurate result. logging on evoscan now.
installed safc same time[pic1] [pic2]. zerod everything out. went for a drive to test, good to go.

yesterday:
replaced plugs with bkr6e, gapped at 35. replaced wires with oem. i really need a ypipe with coupler, i hate putting the stocker back on.
got injectors back, all flowed @90%.
installed them. have 2 spare.
current safc settings: L30%[-20@1,2,3,4,4.5,6,7]/H50%[same as low]
started car and its all good, o2's cycling, ~14/15 on the wideband sustained. havent had a chance to go for a drive yet.

today:
tuned safc settings: L25%[-20 to 3k, -18 to 7k]/H40%[same as low]. ecu goes open loop right at 40%tps.
tested wot to 4k so far, starts around 12afr from 2500 and ends at 10.6afr so far. 0 knock with 10psi. started raining had to stop. waiting for sunny day to finish. once i get 14psi tuned ill throw in the supra pump and start again.
im tuning 500rpm at a time, so starting from 2k i go to 2.5k. then 2k to 3k, and so on. still waiting on my turbos to be made
