Default Afraid of a blown engine

oK, this is the deal. I got all the turbo setup installed with DSM TD05H 8psi, 450cc, 1G dsm blow off, D16Z6 stock engine. I dont have money to buy any narrow or wideband to tune my car, and im going to tune it with the SAFC.

I read a lot about tuning with AFC, pros and cons.

Does exist any problem if i tune the AFC on the rich way, i think is better than being lean and a blown engine.

Maybe this settings

its not even stock timing, its super advanced timing

I ran the afc with 8psi for 5 months, better run that ---- rich and retard the dizzy. Dont retard the dizzy too much though because thatll raise your egts and if you have a ---- manifold itll become swiss cheeze.

very true, run stock ecu on 450s to be safe, lalalalalalalalalalalala, HOW many times is this gonna be talked about? THIS WEEK.

you better hope joseph davis doesnt see this thread, he will probably bite your head off.

ive seen some cars with high power runing w/ SAFC and no problems.. no hondas but.. ... i guess runing with safc.. have a limit about a setup.. but runing with a ecu chipped you havent not limit.. about to tune it.. and of course ecu is the best.. i think..

I found this articles, what do you think about. I can tune it with this?

Heres the first one
-----------------------------------
One of the unused wires is blue, and the idea here, is to hook it up to the 02 Sensor. If you do that, and you go to the etc. menu and select the Sensor Check option, under #2 you will see your 02 Sensor voltage.

Basically, the voltage read from the Stock 02 sensor can be translated into three categories: Lean (too little fuel), Correct (Just Nice), and Rich (excess fuel). Unfortunately, the differences between the three categories are sometimes slightly blurred and it is hard to tell. For that reason you should always tune a little on the rich side.

For reading the 02 Sensor voltage (remember all readings are taken at Full Throttle). From OV - 0.88V (lean), 0.92V (just nice on pump gas) and 0.96V - Up (rich). Note: When you are at partial throttle (or when the car is idling), the 02 sensor voltages will cycle from and display anything from 0.2V and 1.0V. So donít panic, itís normal!
----------------------------------



Heres the second
---------------------------------
hook up the blue wire to the o2 sensor signal wire. you can do it anywhere on the line itself or at the ecu (pin C15 or 16 i believe). its a signle white wire at the o2 side and the ecu side. you can find it easily (ecu side) buy cutting back part of the harness loom. look for a really thick brown insulator. in that insulator is the white wire to and from the o2 sensor. *be sure to use a larger guage (thinner) wire when hooking it up* (super low amounts of current pass thur this wire, too thick of a wire the ecu ***** up and throws codes for the o2 sensor) once the blue wire to the afc is hooked up start the car. goto the main menu, arrow down to "etc". once in the "etc" menu goto sensor check. voltage off the o2 sensor will be listed under "input 2" or "in 2". it mesaures up to one thousanth of a volt. when you first start the car you will only get a reading in the hundreths of a volt. this is because the o2 sensor is only usefull once heated.

how to tune.
o2 voltages rage from 0 to 1. 0 being lean as hell and 1 being rich as hell
.500 - .600 volts corresponds to a stoichiometric (14.7:1) air fuel ratio. this is a dead nutz air fuel ratio. not rich not lean. anything higher than that correcponds to a more rich mixture. anything less than .500 volts translates to a lean mixture. anything over .600 trans lates to a more rich mixture. optimum performance during WOT is a slightly rich mixture.
