It for a Honda Prelude non v-tec h23 with all the basic bolt ons i did the blue wire mod to see what voltage the O2 is sending at WOT and its around .92 which is pretty fat so could anybody give me some help on setting lo map then hi thanks alot

 

up up down down left right left right ba ba select start.

You need a REAL wideband by the way...

 

To tune it you need a dyno

 

i know that but i jsut wanna basically tune it as best i can with wut i got and ive read where the voltage for NA should be around .85 for WOT so i jsut wanted to pull a lil bit of fuel so i mean i kno its not gonna be tuned as good as a wideband and dyno but its gotta be better than it is i dont wanna get drastic with the changes or anything i jsut want to fine tune it just a tad as best i can

Konami code! Works for everything, even Preludes.

 

is anybody gonna help me lol got all these army code words goin

 

hahah, contra.... good times.. good times.. seriously though take it to a reputable dyno shop and have it tuned. its worth the money trust me

 

street tuning will only lead to headaches, especially if you don't know what your doing. Having a dyno tune it with a wide band gives you the best out of your car, whereas if your street tuning, you have no idea what's going on, your only guessing.

 

^^^i agree with those guys

btw......i thought the code was from the first Sonic on SEGA. it would get you to all the levels.....no wait, that was: up, down, up, down, left, right, left, right, B, A, start. oops. It's amazing what you remember from your days as a dude who never left his room playing video games 10 hours a day.

 

well i dont really see the point in payin that wen ill only gain like 5 hp i jsut wanna trim it up a lil bit nothin drastic ima pay for the dyno time wen i get my turbo stuff

 

The real gain from the AFC is when it's used with aftermarket cams and head work, if you intend on going turbo this is not the thing you'll be using. I just took out my VAFC the other day because it's not as indepth as what an actual EMS is and what I need.

How will street tuning lead to headaches? Street tuning (in my opinion on SIMPLE set-ups like this) is way more benificial than a dyno tune. The only thing dyno tuning will allow you to do is dial in your ignition timing which the AFC cannot alter as well as make sure your AF is dead ***** on. Now... I have the plx m-500 with datalogging so either way doing street tuning or dyno tuning I can monitor my a/f to a tee. Dyno tuning also does not properly encorperate the 'real-life' conditions the engine will see due to heat-soak, different air temperatures, and constant engine loads (assuming you are on a dyno jet). For a daily driven car, street tuning is more important than dyno tuning. End of story.

 

yeah but we know he doesnt have a wideband o2 sensor so it wont help him unless his car alrady has a stumble or sumthing.

Good stuff

From my memory, street tuning is just tuning on the street, as opposed to a dyno. Provided the same equipment is used to datalog and tune, you can get excellent results from both. I tuned my Prelude w/ a VAFC and a Zeitronix wideband logging through my laptop, and it was a breeze.

DO NOT TUNE WITH THE STOCK O2 SENSOR! It will only tell you if you are rich or lean. When tuning, you want to tune at a certain a/f ratio, so you will need a wideband to log and tell you where it currently is.

 

i was also planning to buy a safc and a innovative motorsports wideband in the future hoping that i can street tune my own setup, only a h23 with bolt-ons and maybe a cam upgrade . so with this given setup, if i tuned it to the right a/f ratio from the wideband at certain conditions, will this setup be good enough to for me to tune my car with ? it seems like it from some of the posts, but i wanted to make sure and get a definite answer .

and i know its off topic, but does a cam mess with any of the air or fuel settings in a car when installed ?
