Anyone got a ball park settings????

 

its prolly good especially if you increased fuel pressure with your FPR ... which you didn;t really need.

Greg

 

so your saying these settings are correct or seems right??

 

Anyone???

 

was it dyno tuned?

 

haha yeh its tune but the truth seems like its gay!!!!! So i'm tryin to mess around with my settings now. What you guyz think? Post up your settings please and lets compare

 

What's wrong with those settings? Did you get a graph of the A/F mixture? Our cars run rich at WOT by default, so I'd think that'd be just the way to go with mild mods. Higher A/F will yeild more power. I'm not sure I see what the problem is.

 

just look at your dyno plots, did it get better or not?

 

guys here the dyno it wasn't by a graph so I have to type out the numbers so bear with me There was 2 runs. I don't know which one was my final run and where I made the most power at and I don't even know where is the vtec dip. Can Someone help me out here with my dyno. How much am I making at the wheels with these bolts on? I'm clueless. I'm thinkin maybe the final run was with the a/f ratio tune out at 12.0-12.6?? Can you guyz tell if this tuner is knowin what he doin and if he tune it correctly to extract the most power outta my car?? Also if I should just use his dyno settings as I posted up there earlier??? Thanks for all the help I appreciate it.

Before and after. The top one is after...I hope. See how the A/F ratio goes up at each point? More air means hotter burn and more power. Peak power is 137@7750. Leaning out the mixture resuled in an average gain of 3-5HP and widened your powerband. It appears that your tuner knows exactly what he or she(in my dreams) is doing. What altitude are you at BTW?

 

BTW you can use Excell or some other spreadsheet to turn that into a graph fairly easily. Makes it a bit easier to read.

 

haha man it took me a while to keep trying to edit it to make it better and easier for you guys to read it hehe. Besides If I do it with Excel. I don't have anyway of hosting it cuz I have no digicam or scanner. So I had to do it manually took me a while to get it like that how it is now hehe. Hmm really the tuners know what he is doing??? In my other thread they bad mouth him like crazy saying he doesn't know wtf he doing and he sucks at tuning!!! Its in the Integra Forum.

 

I'll certainly look it over, but if that's all the information, then I don't understand what he allegedly did incorrectly. Looks like he set A/F ratios to the best values available. Often people are quick to knock others work without even looking closely. There is a way to get spreadsheet graphs into picture form, I've done it many times. If you want to do it lemme know. I'll just have to figure out how I did it.

 

Well yes they are low numbers, but I think you knew that already. Without all the variables though, it's not worth getting upset about. The temps are listed, so the atmosphere(altitude) is left, that's why I asked. Strictly looking at the A/F ratios compared to your power curve I'd say the settings are close to optimal. A 5k Vtec point is rather high, but not all that high. I run mine at 5900 with the Crower cams, any lower and it bogs a bit. It's very easy to experiment with this though, simply change it and stomp the accelerator. The secondaries don't open till 5250 if memory serves so you could well bog down there. There's a setting to adjust this on the Apexi unit, it's called unmatched fuel...if memory serves. Just write all your Vafc settings down, and monkey around with your Xover points. If you find something you like kewl, otherwise just revert to your current settings. How many miles on the car? What equipment do you have on there exactly?

 

Hmmmm I don't know the altitude at that time so I can't really tell you. U have after market cams thats why. I still got my factory Gsr cams. Wouldn't you think the vtec x over is too high on stock cams???? So if I was to mess around with the vtec point how should I set the fuel??? lean -2 all the way??? Oh yeh, when I dyno and install the vafc it had only around 5000 miles or lesser ummm it was on 17" tenzo av7 rims with Federal tires 205/40/17 if that helps. Thanks for your help man I appreciate it. I thought the car make most power with a/f tune around 12.5? Why was the 14.0ish was the after graph??

 

The altitude at the time? Tell you what, if it changes substantially, move away QUICKLY! I raised my vtec point on the stock cams too, though less. I suggest you leave the fuel alone and just do one thing at a time. You can't be very scientific about this w/o testing gear. Don't remove any controls from your experiment. Hotter burns occur with MORE air, not less. Thus a 14:1 ratio yeilds more HP than 12.5:1. You want the A/F ratio as high as possible w/o risking detonation. Detonation = teh bad. IMO your tuner set them very skillfully, but I wasn't there. 5k miles on the car? If so that's very low, your car could well gain several more ponies as it ages...like fine wine.

 

hmmm probably around 75°F. It was somewhat chilly at that time. Thats an educated guess cuz you wanted to know hehe. Hmm, what do you mean when you say don't remove any controls from my experiment as in my vafc fuel settings??? Hmmmm crap i'm getting mix information here. Some people on honda-tech in my other post they say the best to extract the most hp is from 12.5-13.8ish or so a/f ratio. Hmmm and here you telling me that its best if its high. Yeh, sure its safer but what if the fuel don't burn if too much fuel letting in?? Hmm confused...Can you or someone else clear things up for me thanks.

 

Well ummm...it seems to me that you have the proof right in front of you. If 12.5-13.8 is perfect, then how come the car made more power at some revs with 14+? Nope, I say leave your fuel maps alone and mess with your x-over point if you like. It's your car though, I'm just offering my opinion.

 

Yeh, I know I'm just trying to get some opinions and all comments are appreciated and welcome Yeh i'm goin to mess with the vtec crossover and find that dip first hehe. Pretty strange i'm still somewhat confuse about the a/f ratio though. Wonder why it made more power with 14.0ish ratio. as to others telling me that car make most power around 12.5-13.8ish.

 

mine made the most at 14.0 too on the dyno.. but ran faster on the street with ~13.1 - 13.5 on the dyno..

i think the car runs about .5 leaner on the street?

Theoretically they should be using large fans to simulate air intake on the dyno to negate that difference.
