Could we start a post with the HKS AFR settings?

I have a full 3" (no cat) and the car is running pig rich. I'd like to get some initial numbers before heading on the dyno.

What #'s are being used..

 

what exhaust? try asking Ultimate Racing... they were using an HKS AFR...nobody else is/was that I know of...

I have a JIC w/ Perrin cat delete and RMR DP..

I called Ultimate and they didnt want to give up the #'s.

Nothing Nobody has an AFR?

 

i will have afr numbers soon, i'm going to take mine to altered atmosphere and they're gonna dyno tune it for me i'll give you the numbers as soon as i get them (within 1 week hopefully)

 

Right on

I'll post mine as well. I've been told that you can lean out as much as 12% above 5K. I won't go that high until I have a wideband on the dyno.

 

Cars are like fingerprints in that each has to be mapped individually. Things like weather, humidity, altitude, quality of gas, etc all have a significant impact on what fuel settings should be (as do figures such as base timing, etc.) Best bet is to get a datalogger, start with a baseline log of your car (in stock form ideally), and log as mods are made. The idea with the piggybacks is essentially to make the car think it is running stock equipment....this will give you the most consistent gains possible day to day.

 

that is true, all differant... , but nothing beats a dyno tune, but it will at least get you an idea...

ASPURSELL, when are you going to AAM? Maybe I'll come up and see how you do!

hopefully next week it all depends on UPS

 

You guys are in MD? Cool... Do these guys have an AWD dyno? I am in Bowie...

 

yes and they have an awd dyno

 

After the dyno, post the numbers. I'd like to see how different yours, mine and Ultimates are (if we could get a hold of those).


BTW - putting a wide band in the mid-pipe is too far back? I dont have a cat, so I was going to use the rear bung. Good idea?

 

Thanks. I will go check them out and setup a dyno session to tune my S-AFC with the RMR setup I am just bought.

 

Anything to make a buck.

As soon as I get some AFR numbers i'll post them immediately. Even if it isnt dyno tuned it gives a good baseline.

on the 28th at 9 am i'm going to Altered to get my afr dyno tuned then i'll post the numbers up

 

I might be right behind you that day if I can't get in during the week. My last dyno session I had 3 leaks in my exhaust and wasn't getting an accurate a/f reading.
