In all honesty I cant imagine why anyone would try to tune without the AFR Tuner.
That's the main reason I brought this thread back. What would really be cool is a sticky that gave links to all the necesary programs....like tuner pro,afr tuner, ve master etc. I would bet that most people has not tried afr tuner. That's because it's kind of obscure. There is a sticky right now (I see) that would be a perfect spot for a link........
OK, so if I use this app I can tell the ECM that the ideal AFR for a certain RPM/Temp is, but it will have no effect on the actual fueling, and I'll need to modify the VE tables accordingly to add/remove fuel to match the new AFR. Is that a correct statement, or am I way off?
Originally posted by 11sORbust I was using this program at the track. The problem was that I couldn't change the actual fuel curve. No matter what it'll change the entire row. Another thing that woud be good is to highlight certain spots and fill them.
NOt trying to complain at all. :hail:
I'm surprised that you posted this ... actually, I am VERY surprised because you should know this. OF COURSE it will change the entire row. It is either going to change the RPM modifier or the coolant modifier. Those modifiers determine the PE AFR. Thus, if you change the RPM modifier then it will change the AFR at that RPM across ALL coolant temps. If you change the AFR based on the coolant modifier then it will change it across all RPMs. That's just how the $8D does PE AFR. It has nothing to do with the program.

Kinda like a pyramid, you have to build from a solid base.
This cannot be overstated. Amen brotha! Preach this forever because it is rediculously important.

Just wanted to say that the source code for this program was lost about 2 weeks ago. I backup all my home stuff but this source code was on my work computer and I lost the hard drive. I totally forgot that it existed only there. Oooooops. Gone forever in cyberland Thus, no additional changes or modifications to this program are possible.

Sorry to hear you lost the code. I am going to test out a DIY WB kit this weekend and figured that I would try out Mike's WB code. I fired up the car without the WB connected using a bin with the WB code. I got an instant SES light.
I have used the AFRtuner code to generate a new bin and have also hand entered the code to another bin. Both give an SES light. I ran two different tools to make sure the chesksums are correct and read back the PROM after burning and did file compares. All is correct.
So I disassembled the code. It looks like he moved the AFR location to the NVRAM area. I am guessing that not using the 0x3000 could possibly upset the ECM when the values are way out of range due to not having the WB connected. Or it could be causing a problem in the multiply code.
I am going to dig deeper tomorrow.
Has anyone else tried the WB code Without having a WB connected? I get a SES light on.
I have checked that the code is correct, the checksum is correct, and that the PROM (tried three different ones) read back correctly.
I will post what I find. Maybe it is some simple that I missed.
I should have read the Help file first. It says the SES should be on. Thank you Traxion for pointing that out. The website does not say anything about it. I might look into writing my own patch so that the SES isn't always on.

Does the hard drive still exist? If it does I might be able to get it back depending on what the hardware failure was.

Is there a possibility that you could give me an idiots guide how to actually use the AFR Tuner?
I guess what I'm missing is when you are on the Wideband and you see that a change is needed, do you open the .bin file you are running, make the change using the AFR Tuner, and use the Pocket Romulator or AutoProm to implement the changes Real Time?
Thus, no additional changes or modifications to this program are possible.
