I see that this has come up in the past without a solution, so I'll modify my question to this: Is it possible for a programmer to modify or copy the code from a FF OS to enable it in the GTO OS?

I live in Colorado where there is abundant E85 and if I want to use it I have to use the 2006 or 2007 van OS so that my fuel composition sensor is enabled. Colorado also has a stringent emissions...
Not exactly although it seems that effective area is a factor. I experimented with it back then and in the end returned to the stock settings in that table because it ran better with them. Since then...
I just read a post on the idle tips and tricks thread where 5.7ute speculates that rafig is something to do with the way the pcm uses IAC effective area to calculate airflow. This makes sense to me.
Yes, '82 corvette with stroked LS1/6 and enough cam to affect the idle.
Bearing in mind that it idles pretty well as it is, here are my RAFIG results and my current desired air:
22441
22442
And here is the actual measured airflow in gear:
22443
I can't understand...
I experimented with the 06 and 07 OS and the 2004 GTO OS, I discovered that the car runs best with the 2004 GTO OS. The 07 runs pretty well and starts well but doesn't do Catalyst monitor for...
Hi Joecar, and thanks for responding! Yes, it has cats and when I use the 2004 GTO OS the catalyst monitor shows as supported and it completes the monitor when I do the drive cycle. It's only the 07...
I'm running this OS in my LS6 powered '82 Corvette and the scanner says that Catalyst monitor isn't supported. This caused me some trouble when I went in for my emissions here in Colorado, I know...
Has anyone got a file from an 06 or 07 Express Van that has flex fuel turned on? My 07 file doesn't have it turned on, or the related tables populated. I copied the tables from another file and...
Hi Joe, thanks for your reply! It's kind of a mixture, 383 LS6 short block and intake with ported 243 heads and a 1MB PCM from a 2007 Express van with the 12613248 OS and 12606602 Calibration. I've...
Nothing? It seems like a valid question, if you have other spark tables like the IAT table and to a lesser degree the ECT table (which really only affects at lower engine temps) changing the amount...
I see that the IAT table retards timing based on intake air temperatures, which explains why sometimes when I'm logging spark knock I don't get any and others I do. Should I just keep removing spark...
Thanks for that, it worked just as you said!
That did the trick, thanks for your help!
I'll give it a try then, thanks for your reply!
I noticed there was a 3 gms/sec discrepancy between these 2 and am wondering what I can do to get them closer. I'm using the 12613248 OS with a 1 MB PCM to control a stroked 2002 Z06 engine with...
Thanks Joecar, so B4307 is critical to cold starts? I've got those values a little lower because I was getting a "cruise control" effect using the logged values from MAF vs. ECT.
I keep that one open in a tab on my browser and it's been very helpful in smoothing my idle. I've got my VE, MAF, and spark tables pretty close as well as my desired air and IAC. I guess I was just...
My 383 LS1 with ported heads doesn't start instantly like my stock LS1 did and I'm wondering which setting to address this. I don't think it's too far off as it starts fairly quickly but I'd like to...
Well shoot, I don't know what the equivalence ratio means! I will recalibrate the wide band and hope that it works. Is it possible for the null modem to be installed backwards? It'll go on either way...
Looking a my calc.selbens I have some non linear readings with spikes, I'm wondering if my MAF because of it's non traditional installation could have anything to do with that. It's inside of this...
I just did a datalog and some of the cells have really big numbers in them, what am I doing wrong?

Here's a screencap after changing the units, thanks for that I couldn't go on without it.

I need to set the B0101 table display units from kPa to % and can't seem to find the setting. My log is displayed in g*K/kPa and my B0101 table is displayed in kPa, can anyone point me to the setting...
