If I understand right, when in a lean burn condition the O2 sensor output is basically offscale low all the time? If that's the case then I have a lot of ...

I searched the archives for lean burn and read several different thread outlines that popped up. It left me more confused than before. Although my car...
Todd, Thanks for the reply. I wasn't asking for any of your source code, although of course we're interested if you post it. What I'm talking about is your...
What I'm trying to do is add to this code so that the NLTS stutter RPM doesn't happen until approximately 30mph. The reason for this is to aide in launching....
Ok, my bad. The typing got me to think of some things they way I needed to. What I want to do is not allow the NLTS to occur until the value in C6 is below 11....
TalonRacing; Yes,those are two separate issues. The fuel maps only apply when in open loop. When in closed loop the ecu is going to search for stoich by...
I seem to be getting more and more confused if that is the case then. Now you've got me second guessing myself. I believe during closed loop, the fuel maps DO...
For the archives this is how you can do it: 4F50 96 C6 LCAA L00C6 ; load speed sensor into accum. A 4F52 81 75 CMPA $0075 ; test if car is moving 4F54 23...
Thanks for the info. I was wondering myself how to do this. How do you know that 10h is 30mph? How do you figure out the values for different MPH? ... From:...
Log address C6 in MMCD. With the car stopped the value is close to 255 decimal. This value drops as you speed up and notice how unlinear it is. Put your speedo...
Thanks for the info. I have pocketlogger though. Maybe I could change the airvolume parameter to the VSS address to log it? I've read that the 1g VSS is...
The 1g VSS is not useless, its just a little different and you have to understand its function. I got everything to work well. Why not download MMCD, do a...
The stock VSS is useless for things like the AEM. http://forum.aempower.com/forum/index.php?topic=3274.0 It gets the job done for the 1g ecu though. The only...
I read that thread and it made me think of something. The 1g ecu allready has the code to handle the speed sensor and make it work well. The stock ecu also has...
Ive been looking through Christians commented source (how helpful is it!) anyways, the function to lookup values from the maps (lookup2 d) only passes 4...
... The VSS does not change with vehicle age - it either works, or it doesn't. The calibration value for the VSS pulse is directly related to the wheel ...
OK here's how I understand it. The stock O2 sensor doesn't have the sensitivity to nail down any AF ratio except 14.7. It's built into the sensor as a rapid...
... Actually, what is stamped there might be 1025/mile, meaning 1025 rotations/mile. Since there are four poles to the magnet arrangement, it becomes 4100...
Yes, I see that now. I was just going by what I had read in the archives. I actually went back to read that post just now and I misread the archives. I am...
I'm confused. Is MS going to supply Windows CE chips with Windows Genuine Advantage in their ECUs? Are there going to be pitstops to phone home to MS to verify...
and an update for a possible security hole due to a hacker in 'Jersey. ... From: dsmdan18 To: dsm-ecu@yahoogroups.com Sent: Friday, July 07, 2006 3:57 PM ...
I've been fiddling with Jeff's lean burn code the last couple of days and I noticed something odd. Using the TMO logger DRB2 tool, the ECU ID will toggle back...
