It would be really nice if Clint would post the 1.8g source since it really doesn't look like he's going to derive any income from it. That would be in the same spirit as when Dmitry made the source available to Clint originally.I'd like to take a look at the source also.
Clint, it looks like there's only 1.5d source available, could you update it in sourceforge or post here.

Has anyone heard from Clint. His last post on the board was 10/16. Anyone know where he's at and that he's ok?

Dunno if anyone else is having this problem but I found a bug....
Using an aem wideband hooked to the egrt and selecting wideband o2 on the mmcd 1.8g. The afr values are not correct, if you use 0-5 volts everything seems to be just fine.
Edit... actually the 0-5 volts seems to read about .25 volts lean but that may be from voltage drop running through the ecu and into the logger. While the wideband function reads over 1 volt richer than actually. It may be reading lambda afr's?

I've got my MMCD up and logging but before I ask any stupid questions let me start with this one. Is there a definitive list of all the items that can be logged and what are acceptable values for each ? I've been searching. A manual would be a great improvement for this. I had trouble at first getting it to log because I didn't click on the value names, so nothing was logging. I figured that out with some help, but reading the data I get back is a little more daunting of a challenge.
Can someone please point out a list if it exists ? Thank You.

AEM's output is 0v = 10.0 afr, 5v = 20.0 afr.
According to the first post, MMCD starting with version 1.6n uses wideband calibration 0v = 8.0 afr, 5v = 22.0 afr.

you can also change the... battery voltage input? i can't recall off the top of my head and my palm is out of juice, pretty sure it's battery voltage input to allow the wideband signal
I haven't seen one but I'd be willing to help you out. I'd also like to help out the MMCd project but I have no programming skills. I could test and write up docs if anyone wants to move the project forward.

Sir the information you need is in the very first post of this 106 page thread. I sugguest you review that post again including the hyperlinks.

Re: MMCd Logger New Features and Sensors Archive Latest Information
serial comm error
or
ECU comm error
Why? What is the problem, I cannot use my data logger at all. It syncs with my PC and it works fine with all software I load onto it but this MMCD V 1.5 once gave a couple weird numbers and that was it. I tried everything but no log. It just wont work. Nobody else has an answer maybe you do. I wish I had another Palm just to see if it is the Palm or the palm cable. But I dont and cant get a local 3SI dick to even reply to me and try to use his Palm to see but if you have an extra I can try it with maybe?? Or Ill try to buy another on ebay and waste my money. I'm just pissed tonight and Im tired of sitting in my car idling all my gas away trying to get my data logger to work. And for what reason I don't know. I have had sellers of cables borrow me cables and sent them back but nothing. Anything?? Ive tried all released versions and I take it off pause it cycles through in the bottom left corner what I have checked then pause comes back on. not one display no numbers nothing. making me crazy
Well you seem to maybe know alot about this datalogging stuff and my question is I just bought a new Palm M100 and have 3 cables now and not one will synch with my car. My ECU is perfect. All I get is in test mode for example is

I have not heard from Clint in some time, but I'll give this a whirl.
What sync cable do you have?
What logger cable do you have?
Has anyone ever been able to log that car?
Are all the required pins present in the logging connector under the dash?
What is the baud rate set to?
What version of palm OS is in that palm?
Bob

cables that came in unopened packages with the Palm and the same cables Jim Delucca makes for other companies. He has sent me 2 trying to help me. Its not that cable and also I bought another cable from a different maker on Ebay. I can get a reading with a needle style volt meter and it says code 14, TPS. Ive talked to everyone but you. The 3SX service manager Chris also is baffled as it should read if I am picking up a signal to a volt meter. I have gone through all the steps over and over but nothing. If I was to buy a colored Palm which do you recommend for a low price of course. I want to try another palm and see. Guess I have to buy it as I cant borrow one locally from anybody. people I work with have them but they inconveniently cant find them and Im in Utah with no help. I guess Ill buy a colored one and see. Which do you recommend. Got an extra confirmed working you want to loan me. I can pay a deposit and for freight. Im confused and tired at this point. Just burned out on it now. Im Giving up while everyone else enjoys theirs. It sucks bad

Can I use a laptop and a USB cable? How is that done and bypass the palm all together. I have a $2600.00 ASUS laptop but it don't have a DB9 connector its modern so i would need a converter from 9 pin to USB I guess , does tha even exist? How do I use a laptop to log? that may be a way to see if its the Palm or not without spending more money for no reason. ideas? Thoughts? Help?
