You guys who are using older laptops for datalogging how frequent are your samples? Mine are just about 1 second apart. Is that enough datapoints for chip tuning? Is there a way to get more points with this computer or not? I have the logs as abbreviated and am running in DOS to try and speed things up. Perhaps this is as fast as this machine can think, and write to the HD... Thanks again.

there are two ALDL refresh rates.
The C3s (early 165s) all use the slower one.
So if your working with a TBI, or pre 89 TPI yes, they are slow

 

I'm having that same problem, getting data every .6 second on average. I know the computer will send it faster since my other scan tool will give it to me every .1 second. The laptop I'm borrowing is a 386/25 MHz (if that), so I'm looking to buy one for myself that's faster.

AFA tuning, it depends on what you're tuning. For closed loop (BLM's), you won't need anything faster since the BLM's don't change that fast. For WOT tuning, you can miss quite a bit of data in those 1-second spans.

 

The car is a 1988 Corvette and the laptop is a 25 mhz 486. The computer was free so I can't complain too much, but a faster one would be nice. Thanks guys...

 

Yeah, I should have just kept it simple. I should probably put together a stripped-down version of the code which will be more efficient, or at least streamline the core. With the new 850B code, you can go in and change a parameter or two to change the queue count for disk access. This might help a bit...

The program has gotten fat, and it's kind of time to trim it back. I think we need a 'basic' version (no pun intended) which will be for ultra-low overhead. Nothing but the essentials. Hmmm...
