Default Autotap Data Collection Rate?

Is there a way to increase the sampling rate on AutoTap? I am trying to collect data and I get about three data points between idle and redline. That's a lot of missed info? I have a good laptop so it's not that. Any info would be appreciated.

Thanks

You might wanna try emailing Autotap to find out for sure, but I think the sampling rate increases as you decrease the amount of items you are logging.

Yes, the only way is to run less parameters. Focus on only one or two things at a time for best sampling rate.

Another thing you can do decrease the update time.

Hit enter on an item, and you will get a menu that says slow, medium, or fast.. by selecting slow it won't update as fast so you'll get more info from the other data that your looking to monitor.

When monitoring WOT LTFT's, I'll put them on slow because they won't change at WOT.. so there would be no need to update the value at a faster rate.

Actually no, that won't help. That effects the viewing of the parameters only. NOT the recording of them. <img src="gr_sad.gif" border="0">

Hmmm.. I'm refering to Dos Autotap.

I know the logging feature of autotap ain't the greatest. I have also not done testing to prove me or you right or wrong.. I'm just thinking..

I have done many many logs.. in the 100's.. I log quite often.

If I add 10 items.. 1 being RPM.. they all are set to fast.. I could see the RPM increment being rather large.. maybe 500 rpm's.

Lets say I set them all to slow except RPM which is still at fast.. I could see the rpm increment in the log coming down to maybe 300.

What do you think?

I'm referring to the DOS version too.

Page 15 of my Autotap manual says...

"Removing unwanted parameters will speed up the acquisition of desired parameters. Also note that the update rate setting has no effect on the logging function. All parameters are updated at the same rate."

Awesome. I did not know that.

Thank you. <img src="gr_stretch.gif" border="0">

I know this doesn't help you out with Atap, but we had so many guys complaining about the speed of Atap that we wrote our own scanner. Currently it will do minimum of 10 frames per second while returning 24 different data items.

Guages, graphs and digital data - all synchronised and all updating 10 times per second.

When we start logging/overriding spark and fuel maps - timing is critical, so we bump the refresh rate to 20 frames per second with 6 data items.

I have hears that this software:
http://www.obd-2.com/

Logs and updates faster than autotap but is a little more technical. Its also cheaper.

Logging speed is very critical. The more data results, the more there is to analyze and the better picture you you will have of how the car is performing.

Franches -- Running in DOS which will run faster than the windows version,Autotap will update 1 parameter 30 X per second,10 parameters roughly 3X per second,& so on.This is according to Atap engineers & I've verified that myself.So as Colonel said keep the # of parameters down to a minimum especially at WOT,since things are happening real fast at WOT
