what are the min requiremts for a computer that would have to run this software? and datalog as well.

 

Specs are all over the place - a lot of it depends on how much crap you have on the laptop.

Really, bang for buck would be dropping $150 for Crome Pro. I've seen 450 Mhz P3 laptops with PCMCIA USB 2.0 cards pull 25 samples/second with v1.1.11h. Not too shabby!

FYI, the two ways I'd go if buying a laptop would run you in the $500 range:

- Thinkpad T30, last of the IBM built thinkpads before China/Lenovo bought the name, and last of the true T-series which are indestructible. You can find videos on the internet of T-series Thinkpads left in the woods for the winter, or run over by pickup trucks, that still work. 2.0 Ghz P4, it's pretty quick, and you can get them sometimes with a month or four worth of warranty left on them. Good ****, the *only* way to go if you are buying used for less than pennies.

- Dell Inspiron 1200 or wtfever they superceded it with (D120 I think it's called?). $450 + shipping speshul, new out of the box, and I know a guy with a 1200 for the last 10 months... seems to take mild abuse well although it's no Thinkpad T-series.

 

well honda says 400mhz. i just checked it out. will a faster computer be able to datalog more information? i mean will it plot more points on the graph or is it just a standard (per second) rate?

You will get a quicker sample rate with a faster computer. With Crome Pro, my 475mHz 512MB laptop was getting about one sample per second. I upgraded to a much quicker computer and it now does several per second without a studder.

Personally, I would never try and do cell tracing with a slow computer because it just can't give you enough samples to prove worthwhile.

Uberdata ran fine on the slower laptop, though.

 

A lot of the slower computer's sample rate issues is due to:

- Bogged down with wrong OS and/or a lot of TSRs (terminate and stay residents aka a full taskbar) and/or spyware because you foul up your tuning gear with web surfing.

- Old serial or USB 1.0/1.1 connection. Upgrading to USB 2.0 = OMG

Taking a datalog at 20-30 samples/second is trivial for an 8 bit microcontroller... the dinky MCU in the Honduh ECU is doing a whole lot more and spitting it out the serial port. Any problem with a (dated yet still more robust by several orders of magnitude!) laptop that keeps it from being able to log a significant rate is entirely due to user error!

Good information. I guess I shouldn't have paid $600 for a new laptop when my old one would have worked.

 

so how does a pentium 500mhz sound datalogging with uberdata w/ a serial port? i should try and hook up a usb 2 because that will be faster oppposed to the serial port?
