Sorry if this has been asked and answered, I did a search and didn't find anything.

Does flashscan use the high speed bus to program the PCM? I'm wondering if I'm still going to be stuck in slow-mo like I am now with Edit.

Thx.

FlashScan uses the high speed bus.

Reflashing most PCMs takes just under 30 seconds
Reading 512K of most PCMs takes around 1:50 seconds
Reading 1Mb of Most PCMs takes around 3:40 seconds

The above times are "best" case. If the bus is noisy and retries need to be perfomed then the data transfer time may extend by 10-20%.

how much will the speed of the computer matter?
I bought a P-2 300mhz with 128 ram will be upgrading to 256. with windows XP. will just be using it to tune the car

For just reflashing and reading the PCM the PC speed will not matter.
I have tested both reading/reflashing on a Pentium 233MHz and it is the same speed as on a 1.5GHz P4. The bottleneck is the comms speed between the PCM and the PC. Even on a 233MHz machine, the CPU is only 4-10% busy while flashing and/or reading.

However, to get the most out of the editor and scan tool you will want something faster. We are recommending 800Mhz or more. 1GHz+ is ideal.
