COM port 1
ok i am trying to connect my laptop to my MAP ECU which controls the fuel injectors for my supra 7MGTE in my truck.
http://www.mapecu.co.nz/index.html
The problem is that the program on my laptop isnt smart enough to find the USB to serial adapter i bought. I do not have a serial port on the laptop so i bought the adapter to try and get around that problem. The program only allows you to designate which "com port" is trying to communicate with the MAP ECU. What i need to know is how to find out which "com ports" are doing what, and if any of the USB ports on the laptop have been assigned a com port number which i could choose from the program.

the "ports" expansion does not exist on my laptop, it does however exist on my desktop but that doesn't help me with something that is in the garage. The list goes from PCMCIA adapters to Processors on the laptop. On the desktop it lists COM1 as a "communications port" and LPT1 as the printer port but neither of those are the 9 pin serial connector i need.

Your desktop should have a serial connector. Almost all desktops do.
What OS are you running on the laptop? Try the very bottom of the list at USB controllers. You should still have a Ports listing.

Midiwall just reminded me of a handy tool to monitor serial ports... Portmon from SysInternals. Their site is slow now because it's being Slashdotted. Give it a shot and see if that utility helps figure out what your ports are doing.

here, if you goto my computer > control panel > system > hardware > device manager > and goto an expand the list labeled "Ports ( COM & LPT)" your adapter should be listed there with the COM port the computer is using to communicate with it I had the same type of connecter to tune my smt and to use my scan tool, so hit me up if you have any other questions

Jeremy-
Change it to COM4 in your MAP Ecu settings, and that should get you rockin'.
That's what I'm using for my MAP Ecu in the Poopra, but that's with a Belking serial to USB adapter.
You're hopefully aware that there are issues with using serial-to-USB as the data transfer rate is HIGHER with USB, and sometimes the MAP can't keep up.
The Belkin adapter is what most us Supra guys use, and it works 95% of the time.
You can get them @ Circuit City.
Hope this helps.
EDIT:
I read that you already got one from Circuit City. Sweet. Don't waste your time or $$$ on a PCMCIA adapter.... while they work " better " they don't work $150 better.
Also, if you're having off idle and/or throttle response problems, change your TPS enrichment. It's around 20-25% I believe, for safety. Taking it down from there to 7-12% should help.
I have the same MAP in the MKIV, so if you need any tuning help, let me know. Staring at a wideband and street tuning a leaf-sprung, high-hp, 35" tire rig is neither fun nor safe.
Best of luck to you.
