I feel like a dummy but I cannot get my computer to see my s300. I have an account on hondata's forum but I do not recall my user name, and all the ones I guessed were wrong. I emailed forum@hondata.com like it said to on the register page, but I got a delivery status notification error. I tried to re-register under a different name and got this error:Ran into problems sending Mail. Response: 535 Error: authentication failed

I have an OBD1 GSR ECU socketed by a member on here, with an s300 from vendor on here also. I installed the latest version of SManager from hondata's site, and ran the upgrade USB drivers with no luck. When I use the Test USB feature, it returns an error that something is wrong. There is no LED illuminated on the board, nor does the computer pop up a 'new hardware found' dialog when I turn the key on. The CEL remains solid once I turn the key to IGN, so I am pretty sure the ECU is seeing power.

What factors could make this happen? I would like to think my ECU is good, I pulled it out of my own (running) car before it got chipped. I have a laptop with XP on it, and I am admin on it. I do not see the Hondata within the device manager.

I checked the ECU fuse, and I checked to make sure my main relay is grounded. Anything else? Feel free to chime in anything, including shorts in wiring. I redid some wiring in the interior but I stayed away from the harness with the ECU on it.

Please help!

Thanks in advance

When you turn your key to ign2 the board should have a green light. If it doesn't, the socketing was not done properly.

Thanks a lot for the reply, it certainly helps.

I will double check my chassis wiring and make sure the ECU is getting power. The ECU gets power on the yel/blk line, from the main relay... correct?

I checked the ECU fuse with a meter and its got 12V across it when the IGN2 position is active

bump - any troubleshooting ideas? I cannot register on Hondata and my tuning appointment is slowly approaching

If the ecu worked before you sent it out... and now it doesn't... it's most likely a socketing issue. If it's not, you have an electrical issue somewhere.

With the key at ignition 2 (the position before you start the car) there should be 2 green LED's on the s300 board that light up.

I cannot accurately say the ECU worked right before I sent it out. The car ran two years ago and has been sitting since. I took the ECU out and shipped it off for socketing.

edit - hit enter by accident.

Where can I probe on the Hondata board to make sure its getting power? Would it be a wise investment to purchase the socket tester?

that would be a good ECU

Unless the car filled with water and u turned the key on or something crazy dumb like that,
But if it just sat, im willing to bet ur ECU was good.

I really doubt the ECU was socketed incorrectly, I sent it to a very reputable member on here I am ESD certified and sent it very well packaged in an ESD bag, but who knows... maybe somethin heppened

argh!

have you tried a different laptop? see if you can turn your up your virtual memory and close all of the programs that run from start up. also have you tried plugging in your laptop during an engine start up? hope something works

I got it... I feel like an idiot.

I went over lots of wiring diagrams and finally probed the correct wire. There was a short between one of the ECU grounds and chassis ground. I jumped the pin to ground and it worked
