Hello,

Ok, I have wired My PLX to ECU.. Red wire to A25, Black to ground, White to D14.
When I turn on igniton my wideband starts working and everything is ok.. But Now I need to use datalogging in crome..

Here is what I've done to my ECU:



I'm using Ostrich BTW..

When I start crome and select file>settings>real time programming and choose port: COM4 and in hardware type choose: Moates Ostrich and press Test Connection it connects succesfully. And Put>Get works OK. But when I go to file>settings>tuner comm and select Crome QD2 and port: COM4 and press test connection it says: COM4 failed to open.

Can you please help me with this? I need to start datalogging asap.

Here is another photo:

 

Is that a USB -> Serial converter wired to the ECU? I can't see any little box in the middle of the cable that would indicate it has a conversion chip. Also, it sounds like you're trying to connect to the ECU with the same COM port as you have your Ostrich on. The datalogging connection should be on a different port.

 

aha.. so I should have a conversion chip.. I didn't knew that.. So I have to buy HondaLog or HULOG from moates right? But the problem is my laptop has only one USB port.. which I use for ostrich.. How will I use HULOG or something ?

 

The datalogging part will only connect successfully if you have the ecu up and running. IE: The car started or ignition on position.

So if you have the car running and it doesn't connect, then you want to verify your settings and driver.

I believe you can use a USB spliter/hub to run two things into the same port. I am not sure how well they will work though.

 

Yes, either HULOG or Hondalog will work. A cheaper alternative is to find a cell phone data cable for $10-15 and hack it apart, find the Tx and Rx wires, and connect that to the ECU. If you only have 1 USB port, you can get a regular serial adapter and wire that to the ECU. Both methods are detailed on this page:

If you still want to datalog through USB, you could unplug the Ostrich while you datalog, then switch the cables to upload your changes. A small USB hub may work as well, but I think when I tried it it couldn't supply enough power to both devices at once.

 

Ok, thanks guys..
I already ordered HULOG and USB Hub.. Is this everything I need?

 

What usb cable is that ?
Is j12 removed on the ecu ?

 

so you're using crome to tune? don't you need crome pro to datalog?

 

Do you have a serial port? Use a superdroid cable. You need a datalogging cable. A straight USB cable will not work. I've used both Moates and Superdroid datalogging cables and both work extremely well.

 

those cheap usb to serial converters from bestbuy sold under the dynex brand work flawless
im using the ttl to serial converter from xenocron with the dynex brand usb to serial converter

 

Yeah, I'm using Crome PRO

 

a very succesful thread.

I will be using alot of this info
