Sup guys. I'm a little confused with which method is best for datalogging.

I'm trying to get my engine management setup before I order all my parts for my turbo project. Right now I have:


96 Integra LS
Chipped OBD-1 P75
OBD2-OBD1 Harness
Nasty laptop

I burned a 27C256 with a basemap, put it in the new ECU, and started the car right up... No problem.

Anyway - I'd like to put my 450's in and start tuning them for my NA setup just as practice for when I go turbo. I wan't to set my ECU up for datalogging with uberdata. I've heard of several ways to datalog.

My laptop has both serial and USB ports so I'm inclined to go with which method is easiest and most reliable.

I've heard this is the most plug and play method out there? It looks like it just plugs right over the connector on CN2. Anyone use this cable?

Still will need to solder a 4pin header into the CN2 port with that Superdroid cable. Either way you'll be soldering to CN2, so it's really up to you which methid you preffer. I've tried the USB cable and it didn't work out so well because I was using a USB adapter card
But I'm now going to try the Serial type because i know for sure that will work.

Kowalski

Is that all I have to do? Where can I get the header.

I am personaly partial to using the cell phone cables w/ usb. You have to only solder 3 freaking wires to the ECU.

This is the exact cable I used

Yeah same here. I have one I can sell you if you need it. Only reason it didn't work for me is because I have an old wrinklyass laptop that was unwilling to cooperatu with the USB devices :P Real easy to wire up and get working though if thats what your looking for.

Kowalski

Is there anyway you can solder the 3 wires to a female connector that plugs into the CN2 Connector?

Sorry for my newbishness, I'm new to this stuff but extremely interested.

I'm going to radioshack tomorrow to try to get the cable - if they don't have it ill buy it off of ya man.

[Edit]
Lemme clairify because I think I'm making an idiot of myself...

My ECU has a white 4 pin connector soldered to CN2 slot shown here:

Is this connector something the previous owner put in or is it how the ECU came?

It looks like that RS232 to TTL Converter would just plug right in or maybe I'm just retarded.

Go to our Forums and ask your questions there if you want. I am partial to the Nokia cable setup as well because of the USB. EIther way, you are going to have to solder onto the board.

Here, I went and took some pics of my ECU:




So, will the TTL connector plug into that or do I need to remove the white connector to make it work?

projekteg

your ecu has already been prepped for data logging, that's weird. either way, the max 233 doesn't just 'plug' up. the corresponding wires aren't in the correct order from the converter to the ecu, so you'll have to do some soldering on one end regardless.

Kowalski

Yeah I bought the ECU already chipped by Phiz. I already sent him a message asking him what cable he uses but I wanted to see if anyone here knew.

Thanks for the replies guys.
