DIY: ECU Scantools/Data Cables

[michaelw]

Diagnostics only. The VY definition files are pretty limited at the moment but go take a look at www.efilive.com and download version 4 to give yourself an idea as to what you can get.

There should be enough info in this thread to roll your own and I can sell you the plug if you want. If you want to buy then take a look at the following thread USB -> VR/VS/VT adaptor

[Degeko]

yeah im interested in the plug, the efilive4 does support vy v6, how would i go about remapping?? do i need to replace rom with eeprom like older cars?

[michaelw]

If you want to remap you should speak to DrBob. The ALDL cable will do diagnostics only.

I'm going to have a go a making a cable to use on my VR.
Is this the correct plug I need ??

LINKY -->JAYCAR CAT # PP0720

[michaelw]

Yes. That is the correct one. I didn't know jaycar were selling them again.

I think jaycar have brought them back, noticed them listed in this years catlogue the other day. I think they are double the price you are selling them for anyway arent they michaelw?

O CRAP !! I just ordered 1

I advise everyone just to get a complete setup from michaelw. He does them at a really good price and the whole setup is professional. Fits the whole circuit into the connector, usb ready. When he can do them for the price he does, its not worth doing it yourself.

Have bought the kit from Michaelw, and have been able to get it to work; however, it seems to cut out after a few minutes and the live dashboard doesn't seem to work, even when logging shows that it is recording live data (for a short time!)

Any ideas what I should try, or is this normal?

Cheers,
Brian

I also got the cable from the good man. It's works fine. But EFILive V4 evaluation does seem very limited in what it can do for me. I got the Dash screen up but it would only show the items in the pic below. While using it I found it would set the thermo fans off and raise the idle, I would have to use the clear DTC button to turn them off after viewing the dash readouts live. I'm told the full version may give me more usable dash readouts.

Hmmm, thanks for the info - I get the beep & the usual warning lights flashing, as described in the "readme"'s.... but I can't even get those gauges working - nothing on my EFI Dashboard responds, only a few of the the raw data & graphs, & I don't think there is one for engine timing... may be because I have a VX? I guess I'll have to wait & see what other feedback there is....

[michaelw]

So it displays data for a bit then shuts off? The logging on the trial version of the software is limited to about 20 seconds. But you should be able to get live data. When you select the engine data macro and then go aldl->start what does the tab for the dashboard display?

The vx does not have too much data on it at the moment. but you should get some sings of life. If you have no joy I will sort something out.

[michaelw]

As the trial version is limited, you cannot display many graphs at once BUT you can change what is displayed. Right click on an active graph and then follow the menu to get what you want to read.

G'day.
Just wondering if I supply the 16 pin plug and any other needed supplies coukd you make a aldl to usb cabke for me, I used to be ablr to do this kind of stuff myself, but my nerves are shot and I shake too much to solder now.
I am looking to run a linux backend off an old lappy to run gps, mp3, and diags, and maybe sum old skool games

Hi...I'm having trouble getting the codes with the engine light. I inserted the paper clip into pins A & B in the diagnostic plug, turn the key to on (all the right things light up), the engine (thermo) fan comes on, but the engine light doesn't come on, so there is no flashing codes. Is this a common problem?...could it be something wrong with the ECU? I thought if there was a problem with the ECU I'd get a 55 code, but its hard to get that when the engine light dosn't come on. With the paper clip out, the engine light will come on when car is first started, but goes out with the battery & oil lights once the engine fires. Any and all help needed and appreciated.

A question about the Jaycar plugs....

I've noticed that internally there is a link between pins 4 and 5. I've had a look at the connector in my VZ and it looks that both pins 4 and 5 are used.

Question is - if I plug this Jaycar plug into the socket I'll be shorting these pins together in the harness. Is this going to blow something up? Or is this connection necessary to establish comms??

Any help much appreciated. Thanx!

[ren11000]

pins 4 and 5 are earth wires

[jet-6]

Can you make your own scan tool for a VZ with a Alloytech?

Id love to own one so i can see the codes/faults

EDIT, i have seen complete handheld units on ebay, do they work?

[jet-6]

Bump this thread up, ive been looking into a complete scan tool, these are the two that impress me the most:

U581 CAN Trouble Code Reader OBDII/EOBDII Memo Scanner - eBay, Other Car Parts, Accessories, Car Parts, Accessories, Cars, Bikes, Boats. (end time 28-Jan-09 10:45:00 AEDST)

and

eBay Motors: OBDII EOBD Scanner Tool CAN-BUS OBD2 Reader GS500 (item 260350550151 end time Jan-24-09 13:02:22 PST)

What do you guys think, or am i better off using a lead and my laptop(has to be USB)

Unless you can do more stuff with the laptop id rather have the handheld unit

So any ideas would be great right about now

[michaelw]

I have not had the time to look into CAN OBD yet. There are DIY units but I haven't built one yet. I suspect that the CAN handheld will work but it would be a guess. The Alloytech runs OBD CAN so the ALDL and OBD VPW described here won't work.

whats the best software and can i use the vn lead with a different plug to run a vr?
