Data Scan for Skyline

[dajorad]

Tom,

how do you plan to get the data? Do you have the protocol of the consult port?

[x2shy]

Rs232c protocol.

Kinda standard for most data transfer systems. car -> PC.

[TomR33]

No, it's not really an Rs232c protocol.

I have writen by now 2 applications that use the consult protocol: Data Scan - for monitoring and logging a real time data and Rom Reader - for downloading the ROM data.

The Data Scan is especially good for diagnosing faults and those flat spots. You can see some of the logs that i have done here:

Very smart. The data is there if you know how to get it. Are you planning on giving the software away to other enthusiasts?

[Guest RedLineGTR]

a had a thread a while ago...someone emailed the guy that created the program etc for the 300zx and said he didnt see why it wouldnt work with a skyline..thats about how far we got with it.

[dajorad]

Tom,

where did you get the protocol from? Reverse engineer it?

I have designed a logger that records rpm, speed, injector duty, advance, air flow etc, but I did this by monitoring the pins of the ECU as I do not know the consult protocol.

[TomR33]

dajorad: Yes, I've reverse engineered it, bought the CMX-100 from Techtom and went from there, lots of work.

[dajorad]

The CMX100 looks like a cool little unit. But it measures just 4 parameters. I presume you had to 'guess' the format of the commands to get the other parameters based on the commands from the CMX100.

What are your plans for the software you have written?

[kjb_r33]

HEY, i have a consult sitting here, but the damn thing is all in japanesse, any idea which buttons to push to convert it to english???

[skyline33]

kjb, do you wanna sell it to me??

[Muz]

How do I get one of these? I am very interested in the Conzult software for Skylines when available. What an absolutely invaluable tool.

Cheers

[kjb_r33]

realistically, whats it worth?

[siksII]

someone on the aus300 forum has a nissan consult unit, every1 uses his one on meets.. just go on a 300zx cruise and scab if you want data

[NRB]

Tom, I'd be interested. Is it only for a factory ECU, or would it work with a PowerFC also? I've got an old laptop I'd like to use for this sort of data aquisition - quite important on track days I feel.

[paulr33]

Its for the factory ECU. It plugs into the diag port on the r33 and then connects to the laptop. The conzult software then translates all the responses from the diag port into stuff on the screen, much like the screen captures from the 300zx-twinturbo site.

The 300zx guys tested on an rb25det and it didnt work.

So their site says anyway:)

The only thing stopping you from doing this yourself is

1) you need the plug so you can plug your PC into the conzult port _ well i guess you could guess the wiries and make a custom plug

2) you need the software that communicates with the port - 300zxtwinturbo wanna sell it for $600 a pop and that include a cable to plug into the conzult port

nissan have a hardware version which is worth around 19k brand new. you cant buy nor can use it. its like the hand controller for the apexi powerFC, similar concept, all handheld changes and stuff, no need for laptop.

TomR33: Can you help out with 1 or 2?

[siksII]

Maybe the guys on aus300 just dont wanna share, i hear the owner of that system on the forum is not the friendliest guy.

Im meeting up with a good mate off the 300 forum today, ill ask him i know he has used conzult system on his 300ztt

edit:forgot to add that there are LOTS of similarities between vg30 and rb series engines, in terms of electrics, sensors etc..so id be surprised if it didnt work...

[paulr33]

Yeah this could be true also. I can't see any reason why it wouldn't work but im not exactly an electronics engineer.

[paulr33]

Albeit its mainly only used for fault finding and the like. Shows sensor failures and their values. Yes you could data log the 1/4 mile etc but not sure how useful it would be on a day to day basis.

And here is a link to a brief CONSULT explanation -

I've been doing a bit of research on it recently, as it sure would be usefull...

[paulr33]

Any updates?
