I've gotten a lot of questions about what exactly this consult stuff is, so here's a quick short summary. 'Consult' is the name of the machine that Nissan dealerships use to 'talk' to your car. The 'consult port' is the grey connector below your fuse box that the machine plugs into. This is similar to the OBD-II connector on later cars. Both B13/S13 and B14/S14 have a consult port (even the B14/S14 cars with OBD-II ports, they have both!), up to 1997. In 1998 they switch to the consult-II, and I do not work with that.
So what does all that mean to you?
Well, some really bright guys reverse engineered the way a consult machine communicates to the ecu. The end result is that with a little electronics hardware people could write computer software to talk to the ecu instead. Cool. What does that mean? Well, besides being able to dump the stock rom from the ecu, you can do cool stuff like datalogging or put your car in timing mode with the click of a button. Neato! It really is just that cool.
So what is this daughterboard with consult stuff?
There are two hurdles with interfacing your laptop to the consult port. First, you've got to have a little electronics. Second, you've got to have the physical plug that plugs into the socket. The daughterboard with consult tackles both those by including the electronics on the daughterboard, then giving you a standard serial cable out the back. You plug this cable directly into your laptop, no further stuff needed (unless you need a serial to usb adapter of course).
What consult software is available for free? For a little money?
Uh, I'll make a list later. If you guys post the site for software I'll add it to this post. There's a bunch.
No, if your using an early B14 ecu the consult for it is Consult-I and the above software will work just fine, assuming the connector is present and pinned out the same.
Consult-I or II is ecu dependant, so your JWT ecu is Consult-I, but you need to check the wiring diagram for your car to see if the consult pins are pulled out correctly to work with it. Worst case scenaria, I could (or you could if you've got the skills) build a harness inside the ecu for the consult pins.
I have a '99 Infiniti G20 with a bluebird (highport) engine. I have a JWT B14 ECU controlling it.
Since my car is newer than '98, does that mean I have the newer consult-II port and can't use this even though I'm running a B14 ECU?
I just got my Blazt cable and software tonight. For some reason my license key won't work so I haven't been able to run the software. I did download Conzult though, and....
DAMN!! This is awesome. The most fun I've ever had in my car sitting still (almost). It's really cool to sit there and watch what your engine is doing... even with semi-functional trial version software. If you don't have a consult cable, software and a laptop then you're missing out.
I got my 'Nissan Data Scan' and 'Log Viewer' software working. Initially they had spelled my email address wrong, so that's why I couldn't register.
While I'm posting, Can anyone recommend good OBDII consult software? The OBD ScanTech that Calum listed stated that you HAD to use their specific cable.
Dunno if this is the correct place but i need to find out this:
Can i run CalumSult with my NissDataScan in rs232 mode? and should i get a 9 pin male (both ends) rs232 cable or a 9 pin to 15 pin? or would the cable depend on what my computer takes?
TIA,
Tony....

u should be able to, the cable ur after is just a normal straight thru serial cable, if u mean one to get to make it reach the serial plug on the device u have

Thanks for the reply, i`ve been told at my local IT accesories store to get a 9 pin male to 15 pin male serial cable as the most common spare serial port on computers is a 15 pin!
But now i`ve seen a 9 pin male to USB male, would this be an even easier option?
maybe on computers made 25 years ago they were 15, but theyre 9 now
surely the logical thing to do would be to actually take a look at what u intend to ghook it up to, making sure u dont confuse any vga output with serial. if u have serial, it will be 9 pins
Speed limiter without remapping= find the green & yellow wire. Eighth down on the left in the harness plug at the ECU. Number 34, I believe. Snip and tape the ends.
The speed-o will continue to work.... Nothing will be effected except the speed limiter.
has anyone confirmed speed is not used for anything else? eg ive heard as many people say its used for fuel economy (ie when ecu decides to enter closed loop mode?) as those who say its not used for anything except speed limiting.
It is used for fan turn-on temps for some ecus. I'm not sure if it affects the closed-loop decision, but I wouldn't be surprised if it does. It doesn't affect the WOT performance.
