Heeeellllp,
I've got a zx300tt and use a Blazt ECU interface cable and software
(Here is the website http://www.4-your.com/nissan/interface_cable.html )
for fault finding, maintanance and tuning.
This replaces the factory Conzult 1 diagnostic unit and works really well.
I can connect it to my laptop and fault find while i get someone else to drive.

The Question is,

Is it possible to use a conzult 1 on the D21/Frontier?
I note the connector is different, but if the consult 1 works is there an adaptor available?

Thanking you in advance

i would contact the company that produces the unit before attempting to hook anything up to a vehicle for which it is not intended.

Thanks Patrick, Yeah I agree.
The Cable and Software can (and was designed to ) work on 300 ZX's, Sylvias,Pulsars etc - any nissan
that will work with a Nissan Consult 1 diagnostic computer.
The problem is that Nissan don't want to tell me weather the Nissan D21 ute 2.4 Petrol can be diagnosed with the Consult 1.

Can you help or point me to some one who can tell me, Please
Thanking you for your help in advance

perhaps look on the case or directions of the Consult 1 unit, and look for a contact number? im sure that if it will work, the company will tell you, or could provide you with the info of what you have to do to make it work!
