Nistune Forums

Hello all,

After I tuned my car in early July this year with Nistune, it has been runnign great. However, yesterday, I tried to reconnect NIstune thru my PLMS USB consult cable and it just wouldn't connect at all.

Since I successfully used Nistune the last time, there has been NO change either in my laptop's configuration (that I can think of) or in the car's wiring.

Here is what happens. I connect the consult cable into the consult port under the steering column/dash of my Skyline. Then I connect the USB plug into the USB port of my laptop and the red light on the consult cable lights up. I start the car and the Nistune software and try to press the CONSULT button. I get the following message in the bottom left corner of the Nistune screen:

Consult not connected!! COM1 spare: COM3 spare.

And while I get this message, the green light on the consult cable flashes quickly a few times and then goes off. Now I am stumped. Is it the cable? Or is it the chip? Or is it something else, like the new version of the software?

I sent Matt a few log files of when I tried using this (a) with the May 2008 version of Nistune and then (b) with the latest version from July 28, 2008. Both have the same result. Hope he has an answer for me. I am still attaching them here again.

If anyone else can shed some light on this, I would really appreciate it.

Thanks,

We have so far established that Nistune is attempting to talk to the ECU (green light flashing on consult box) but no response from ECU (orange light flashing in response)

Either problem with ECU (running limp mode - flashing LED on ECU and vehicle not running well) or consult cable receive circuitry

Suggested trying cable out on another Nissan to check that and also check ECU leds to see if running okay
