So I purchased one of those Consult USP boxes on Ebay with "Nissan-14" on it, downloaded VCP drivers for it from FTDIchip.com. All seemed to work on my Windows 7 laptop, and when plugged in to the 300zx TT. Connected ok (COM 9) and went through all the steps of choosing gauges to display.
Everything seemed fine- except for one anomaly. It would not show the speed. I tried both imperial and metric (mph and km/h). My speedometer is working perfectly.
Once I started driving with the laptop plugged in, about a mile from my home the power steering suddenly stopped working, and within a minute the HICAS light came on. I pulled codes, it said I had a code 14- vehicle speed sensor circuit error.
After a shutdown, everything seemed normal. Drove a couple blocks, HICAS light came on and the power steering went off again.
Unplugged the consult box, shut down, restarted and drove 4 miles home- no problem at all. No HICAS light, power steering worked fine.
Now I am a little nervous about doing a full boost run with the laptop plugged in trying to find out what causes it to go into safety boost when I hit 11 psi. If I am going to lose my power steering every time I have this running... that doesn't inspire me to try 90+ mph runs.
One thing I did find was that the MAF is definitely sending bad signals in the ON position (engine not running). My logs show it was 0.08 volts- supposed to be 0.8.
Anyone know what the deal is with the speed sensor when a consult plug is running?
