ok im helping a guy out from another forum, he is designing a program that will be free to download, it will work sort of like the Nissan Consult system u just have to buy a cord that will connect to the plug in the fuse box and make a USB harness. But the readings picked up from my car seemed a little funny to him so he wants to know the correct stock numbers.

my base ignition was jumping from 5 to 7 to 11, it ended up bouncing around 7 and 11 when the car warmed up

and my throttle position sensor had a reading of 38

from his experience he has a 300ZX the base ignition should be around 20 and hold steady mine bounced like a basketball, that was the main concern, the flaw could also be the program itself but we will not be able to tell unless we play around with it. my car is in perfect working condition and is not throwing any codes. If some of the 4th gen gurus can tell me what the numbers are suppose to be that would be most helpful.

i will get more details up about the system when i can, but what i know about it so far is, it can read all the sensors on ur car i.e. O2 sensors, water temp, ignition readings

 

Nobody knows?
