today my cel came on and it's reading code 10 (i think). I've got neptune, and i checked it the way your supposed to with the key in the on position (car off) and throttle past 65% and nothing happens (no cel appears). When i start the car again the cel is gone, but if i drive it for a bit it'll come back on. It blinks while i'm driving (one long pause) but i'm not sure if i can go by that. I don't know what's going on with my car today. Can someone shed some more light on this subject?

 

not to shure , but if you have datalogger you can read the codes with that , sorry if Iam not any help but I would also like to know ???

i never installed the cable, so i don't do any datalogging.......but that's something to think about in the future when i get retuned.......

 

9 times out of 10 you aren't experiencing a code 10, but a code 1. The code isn't retained after you key off. That's why when you check it it's not there. James (NepTune creator) addressed this issue several months ago and released a software update. If your tuner left the car in closed loop you either have a wiring problem (signal wire has a break in it) or your o2 sensor is just bad. If you are in open loop, then most likely the version of NepTune that you were tuned on was before the fix.

 

spoken like a TRUE pro...

my car was tuned by stoopid about this time last year at jason hunt's shop. So i guess i need an update.

 

even if i'm in open loop, i probably still need an o2 sensor, right?
