Vinci Handheld prgrammer
I'm removing my A.I.R piping,and blocking off the flange at the header.
Can i change the A.I.R bypass setting?I would like to give it a temp setting of -10* so the air pump doesn't ever come on and no codes will be throw.
Thanks for putting up with some my questions bro..

I am not adept at tuning, but I am willing to learn. The thing is I don't need to change alot and the Vinci tuner would do everything I need, except that I would like to leave my car in overdrive if possible with my stall. If not then I would like to leave it in 3'rd and have the clutch lock up earlier.
Again, thanks very much.

If I would get a programmed PCM, would I still be able to use the VHP to modify. Will it read the program in the PCM as a base program(stock) and still allow me to make changes?
Is there a fix to that?

Key on, then insert VHP plug as recommended in manual.
No no radio, door, lights etc.. all are off.
Battery seems ok but I'll get it checked soon.
Could that have something to do with my car being an import and not having O2 sensors?
Or dust in the PCM plug?
It accepts tunes but only after all these scenarios.
Changed the battery and did a "cold" tune, but no help.
It took me 1 hr 45 min to get the program to finally work.
Just to give you an idea of the ordeal.
Following procedures to a T.
log on tune, press yes to start tune and there it goes. Randomly it gives me errors, most common is 73 and 63 then I got 62, 69, FF you name it.
Once I get an error, I turn contact off, remove plug, put contact on and install plug.
Now the handheld has to have the stock program back in, and again errors.
So do it again, and again untill it accepts the stock tune back.
So here we go again, it downloads the stock tune (no problem in dowloading) and back to custom tune. Only to get another error (not always at the same spot) and the hole scenario has to be repeated.
Like I said 1 3/4 Hr later it finally accepted the custom tune.
I don't believe it has anything to do with my car, something must not be right. I still have my Hypertech III and out of curiosity, when I had my car back to stock tune, I used it to see if it had anything to do with my PCM. Well no my car accepted Hypertech tune right away, just like it used to do when I used it before my cam and injector change (which rendered the Hypertech worthless).
Has anyone else using VHP handheld encountered something similar???
I'll double check. But after today, I'm in no hurry to change any tuning.
· Before attempting to tune the vehicle, assure that the battery is fully charged. We have had several instances of the vehicle not accepting the tune. Discussions with the vehicle owner have caused us to suspect a partially discharged battery or poor battery terminal connections. This will cause the tuner to lock-up during the tuning procedure.. In most every case, once the battery was brought up to full charge, the onboard computer accepted the tune.
· If the tuner locks up during tuning, turn the key off and remove the tuner cable. Double check battery condition and assure that all electrical devices are turned off in the vehicle and all of the proper fuses have been removed. Turn the key on, install the tuner cable and try again.
What do they mean by remove all proper fuses???? Am I missing something here.
