Can someone explain when the tach options on this remote starter are used? It has tach, DBI tach, voltage & hybrid.
I'm used to using the negative tach signal that gave me no problems no matter which car I installed a remote starter on. Now....I'm feeling obsolete!
Someone help please.

Tach = hardwire tach usually AC voltage from coil or injector.
dbi tach = stands for data bus interface tach. (bypass must support tach output from vehicle data)
Voltage = voltage sense as standing battery voltage is usually lower than sytem voltage when running.
Hybrid = compatible with hybrid vehicles.

If I decided to use the voltage option instead of tach would I connect the tach line to the battery?

In a word don't use tach voltage it's unreliable especially when the temperature drops.
What vehicle?

No not for voltage sense at least with the DEI Brands.

2012 SF 3.5L V6
Only reason I'm opting to use the voltage is I have the OEM remote start and don't want to run the line to the injector or ECM (its bolted onto the air filter housing). I've tried using the tach line for the factory remote start but the Prestige doesn't sense it for whatever reason so I'm opting to use the tach voltage. My first remote start used voltage and I had no problems with it.
Actually the alarm died years before the car did! Granted it was a 94 Protege and isn't the same as a 12 SF but I'm sure the electronics have improved since then.

Just to clarify you are doing the Prestige tach learning proceedure when using the factory tach wire?
If vehicle requires a bypass, Does the bypass you are using have a vehicle data to tach output?

Prestige kit isn't sold in the UK but a customer brought one over from a US trip for me to install in a Range Rover. I tried 4 KNOWN tach signal wires, none worked. I went to an injector, still nothing and it wouldn't go into programming mode. In desperation there's an external trigger wire, blue/black(?). I grounded it and everything seemed to come together.
I've since noticed a couple of posts on Prestige R/S with people having similar problems.

Yes, I tried multiple times but get no response from the module that it learned the tach.
The factory remote start is a plug & play except for the tach, key sense, and dome illumination. The install manual for the remote start specifically tells you the GREEN/ orange is for the tach so attach it correctly to prevent damage to the starter. The factory remote starter works correctly so I know it's connected correctly.

hmmm
Interesting. I will try that and let you know how it works.
Thanks.

Tried grounding the ext trigger but still no go. The only thing I haven't connected is the key sense. Still can't program the tach. Does anyone know if key sense has to be operational for RS to work?
Also, is there anyway to reset all the features back to default on the APS997c? Was programming the options when I lost count and can't figure out what I changed.
Thanks.

What voltage AC does the tach wire read with a Digital Multi Meter. Red probe to tach wire black probe to ground.

The manual dosen't list a reset method if Audiovox won't tell you how you will need to go through all the settings 1 by 1 to verify proper settings.

You can try this:
To reset your prestige remote start, first get into your car with your starter and ignition key and leave the driver's door open. Now insert your key into the ignition and turn it to the "On" position. Then press and hold the "Valet" button on your remote and wait for the horn to chirp. Now press and hold the "Valet" button again and press and release the starter button on your remote. Wait for the horn to chirp again and release the "Valet" button to end the programming sequence.

Any one else noticed a plague of questions/problems that seem to have arisen with A/Vox/Prestige/Code products recently, mainly tach and programming?

I have a very old multimeter so no AC but it does have a low and high tachometer. I tested the OEM RS tach line and nothing, that explains why the Prestige doesn't get the tach signal so I tested the ODBII connector and got a signal on the orange line however it's way off: idle was reading at ~1500 rpm so something is wrong with that. Next I tested the diagnostics connector under the hood and viola it works! Now I need to figure out where that line goes to and connect to that! RS used to be so easy to install....I miss those days! LOL

Did you mean the valet button connected to the module?

Yes, that's what he should have said.

If the tach wire that you got the 1500 rpm from changes when you idle it up then the brain should be able to learn it, and work for the remote start.

And it should be implied that the only valet button we should be concerned with is the prestige one as you can't reset it with any other valet button. So c'mon now common sense people!

No disrespect to our poster but common sense?
Here with DIYers?
Do me a favour how many times do you just want to ask if they've read the install guide at all?
Or can they read enough to spell?
From some posts you wouldn't think so.

Give a man a fish he'll eat for a day, Teach him to fish he'll eat for a lifetime.
I'm here to help not teach color by number's for remote start and alarms.
No disrespect but that's just my outlook on what I'm trying to provide here!

As you know I absolutely agree with your philosophy but we must draw the line between hand holding and thinking for the OPs and concise instructions.

But there in lies the problem who dictates where those lines are and what constitutes those lines? Do you consider each post as a new post or is it linear across the title subject. When someone says that they have done tach programming and settings changes you must assume that they know what valet button you are reffering to. Otherwise you end up with the shotgun approach when a single pin brick would surfice to accomplish the goal.

The answer my friend is that it's a thin line between thoroughness and obsession!
Most good pros will admit they are almost OCD when it comes to their work so the points have been made lets call an amicable end to it.

In my defense I say...don't assume, it makes an ASS out of U and ME.
It's a quick simple yes or no question to ask not to mention I stopped installing professionally over 15 years ago and this is my 1st install in 6 years. So I know I'm obsolete.
I know a lot has changed so I'd rather ask a simple question than try for 3 hours racking my brain trying to figure out what the hell I did wrong.
I ask for some leeway from someone that's out the loop and thank everyone for their assistance and time.

To Ken Audiovox Tech services, set set up your own password and press icon at top for manuals.
To krushmoto, no offence meant and none taken, ditto to Lurch we don't know your levels of expertise so my attitude is to assume the worst.
Please keep asking when in doubt, naught (nought?) wrong with your questions.
