Just completed an Avital 4113 remote start install on a 2006 F150. I ran the tach wire, however the system powered right up on the first try with the default setting of Virtual Tach. I have since started it successfully about 6 times with no issues at all- no over-cranking or stalling. Let it run for 10 minutes with no shutdown and it is quite cold here today. Before returning it to the customer, I was wondering what you all thought about leaving it on Virtual Tach? Just nervous about the dreaded follow up phone call with issues. Thanks

I only do it as a last resort. I always use the non-common injector wire.
I've had a car here and there not start by using virtual tach....so just stick with the injector wire. It's not hard to do. Using virt tach is just lazy in my opinion.

its not that bad to be honest I would never do a tach in new GM because its a waste of time never had a problem with GM however on fords its a must and even with the tach theres still one or two that give me issues I try to do tach as much as i can lets not forget the car that the boss takes 2 hours before we close and you still have to finish the car your working on that leaves you with only one hour to do a RS virtual tach reliability? -- posted image.

That is true, on some newer GM's, as soon as the car see's ignition and accessory powered, it automatically powers the starter. So with that, you don't even have to connect starter or tach.....technically.

How does the R/S handle this, when the vehicle fails to start properly? More over, how does the vehicle handle this, when it fails to start properly?

Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.
Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?
Moral - Never dismiss the obvious.

loneranger,
There's a good post on here somewhere, from a year or to ago......search for something like "tach vs. voltage sense vs. crank time."
For the record, I've had DEI's virtual tach in my 5.7-liter, 112,000 mile, '96 Roadmaster wagon and it works great. I would imagine it would be even better in newer cars.
I also have Audiovox's "crank averaging" voltage sensing system in my 147,000-mile, 3.8 liter '96 Camaro, which also works well.
We've had temps down to the teens here in New Engand, too.
All the manufacturers seem to be improving their tachless technologies all the time.
