EFIliveV5 vs ATap
Re: EFIliveV5 vs ATap Atap is a scan tool that works with GM, Ford and Chrysler OBD-II vehicles. It does a good job displaying generic and manufacturer enhanced data and trouble codes for GM, Ford and Chrysler. If you want to see trouble codes and log a data for GM, Ford and Chrysler vehicles then use Autotap.
EFILive is a specific purpose scan tool designed for GM vehicles and in particular the LS1 platform. (Future versions of EFILiveV5 may support other GM powertrains and Ford and Chrysler).
EFILiveV5 has two advantages over Atap:
1. It can log high-speed data, up to 24 paramters at 10 frames per second. Atap does not.
2. It can perform bidirectional controls - you can temporarily override powertrain control values like idle speed, IAC position, Spark advance, Air fuel, gear selection, TCC lockup and about 20 others. These controls allow you to make adjustments on-the-fly while running on a dyno.
As an added bonus, the AT1 (and AT123) interface that ships with Atap can be used with EFILiveV5.

Re: EFIliveV5 vs ATap EFIliveV5 look like a very promising product. The competative upgrade option of paying $95 and using my existing AT1 interface is very attractive. If I use my existing AT1 interface, do I still get the superior high-speed data logging?
Re: EFIliveV5 vs ATap yeah, what Roberto said! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I want to know this as well, any performance difference with the AT1 connector?
also, exactly how fast is it? I think atap does 20 samples per second

Re: EFIliveV5 vs ATap EFIliveV5 - All your benchmarks are with the old cable and old software for Autotap correct? The new upcoming Atap software/hardware should fare a bit better. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Hang in there folks, Atap not done yet. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

But to be fair I was comparing apples to apples. The comparison was to indicate what performance gains an existing Autotap user would get for $95.00
EFILiveV5 also uses (and recommends) the new LDV100P1 and LDV123P1 B&B hardware - however, with the right software the speed difference between the old and new hardware is almost undectable.
However, I agree that new interface from B&B is much better, in many ways than the old AT1 interface.
I cannot comment on the speed difference between the old Autotap software and the new Autotap software - I have not seen the new product yet.
The data speeds that I have quoted (for EFILiveV5) cannot be speeded up with hardware/software changes because it is the PCM that is limiting the data transfer.
(Unless the interface/PCM supports 4x mode)

Re: EFIliveV5 vs ATap 10 samples/sec is pathetically slow for a datalogger. Good dataloggers will do 20,000,000 samples/second.
There's no excuse for either piece of hardware working at anything less than the maximum speed the Computer/OBD-II bus supports.

Re: EFIliveV5 vs ATap I'm confused, I just ordered A-tap from the pace parts GP. I got the one that will scan all gm ford ect.
So for 95$ I can get the EFIlive5 and use the A-tap cable so I would be able to run both EFIlive5 and A-tap if I so chose to do that?
Can someone clarify I work too much, my brain shut down. Please excuse my ignorance. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

Short of hooking up your own sensors connected back to a dedicated data logger there isn't much alternative.
When the source device (the PCM) is only spitting out 10 frames per second it doesn't matter how fast your data logger is, you'll only get 10 frames per second.

EFILiveV5 uses GM's fast proprietary data transfer format but is limited to GM vehicles.
Autotap uses a data format that is available on GM, Ford and Chrysler vehicles and therefor works on all of those types of vehicles.

What that really means is that by purchasing Autotap you get the best of both worlds.

Re: EFIliveV5 vs ATap I have been toying with the pre-releases of EFILive for a month or so through my AutoTap hardware and can say that EFILive is a much nicer programm to work with. In addition to the higher sampling rates, the user interface is much easier and productive to work with. The export CSV files are also much easier to deal with.
Re: EFIliveV5 vs ATap EFILive Rocks. Like mentioned above, it is easy to use and very professional in nature. I feel like the "mythical" tuner which is above the horsepower law when I use it. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Auto Tap is great too because it does all GM vehicles. I help out a lot of the V6 F-Body crowd around here. They don't have LS series engines.
I plan on using both and will use both. Both are great products that compliment each other and have their nitche to fill in the car world.
BTW, Version 2.0 Auto Tap also exports to csv files.

Re: EFIliveV5 vs ATap When you make these temporary changes on the fly will they hold while you do a run down the track?
Question:
1. I have my laptop mounted in the car at the track to take readings. So with this software will I be able to change settings and then run with the changes while at the track?
2. I bought AutoTap about 3 years ago will I need to buy new hardware to use the new features of EFI Live? (That is making temp. changes to tuning)
3. The $120 version is what is needed to make temp changes to tuning?
