Hey guys. I am sure these questions have been asked 1000's of times on this forum but nevertheless I would appreciate the help.

<img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Well I really need to change my top speed on my 03 5.4L Sierra so LS1edit or the Diablo Predator are two of my best options. Right now I dont have that many mods. Engine mods are only the Corsa exhaust. Eventually I plan to get a supercharger, whipple, ati, or magnacharger. The truck is my daily driver and street car. I plan to race it on the drag strip every once and a while. I also have access to a dyno so tuning there isnt Now I want to see what everyone has to say about the two.

1.) LS1Edit

First and foremost: How hard is it to program?

I am pretty experienced with computers, engine/car tuning. I have an Accel DFI (digital fuel injection) system/stand alone ECU on my turbo honda so I have some tuning knowledge. I have never tuned it with a laptop but I have seen it done, along with a wide range 02 sensor and knock meter.

It sounds like Ls1edit has better custom tuning capabilities.

Does it use a portable plug in controller like the HPPIII?

Can it interface with a laptop?

What type of control do I have over the engine?

Any links on it? Pics? How much is LS1edit?

Can it do anything the Diablo cant?

2.) The Diablo looks cool with its features, especially the code grabbing.

Can it do things LS1 cant? Its about $420 so it looks like for $80 more I could have Ls1edit.

Well I hope you guys can help me out. Does anyone know if Tbyrne motorsports sells LS1edit?

I would really appreciate the info. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

thanks, <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I'd buy Edit. It is very robust (although I have not tried the diablo) and pretty easy to use so long as you understand what you are doing if you get into the fuel maps etc.

Edit requires a laptop, preferably with a serial port. It just plugs in like a HPIII and downloads in the same time or faster.

 

Predator will say their unit is also a scanner. It does not have logging however. It is not really possible to tune the mods you plan without logging. Edit has greater tuning capabilities and you do it all without having the Predator supplier interpert your needs and setting up adjustments. I have no trouble using Edit. Which means anyone with the desire can too. With your understanding and with any curiosity you should use Edit.

 

So how much is ls1 edit? It includes the cable and software correct?
What kind of software?

It doesnt allow adjustment of the fuel map does it?

What can it adjust? Ignition timing, shift points, redline, etc.?

Also what are the computer requirements to run the software?

I have a few laptops but they are pretty old?

They both run Win 95 but I could easily upgrade to Win 98. They also have very little RAM (16/32 MB RAM) but obviously I could easily upgrade to more RAM

thanks for the info. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

 

LS1Edit is $550 for the license and cable.
The Predator is for $425 for the handheld unit and cable.

Edit requires a laptop.
The Predator doesn't.

Edit has no scanning capability whatsoever. You would need ATAP.
Predator has real time diagnostics scanning. Although not as intensive as ATAP and without the logging capability.

Edit can adjust as far as you want in all sorts of parameters including A/F and timing.
Predator can adjust up to 1.5 points of A/F rich or lean and can adjust timing up to 2 degrees advance or retard.

Edit comes with 1 free update which has to be sent to you.
Predator is net upgradeable and will have free updates for years to come.

Edit has more adjustable parameters out of the box than the Predator for sure. But you really need to head to www.carputing.com and download the user guide. There are a lot of parameters you will probably never use. But check it out and see for yourself. The upside to the Predator is that when you do install the blower, you can just get the custom tuning. Most people who do major mods will really only need 1 custom tune during the life of the vehicle because you can still make modifications to it at your discretion. Another plus with the Predator is that even if the dealer reflash's your ECM, you can still use it because it's linked to the VIN. Edit doesn't have this advantage. Edit is a good software package but the Predator is right up there with it. While Edit has the advantage of a broader range of adjustable parameters, the Predator is a self contained unit and has real time diagnostics built it.

If you have any other questions or if you want a good price on the Predator, send me an E-mail. I didn't check to see where you are, but I can also set you or anyone up with a good dyno package using the Predator and a wideband 02. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

BullSSeye.

I am about to purchase a 98 f-bird
what would it take to be able use a
predator on my car?
they say it is n/a for my year why?

thanks
spankt.

 

I will have to make a decision on which to get very soon. Diablo seems easier to use, but you can't yet adjust the idle with it. I need that for my cam change. Any idea when you they will update it for idle adjustment? If it's not in the next month or so then I'll have to get edit.

 

spanktu: You would probably need to E-mail DS directly at general@diablosport.com or page BfB to answer that more accurately. But I believe it has to do with the release level of OBDII. It's also not applicable on 97 and 98 Vettes even though both years had the LS1. So I think it's a compatibility issue. In which case Edit would be your best option. But if you're interested, I can still see about a good dyno rate and some skillled assistance tuning with your LS1Edit software and laptop if you're in the Northern Ca. area. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> (Sorry, just realized you're in Va., my bad <img border="0" title="" alt="[Embarrassed]" src="gr_emb.gif" /> ).

PewterEllis 1: It would be a safe bet that idle adjustments in the unit itself are going to be more than a month out. I believe you can get it done now, but it would be through custom tuning. Which is a good idea anyway with a cam. The dyno shop where we did our Predator beta testing is supposed to be getting the custom tuning software very soon. But I don't want to tell you that it will be two or three weeks and have it end up taking 2 months. I'll make a post as soon as it becomes available. Again, you may want to go through DS's custom tuning now regardless of idle settings. Of course, that depends on your cam specs and how radical they are. But I'm sure you're at least 220 @ .050 if you went to the trouble of swapping the cam. Think about it this way: The Predator is $425 + about $120 for custom tuning through DS. That's $545 for everything including the custom tune. Or, you could get just an Edit license and cable for $550 but without any custom tuning whatsoever. Which still makes the Predator a better deal. And I can get you a very good dyno package if you're in the area. Or a good price on the Predator itself if you're outside of Northern Ca. LS1Edit is a good option for you especially considering your time constraints. But the Predator is still viable to be sure. You would just need to call DS and see if they can custom tune for your specs before they even send it to you. Or, you can get it from my friend now and send it to DS. So there are still a few options for you. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
