Lets talk PCM tuning and LS1-EDIT I know we have some potential sponsors logging in as members now, these are the guys with their hands on LS1-EDIT right now. I want some impressions of the software, and I want to know the full capabilities of this setup.
When are the single-use versions going to be available, and how much of a learning curve is this software going to require for an "average" tech guy versed in Autotap and tweaking MAF-Ts?
Anyone with technical knowledge on PCM tuning, jump in!

Re: Lets talk PCM tuning and LS1-EDIT we're going to get the shop edition before too long. Its already out for 99-00 cars I was told by carputing.
They just need to finish user documentation for the single licenses (so they say <img src="images/icons/rolleyes.gif" border="0"> )

Re: Lets talk PCM tuning and LS1-EDIT First some background info on me:
I'm a former user of LT1 Edit with my '94 Trans Am and a member of the lt1edit, gmecm, and diy_efi mailing lists. I've done a little reverse engineering on the 93 LT1 chip and tweaking for my '66.
I think the most important thing is to have a group of people that can learn from each other. The LT1 editor mailing list is awesome, not only do the lt1 edit authors post, but even respected tuners such as Mike Licht and Ed Wright. I'm sure there will be a similar list for ls1 edit and once the single user version starts shipping I'm sure we can generate enough traffic for another section on this board.
Ken (the author of the editor) is very responsive to suggestions, and if there is anything missing from the editor he'll add it.
Just last week Ken told me the price for LS1 Edit single user will be $550, while this is more than the original OBDI version of lt1 edit, its the sam e price as the OBDII lt1 editor and is well worth the money. It should be out by the end of the year.
To answer your original question:
Being versed in Autotap is a good first step, but tuning the tables in the pcm isnt going to be like turning the dials of a MAFT, but its rewards can be greater. WOT tuning has always been pretty easy in the pcm, part throttle is a little trickier. To help with this a clever lt1 editor user wrote a tool called VEmaster, which interprets the logs of a scantool and adjusts the volumetric efficiency tables in the pcm accordingly. Given time I'm sure a similar tool will be written for ls1 edit.
Its an exciting time to be into LS1's <img src="images/icons/smile.gif" border="0">

Re: Lets talk PCM tuning and LS1-EDIT I dunno, I FINALLY got my PCM sorted out thanks to Steve Cole and she's running stronger than ever, I'm not so sure you want to turn me loose with a program like LS1 edit on my PCM. <img src="images/icons/grin.gif" border="0">

Re: Lets talk PCM tuning and LS1-EDIT can the shop version do everything that a custom program can do? what are the pros/cons of the two, im looking to bump my idle speed, raise rev limiter, adjust fuel/air ratio, whatever else can be done to maximize performance....can this be done with ls1 edit like ed's tuning?

Re: Lets talk PCM tuning and LS1-EDIT This is a good thread!! To add to some of the options, Steve Cole at TTS is coming out with a simulair system as I understand it...Faster than ATAP`s four frames per second and will have tuning capabilities..I spoke with him at the SEMA show about it... We still need more details though..
Tony, I heard a friend of yours has this ls1 edit program already or was I misinformed?

Yes, I also heard from a reliable source that TTS will be making DataMaster for OBDII and possibly an editor. Apparently DataMaster is in progress, but no work has been done toward any tuning software. I dont know how much I'm supposed to say...

I understand the EASE Scanner is the way to go over autotap. And that they make the GM Tech II?
Can anyone confirm?

It is only available in a TUNER version. The $550 single user version will be available in a month or so.

Re: Lets talk PCM tuning and LS1-EDIT I just hope I'll be able to use it in addition to the custom tuning I have now from Mr. Wright. <img src="images/icons/rolleyes.gif" border="0">

Re: Lets talk PCM tuning and LS1-EDIT Yea So how would we hook up a 99 comp to a 98? If it could be done cheaply I would do it then get ls1-edit. Is there a thing for picking injector sizes or do you have to just lean it out on your own?

Re: Lets talk PCM tuning and LS1-EDIT Now you have my attention. <img src="images/icons/grin.gif" border="0"> What do you mean by the VE tables in the PCM? Can you explain a little more detail on those?
Thanks

Re: Lets talk PCM tuning and LS1-EDIT Hey guys! Great Topic!
I've been tuning LT1 PCM's in house for about 6 years now and have learned nearly everything there is to know about these computers. I recently acquired LS1 Edit for the '99 - '00 cars and let me tell you, there are some similarities but the LS1 PCM is extremely complex compared to the LT1. It is really a great program for people who wish to spend the necessary time learning about and tuning their cars. You will not be able to just "jump in" and start making adjustments to your PCM. The spark tables, knock retard and A/F ratio tables require a lot of time and patience to begin figuring out. Once you do though, fine tuning a car will be fairly easy. It's also nice to be able to select and turn off various codes to prevent any annoying check engine lights.
I've done several PCM's for cars in house now with various combinations and have seen some great results! I'll keep you guys better informed as I begin to master the program! <img src="images/icons/smile.gif" border="0">

My guess you would have to have the wire harness getup from a 99 car also. I am not sure how much they would be but I can imagine they would run about $800.
Can someone confirm this? The 98's and 99's have different pin assignments for tach operation and such. I am not sure how that might cahnge the outlook on such a project.

Re: Lets talk PCM tuning and LS1-EDIT I agree we should have a forum or whatnot dedicated solely to LS1 edit once commercially available. It'd be nice to share experiences amongst ourselves.
We should have our Tuner version in a month or so...I plan on learning this program and hopefully spending some quality track time testing it out <img src="images/icons/smile.gif" border="0">

Re: Lets talk PCM tuning and LS1-EDIT Wow, a post by "The Man" himself...welcome to the forum Jayson. I need to have you do me a program for my '98 SS...the tuning is just not "Wright".
