Best Ls1 Tuning Software
Step By Step
Putting a 5.3 in 86 stang using a street and performance harness, and a ls1 computer, car will be n/a first, then turbo next year, what tuning software do I buy? Sep 20, 2010 PCM Diagnostics & Tuning - READ ME!!!! *****Best LS1 Tuning Software? Best Scanner? Best Handheld?**** - If you post up asking which is best, Help me Pick, HP tuners vs LS1 Edit, EFI Live vs HP Tuners etc. Your thread will be locked.:lock: For those that insist I tried to search and didn't find anything.
Here is what you'll get from Carputing: The interface module, ALDL cable, USB cable, software CD, and an installation sheet. The laptop connection is USB type, which results in faster PCM reading and programming times.
Technically, any computer that meets the minimum requirements can be used, as long as you can get it to the car. Hauling your desktop into the garage may not be practical, so consider picking up a laptop (new or used will do). Tablet-type laptops are the best for programming. A trip to eBay netted us a suitable used tablet for under $300.

The first step in programming is to shut off all screen saver and power management functions. With the mouse in a clear spot on the desktop, 'right click' the mouse and select 'properties.' You'll find everything you need under the screen saver tab. Once you're done programming, you can reset to your normal screen saver and power management settings.
The new keyless ignition system on C6 Corvettes will make the connection process somewhat of a challenge. The ignition must be 'on' with the engine 'not running' to enable reading and programming. We moved the shifter to neutral and cycled the switch until the display called for pressing the brake to start the engine. Ten seconds after reaching this mode, we were able to initiate the program. The LS2 employs a split PCM setup, including an independent ECM (engine control module) and a TCM (transmission control module). You'll need to read and tune separate files for each.
TCM file editing is split into two main sections. The Transmission Calibration section encompasses the majority of trans functions. The Transmission Diagnostic section, not active in our early version of LS2-edit, will eventually house the tranny-related DTC codes and self-testing toggles.
Flash tuners are all the rage now. After the evaporation of ECM 'chips' from the OEs' offerings around 1993, it took a solid 10 years or so for the PCM re-flashing business to evolve into the reliable and fairly optioned market it is today. Carputing partners, Ken Kelly and Dave Hempstead, have been two of the pioneering forces that have consistently led the pack along the way. We found it most appropriate for the next step in our continuing GMHTP flash tuner series to test Carputing's latest offering, LS2-edit. Carputing got its start back in 1999, when principals Ken and Dave met each other through a chance virtual dialog jawing about LT1 transplants on an Internet message board. Ken, a 28-year veteran of cellular research at Bell Labs, was dropping an LT1 powertrain into a 1948 Ford roadster and Dave was installing an LT1 in his 1934 Ford roadster. The duo, armed with a combined 56 years of professional electronics and computer experience, quickly realized they could 'build a better mousetrap.' The mystique of flash-memory type PCMs was still cloudy at the time. Enter LT1-edit. It didn't take long for the word to spread about LT1-edit and with that came the demands for a similar LS1-based tuner package. Carputing responded with the first flash tuner available to the masses for reprogramming the LS1 PCM. Since then, Ken and Dave have consistently been the first to market with subsequent packages covering all Gen III/Gen IV powertrain offerings, from 1997 through 2006.
LS2-edit, or 'Edit for short, is based on the same familiar LS1-edit architecture. Emphasis is on function and capabilities, rather than fancy colors and loads of graphics. Several notable improvements have arrived with LS2-edit. The flasher-to-computer interface is now super-fast USB-based, rather than the old and slower serial connection. Karte ho tum kanhaiya song mp3 download. The flashing process has evolved into a seriously robust and safe process, practically eliminating the infuriating side effect of any mishaps during the flash process that, historically, could result in frying your PCM into a doorstop; Ken tells us no ECMs have been 'fried' with LS2-edit. Yes, ECM, not PCM. The LS2 arrived with a split powertrain controller running on a new CAN interface; an engine control module (ECM) and a separate transmission control module (TCM) communicating across the General's new controller area network (CAN). The good news is that LS2-edit covers both. The ECM and TCM parameters are both 'Edit-able. The entrance of the CAN interface was a huge obstacle to overcome when introducing LS2-edit. Rather than simply deciphering the '05 codes for the LS2, Carputing had to develop a new module and computer interface capable of working with GM's tricky new CAN setup.
'Edit continues to be a work in process. Included with each purchase of 'Edit is a 6-month update service agreement. Every time an update or revision to 'Edit becomes available Carputing emails a set of new files to active recipients. Beyond the included six-month agreement, subscriptions are offered for $50 per year. The update system allows consumers to get their hands on 'Edit as soon as possible--and get the basics of the tuning handled up front. As the program evolves, additional work can be made to the tunes. The system also allows feedback to help drive development. Asusers push for features, Ken works to add them to the next revision.
Getting started with 'Edit is straightforward. A visit to www.Carputing.com and a credit card with $550 will get you started. A few days after ordering 'Edit, we received a complete package including the flash module, all necessary cables, a CD with the program, and a few instruction sheets. Within a half-hour, we were hooked up to the ALDL connector on our test 2005 C6 and downloading the base tune. For those who are lighting up their first 'Edit experience, helping advisors are available. Carputing offers an optional group email exchange forum subscription to buyers. Any questions can be emailed to the 'forum subscribers,' basically consisting of all prior 'Edit buyers/users. Typically, within minutes of blasting out an email, someone will respond. This is an excellent and powerful experience-sharing mechanism. If that fails to satisfy, most of the major message forums have dedicated 'tuning' sections for communication. Fellow tuners are quick to offer assistance, advice, and often sample tunes. We recommend jumping in (to the tuning pool); the water is fine .. as they say.
LS2-edit is available in two versions--licensed for a single PCM ($550) or licensed for unlimited PCMs ($2,995). If you order the single license version, you can also add a license for additional vehicles for $100 per extra vehicle. For our evaluation of LS2-edit, we secured a willing 2005 Corvette C6, equipped with a bolt-on beefed LS2 and an automatic transmission. Our baseline dyno testing yielded an SAE corrected 383.5 rwhp/378.9 rwft-lbs. Wide-band readings recorded a rich 11.5:1 air/fuel ratio at WOT. Spark advance was logged at a lazy 20 degrees BTDC at WOT. From prior experience, we know the Gen III/Gen IV makes peak power in the vicinity of 27 degrees BTDC and 12.9:1, so our fuel and spark tables needed work. Besides dialing-in the fuel and spark delivery, our transmission tables needed some hot-rodding. The C6's factory shifting schedule is well on the conservative side, leaving plenty of room for improvement. Stock torque converter lockup comes on really early, and downshifting is only programmed for nearly WOT command. Stock upshift points are not bad, but we wanted to squeeze a few more rpm out of each gear to complement a reassigned rev limit. After some experimenting on the dyno, we found the sweet spot to be 27.5 degrees of spark advance at WOT, to ignite fire on our leaner 12.9:1 WOT command. We turned off the catalyst over-temperature enrichment during testing to allow us to dial-in the base fuel ratio. After testing, however, we re-enabled COT service. From our track testing data logs we've found the COT not to be a problem when the vehicle is moving at high speeds off a dyno. We ended up with SAE corrected 393.5 rwhp/386.0 rwft-lbs. In addition to the gains on the dyno, we also fixed a few other issues. We zapped the infamous MIL set from our long tube headers. We bumped the rev limiter up 200 rpm and added 50 rpm to each shift point. We also (bravely) deleted what was listed for torque management.
