TunerPro RT

• Free! (With nag screen, and registration reccommended)
• Some beginners find configuration difficult (but highly customizable)
• Integrated data tracing and bin editing (hilight active cells in tuning tables)
• Can potentially read/log/display ANY datastream element (depends on ADX)
• Multiple graphing (requires manual configuration)
• Customizable dashboard (requires manual configuration)
• Running average history table analysis (no record filtering capability)
• Can tweak ANY engine parameter available in the mode 4 message (like eehack), but only to fixed pre-defined values in ADX, and new commands clear all previous ones. Requires datasheets and manual configuration, so difficult to use for many practical purposes.
• Wideband input no problem (requires raw configuration, knowledge of datastream, and some math)
• .. It also edits bins!

EEHack

• Free!  (And open source) (beer money appreciated)
• Highly portable, Windows version is well supported and tested but can run on Linux or MacOS with some work.  Source code available.
• Displays and logs a huge variety of parameters, including some that can be patched in, such as Target AFR.  No ABS/SIR codes at this time.  “Fast” mode with increased acq rate available.
• ‘Dashboard’ display for common parameters plus four user-defined parameters, as well as tabs with all data listed in table format, with optional ‘view level’ filters.
• Real-time testing.  Temporarily skew timing advance in real-time for ‘by feel’ tuning or research, either manually or automatically with 3×3 map/rpm “AutoSpark” table. Temporarily set forced AFR target, arbitrary idle target or iac steps, closed loop, BLM learn, fans, auto trans geras, TCC, etc. in real time
• Disable arbitrary injectors per-cylinder manually, or run an automated test that estimates cylinder balance.
• Wideband O2 input two-point arbitrary configuration, presets, and optional smoothing, both using AC pressure and another unused pin.
• Onboard notepad with limited parameter snapshotting
• Full-time data recorder with optional log stacking. If you’re connected, you’re logging, all the time.
• Proprietary log format for storing logs (stores extended data)  or CSV data output format.
• Custom ‘raw’ command insertion with automatic checksum and length calculation, single-shot or loop mode
• Two large synchronized anti-aliased graphs.  Can highlight graph areas with binary values such as closed loop enabled, wide open throttle, fan on, etc.
• Very fast static parametric ‘one-click’ fuel and knock analyzer suite:
  • Global coolant or timestamp restrictions
  • Cellular BLM/INT trims or wideband REAL average in both VE MAP/RPM and MAF AFGS scope
  • Power enrichment analysis in rpm vs map
  • o2 performance analyzer
  • Seperate idle trim bank display
  • BLM population and range analysis
• Reads and sets arbitrary VIN to any 17 digit string and CAL ID
• Flash READ with or without RAM section
• Flash WRITE with optional T/E side selection, bin compare feature with auto-save, 0xFF compression, aggressive failure recovery, and passive datalog-enhancing patch insertion
• … More.

TTS Datamaster

• Is now discontinued and unsupported
• Retails for approx $120
• Logs all useful engine data
• Logs all useful transmission data
• Custom RAW parameter definition, for widebands etc
• Simple ‘running average’ BLM histogram analyzer
• Clears DTC codes
• Retrieves VIN number
• Saves CSV logs (configurable)
• Simple 4 channel data graph (Small)

WinALDL

• Classic program works well on very old PCs, but no longer supported and has trouble on newer versions of windows…

What’s in store for the next release??

First off, since it’s now a flash tool, the next version will start transparently patching your bins as they’re programming for more/faster/better data to play with.  Since we’re the flash tool and the logger, we can slip in some code into the unused aldl modes and messages.  There is a bunch of unused aldl code that can be abused for more data.

These patches will be silent and safe, and have a persistently stored version byte (which can be fetched immediately on connection) so EEHack will tell you if your ECM version and EEHack version are out of sync, and enable enhanced features only with the correct patches installed.

First patch is an easy one, I have constructed a shorter message for speed logging which doubles the sample rate (if you don’t mind giving up error codes, a/c temperature, or anything else useless for actual tuning…)

A kind LT1 enthusiast is donating a wideband to me, which is a BIG deal since now I’m inspired a bit…

Tweaking the datastream opens up some possibilities, as does kur4o’s recent patch to enable memory dumps on the e-side just like the t-side already has.  With open loop AFR target in the datastream and higher sampler rate and direct access to the bin, this means the analyzer can compare open loop AFR target with actual wideband AFR at an increased resolution, giving you an accurately corrected VE table with no messing around or reflashing while you’re building it.  The existing tables themselves, if required, can be dumped from the bin without reading the whole thing…

Hell you can even force open loop without flashing, so the idea is, if you have a wideband and you feel your AFR is drifting out of whack, just click connect, force open loop, take a drive, and hit ‘analyze’ when you get home.

What about the flash tool?

Other than more stress testing and stabilization… It’s getting way faster data rates too, abusing the fact that EEProms erase to 0xFF (11111111) to decrease the serial bottleneck.  This means that 0xFF bytes don’t need to be transmitted for them to be programmed, they’re already in the correct state we just have to play with chunk sizes a bit to reduce write traffic in certain areas.

We can also blank out unused/unreachable sections of the bin, for example, automatic transmission tables in manual bins don’t matter, and MAF tables in VE only bins don’t matter either.  This is also transparent, and doesn’t involve modifying your bin as it’s stored on disk.  Could save thousands of bytes, and with our already existing single-sided write, we could be sitting around waiting for flashes a lot less…..

Stay tuned.
