New release of EEHack is ready.

Among other things, I think we can consider this the first release of my FREE LT1 flash tool!

I’ve put a lot of time into this flashing routine, and although I’d not officially recommend it to poor LT1 users that only have one car or one ECM yet (just in case a bug pops up) I think it’s ready for public use. Also, try reading a bin first, before writing your first bin!

About the Flash Routine

This flash tool has a ‘take any long shot to save your ecm’ philosophy to error recovery, which, on any unrecoverable error, tries its best to regain control, erase the chip again, and start over. It also tries to verify your serial connections integrity before even trying to do anything.

It also features single-sided flash, which will flash the e-side or t-side only if desired. It can also conveniently compare your old bin to your new one, to determine which parts need to be flashed. This potentially cuts flash time and risk in half if you’ve only made a small change or two!

This is a big deal to people tuning on a budget, as with a free copy of TunerPRO (Non-RT) and my EEX XDF file, you can have the most advanced tuning and analysis platform for your 94-95 LT1 for only the cost of an ALDL cable (I’m working on making that cheaper too….)

Not 100% sure on this, but perhaps now the 94-95 LT1 is the cheapest GM car to tune EVER!

Wideband Enhancements

This new EEHack release is also important to people with widebands. It has an additional analyzer feature to plot wideband readings in cruising range, a commonly requested feature.

Also has a brand new wideband input on a dedicated pin so you don’t have to use the a/c input hack anymore!

Your website/work is 10/10 This is awesome! Ill be playing with this stuff soon.

 

so far half a dozen users and nobody has bricked an ecm with it... it's lookin' pretty safe....

 

Nice, going to need to check this out.

 

Too bad there is 7 inches of snow out here right now.

 

Sucks, been really wanting to try this as well but just got my trans back and life is in the way for now. Hopefully spring time

 

Awesome! - Thanks again Steve. Sadly, my car is also in storage complete with mothballs and mouse traps ... I will have to wait until spring to try out the new features. Looking forward to trying the wide band interface, too. Really cool!

 

not a bad idea to wait anyway!

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 possibilites, 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.

You really put a lot of effort and time into this project Steve.
Greatly appreciated.
I have always done OBDII stuff, but am about to start digging into the OBDI with a new project.
AKM cables is down, can you point me in the right direction where to get a cable?
Thanks

 

i make my own using ebay parts and hardwire a usb cable into my car these days, but have also bought one from http://aldlcables.com/ with some success before.

 

i installed the program and i keep getting an error message that the program cant start because Qt5Widgets.dll is missing. try reinstalling to fix this problem. Did that and still same issue

 

Didi you do the following?

 

i should re-organize my download page to make that clearer.

edit: hope this works better http://fbodytech.com/eehack-2/download-eehack/

 

Thanks is missed the step of placing in the same folder as eehack. Thanks..Now i have to wait for my ftdi cable

 

while waiting for your cable, look at the very bottom of the eehack download page, i've put a 'test log' there. you can load it and play around to help you get used to the software's analyzing and graphing features.

 

The test log doesnt seem to work. I downloaded it and go to open it and nothing. I locate the file and open it from the directory and it says there isnt anything there.. Does it need to be opened with something else... i running windows 7 fyi

 

i have no idea what kind of crack you're smoking. if you can't even manage to load a log file into eehack, it might be a bit advanced for you.

windows error: there isnt anything there

really?

 

You need to extract the log file from the zip archive before you can open it with eehack.
I imagine if you were to browse to the folder with eehack to open the log file and all that's there is a zip file, then eehack will just show an empty directory.
