4-cylinder Delco ECM that uses flash instead if EEPROM?

I just can't stomach giving HPtuners money after how he did the tuning commuity that helped him get started, or I'd look into a few of the OBDII units to see if they are easy enough to convert.

I also remain disappointed at what happened. And I am frustrated that TC sold their software to JET. It's too bad that we don't have a reasonable solution from the DIY community 21 years after OBDII hit the market.

im trying to do something else with the 93 cav ecm. i need to change the settings on it but i have no software to read the ecm or know of a way to flash it back to it. i do have a aldl cable.

I haven't messed with this in a long time. Still exploring the P66 code, kinda forked the GM code and have been hacking in some "universal IO" stuff, things like allowing the EGR outputs to be programmable on two logic conditions. Basically I've got three outputs that can be toggled on/off based on one or two conditions, but so far you can only setup 1 at a time or the code crashes.

[metallica21156]

what software are you using to read the ecm?

I'm not-I just sniffed it out with a scan tool and bus pirate.

I'm looking at this.
