Flashing the LM

[cordes]

If I were to modify my LM in my omni per the moparchem.com site, would I still need the burner, or could I just use a laptop to flash it in the car?

Any advise would be appreciated here, as I am looking to get started on making my omni run with my own cals, and I want the simplest way to do it.

I don't believe you can make a LM flashable, only heard of the SMEC being made flashable.. BUT.. Since the LM uses 8k images, you can get away with using a 28C64, which I've been told is DIRECTLY pin compatible with the stock 27C64/27C128 etc etc chips.The 28 series is flash memory, so you don't have to use a UV light to erase it,but you do have to pull the chip out of the LM and put it into a burner.. Saves some time..

The LM is flashable. Geoff corrected me on that one a while back. I'm pretty sure he has the instructions to do the mod on the MoparChem.com website...

After you mod it to be flashable, you won't need a chip burner. You can send the new cal to the LM from a laptop...

someone got the LM to be flashable via chem. I tried it a couple years ago and couldn't make it work on my 87 LM. If you get it to work let us know. I'd like to leave my GLH stock electronics wise.

Here is a little bit about the conversion.

hehehe, socket the unit, use a burner. Pretty simple that way.

I have wondered if there would be a problem with making a remote socket. Something to tuck into the glove compartment to hold the prom. I'm thinking there might be data latency problems. Any electrical engineers wanna chime in?

The ROMulator uses a cable.. So it's like a remote eprom.. But it may have additional circuitry to combat any problems the extra wire length adds..
