I would love to get into burning my own chips.What hardware and software is required and whats the cost?My brother has a 89 daytona turbo, is there any way to do his car too?

 

Check out the technical article on this very topic on the main site.

This isn't really on topic I guess, but has anybod with an extra ECM set one up as a dedicated "chip reader station"? I recall somebody doing a write-up on what wires to connect, but I haven't been able to find it recently. I would guess you'd only need to hook up the power and serial lines, no? I was thinking I'd maybe wire up the SES light, just to indicate that the ECM is alive.

Since I have 3 ECMs and my chip writer is an ISA card in a desktop computer (too bulky to haul out to the car!), I'll use the computer and spare ECM as a "read/write center". My first goal will probably to get the '89 305TPI code to work on my '86..

 

anyone?

 

gravitar,

Do you mean an ECM Bench? An ECM bench is where someone mounts an ECM and its harness to various sources to allow the ECM to run as if it were in a car. You can hook up diacom and view parameters. This is an awesome way to test different bins.

I wasn't actually planning anything that ambitious, at least for now. What I'd like to do is, since my first actual PROM project will most likely be to take a factory '89 305TPI A4 chip and make it work on my '86 setup (remove VATS and maybe a couple other tweaks), I was thinking about setting aside an ECM for doing nothing but powering up the PROM carrier, and allowing me to download the contents of the PROM via Craig's MAX232 board and his software. I could then edit the areas of the code that need it, write it to a new chip using my PB-10 programmer, and pop it back into the ECM to verify that it wrote correctly. I'm thinking that all I'd need to do is hook up power and ALDL lines to the ECM, and I should be good to go.

Is this a good assumption? I shouldn't have to "emulate" any sensors or provide any other signals to the ECM to make it run in that minimal configuration, should I?
