However, say in 1988, you could have the ARX/0386 or the ARX/2628 with your 2.8L. I have ways of identifying proms with the letters only, but the best way by far is BCC(letters)+external id(numbers).

Good picture, looked like it had cruise, A/C, all the bells & whistles you could want on your Big Chief Steamer. If anybody has a copy of that book, I would REALLY like a copy of that picture.

It runs fine on my win95 machine.... I got the EMP-10 programmer, Diacom, and promedit all on the same laptop and as soon as I get an rs232 cable I will have the 32 bit emulator as well, This will keep me from running back in the house every time to burn a chip, all I need it to get promedit working... any suggestions? thanks Jason - -- Jason Weir 88 Wrangler - 258 Chevy TBI Fayetteville, North Carolina http://home.att.net/~jweir/tbi/inject.htm --- TBI Installation Page mailto:jweir@xxx.net ------------------------------ From: "Bruce Plecan" Date: Sat, 3 Oct 1998 13:10:11 -0400 Subject: Reading a Holden's mind When using a Diacom on a 808, is there any specs about what ya can use instead of a bulb for reading the serial data? I tried using a 10K resistor, and things seem fine, just curious if there is a recommended value.

Now that I have my EMP-10 running off of my laptop I am not sure how much I will use the emulator but for $50 its a fun toy to have.... later Jason - -- Jason Weir 88 Wrangler - 258 Chevy TBI Fayetteville, North Carolina http://home.att.net/~jweir/tbi/inject.htm --- TBI Installation Page mailto:jweir@xxx.net ------------------------------ From: Ed Date: Sat, 03 Oct 1998 21:20:36 -0400 Subject: Not really EFI-related, breaking in an engine on a chassis dyno I remember reading about an engine break-in procedure on a chassis dyno.
