It maps into processor space from 0xd000 to 0xdfff. The ROM appears in the processor space from 0xe000 to 0xffff. Data space in the PROM is from 0x000 to 0x616. Code starts at 0x617 and continues to the end of the PROM, 0xfff. So to learn this where do i go ? I have collected a few proms that I'd like to read so can you good folk tell me what I need Is a prom reader an emulator and burner?cause i'd like to buy one whatever so i can start to work thiis out Cheers Geoff ------------------------------ Date: Mon, 31 May 1999 14:07:52 +0200 From: wenning.motorsport@xxx.de (Alexander Wenning) Subject: Re: RE: g meter Scott Feaver schrieb: > Are you able to scan in that article?

Once a prom is read (see the ftp site index for a bunch of bins), you can use promedit and a corresponding .ecu file to 'look' at the tables (see incoming for SPK747.ECU and promedit.zip, i think). You'll mostly be changing tables to tune a prom, so to speak.

The frame is currently at a body shop waiting to be powder coated - this is the point where Mike ran out of cash, so it sits, and the engine sits in my garage. Plus, he owes me a grand for the advanced adaptors that I ordered to do the job right. Advanced Adaptors has a catalog for jeeps of all years... and we used their motor mounts, bellhousing mount, transaxle mount etc, to make this a simple swap. Chevy 305 mated to a 700R to a ford transfer case with all the adaptors worked out that the jeep driveshaft is "just right" in the back, and the front driveshaft looks like it will be okay, we haven't fitted that piece yet. Before sending the frame out, we did a test fit and everything fit okay (minus the front driveshaft - we didn't get a chance to do that yet). So, when everything comes back after Mike coughs up the cash, it should be a mere bolt together. The motor fit without being offset to either side. With the body mounted, its a tight fit in back of the engine, but nothing I'd be worried about. Just getting at things in the back will be tough. Maybe 1.5" of space as a wild guess. We will be mounting an aluminum plate on the firewall, as well as inside the tranny arch for insulation purposes, just to make sure the heat doesn't bake the new paint off the inside. I have pictures of the disassembly process, though nothing for the test fitting of the engine process, since we'll be going through that again once Mike gets his act together. http://www.xephic.dynip.com/jeep/jeep.html ------------------------------ Date: Mon, 31 May 1999 13:28:50 -0400 From: Frederic Breitwieser Subject: Re: laptop HP measurement (Was g meter) > http://www.geocities.com/MotorCity/Downs/5837/StreetDyno.html It operates Charles posted what I would consider one of the best (and free) solutions.

That is one cool Z. I think I remember seeing it. Red with Newer Taurus headlights? Anyways, I think it might be easier to run a toyora Supra rear diff. I know they are available with 3.90:1 gears and LSD. I don't know if it will hold up to 10 sec. 1/4 mile times. I thought indi-rears were not allowed into the 10's by both NHRA/IHRA rules. One other thing is that the Viper has 6 lug wheels and I don't know what the plan would be for rims.

How much ya think, just for the block alone? According to my MP books the 440 block with caps weighs 225 lbs. Don't remember the figure for 383/400 but it's probably not a whole lot less... If you want a surprise weigh a 440 steel crank sometime ;) - -Charles ------------------------------ Date: Mon, 31 May 1999 14:42:54 -0400 From: "Gary Derian" Subject: Re: Prowler V6 The ZZ3 and ZZ4 have cast cranks. The ZZZ, ZZ1 and ZZ2 are forged. I have a new ZZZ if anyone is interested. 1969 was the first year for 4 bolt Chevy SB. Z-28 and LT-1 only. L82 later also. I have never heard of a 10,000 rpm stock Chevy. Lots of trucks got cast cranks with 4 bolt. Cast iron is a very good material to build a cheap crank with. Cranks are stiffness limited, not strength limited at low rpm. The high winding motors need forged cranks. 4 bolt blocks are very good for improved bearing alignment for high engine loads even at low to moderate rpm. Just like trucks do.

I temporally gave up on Ford OBD2 seems to use initialization bits defined by the Ford Standard Corporate Protocol documents ES-F7LC-12K529-BA and ....CA Have not visited by local Ford dealer lately for jokes VPW is similiar to rs485 rs422 from what i recall the recv. work great but transmitters don't rather sensitve to impeadance matching. http://www2.ari.net/avt-inc/download.htm has some references, also rather helpful to me when I first started in OBD2 if you have interest in there development systems have not talked to them since 96 http://www.okisemi.com/communicator/public/nf/docs/Intro-7017.html has a interface chip, schematics and general J1850 info. some of there pdf can end up as txt on your web page. i think you also need a one time registration. Presently I have a rs232 to PWM PIC byte translator. Have no Ford, sometimes borrow a 96 snap-on to play with. alex ------------------------------ Date: Mon, 31 May 1999 19:01:49 +0000 From: xxalexx@xxx.com Subject: Re: g meter > > Circuit Cellar Inc. #107 june 99 has good article on the > > ADXL202 +-2 g accellerometer with 0.001 g resolution > > Even sensitive to going up and down hills (0.016 g per degree) > > Complete boards avaliable under $30 from Jameco > > and Crossbow. > > alex > > Alex -- I've been around the jameco site and can't find the boards you > mention.

Note these are made by a Crossbow. documents at ftp://ftp.jameco.com Also a optional interface card for $259.95 #141583 The CCI article said they shot a entry level Crossbow 202EB for $29 on a 5 pin header 0.1" DIP with choice of resistors and caps. Also a 6 degree fiber optic gyro available if you loose your arrows. http://www.xbow.com Microsoft is using the ADXL202 in the Freestyle Pro game controller which senses body motion. I'm sure uses Dierect-X code so you could convert to HP meter and play body games too.

I need to put together a fairly comprehensive list of the wiring for EGO/HEGO sensors. For example, wire color codes and what each is for in a list of types and car/model years.
