Simon Quested wrote: > A$25 for a starter kit... > Is this the sort of thing that is good for a complete beginner in PICs? > (like me) I think that it's very good value, BUT, you have to ask yourself why you're going to use a PIC. These devices are great for performing many small logic functions - and the Scenix devices (fast PIC clones) seem to be fast enough to even replace existing hardware devices (perhaps even a slow CPU). The biggest drawback is that the PIC has only small amounts of program memory. This is built into the architecture and means that larger projects are much harder to program because you have to worry about things like your code crossing a page boundary, etc. Traditional microprocessor architectures like the 68HC11, 68332, etc. can access lots of program memory and are not limited in the same way a PIC is. On the other hand, to do anything with one of these "bigger" chips, you have to write a lot of code just to get the CPU to power up its internal circuitry and talk to the outside world. You may have heard about the Basic Stamp (and like clones) that can be programmed in BASIC (or even C). These devices use a PIC chip, but they read an external program (usually stored in a serial EEPROM). For each high level instruction it interprets, the PIC has to read the EEPROM, decode what is required, then do it. This slows the PIC down by orders of magnitude compared to running from its "native" mode, and compared to an a "traditional" microprocessor. In general a Basic Stamp (or similar) is NOT suitable for an EFI project. On the other hand, a simple ignition controller is quite do-able (Jaycar also have a PIC ignition controller kit!). I have to be honest and say that if you want to get into programming micros then one of the best things to do is get something like an Apple II or C64, etc. People are throwing them out and you can get them for nothing (perhaps someone will pay you to take one away!). Get a book about programming, spend some time getting to know how to program your CPU, and then, if you're still motivated, AND you really have something you want to program, team up with one of the current EFI332 projects and you'll be in a position to understand what's happening. If you do get say an Apple, what you'll learn may not be about the same micro that's in a particular ECU (although the 6502 is not unlike the 6800 which is the basis for the 68HC11 which is used in many GM ECUs) but it will give you a basis for understanding how the microprocessor in the ECU works - that has to be good for something! regards, - -- Peter Gargano ------------------------------ Date: Tue, 01 Jun 1999 15:46:12 -0700 From: "Todd....!!"

POSI (Positraction) is nothing but Chevrolet's brand name for limited-slip...I constantly encounter people (metric hammer users) who insist that "Posi" is a technical term for any non-open diff, while "limited slip" means an open diff..."limited" meaning it slips until you let off the throttle.

Offshore boats as they jump from wave to wave has not full contact with the propeller ,its grip and not grip....if you not pull the trottle of in the right moment... the engine is suddenly at full trottle and no resistance, the engine revs up and the boat and engine is back in Water again ,if all of the propeller is in the water the high rpm is shut down at a snap... this way of driving is killing the lower units and crank . The flywheel is at the top of the engine so all the forces is going trou the crank. A pore analog efi system has difficulties with following this abuse I asume. What I really wanted to ask is: Can I use a PIC to make a intelligent rpm cut or a kind of traction control for boats?

I know this change is commonly made when switching between different OE injectors but I was just wondering from an electronics point of view and driver circuit point of view what this might do ( to reliability, actual pulse width versus commanded pulse width, current/load on the injector drivers, diagnostic system checks etc...). PS - I realize that unless you have an ECU designed for low impedance injectors you can't run low impedance (2 ohm) injectors with an ECU designed for high impedance injectors (although some aftermarket ECU's are designed to work with both).

The Stamp-II has enough speed, gazintas, and gazoutas to handle a simple delta-TPS system with batch fire. It would need ancillary circuitry to interpret RPM into something the Stamp can deal with. Most common temp and TPS sensors are supplied with their own grounds and power, but could be run directly to ground to work as variable resistors instead of variable voltage. I agree it's not suitable for anything very sophisticated, but for a simple Holley Pro-Jection-sorta system the Stamp would work. ------------------------------ Date: Tue, 01 Jun 1999 20:08:55 -0400 From: Frederic Breitwieser Subject: Re: Help on op-amp (?) circuit > So what's the difference between the 2 devices, I have never understood this. > You can use an op amp for a comparator but not visa versa ? The 339 is a dedicated comparer Op-Amp, its designed specifically for switching its output at a certain threshold from 0 to 1 or 1 to 0 depending on how wired... where as the LM334 has an analog swing for an output... and you'd have to buffer its output with a TTL gate or two to interface to 74xx chips, or a CMOS gate for microprocessors.

If you wait a week, you have to sand the whole thing and reapply some more base.

They can sometimes be interchanged, but not always. It pays to read the spec sheets for nuances. The lm324/lm358 opamp works OK as a comparator. But the bi-fet devices, such as lf347/tl082 will phase reverse on the output if one of the inputs gets too close to the rail. Other opamps have a limited differential input range, and often require lots of head-room for the p/s rails. Comparators are typically faster than an opamp (relative cost), and go from rail to rail on the inputs. The only caution I have on the lm339 (quad), lm393 (dual) comparator, is to diode clamp the inputs for protection. Go any lower than 300 mv below ground on the input, and poooofff, no input stage... Easy for noise to do this. BobR. Simon Quested wrote: > > Hi Bruce and All > > > Use a comparotar, something like a 339, I think is the number. Op-Amps > > can get twitchy, for enables.

Just remember going Line I've been fed is the 300+ (not 300, only above) hp 327's got forged cranks in the large journal setups. Read this more than once now in the chevy mags.

Double check that. I believe the , the 749 uses the distributor pickup signal for the rpm sensing. There is no crank sensor in the 4.3 turbo at least.

Could be a stick if equipped w/ the 'electromotive'? (or motec? not my forte but read a long winded tech article), one such EFI control system (very $$$$) allows the exhaust to leak past the valve at idle to create 'some' idle boost.
