Hi Group,
Anyone out there in to automotive applications and willing to

is not a dedicated microcontroller and
is too slow for most critical timing applications. This rules out most engine
controls applications such as injection
or ignition.
We looked into some non-critical timing projects, such as turning on and off
some solenoids based on engine rpm and
load, like a 3D table. We haven't had time to actually build it tho.
What projects are you looking into?

I have two projects in particular in mind right now. The first
is relatively simple. Many of the newer cars on the market now have a
display that will show current fuel economy, and average fuel economy
since last tank fill. This can be done if you know injector duty
cycle, injector flow rate, and distance travelled over time. It
should be relatively easy for the Stamp and a floating point
coprocessor to do this, and output to a serial LCD display.
The second is considerably more complex, but I think still quite
within the capability of the Stamp, or multiple Stamps and some
periphrials. It is a semiautomatic controller for an electronic
controlled automatic transmission. It invloves switching hydraulic
solenoids off and on, as well as a PWM controlled solenoid, with
inputs from throttle position, vehicle speed, engine speed, and
operator controls.
The reason I've turned to the Stamp is that after much research,
I haven't been able to find anything on the market that will do these
things. I have a mechanical and electrical back ground, but no formal
training in electronics or computer programming. I've bought myself a
Stamp and prototyping board, all the Stampsinclass curriculum, and
the books by Edwards and Williams, and am in the process of teaching
myself about Stamps and PBasic. It's slow going for an old dog like
me, but I'm making progress, and am optimistic I can make this work.
I've already built a prototype transmission controller using a
little "Cube" PLC from Seimens called "Logo", that works quite well,
but it has reached the end of it's limits, and I nedd more features.
An HC11 would probably do just fine, but I don't have the knowledge,
or time to gain it to try that. Hence the Stamp.
I know what I want to do, just don't know quite how to do it
yet, and thought perhaps there may be others with similar interests
that could gain some mutual benefit.
Regards,
Robert

the A/C compressor. My truck came with an engine-driven fan and I switched
it to electric with a thermostatic switch to control it. I don't like the
way it works because you could be stuck in traffic, the fan will start, and
then when you get back up to speed the fan will keep running even though
there is more than enough air rushing through the radiator due to the
forward motion of the truck. So I want the stamp to monitor coolant temp and
vehicle speed and only run the fan when necessary. Also, I want the fan to
run the fan if the A/C is on, but shut it off when the vehicle speed gets
above 30 or 40 MPH.

the gas -- this gives you more passing power on these anemic things they
call cars.

that the compressor shuts off at WOT on my truck. If not, I'll certainly add
it.
