> Suggested: Two stage fan control. This can easily be done. I have
already added single fan control to the program. Due to a limitation in the
number of outputs on the basic unit, dual fan wont be done. In the faicier
version this could easily be added. For AC useage, might I suggest
attatching one fan to the AC compressor clutch so that when the pump is
running one fan runs. This will prevent the condensor core from overheating.
>
> Suggested: Include list of standard parts/sensors. For relays any 12
vbold dc relay with greater than 30 ohms will work. Sensors use a any
variable voltage MAP sensor, Any continuous variable resitive tps sensor,
and a temp sensor for a 79-85 gm temp gauge (same resistive characteristics
as most gm efi temp sensors but with simple connector).
>
> Suggested: Turn on for heated O2. Since it must be on when the enine
is running, just connect it to the fuel pump power.
>
> Suggested: Make it compatible with points or magnetic trigger. I was
planning to do this.
>
> Suggested: Have one screen status while tuning so immediate feed back
can be had. It does this currently.
>
> Suggested: Closed loop. New version will most likely have this. A
PID control routine must be developed that will fit in my small memory space.
>
> Suggested: Torque convertor control. This could be programmed. I
need to know when one would need to be locked up and when it would not in
order to make a control routine. Any help?
>
> Suggested: Turbo waste gate control. Would need more info on how
actuators work to make a control routine. This featur may have to wait
until a future version of the control, but it would be possible.
>
> Suggested: Ignition retard under boost. Is currently handled by the
ignition timing map for the system that will have ignition control.
>
> Suggested: Make MOS control RPM adjustable. NOS turn on point is
controlled by rpm, map, and tps. Multiple NOS stages could be added.
>
> Suggested: Direct ignition control. For the engines that have the
smart coil pack and control. Engines without the smart coil control will
have wo wait until I can develop a 332 based engine control.
>
> Suggested: Make source code and schematic available. I do not know of
any one that does this for a specialized product like EFI. In this type of
markey, it is too easy copy and sell ideas. I will have to think about
doing this if possibly a confidentiality agreement would be signed.
