    1984 Pontiac Fiero Indy - "CarP"

    This is my first project involving a carputer so this is where I'm at right now. I'm an old school IASCA competitor and SQ/install judge from the early 90s so drawing from that this isn't/won't be a real showy fibreglass thing. I want it to be "stealth" so to speak and as clean/unabtrusive as possible - like something that would have been built back then.

    The system will mostly be high end equipment from the Fiero's era that I've had for a very long time (some of it won me trophies back then), except for the front end - it will be a "carputer". The core unit originally was an Acer Aspire One netbook with a touchscreen addition. I have really gotten into PIC microcontrollers as of late and this car will have no less than 6 at different places. The carputer will get main control from 2 of them, along with the alarm built from scratch and a new "BCM". The carputer also has GPS and a custom software front end running on XP. It has been tweaked to go from key-on to playing music in 44 seconds from cold start, 14 seconds from standby start.

    The System

    - Acer Aspire One netbook - 8GB SSD upgraded to SATA HD plus touchscreen addition. Computer is completely dissassembled and framed into a new chassis.
    - Precision Power PEQ223 preamp - allows quick manual setting of volume/tone balance.
    - Alpine 3401 parametric EQ - set-once using an RTA.
    - Audiocontrol 2XS active crossovers x4
    - Audiocontrol EPICENTER and ESP2
    - Precision Power AM series amps (high current sweeties from 1990 era)

    Audio will be all active crossed over to 3 tweets, 3 mids, 2 mid basses and 2 10" subs.

    The console is the main part currently built (minus a few finishing touches).


    Some of the early chaos


    The console skeleton.


    A front hinged compartment holds a mini keyboard, touch mouse and control panel (early pic).


    Mostly done - the console is completely new front to back.


    The startup screen. Also the 3 gauges are scratchbuilt - the movements are the Princess Auto ones (with water temp recalibrated to the OEM sensor) with needles from a late 80s Firebird cluster. It actually looks better than in the pic - the glare was bad on these pics.


    The front end I wrote playing music.


    This is the heater control page. The Indy originally came with air so the controls were all electric other than temperature control so it was all doable.


    Still some labelling to do here but the left bank of knobs is audio control (Epicenter, ESP2 and canter/sub control). The right bank is a PPI preamp. Switches are windows, headlights, rad fan, defrost, etc (this is where the microcontrollers will be doing their work). That isn't all completed yet. The labelling will be done with "Decal Pro fx" - it is tedious to use but the results can be remarkable.

    The back part of the console with the center cover removed, revealing the EQ. I always wanted to do this with that EQ but never had a car with a console wide enough.


    The cover replaced. This also shows the new fusepanel's new location. That back part of the console hasn't been done yet because I'm not sure how it will integrate to the new back wall (where the subs will be).

    The speakers will all be stealth/hidden. In my last car I did a trick with the midbasses under the dash which necessitates moving the OEM fusepanel, hence the new one. Also in the next few years the main cluster will be replaced with a custom one with gauges matching the three in the center - that's why the defrost and headlight switches are going in the center.

    So there it is. Still a lot to go but the console was one of the bigger jobs. Feel free to comment.

    Anytime man, great to hear from you - I'm hoping the GT boys can put something together in GTA or north of that before the season is out. The Niagara and PTBO meets are just too far for me at this moment.

    The switches are from Digikey. There have been a few versions of that area, this was the final version. The nice thing with these is the white panels are backlit, so when all the labelling happens in the winter the switch functions will be printed right on there and lit through.
