    450RWHP Fiero. Joe, what do you think that thing would like like launching with a set slicks on it. Didn't someone stuff a northstar V8 in their Fiero already?

    John,

    the power:weight ratio would be VERY advantageous .
    I think I heard that someone dropped in a Northstar, and also probably a SBC 350.

    Fiero groups are very resourceful (sometime in the 80's I ran into one group that were designing and fitting their Fieros with a home-made fuel injection system (they were building their own microprocessor hardware and writing their own embedded software).

    My hat goes off to these guys.

    will there be a PID or someway to log what this spark scaler is?

    Under the Spark section there is a pid called 'High/Low Octane Adaptive Spark Scaler {GM.ASPARK}'

    This is in version 7.2.2 Patch 001 at least. Just went looking for this today also...

    Installs already done to the Fiero

    3800SC Series I, II, and III (any transmission)
    NorthStars 93-01 (any transmission)
    SBC (any transmission)
    LT1 (any transmission)
    LS1 manual only

    In developement today here at FastFieros is the LS1/LS6 on a 4T65eHD with complete OBDII system.



    This is one reason for the need of the EFILive Flash. A custom OS may need to be designed for this. I have my thoughts on how I will approach this already using the truck product line PCM's.

    This was the Series III 3800SC I installed last September

    I got my son a red 1985 Fiero GT for his 17th birthday. I wanted him to learn to do some mechanic’ing, but I initially gave it to a "professional" to solve whatever immediate issues it had.

    What a mistake.

    To make a long story short... he kept it for almost two weeks trying to fix a whiny electrical sounding noise (the fuel pump). I ended up taking it back to my house to troubleshoot myself I (very little time on my hands these days).

    He had installed the pump and left the left the fuel strainer/sock off. :x He nor a "electrical specialist" he had come over couldn't figure out why the pump was running all the time... even with the ignition off. By now we'd both checked the actual wiring inside the tank, and I traced up the harness to inside the car... looked good.

    I replaced the relays (heard they are good to replace when they are old anyway, and they are cheap). The pump ran even with the new relay out... only by removing the fuse for the pump would it stop. OK... there MUST be an alternate current route.

    After one afternoon of troubleshooting I figured out from the wiring diagram that the oil pressure switch is a backup power route for the pump in case the relay fails. I removed the oil press sw and voila, the pump stopped running. I replaced it ($32) and now that works fine.

    But, when the mechanic thought the whining noise was the alternator :roll: , he had me buy one and replaced that.
    You can't run the car 10 minutes before it's chewing the last rib to the outside.

    I took the old alternator to be checked and, as I suspected, it produced 15+ volts. I'm gonna take the new alternator off and put the old one back on for now (the bushings are kinda loose, but I know it won't eat belts) and see what they did wrong while I take it off.

    BTW... Autozone had to give me a OP Switch for an '86 to get the right one (3 conductor). When I asked for an '85, it called for a 2 or 1 conductor option. :? I wonder if it's just the wrong alternator, too. It looks like a slight alignment problem. Any alternate :wink: :lol: issues you can suggest to me would be helpful.

    Thanks!
    I'd rather be blown, bored... AND stroked!
    Now: 447 CID (Corvette 427) , ATI Procharger D-1SC Supercharger

    And GT stripes are also good for 10 HP...

    No, seriously, a Fiero is a light car, and stuffing in an LS1 will make it haul
    (let alone putting on a turbo or two as well).

    These Fiero guys are pretty serious and do good engineering; see photos above.
