    newbie tuning international harvester scout with tbi conversion

    So i am totally new at this, the scout has a 1227747 ecm and is using at present a chip with ANLW bin on it.
    I pulled the bin file out of the chip and have it saved.
    I also have driven it to get a log file now what direction should i head first.
    This scout the way it is setup is not controlling the spark is this going to be a problem?

    What do you mean the scout is not controlling the spark? Are you still using a regular distributor?
    Without the spark module, it'll just control fuel. And for that you need a O2 sensor to rough tune it. You need a wideband for finer tuning.

    I was told it was not controlling the spark however upon farther investigation i have corrected a wiring error and also noted that it was setup to control the spark but still had mechanical advance so out it came and i welded the advance weights down. It is a distributer with a pertronix electronic pickup/ignition module, aka electronic points.
    Now before anyone says you can't use this style distributer for EFI setups they are dead wrong i have designed a interface module that quite nicely runs or shall i say triggers the 8 pin gm ignition module. For $50.00 I'll sell you one, just email me. It does have a oxygen sensor also. I just ordered a Moates APU-1. I was using a ftdi 232rl to data log with but it was too unstable for me. so i just gritted my teeth and shelled out the bucks for what i understand is one of the best setups for GM obd1. it will be here monday i can't wait. I will post more after i tinker with it for a bit.
