    I could convert my amc 304 engine to tbi.When I used the original spark advance table from BPSA.bin the car didn`t run right. I have set the table according to the spark advance curves from the jeep-manual. Now it runs good when rpm is higher than 2000.At lower rpm and when accelerating i have to do that very smooth otherwise engine is bogging and trends to stall.I raised up spark advance in lower rpms slightly but no success up to now. When I take an other bin (bhmc) from a 5ltr engine, engine will not accelarate at all.
    Attached my last logfile where ve tables are not yet set by trimalizer.
    Don't waste your time using any of the stock Chevy timing maps. To be honest, I know nothing about AMC engines and what they like for spark timing. My approach to this would be to do a Google search for a AMC 304 spark timing table. There was one hit that I saw that they were using megasquirt. Perhaps you could experiment with that. https://grassrootsmotorsports.com/fo.../118096/page1/

    Arghh...just reread it's referring to a AMC 360...
