    No. I like to be consistent, I wire both TBI injectors the same.

    Well it's finally time. Engine coming out this week to get the short block done, ordered tuner pro rt and everything from moates. Everything else ready and waiting to bolt onto short block. Dave w is helping me with tune and creating my startup chip. Is there anything I can be doing in the meantime to learn tuner pro and data logging? Unfortunately I don't own any other OBD1 vehicles.

    Download the xdf for your ECM mask Id from this site and start studying the various parameters and parameter comments. You can spend hours learning what you can modify in the tune.
