dyno tuneing mainly works for peak hp at full throttle.

dosent help for partial throttle.

street tuneing :-)
with your own wb02, egt, logger.

 

you can also log rmp, and 5 other 0-5V inputs and it has a narrow band output.

 

I can vouch for the autometer A/F being basiclly worthless, it said my car was running extremly lean so I added fuel, anyway the short story is that the car was running SO MUCH fuel it was almost dieing at 1psi. the A/F meter said it was too lean, but the plugs said rich, so I turned the fuel down and bingo, it was WAYYY to rich, runs great now, but still needs some wideband tuning, I'm just chillin at 6psi for now...
