Forced induction

[Frederic Breitwieser]

Of course.

You can choose one or multiples of the following:

1. Use a rising rate (variable) fuel pressure regulator so that as the boost
increases, the fuel pressure goes up approximately linear to the boost.

2. YOu can use larger injectors, and change the idle and lower RPM fuel maps
to accomodate the larger injectors, as they will overfuel for idling and
cruising around town.

3. YOu can use the same injectors, if the boost isn't that much, and edit
the pulse width tables and increase the pulse width for higher RPMs.

4. And if the boost is under 5-6 PSI, you can actually just "slap" the
supercharger on and not worry about it.  Paxton and Vortech kits do exactly
this, though they often recommend a chip upgrade.  Most stock OEM cars have
enough "play" built into their tables that they can handle additional boost
in moderation.  You would notice a lot of "kick" off the line with a blower.

Is it possible to modify the ECM parameters in a stock 93 Camaro Z28
computer to support forced induction (specifically turbocharging) with
larger injectors, without using an external fuel management system?
