Federal smog laws GregO'Connor

I spoke with a Diesel electronics tech about clearing up the
acceleration smog puff on my bus.
The stack puffs smoke untill the turbo speed winds up fast enough
to pump sufficient air to burn all the fuel that is being dumped at
the piston. the fix is regulating the electronic injectors to not
release more fuel than can be burned at a given time. To back off
the accelerator is not a solution because:
To add more air ;you need to push the fuel in ;to fuel the fires
hotter ;to blow and build more exhaust pressure past the turbo ;to
turn the turbo blade faster ;to pump the more air in.

I recalled DavidBrady wrote about a turboSpeedSensor code from his
ddec. That sensor is not part of the older DDec input prompts. the
computer must recognize turbo speed in the resulted release of fuel
the computer allows the injector to piss at the piston. Mass air
flow and turbo speed are more variables in regulating the fuel
released as per a given ability to burn. You begin to realize the
value of these and even engine temp as factors to efficient
acceleration, fuel economy and permission to operate.

I noticed a page on the CARB site about reprogramming updates for
ddec computers and older electronic Cats for comercial vehicles. I
dont know if it is just an allowable flash update or a required
update.

My interest is not compliance to a law many have pointed out only
apply to commercial vehicles. My interest is to not attract
attention with a puff of smoke at acceleration.
