Rising Rate Regulator (Save $100) |
Put simply: incorrect fueling. If you are lucky enough find a RRR that actually does perform a "rising rate" function,
then you will soon learn how it tends to either provide a mixture too lean or too rich in varying conditions. It has no RPM function, and
will never be anywhere near as adjustable or have fuel available at 0.1 lb/in like a 3D EFI can. Not to mention what happens to stock injectors at the resulting high pressures. Click for blown/leaky stock injector photo. |

Manual Distributor Retard |
Your cost is miles per gallon, and engine response out of boost. Possible heat (and thus detonation) problems if there is substantial baseline retard. |
|
Electronic Distributor Retard (Save $250) |
Thinking of installing a huge device made for muscle cars into your engine bay and introduce an increased possibility
of wiring failures? Will never be as adjustable as a 3D EFI. Keep in mind that the SECU has 3D adjustment for fuel and spark in and out of boost. The SECU has faster action than any external box, because it can modify the pulse BEFORE it goes out, unlike an external box which must time sample at least one or two spark events behind to determine timing. |
|
NOS RPM safety box (Save $250) |
Don't need it! The SECU has NOS control built in. |
|
NOS timing retard box (Save $300) |
Retard that is either on or off when NOS is activated? Forget it! The SECU has 2D RPM based spark retard that is active during nitrous injection. |
|
Aftermarket EFI system (Save $1000) |
The cost of user adjustable has been high. I hope you didn't like the daily driveabilty and reliability of your factory engine management, wire harness, and sensors. |
|
Aftermarket EFI system tuning (Save $400-$800) |
Whoops! Your dealer forgot to mention that you would have to have the unit professionally installed, or limp over to a tuner just to get the thing to start, warm, and idle? Want to adjust things for more power or for that new part? Call the engineering team in, cause God himself can't understand the software user interface. |
|
Additional Injection (Save $500) |
Additional injection systems do not compensate for air temperature (they should be re-tuned for every 20deg F change). Usually the additional injector(s) are installed before the throttle body, however the factory intake is not designed to distribute fuel in the intake charge! With the SECU, you are injecting temperature compensated fueling through the factory location. |

Air Temperature Sensor Tricks |
Trying to get more fuel by telling the ECU its cold out? Very little effect or adjustablility, and unquestionably low tech. The ECU will tend to "learn" this out, especially in systems where the extra resistance is always engaged. |
|
MAP Sensor Tricks |
Whether it is with an electronic black box, check valves, or vacuum line rerouting, the trick is the same: Don't let the factory ECU see the boost! Sounds like working backwards, doesn't it? |
