I recently had a rather detailed discussion with a friend that really wanted to up-grade to mpfi
but after looking into whats required he decided the cost may out weight the potential benefits.
hes already purchased the MPFI intake injectors and throttle body,
KEEP IN MIND THATS MPFI...
which has AN INDIVIDUAL INJECTOR FOR EACH CYLINDER,
LOCATED IN THE INTAKE RUNNER ,
FOR EACH CYLINDER
,NOT THROTTLE BODY INJECTION
which places several fuel injectors in the throttle body to spray fuel similar to how a carburetor disperses fuel,
from a centralized location on the manifold plenum.
its the controller and wire harness and sensors that seem to be his major issue here!
now I freely admit that the costs are far higher but the benefits are there so its simply a question of how to bye-pass or reduce the cost of the components required yet still produce a desirable combo fully capable of easy tuning and precise fuel management and ignition curve controls.
theres certainly ways to buy components and build a custom EFI CPU.
so lets discuss options, experiences failures , successes and ideas, cost and difficulty in building an EFI control computer that can be easily tuned on a kick butt, EFI intake , and one that can be easily used on a super charged engine , the sensors, fuel system, fuel pump, matched ignition etc. if thats required
Id also point out that any decent controller should have the ability to be programmed too use BOTH low and high resistance fuel injectors and options too allow several kinds of sensors (TPS,IAC,COOLANT HEAT,PLENUM VACUUM, AIR TEMP,IGNITION ADVANCE,ETC.) too be used if its going to versatile rather than single brand
compatible
