(05-04-2010, 10:28 AM)DervTuning There is no transmission interface, as I will be using the Getrag 5MT from the 16 valve.
A transmission interface, that is, some sensor(s) that tell the CPU whether you are downshifting or upshifting, and into which gear, would allow the computer to automatically match the rpms to those required by the gearbox. This would extend clutch life, protect the transmission, and be really fun to drive.
DervTuning That is a good idea about the oil pressure, thanks! It should be able to interface the oil pressure sensor signal to limit the fuel to the idle setting or shut the engine off completely.
The oil pressure thing isn't only to protect the engine if it springs a leak. If there is too much torque at too low rpm, you will damage the engine's "internals". Assuming you have infinite air (which a well-designed compound or VNT system should be able to approximate), you could get a LOT of smokeless torque at really low RPMs. This would be bad, because it will cause metal-to-metal contact on various bearing surfaces and massive side loads on the cylinder walls. If the engine RPM is low, so is the oil pressure. Monitoring the oil pressure will give you an input to construct an oilPressure-boost-egt-modulated dynamic max fueling curve that depends on the fundamental engine operating characteristics, as they are at any given moment. The problem is then to figure out all the forces involved and what is your max torque allowable at a particular RPM
.EDIT: This is all assuming the ideal is maximizing smokeless performance. You could just slap on a huge turbo that doesn't spool until 4500rpm and call it done.
