First off, I am not anywhere near an expert in engine building, cam selection (how duration and lift affect the motor at idle and driving), injector flow rates, etc, etc, etc... So now that I have that out of the way, I still want to figure out the bits and parts that ***may*** make it possible to run a 2270 motor with LH-Jet. The primary reasons I am looking at this setup are because:
From my research, LH-Jet 1.0 was pretty rare and used in the early 80's but then a switch to LH-Jet 2.0 occured. The primary difference between the two was that LH-Jet 2.0 utilized a Throttle Position Sensor (TPS) whereas LH-Jet 1.0 did not. 2. If LH-Jet 2.0 variant is the desired setup, which sub-variant would be used? There appears to be a couple sub-variants within LH-Jet 2.0 primarily consisting of LH-Jet 2.2 and LH-Jet 2.4. It appears one of the primary differences between the two is that the LH-Jet 2.4 utilizes a "trigger flywheel" and the LH-Jet 2.2 does not. What exactly a "trigger flywheel" is I am not sure....I am guess that this is a notch or mark on the flywheel that is monitored by a sensor with the data fed back to the ECU. 3. What would the "build" sheet look like for such a setup? Of course, this list can get complicated, but the desired build here is a street car with spirited driving. I would want excellent low-end torque, around 140-150HP on the motor and good pull all the way through the RPM range up to XXXX RPM (not sure where redline would be). Note also, the car will remain as a narrow body with 4-lug wheels.

I can't help but wonder about the Megasquirt (or even Microsquirt) thing. You are looking at doing something that hasn't been done much, vs what has - and has been proven. It sounds like you think MS is complicated and you are afraid of it, when it seems to me it is simple and proven?
But I love it that you are looking at something new. Always love to see that. Look forward to hearing what you end up with. |
