Understand Advanced Engine Calibration and Fuel Systems

the tune on this engine so when we're going through all of our base uh calibration work with with spark fuel all that we can monitor what's going on inside of the combustion chamber during all of our development work so we know if we're getting any kind of knock peaks at certain rpm ranges certain loads we know that we've got to do some more calibration work with the spark tables the other thing it allows us to do is is to make sure that we're getting a correct flame propagation inside of the combustion chamber you really want to aim for a mass fraction burn of 50 so that what that means is anywhere from eight to 11 degrees after top dead center you really want half of your combustion process already through it's through the process so you want to time it in a way to where yes you know you got you got some serious like data measurement going on here a lot a lot beyond what i thought you did here like even for me yeah this is this is like some serious serious stuff yeah so so it really is oem grade equipment i mean there there aren't a lot of companies out there using this avl equipment you know you obviously got your oems uh ford gm chrysler they're all using this stuff yeah it's really a great tool for us for all of our calibration work it really lets us refine the tune the engine is going to be safe for the customers we can we'll go through multiple different fuel grades we've got 87 octane on a switch we've got 91 octane ready to go we'll build spark tables for each fuel so so when we advertise an engine that says 91 octane only we've done the development work to know that if you put 87 octane in it you're gonna knock it so with our new fuel systems that we're working on we'll be able to switch so we'll have knock sensing into the system to where if a customer like ah yeah i know you say 8 91 i can't i can't get to 91 i got to put 87 in it today the knock sensors are going to pick that up and they're going to pull timing out of it and run a different timing table so it makes it makes our engines really bulletproof which is what we want we we're just really trying to eliminate anything that the customer can do wrong to accidentally hurt the engine so this is like an aftermarket oem powertrain like this sounds a lot like a factory computer yeah it kind of has all the fail safes in it but this is like a aftermarket drop-in yeah so so that's that's the idea it it 100 is an oem ecm what is that you got a transmission on there yeah so uh we've recently…
