I had a good running setup, but I didn't like how I was running out of timing table values when I was just getting into boost. So this is my first attempt to scale a tune, I watched Chopper Doc's videos about it on youtube. Seemed like I followed everything, but I can only get it to start for a second, then the injector pulse drops down too low for it to keep on running. I halved the size of the engine, halved injector flow rate and halved my ve table among a few other things. I will put up a tune of it first when it was running good before I tried scaling it, then what it is doing now. I have tried adding back in more cranking fuel and increasing the ve table values, but it keeps on stalling real fast. Any help would be appreciated.
thanks kevin, I put the cylinder volume back to what it actually is and it started right up and afrs are right where they should be. And now it shows my cylinder airmass is like 16 at idle and it was low 30s, so I should be in good shape.
