How rich do you think you can run it? If it's overly rich you reduce power which reduces exhaust volume and adds lag.

I have both problems. The hot start. I crank for a couple of seconds and then WOT (past 70%) to clear. Only way mine will start hot.

As for the miss, exact same thing. Mines a pulse width spike. I have a post here. http://www.msefi.com/viewtopic.php?p=138429#138429

You will want to pull timing when entering boost. A few psi at full advance won't hurt but you don't want to run 38* at 7 psi unless you have really low compression. On your log, spark angle looks to be your timing based on the numbers.

Peak power is around 12.5. A little richer doesn't cost much ...

I ran 90% duty cycle before MSII for a few years. Same injectors with MSII I went up to 114%. I swapped them to larger and am now in the 80% range. Based on that I would say you are fine at 71%.

You want the timing to increase with revs till around 3k or so where it will be all in. Then as boost ...

Would this also allow me to use one of the gauges to view it in real time if I configure it in the ini file too?

How do you log knock?

I'm running MSII, 2.36MT. I have a knocksense with it's output going to JS4. Is there something I need to turn on other than knock settings under sensor calibration? I didn't see anything in my log.

I put the 680's (actually they flowed 700cc) back in. My fuel requirement is 4.8, 2 inj per cycle alternating. Idle fuel is 32 at 600 and 1300 rpm and 40 and 50 kpa. Timing is 10*. The AFR hunts a little at idle but seems to do better if it's on the rich side, upper 13's. Engine has 500cc per ...

I'm running 550's now. I have a set of 680's that I started with but the idle wasn't so great so I swapped them before the firts drive. I think I'm going to have to put them back in as I plan to run more boost when not running pump gas.

Thanks, that makes more sense. AFR's were good.
