Resonance will not make a fuel graph jagged. Resonance doesn't just appear. A motor will ramp up in torque to the point of resonance which will be over a few fuel cells. It will be a hump, nothing more. Are you referring to exh scavenging? Hope so. Acoustical influence on cylinder filling can do st...

Once I got used to this new system, I realized it is a more fail-safe method in a case where you would normally overlook an erroneous reading. Perfect accuracy cannot be achieved by interpolating or smoothing.

I hate the fact that these 750cc injectors have crap for atomization. I had been running stocks on the same system with the boost cut off. I was getting 36 mpg. Now I get about 30. This may not be possible but I was thinking of adding the stock injectors in the manifold and wired to a switching junc...

Not sure what you're working with, but highest velocity will be dead in the center of a straight pipe. I believe you'll be entering a higher pressure area in the boundary layer.

In such in instance if running open loop only, would there be a slight instability or permanent shift in fueling? If so, would it be significant? Never really understood the concept behind the whole thing.

Tried both views, doesn't seem to matter. Guess I should rebuild the .cal from scratch and try.

First of all, is it permissible to use a negative setting on the tps tip-in enrichment? I would like to get rid of some of this excessive fuel under light/idle loads and low throttle angle tip in. I have tried entering a negative number and instantly everything goes rich off the scale and floods. Th...

In turn this will??? Disable alternator or disable ecu control?

For a couple weeks now I've noticed what appears to be a lazy alternator. Once the engine drops to idle sometimes it will quit charging completely, apply a load (headlights, heater blower, ect.) and it will come back to normal voltage. Likely to be one of two things - alternator control issue or sim...

If we want to invite more variables - if not, disregard: Mine had been doing that also on occasion, a daily basis though. Fueling was decent during the event. I noticed something, the alternator wasn't working at all when this happened. Voltage was 12.5v (actual)@ 950 rpm no loads. Turn lights and b...

That crossed my mind, but assumed the volt scale was fixed. Should have figured Calvin to be clever enough that these were adjustable.

In case it's been mentioned before, please point me in that direction. Been having some issues with the battery offsets using RC 750cc sat. injectors. I use an underdrive alternator pulley so naturally the voltage drops more than the norm. By unhooking the alternator and loading the battery, it's be...

Judging by your screen name you've been taking after me...

Ever wonder how many people slap on aebs thinking the flanges align?
