Bobby,

With my Renesis dual wheel trigger setup, tooth #1 is the first tooth on th= e 12 tooth (crank) wheel after the signal from single tooth (cam) wheel.=C2= =A0 The crank and cam signals are actually generated by a single wheel on t= he E-shaft.=C2=A0 The angle of this tooth #1 relative to TDC can be specified in the setup.

The TPS input code has been changed to add or subtract from the pulse = width after all other calculations are made in order have it act as a manua= l mixture control.

I also changed the VE table so the cells all are 100 initially rather = than reflecting the MAP percent of the sea level pressure.=C2=A0 The MAP pe= rcentage is now applied before the VE table values are applied.=C2=A0 For e= xample, the original table value would have been 50 if MAP was half of sea level.=C2=A0 This makes the VE table act li= ke the EC2 mixture correction table.=C2=A0 Changing the values in the VE ta= ble to values less or more than 100 delivers less or more fuel compared to = what would be delivered as calculated from the displacement, MAP, intake air temp, and desired AFR. =C2=A0

I'm not sure what table 1 and table 2 would refer to in the Speedu= ino - MSDruid cell phone app system I'm using.

Another question Steve. When you switched th= e code for TPS are you using it in blended tables where table 2 is Alpha=E2= =80=93N, TPS and table 1 is MAP based? Or are you running pure Alpha=E2=80=93N? It appears a second MAP sensor can be wi= red in externally and left open to the atmosphere for altitude fuel compens= ation. =C2=A0

Charlie,

I changed the code in the Speediuno to use the TPS input to give man= ual mixture control from a potentiometer and it works fine, both with a Spe= edysim board and with the actual running engine.

Yes, my idea would be a= n opamp confgured as a summing amplifier, with the wideband on one input an= d biasing voltage on the other.

The TPS sounds simpler,= if that will work.

The O2 sensor outputs a voltage but very little curr= ent.=C2=A0 That would make it difficult to bias it in a predictable way.=C2= =A0 Biasing a buffered output such as a wideband O2 unit output would proba= bly work.
