6500 RPM... for now That I can adjust easily

I adjusted your rpm and map values for the fuel, spark, and afr tables.
Try flashing this msq and use it to start tuning.
Edit: Are you using an output to drive your rad fan relay?
VRin: This circuit is designed for use with alternating current variable reluctor AC signals that have both positive and negative voltage components. For more info, see the ignition pickup page. This circuit has two sensor connections:
VRIN+ (coax cable center wire) on pin 32, and
VRIN- (coax cable shield) on pin 33.
(Some older diagrams may show these reversed - the text here is correct! It is also possible that some early production MicroSquirt®'s were mis-wired from the factory. Check the coax cable against the Ampseal pins to verify yours are correct: shield to pin 33, center wire to pin 32. If they are backwards, you do not need to swap them, just use the appropriate pins, i.e. the shield for the input (pin 32), the center wire for the ground (pin 33). If you prefer, you can swap the coax pins to be 'correct'. It takes 3 minutes to do. All you have to do is pull off the red clip on the harness connector, this will expose all of the pins. Next, find the two pins for the coax shield (pin 32 if it is backwards) and center conductor (pin 33) and *gently* wiggle them while gently pushing the terminal - it will dislodge and push back. then switch the locations and push back in till it clicks in place. Then reinstall the red clip (line up all of the terminals).)

The coil's primary current can generate a lot of noise inside the MicroSquirt. The whole MicroSquirt® setup is very compact and noise coupling in the wires can be of concern. Running this wire (and the IGNITION OUTPUT #1 where appropriate) in their own shielded "conduit", along with the injector outputs, can substantially reduce noise injection back into the tach circuit. You can buy shielded wire for this, or wrap 2 to 3 layers of aluminum foil (have a look into your kitchen) around the wires and connect the shield to ground.
