The system does include coolant temp & RPM.
When we made the new exhaust system we fitted a socket for the O2 sensor.
This was plugged in during the dyno runs to get the correct fuel/air ratio, but the Motec does not use it.
The MAP feeds off of a vacuum port on each throttle body.
I’m pretty sure it’s for atmospheric pressure correction.
The Motec has provision for more sensors & given more time in the future it will be expanded upon to refine the tune.
Inlet air temp sensor is possible, could be fitted above the velocity stacks, or in the side of one.
I also have a cam angle sensor which plugs in where the Distributor was, not set up yet.
There is a spring loaded connection between each throttle body that has a screw adjustment for synchronizing.
I’m not right up on the tuning of this system & I need to learn a lot more.
It’s been a steep learning curve.
I have simply done all of the mechanical side & the manufacture of components etc.
I have a friend who does the electrical & another who has tuned on the Dyno.
So I rely heavily on them for tuning input.
Kelly, your comments here are most helpful, the more information the better.
I like the Kinsler throttle wheel that would give a nice progressive feel.
I did consider a vacuum pump but was trying to get it right using manifold vacuum & reduce the number of electrical accessories.
I may need to chase down an OEM type vacuum pump from a modern car.
We are machining up new rims right now, (17x9.5” front & 19x13” rear).
I have some 8 piston Brembos to put on the front; they tuck nicely in the 17” rims with big Wilwood rotors, so I will need good vacuum supply.

Tony.
Very well done!
