Question Spare PWM Map

Looking for a way to translate a 2D table (rpm vs map) to PWM. Is there anything left in there for me to do so? I don't see anything obvious, but perhaps there's something tricky to be done. Thx

you could hook all the injectors up to 1 channel, change to 1 squirt simultaneous and utilise the dual tables.

One table for fuel the other for whatever you want to control via PWM

What's the table for?

Sounds like a bad idea for economy and emissions.

VVT. If no one wants to buy my 01 head, I can use it and sell my 99 head.
Something else I've been considering is perhaps a 2nd MS that got power, ground, map, and tach to do what I need via an injector channel. Or even something like a EMB. basically whatever I can get the cheapest.

A VVT controller should be a very simple device. I keep saying, I don't understand why there's not a controller on the market.

Take a LM2917 chip feeding the tacho in then hook the linear output voltage up to a relay?

Lose the EBC, and use the EBC map.
