Best TI Processor for real time control of combustion engine.

Surely you would need something with 2 processors otherwise you would have to switch the engine off to make changes ?

As you've not mentioned about your other requirements but just a need for dual processors; I can recommend you to check Delfino part F28377D mcu which has Dual C28x cores (CPU1 & CPU2) and these 2 Cores have their respective CLAs (an additional processor with limited features). In short 2 C28x cores + 2 CLAs.

Else, if CLA capability is enough; you can check Piccolo parts F28035 or F28069 which have 1 C28x core + 1 CLA.

Let me know if you need more info.

Well a V8 fuel injected motor would at the minimum have to read the following;

Crank angle pulse train ( max 10KHz)
Camshaft synchronisation pulse train ( max 41Hz)
Throttle position sensor (10Hz Analog))

and output the following;

PWM for 8 coils for spark (max 60Khz)
PWM for 8 fuel injectors (max 60Khz)

It would not be able to stop these operations or you would likely damage the motor.

It would be OK to keep the 2 PWM outputs running at their previous ratios in the event of a problem but you couldn't just stop them.

Would the Piccolo be able to handle this or would you need to use a Delfino ?

Piccolo can very well handle the above operations. You can very well try out the C28x with CLA combination.
You can check out : TMS320F28035 & TMS320F28069
