sequential

Post by magaiverbrasil »

In ms2 If it is possible to use tooth wheel in the camshaft, why use second tooth wheel in the camshaft to make sequential?, with only one tooth wheel in the camshaft is possible to code know for example that 60-2 , missing tooth is first cylinder fire ?

Yes, a missing tooth cam wheel is sufficient for sequential injection.

But a cam wheel will always be less precise than a crank wheel due to cam drive mechanism. There will always be some sort of play in whatever mechanism is used which can cause position errors and jitter.

I assume you mean a single wheel with missing tooth at cam speed; it's already there and has been from the beginning.

Yes , i use only one missing tooth wheel in cam , how to enable sequential in tuner studio ?, I already did change mod in ms2 daughterboard with 4 injector driver for sequential .

changing untimed inejction for sequential / semisequential and standard drivers for additional drivers, single wheel missing tooth (60-2) and change wheel speed to cam wheel, will now work sequential 4 cyl?
