Sequential with additional drivers on an RX-7 FD
Is this a supported configuration?
Ie 4 injector drivers
Sequential/semisequential
Set to additional drivers
Ignition set to wasted spark, rotary mode set to FD.
I can't seem to find ANY info about sequential with 4 drivers in the manual for rotaries with staged injection for the MS2.

Re: Sequential with additional drivers on an RX-7 FD
On the MS2, 4-channel staged sequential is 2+2, channels 1/3 + 2/4. I don't see why that would be different for rotaries vs piston pushers.

Re: Sequential with additional drivers on an RX-7 FD
Trailing ignition stops working on the stim as soon as I enable sequential with additional injectors, hence my question.
It starts working again if I disable additional drivers and sequential (ie untimed injection).
Also, RX-8 mode is no longer an option for the rotary ignition options, but it is still mentioned in all the manuals.

Re: Sequential with additional drivers on an RX-7 FD
You can't run sequential injection on rotaries with ms2 the only way it's to run no split if you want sequential injection and split you need ms3

So wire both the leading and the trailing coils to the same ignition output?elturbonitroso wrote:You can't run sequential injection on rotaries with ms2 the only way it's to run no split if you want sequential injection and split you need ms3

Re: Sequential with additional drivers on an RX-7 FD
Yes or run no trailings, but on rotaries engines your not going to see a big difference running them on sequential injection like on pistons engines,also you have to set your ms2 to piston stroke 2600cc and 4 stroke.

Re: Sequential with additional drivers on an RX-7 FD
The rotary ignition code uses the same CPU timers as the extra injectors so you can only have one or the other.

Thank you Jean, that explains it.
What about the missing RX-8 mode though?

If you want to use 4 individual coils select c.o.p in the spark output

That goes counter to my experience. Injecting at the right time can allow you to use a lot less fuel for the same AFR.elturbonitroso wrote:Yes or run no trailings, but on rotaries engines your not going to see a big difference running them on sequential injection like on pistons engines,also you have to set your ms2 to piston stroke 2600cc and 4 stroke.
Megasquirt is not for use on pollution controlled vehicles. Any advice I give is for off road use only.

Re: Sequential with additional drivers on an RX-7 FD
If you inject the fuel at the right time yes,but if you don't mess with the injection angle you are not going to gain much and that's what a lot of people do.muythaibxr wrote:That goes counter to my experience.

Re: Sequential with additional drivers on an RX-7 FD
The whole point of having tunability is to use it - right?
That's a similar argument to saying "ignition control has no effect, I set my whole table to 20 degrees."
