Yes, its alive but more projects, no time to finish this bike. The plan is built a dyno this year to adjust fuel and ignition.

Re: Bi-fue / dual fuel capability?

Yes please. Just to confirm. do you need help to switch between two injectors using FSIO or do you know how to do that based on existing FSIO documentation examples?

Re: Bi-fue / dual fuel capability?

I recall that 2 tables is desirable, with interpolation between the two tables for things like E85. AKA E85 table, and normal petro table, then the E85 sensor tells you where you land between the two tables. I recall the problem with 2 tables was memory space. I recall there was some consideration ...

Re: Bi-fue / dual fuel capability?

Hmmm, could you simply tune 2 injectors, such that injector 2 has a table with 0 fuel until something like 6kRPM, then it starts to turn on, or perhaps the entire table above 6kRPM is 100% injector duty. Once we can´t have 2 separate tables controling 2 injectores i think this is a easy solution. I...

Re: Bi-fue / dual fuel capability?

You may not need the second injector to have a variable pulse width, it you add a second injector and set it to a fix pulse width per rotation you can then carry on adjusting the fueling with the primary injector. As RPM of the engine increases and airflows in the ports pick up velocity the need to...

Re: Bi-fue / dual fuel capability?

how did you figure out that the problem is in low fuel dosage, not the processes inside intake manifold? Because all 2 stroke efi engines have this problem. In high revs the opening inlet time is very short , if i increase injector time duration the fuel stops before reed valve (reed valve close fi...

Re: Bi-fue / dual fuel capability?

The idea is use a small injector for lower rpm and a bigger injector for high rpm, but turn on the bigger injector after some parametres. If you look my table i decresse the time as example because i know with 2 injectores flowing to cylinder i will need less injector time duration. I know this solu...

Re: Bi-fue / dual fuel capability?

Hello Russian I have same problem in my 2 stroke engine. Once 2 stroke have a high range of rpm my injector can´t work good in all rpm band. My question is...it´s possible you add an option on software like this... IF rpm > 8000 and load >50% activate output x (if use throttle version) or if rpm > 8...

Re: Two stroke Efi (#14)

CDI stands for capacitor discharge ignition? Do you have a scheme with part numbers? What are the pros and cons of such solution? Does it need a magneto? (It seems to be rectified?) Do you use O2 sensor in this setup? As far as I remember, older models of JAWA required adding oil to gasoline for lu...

Re: Two stroke Efi (#14)

I´m using usb on Frank now, finaly is working. When i start engine after few seconds i have this warning "Protocol error" . When this happens ts come slow and sometimes loose connection.

Maybe noise from generator/spark coil/vr sensor?
