why does TS only provide for 15 injectors

[Yves]

I was looking into things with injectors and duty cycles and one of the things that I was evaluating was a second injector aimed at the velocity stack mouth. However in TS the option in the basic settings only allow for 15 injectors. Why is that. I Always thought that you could run up to 16 injectors...

I have been wondering the same thing. Seems odd.

This has nothing to do with TunerStudio - it is a firmware "ini" issue.

Which firmware are you asking about? Then I'll move the post as appropriate.

Msextra 3.2.4

Msextra 3.2.4

That firmware has been superceded for quite a while.

However, I checked in the current MS2/Extra firmware and the number of injectors is limited to 15 also, this issue dates back to 2003 or so. The next development releases of MS2/Extra will have this resolved - it is a very easy "ini" file fix.

Yes, wasn't looking forward in changing stuff while I was still learning.

Like typing in 16 instead of 15 ...

Reason I ask is that in one of my logs I was running around 67% duty cycle at around 6750 rpm and the engine goes to 7800, so I might get above 85% duty cycle if going to redline.

Now, is this in the firmware that gets uploaded to the ecu or in the maincontroller file of the config map in my project. Bit confusing

[jsmcortina]

It is in the "megasquirt2.ini" file. TunerStudio takes a copy of this and calls it maincontroller.ini

James

[Yves]

So it means I have to reinstall the firmware or just change the setting in the maincontroller-ini ?

[jsmcortina]

Just a one line "ini" edit.

Thanks James, you're the greatest.
