Boost / VVT / other 3D control
Another subject near and dear to my performance needs is boost control. In the 70s and 80s, and for some even in the 90s still, boost on turbo-charged cars was pretty much controlled by a mechanical wastegate. A wastegate is a flapper (valve) that sits between the exhaust manifold and the downpipe, ...

Re: Alternator control
My MS3 only checks every 10ms (user setting - see image). And as Jason says, a magnetic field works as an integrator anyways, so we have a fairly long time constant. MS3 code works very well indeed, but we don't really know what they're doing. Please note that the graphs on the right are not used. E...

Re: '99 (and '03 Miata) in Eastern PA
As a matter of fact I already downloaded all your schematics!
Thanks

You may have to make it 5 lines- Jason is also using 50mV hysteresis.russian wrote:...
Interesting! Too simple to be true, but I'll definitely try this since it's just 3 lines of code! 100Hz loop frequency is totally not a problem.

'99 Miata in Eastern PA #17
Last Saturday Andrey personally delivered my Frankenso board- thanks! I will hopefully have it hooked up to the car before HPDE season starts. I currently have two Miatas, one of them is not subject to emissions testing anymore, so this will be my first victim for a rusefi. About the car: '99 green ...

Re: Alternator control
Has Sturovo ever managed to get his '99 NB Miata control working with the rusefi? Over on miataturbo.net is a discussion on alternator control specific to NB Miata. I believe this is what was eventually implemented in MS code as the "High Speed Feedback Field Control" feature and works a t...

Re: Acceleration enrichment
First of all, you should be able to get the car running well with just TPS and MAP based settings. IMHO the wall-wetting algorithm is the icing on top for the last 5% of perfection. On my MS I use TPSdot based enrichment to deal with the initial "Tip-in" spike in AFR. MS doesn't even have ...

Re: Compatibility with Virtual Dyno - ticket #266
I'll volunteer to contact Brad Barnhill, the lead developer behind Virtual Dyno to add a config for rusefi. I guess for that we'd need to decide what signature to use in TS.

Re: Compatibility with Virtual Dyno - ticket #266
On the other hand, Virtual Dyno has a multitude of different log file definitions it's already using. So rather than using mimicry to pretend to be a different device, maybe we can get the developers of VD to include a specific rusefi log type. This would of course require the signature to be someth...

Re: Compatibility with Virtual Dyno - ticket #266
It certainly looks related. The version reporting in TS seems to come from line9 in file "Tunerstudio/rusefi.ini"
signature = "MShift v0.01"
Suggestion- change to:
signature = "MS3 Format 0523.15 "
Not sure why my MS3 has the <space> at the end.

Compatibility with Virtual Dyno - ticket #266
Many users of Megasquirt and other efi systems use the virtual dyno software ( http://www.virtualdyno.net/ ) to obtain fairly good estiamtes of torque and horsepower. Virtual Dyno is a great tool for street tuning in addition to professional dyno tuning. It essentially looks at the rate of increase ...

Re: Acceleration enrichment
At first glance it looks like the Acfuel shot should be long enough. Are you sure the fuel cells you're hitting at the end of the accel (close to 100kpa) are properly tuned steady state?

Re: Alternator control - PID implementation
I probably missed a lot of other discussions on this, but what type of input does your alternator expect? Have you scoped the output from the OEM ECU?
