Speeduino ECU Tuning Guide | Part 12: Using Autotune CORRECTLY to tune fuel | Megasquirt, KDFI etc.

#ecu #tuning #megasquirt

In this video we will be showing how to tune Fueling using the Autotune feature within Tunerstudio for all ECUs that use this software such as Megasquirt, Speeduino, Microsquirt, KDFI, RUSEFI etc.
and how to actually PROPERLY use this feature so that it makes sense

Thank you so much. I now understand the difference between a base map and the tuning and refining that goes into making that base map better.

And also appreciate you doing this in English which I’m guessing isn’t your first language!

Just a random, funny question - does the speeduino ecu have an obd2 style port for your laptop to connect to?

Does acceleration enrichment affect autotune?
Should it be disabled?

Im finding that auto tune will tune my idle and then it will start to jump around and also want to die at stop lights, so I lock out those cells from changing and this seems to help keep idle stable and no die out when rpms drop back down. 99 miata.

Good video, from what I have seen there is also Lambda Delay reference table seems like a good idea to also set that one (I think it could be possible looking at the logs, when e.g. DFCO kicks in vs RPM vs AFR), not maybe initially but to fine tune the autotuner, what do you think?

Could you recommend a good and safe timing map? I am currently tuning my 1.6 na miata with a larger t3 turbo on US 91 gas. It gets very hot where I live and I do not have access to 93 octane so I am worried that I’ll experience pre-detonation on basemaps. Also, I noticed that a popular basemap, Trubokitty, has what looks like different timing and afr maps depending on ECU. I know the table sizes are different but why would the tables be different? I am running a speedyefi if that matters. THANK YOU!

Would i be able to use this for a 650hp application? I want to use this to control the manifold port injectors i will be adding to my build. It will be dual injection ( direct and hopefully port injected)

what's the deal with above 100 VE values like 119 122, you need bigger injectors? shouldn't be 100 or 99 maximum volumetric efficiency?
