Dude your backyard Dyno setup in incredible. Thanks for the setup tips the way explain the settings are easy to follow. I’m not rocking a Miata but I can see some stuff carry over to my setup of a turbo 2.3 Ford. Keep doing the MS vids!!!
Watch the cells in your fuel map in those areas and make sure the AFR is reasonable through and leading up to the dip. You can also add some timing below idle setpoint to help is land more stable. Finally make sure your decel fuel cutoff isnt bringing the fuel back on too late
Have any advice for a high idle just installed ms2 in my 91 Miata ignition timing perfect afr reading a solid 14.7 for the most part my car wants to idle around 2,100 rpm and I can’t figure out how to get it down I did turn the valve on the throttle body to bring it down but it barely did anything I heard online you shouldn’t do that, that it has to be something with the new ecu any advice?
@@spankranchgarage you were correct my idle before once warmed up all the way was getting to about 2500 rpm I literally just unplugged my IAC and the car idles around 1000 rpm which is way better than what I was at now gonna try to self tune it a bit and get it down lower my afr stays around high 14s/15s so I’m happy so far thank you! One last question is it okay to leave my iac unplugged!?
Question - can we tune boost cells with EGO control on? I assume we can since, EGO only really happens under 100kpa, correct? I'm looking to start tuning my VE tables using Mega Log Viewer and Tuner Studio with either Analyze Live or VE analyze. Thanks!
Yes you sure can! I use it for tuning only then I limit EGO to low load situations. The thought is you don’t want a failing sensor influencing high load fuel and possibly damaging engine

Awesome, thank you!
So true about tuning on dyno is easier then all the little works . Great video!!!
Also interested in location. Or if you’d even be open to chatting about street tuning, boost control, etc. thank you.
Where are you located? I have a Miata I might want to bring to you for tuning. This video was super helpful.
The blue plug behind the right headlight seen in the vid when you used the timing light, is for the timing light or so I read at least.
You are correct!

How should would you approach fixing engine rpm dropping to 450-500 after a rev during netrual? I'm using a doctronic ecu and not much info on it :/

Sounds like an IAC configuration issue or it’s stuck open. Can you get the iac to make any influence on idle speed?

@@spankranchgarage awesome, are you using oem pcv valve?
You know you can set the pickup on the coil and that’s good enough to run a timing light
I don’t know it’s enough for my old light but I’ll have to give that a try thanks
bro where are u located i need help with my speeduino ecu on my miata, it runs poorly and wont start up immediately like this one 🥲
I dont do much public tuning anymore. But a lot of the tips in this video apply to speeduino as well as its function is pretty close to Megasquirt.
@@spankranchgarage i gave up and switched it out, thank you for the tips im just not capable of making it run smoothly and turn on smoothly
