Setting up the bins on the X and Y axis to match your car’s operating range is something I feel is super important. The voltage correction curve is far more important but even that need not be perfect to get you running well enough to tune. Running 1ms for high impedance and 0.7ms for low impedance works most of the time. 14 years of tuning experience with Megasquirt ECUs says not so much unless you are running really large fuel injectors ( 1200 cc/min or bigger ). Conventional wisdom and most tuners say that you absolutely, positively HAVE to have accurate dead time values. Fuel Settings are next.įuel Injector deadtime/PWM: I’m a heretic here. I also check the rev limiter settings and if it’s an MS3PRO PNP, the cooling fan on and off temperatures to make sure they are what I want ( I live in Florida so I’m often lowering the on and off values ). This is where you set required fuel which is determined by fuel injector size, so unless you are running stock fuel injectors you will need to alter the required fuel. It’s like playing darts drunk, dizzy and blindfolded! Miata and forced induction guys you probably have a GM air temp sensor installed somewhere so be sure to calibrate air temp too. Don’t waste your time trying to tune without one. TPS calibration should be checked as should battery voltage and AFR table ( wideband O2 sensor ). PnPs generally have the current release firmware and the correct calibrations loaded for coolant and air temp sensors.

This is where you update firmware and calibrate sensors. The first thing to look at is the tools menu…. MSPNP2 users, PLEASE spend the $60 it’s well worth it.

Get the registered version! MS3Pro PNP ECUs come with a coupon to upgrade to the registered version for free so no excuse for you guys. The free Lite version is on the USB drive that came with your ECU. You’ll be using TunerStudio MS software to make the modifications to the start up map. The details of that are a whole separate topic. Is it a drag car, track day toy, endurance racer, dirt track or whatever? You need to know that because HOW you (or your tuner) actually sets up the final tune is dependent on it’s primary purpose. Whenever I start a new project, be it my own or a customer’s, the very first thing I need to know is the primary use of the car. However the start up maps are for pretty specific parts combinations and chances are it’s not exactly like YOUR car.
They all come with some pretty good installation instructions and decent start up maps.
Part 1: Plug and Play ECU modelsĭIYAutoTune sells a number of MS2 Plug and Play ECUs (MSPNP Gen2) and MS3 based Plug and Play (PnP) ECUs (MS3Pro PNP aka MSPNP Pro).Į30 BMWs and E36 BMWs, Fox Body Mustangs, Miatas, Nissan 240SX are just a few of the popular cars that have an available MSPNP.
“What do I do now?” That’s what we are going to discuss. So you just got your MegaSquirt installed and it’s time to get it running and tuned.īut wait, the map that is on the ECU doesn’t perfectly match your car just yet. If you need installation or EFI tuning help and you can get your car to Florida, he’s a great guy to work with!
