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!
Miata ecu tuning how to#
He chose to go with TDR and the EcuTek interface.Jeff has been a long time user, reseller, installer, and tuner of our products for many, many years now and has offered up some of his thoughts and insights on how to help you get the most out of your car and engine management system. I did not include the Sniper interface box as I was still using it to dial in my new Begi turbo setup, so the customer had to source the tuning on his own. I recently sold and installed my previously loved Cosworth supercharger. It always seemed to be an interim tune that the customer could drive safely but if they wanted refinement (and power) they’d have to spend more time on the tune themselves. What made the above process most frustrating was that when the customer picked up the car I was never really happy with how the car ran. It is amazing how time consuming driving, logging, emailing the log along with driving impressions, downloading a new tune, loading it onto the interface box, flashing the ECU and repeating the process at least a half dozen times (usually it takes at least a dozen times) can be. The tuning part of the installation has always been the part that I have dreaded the most. This would include my car (the Blue Meany) as well as numerous customer cars that have gone forced induction and had me do the installation. Over the years I have flashed an NC MX-5 probably 200 times.
