One can spend a lot of time getting these things to where the car starts and runs like a stock Miata under all conditions… until you hit the gas.Īah the age old debate… it really depends on what you are trying to accomplish. Power tuning is relatively easy on a Megasquirt turns out nailing all the little details for every day driveability is a much greater challenge.
Closed-loop idle, acceleration enrichments, electrical loads, heat-soaked starting, EGO compensations, air conditioning idle up, etc., all need to be calibrated for our own specific vehicle. Things like cranking and cold starts, after-start enrichments and warmup can take time because we really only get one or two shots at most per day. With a standalone ECU, it’s just us working on one specific car, probably when we have a few extra hours to mess around with it.īecause of this, nailing down all the little details that make everyday drivability a pleasure can be a much greater challenge. Car manufacturers spend thousands of hours and millions of dollars developing calibrations that will run on every version of that car in every conceivable condition we don’t have the advantage of starting with a factory tune. Remote tuning a standalone is a lot more difficult than reflashing a factory computer, and reflashing the OEM ECU on a NA/NB Miata is not even an option. Know that sometimes we uncover hidden issues with cars we are happy to assist with figuring these problems out, but diagnostic work is extra!.Though not necessary, 1.6 cars benefit greatly from installing a variable throttle position sensor.Your initial calibrations must be set properly you will be provided an initial calibration worksheet which has detailed instructions before we begin.Values in TunerStudio match what is shown on your WBo2 gauge. A wideband o2 sensor, hooked up properly and communicating with the Megasquirt.Enthusiasm, willingness to learn, and the ability to follow instructions precisely!.
