Nice, I can't wait to find a cheap miata to practice tuning with.

The base map is an NA only one by choice. I can provide a turbo one as well, but those are slightly riskier as people just take them and run without making any changes, which is something you can get away with on an NA, but not so much on a boosted setup.

Yep, that needs the registered version of TunerStudio, then you get all those things.

Just in terms of missing features, if you can make a case for something being needed I'll add it. Simple as that. As long as it's something that's adding genuine value and not just handling 1 persons niche setup, then I want to make life as easy as possible for people.
Personally I've never had a problem getting good solid idle on any of the Miata engines I've done, but I can see why some people like dedicated curves for idle ignition etc rather than just using the advance table. AC Idle up was added a couple of months back (though requires a jumper wire on the existing PNP units that are out there). With the other models, I have a 64-pin NA8 board ready to go, I just need to find some cars to test on. NB8A ones are close, but again I need a test car. NB8B I haven't started on yet. I am interested in the NB1 one. I have a 99 someone threw intake header and exhaust on and have been tempted to put an ECU in it.... Having time to get it in and tested would be a few months out though since I am in the middle of renovating and moving. |
I've sucessfully installed and tuned 3 NA mx5's using Speeduino stand alone ECU's. The first one is a 1995 1.8 with an automatic transmission. The second mx5 is a 1993 1.6 with a Jackson Racing Supercharger and the third is a 1997 UK version with the 90 HP 1.6 motor. For what these MX5's have got the Speeduino is sufficient with the features it offers. I'm an experienced tuner and have tuned Honda's with B16's, B18's and K20's, EVO lancers with 1,100+ HP and Nissan R35 GTR's putting out 1,400+ HP with Motec's, DTA's, Link ECU's, AEM's, Haltech's. I recently got into tuning factory ECU's via reflashing through HP Tuners programming on a C6 Corvette with a twin turbo that so far has put out a very tame and streetable 800+ HP. I'll be putting the MX5's on the dyno soon to find out how much improvement we were able to achieve. So far the owners of the MX5's are more concerned with drivability and smoothness for the street.
IMHO every ECU has its own characteristics, quirks, and shortcuts which usually takes time to learn. Getting the best result in a reasonable time really depends on how familiar you are with the product, and how user-friendly the ECU is for you or for your tuner. For a novice tuner I'd recommend the Speeduino for the MX5. When installing and tuning any brand of ECU, some level of tech support from the manufacturer or distributor will be an invaluable help. Since I never had any experience with Speeduino before it was very helpful that Chris Cashion of Speedy EFI made himself very accessible by answering all my questions about their product, and yes they do have an aircon idle-up feature which their website gives instructions on what to do to activate said feature amongst many others. The price though is the clincher. $375 for a complete kit for the early NA MX5, while the ECU alone is only $260. The kit for the 1.8 NA MX5's is only $400 complete. For that price you'll still end up with enough funds to spend on other speed equipment for your MX5. It's worth a try. |

I'm running a na6 pnp speedyefi speeduino. It works great and is easy to tune for beginners. I use ts, an aem wideband, a gm sensor, a bmw vtps and the pnp adapters. My car definitely gained some butt dyno hp. its worth what they ask for. if you're not looking to make 350+ hp, I don't see why you wouldn't want to use this unit.

Speeduino ffirst start
Hi guys having trouble with a speeduino ecu have done the initial setup and plumbed the vacuum line to the intake manifold I am running an innovate mtx-l wideband and I have a vtps installed, when attempting first start i have crank but it just wont start so i need to check my timing ? Sorry might be a noob question but I'm new the whole ecu tuning thing tia

attach your tune (MSQ) and a data log while cranking (MSL) :). by the way the speeduino forum is the right place to get help on this

Whenever it comes to things like "why wouldn't you get the best (most expensive) option", I always ask "what are their goals". I run a MS3Pro in my NB2, and frankly I don't think I'll ever take advantage of its full feature set. However part of my goals for the car was to make it reliable, and easy to find support for.
I had a 1990 Celica with a 4AFE engine. It was a 500$ car, and I figured a ~200$ ECU just to mess around with was perfect. I built the adapter harness for it, cut some teeth off the dizzy's wheels, swapped in a Volvo TPS, wideband and bam I had a lot of fun. It was terribly unreliable, and since no one else on the speeduino forum had run my motor much with a Speeduino, I was pretty much on my own. But as my goals were just to have some fun and try to eek out a bit more power, it was perfect. I think that for the lower-end builds a Speeduino is perfect. If it can get the motor running properly, safely its just up to the owner to make sure that they stay within their ECUs limits. Why does no one talk about RusEFI anymore? |

Is it simply taking a while to start, or is it spitting, sputtering and doing starter kickback? Spitting and sputtering: First, double check your ignition timing on the crank vs the spark advance gauge in tunerstudio. Then, try turning your trigger filter from weak, to medium, and then to aggressive. Just slow to start: Its likely too much or too little fuel while cranking, try using flood clear mode, and if it starts easy with flood clear mode, reduce te amount of fuel while cranking. If it won't start at all with th throttle wide open, then add 20% more fuel and try again. |

On the speeduino there is no closed loop initial targets for the iacv. There are no idle ve, idle advance, or rpm timing correction to add or retard timing to give a more stable idle. I don't even see an ac idle up feature. Those are all features that are important to me. It does however offer vvt control so for that feature alone I would consider it over a ms2 for a track car that would use a vvt motor. But for a car that keeps ac or that goes on the streets it still seems like the ms3 would be better in every way besides price. I just bought the no2c version which has only two injector and ignition channels as well as the vvt boost control, auto tune etc.... Why only 2 channel? Because that's what the factory hardware is... 😁 |
