I'm working on manage my NB Miata with the Speeduino ECU. I'm working on a parallel install so my Stock ECU manages the alternator, idle valve, a/c, fan, etc while the speeduino only manages injection and ignition. This is my workload thread if you want to see more about the Hardware install
Since I manage ignition cranking is very hard for the engine. Sometimes after several long attempts I can start it and the engine works and is drivable, but feels more lazy that when the ignition is managed by the stock ECU. After some PSIG suggestions I've been checking on different base maps for the VVT engine the voltage corrections for injectors, dwell, cranking etc.
In general terms the "default" speeduino map has very low dwell duration and low corrections compared with ME221 maps or MSPNP maps.
So guys, Can you share your dwell and corrections to compare with mines? These are the ones that I think the engine will need after yesterday source. Unfortunately I have not been able to work on the car yet and load the new tune to the Speeduino to see If it cranks better.
