Hey everyone,
So I am extremely new to ECUs especially Speeduino, and I am in a bit of a pickle. I am currently working on a project on my 1994 Miata with a 1.8 naturally aspirated build, with a few bolt ons such and the NB purple injectors and the Skunk2 throttle body and intake. I ran my stock ECU for a while but with the added intake flow and throttle body size, I was forced down the path of tuning because the only way I was able to sort of run my car was to boost up the fuel pressure. I say "sort of" because my car constantly ran super rich and there was a certain spot in the throttle where the car would lean out.
Anyways after that background information, I am experiencing a problem with getting my car to run on the base map I have downloaded for the car. I can get the car to start sometimes without having to keep my foot on the throttle, but if I dont apply the throttle it stumbles to idle and then just dies. I have tried closed and open loop idle settings, preferably I would like to tune closed loop, but the car is still struggling. I have a datalog of me trying to get the car to run as well as the current tune settings I am running linked below. I f someone has any ideas as to what is happening seeing as I am new to the tuning scene, it would be much appreciated.
