Hello,
a bit of story so please bare with me.
My 92 Audi 80 originally had 2.3L NG 5-cyl engine with Bosch K-Jetronic CIS injection, tried EFI using MS1 clone based on Atmega 328 (fuel only), batched injection, it worked and revved, but somehow rough on idle, see pictures attached.
But due to a series of unfortunate events I had to put this project a side, now, I hope it's time to finish it as planned.
My goal is to build speeduino to function the basics, sequential injection, COP ignition rather than stock dizzy if applicable, closed loop idle control, warm-up enrichment, load compensation (A/C, electric fans, tranny load, lights, heaters, etc), anything else is considered a non-useful since the engine has no EGR, no VVT, no turbo, ...,
I have Mega2560, STM32F103C8T6 (aka black bill), ESP32, and Atmega 32A, but not Teensy, however, since space is premium, I do prefer to use the smallest board to keep the foot print as little as possible, if the black bill as example needs I2C flash then I have several chips as well.
I've searched this forum a lot but here the main focus is on the mega2560 and Teensy, anyone has tried the other boards I mentioned ?, could you kindly share your experience and results ?
Thanks.
