Why dont people implement FPGA/PLDs for handling engine cycles and what not? overkill? They do. Adaptonic uses an FPGA, at least in the 1280 model The Pectel ECUs do fuel/spark/crank, all time the critical stuff control on an FPGA The motec M1 series use an FPGA for logging.... 2000 channels at 100...

I found an error in the injector stuff and added something for the simulation use.

Here is my accel/decel mixture correction model separate from the main model. There is a complete write-up on the function in the tuning manual I posted. Maybe over complicated but it should work and can not become unstable like an x-tau try approach often can.

Forgot to get to the main point. The software is free and the simulation ability is pretty good. You can create the ECU model then you can create a separate model by assigning the items to "plant". This is what I have in the model I posted so it's simulating the ECU and simulating an engin...

Engine lab designed the current line of AEM ECUs and they run on the enginelab firmware with a version of EL console modified to remove the ability to view or edit the model (algorithms). AEM had an exclusive license for automotive retail but that has now expired and enginelab is making a very slow ...

Not sure if this is of any interest to anyone other than me but I'll share anyway :) Attached are: Tuning manual - a word doc that explains how to use most of the furntions and kind of how they work Engine_Sim_12_06_V97 - ECU code and engfine simulator write in EL Concole, free dowload Engine_Sim_12...
