The APEXi PowerFC is a standalone ECM.  This one is specific for the 1ZZ-FE.  It hooks up to the factory wire harnesses directly and I currently have a harness extension to give a bit more room and provide access to the ECM signals.  It is mounted to the rear of the compartment behind the seats essentially in front of the stock ECM.  You just unplug the harness and plug it into either ECM depending on your setup.  The PowerFC gives you complete control over engine timing, spark, fuel, narrow band O2, knock, MAF, etc. for tuning and driving.  The map currently loaded is from the dyno tune at Boost Logic by Justin Nenni from Tuning Concepts. 

The tune is set for good street driving but if you know what you are doing, you can tweak it to obtain desired power for additional mods. 

Before I started any of this project, I checked the compression to ensure the engine was healthy.  I then ran on the dyno at Colvin Automotive in stock NA configuration.  The rwhp matched the expected output from the factory so I determined the engine wasn't sick and began the boosting!

Here is a video of the stock dyno run.

I started off doing email tunes with Web3.0 but both of us became too busy to drive around, sift through logs, tweak, repeat.  Here is a video of the FC Edit Software which uses the FC DataLogit that allows you to connect your APEXi PFC to your laptop using a serial port.  This makes tuning way easier since you can see all of the map on one screen and easily tweak values as needed.  The discerning eye will notice that most of the map looks unused.  This is because the MAF is from a Toyota Supra Turbo and is capable of substantially more airflow than what the 1.8L can breathe.  Web3.0 chose this MAF because it was the most stable and tunable of all the ones he and other forum members had worked with.  For you, this means you have plenty of room to increase the flowrate without having to change the setup.  See the "Supercharger" page for more details.

Eventually, I decided to get a proper dyno tune from one of the best in the industry.  He normally handles the 1000+ hp Supras, Lambo's, Ferrari's, etc. but was very familiar with the APEXi PFC and quickly discerned my setup.

Here is a video of one of the tuning runs at Boost Logic.  On this run, the exhaust O2 blew out of the tailpipe because it wasn't secured very well.  Don't mind that, we got it fixed for the other runs, especially the final runs.

Here are the results.  I went from about 122 rwhp stock to 196 rwhp boosted.  The graph below isn't the final tune run and looks a little rough but I didn't have the final logs so this gives you the general idea.  It got up to 196 and much smoother!  My goal was 200 to 220 and I'm confident that a high flow cat and exhaust will easily get you there.  The max boost came in at 10psi and that too can increase with the change of a pulley on the Rotrex.  I wouldn't recommend going beyond 225-250 with stock internals, though.  You would also need to consider changing the fuel pump to a return type with a regulator and high flow rail.  Those aren't terribly expensive and will most likely be needed to go beyond 225 on 1ZZ engines.
