It's a reply to the post above mine about the parts required...

Seems like significantly more effort, which is why I posted the Kpro link.

If you're keeping the stock ecu, I'd just keep the evap in place so you don't have to vent the tank.
Yes it does. Puddy mod and a few other people specfically sell EGR block off plates. On AP1's they can be found on the rear of the intake manifold closest to the fire wall

Id go AEM and ditch the Kpro idea. Im running no emissions. No EGR, no EVAP no air pump, no cat.

Also if you're primary use of the car is on track you can get a lower thermostat and actually set the fans to come on at lower temps among other things that can help you keep things in check.

Yes that was my point. Doesn't make sense to try and run flashpro

That's a blocking plate for the air injection system whos only purpose is to pump extra air into the exhaust to heat up the catalytic converter at startup. It has zero impact on performance. Anyone calling it an EGR block off is either misinformed or trying to sell something to the misinformed.

You need a 2006+ drive by wire conversion. Cam and crank sensors/trigger wheels. Valve cover. Coil packs. Intake manifold including fuel injectors. throttle body including throttle cable. Engine wiring harness. VSA sensors. Conversion from return fuel system to returnless. Etc etc etc
Sorry for my incorrectness in calling it "ap2" conversion. Seemed like everyone knew what I was talking about based on the first post, but whatever. DBW isn't a huge problem, since I'll be running an aftermarket pedal box anyway that accepts a DBW Throttle pedal position/angle sensor. I guess it's a problem if the throttle body isn't a simple swap over, cause then I'd for sure need the 2006+ intake manifold. Are the injectors actually different or is it just wiring? Could the AP1 injectors work by modifying duty cycle with Flashpro? Do I completely miss how Flashpro works? I'm under the impression that it allows the flashing of a map similar to a Cobb system. I see the V/C would need to be different for the cam and crank sensors and stuff, but are the coil packs different? Assuming the coil packs and injectors could be used, why would I need an engine harness aside from the connectors at the ECM. This is probably me being stupid but what would running a return fuel system vs a returnless fuel system mean to the ECU operation? If I'm not running VSA do I still need all the sensors? VSA can't be disabled with flashpro?

Again, I'm used to K-pro where that stuff can be turned on and off.

First, yes it does as in it goes into limp mode, or it has "EGR". I know the valve you're talking about on the back of the intake manifold that works with the air pump, that's what I meant also.

Second, you missed the part where I need to use a factory ECU. Can be any model year but must be the same model (S2000 to S2000, Civic to Civic, RSX to RSX, etc). I'll also be running a manual fan switch probably with no thermostat, just a restrictor. Things don't work the same on a dirt track as they do on a road course.

I think maybe I've asked the wrong question, or perhaps people are focusing too much on the other questions.

Can an AP1 ECU run properly at WOT with all emissions devices missing? (No limp mode or stupid map).

Start here and watch the whole series. (Click on the series after the preview.) Pay attention to the performance they achieve -- and money they spend.

your're right. The air injection valve looks like an egr they are both diaphragm valves. I apologize
