First, we need to install a device called "Check valves" to trick the MAP sensor! The MAP sensor reads atmospheric pressure in the intake manifold. If it sees boost, it will send it to the ECU and the ECU will throw a check engine light! Stock ECU does not like boost! It was never programmed to see boost.

So, to trick it, we will use a system called "Check Valves". All it does is, it bleeds off boost from the MAP sensor. If you have a check valve in your hand, try blowing through it, it blows through easily! Now try sucking on it, air will not suck in! So when your car is boosting, the air will go through these valves into the atmosphere and trick the MAP sensor.



To remove the MAP sensor first locate it. It is RIGHT on top of the throttle body. If you can't find it, ask someone or get a Honda manual. It has two screws. Unscrew it and pull it off from the throttle body.

Construct the MAP sensor check valve system just like in the picture. Now, the end with "T", hammer that into the hole thats on the throttle body where you removed the MAP sensor. The other end, connect it to the MAP sensor nipple. You can zip tie the MAP sensor or just let it hang. But if you have some money laying around, you can buy a MISSING MAP LINK. They cost $65 on average and work just like the check valves but give the car a more CLEANER look. However, they are costly.



First, find a place to position the FMU. You can mount it on the firewall. Use a drill bit and drill 2 holes and screw it to the firewall.

The FMU is quite simple. The top part of it, connect it to a vacuum source. One good vacuum source is from the stock fuel pressure regulator (Which is outlined in GREEN) Cut the vacuum line coming off of that in half. Then connect a brass or plastic "T" to it. Now connect a vacuum hose to that and connect the other end of it to the top of the FMU. The side port on the FMU is the "inlet" and the bottom port is the "outlet".

You will notice a rubber fuel line coming out from the stock fuel pressure regulator (FPR). Now, before we disconnect this line, we need to relieve gas pressure from the system. Open up the gas cap. Now, you will need to buy new fuel lines. They don't cost that much anyways. Probably like $5. You will need 6 feet of it, 3/18.

Remove the rubber fuel line from the stock fuel pressure regulator and the other end of it will go down and connect to a niple thing that goes back into the fuel tank. Pull off the other end of it. Now, with the new fuel line, cut it in half (3 feet). Connect one end of it to the stock fuel pressure regulator and the other end to the SIDE port (inlet) port of the FMU. This new line is outlined in BLUE in the picture!

Then with the other 3 feet of fuel line (Outlined in RED), connect one end to the BOTTOM port (outlet) of the FMU and connect the other end to that nipple all the way down there, where you removed the old one! Easy as that!

Clamp the lines and make sure they are tight. Turn the car on and make sure there are no fuel leaks. If there are, make sure the lines are clamped tight!



Now, if you decide to use an intercooler with your setup, we have to start off with the intercooler first! Now, you will need to find an intercooler that will fit underneath the bumper beam and clear the ground. And make sure the "in" and "out" ports on the intercooler are on the SIDES! Not on the top or bottom. Spearco, Greddy, Apexi' all make intercoolers that use side ports.

Once you have the intercooler, place it underneath the bumper beam. Now you will have to figure out how to keep it there so it doesn't move. The EASIEST method would be to take it to a welding shop and just let them weld the top part of the intercooler to the bumper beam.

However, if you do not want to do that, then buy two L brackets from your local Home Depot. About 2 inch long. Then get it welded to the side of the intercooler. Then the top part of the L bracket, drill a hole and screw it to the bottom part of the bumper beam.

Some intercoolers have lips on the side of the intercooler to bolt to the bumper beam. So you just drill holes on the bumper beam and bolt the intercooler on with 2 bolts/nuts.
