Well guys, im new here but i have some question about a problem we have with a Rx8.

We got a Rx8 with Greddy Turbo Kit w/ Emannage Ultimate, we r lokking for some upgrades and we install 7500cc injectors upgrading the secundary stock injectors. Now, the e mannage comes with a protected by password map and we clear that map and using the same map without the password to can modify the fuel maps. the problems its, witout modify the map, the car start and goes off. when we check everything, we found that the cars dont have fuel pressure when the car its on. We modified the fuel map to get the car in idle but we have the same problem. Now i read that the fuel pressure its controlled by the main ecu, anyone has that kind of problems?


I will apreciate your opinnion about this. Sorry if my english its wrong, this isnt my first language. Thanks

Emanage normally only functions in Open Loop, Idle and low load areas should be running of the stock PCM. Are you running Emanage as a stand alone? I need more info.

If you are adding injectors, make sure they are the P2 aka Sub Injectors... these are severed in EMU (PCM does not use them), so you can control them 100%.

Yup, im running emanage like a stand alone, but the problems comes after the injectors installed and im monitoring the fuel pressure with a greddy electrical fuel pressure and its mark 0 of pressure. To stay the car in idle, we maximize the primary injectors because the base map, cant stay in idle

You have some wiring issues I would think.

The stock pump runs at 2 speeds...depending on load..but it would seem you have bigger problems than that

Well, the car had the EMS installed already before the injectors upgrade and the car runs for the last year with it
