Your missing the point here...once a turbo gets out of it's effeciency range, it doesn't matter what FMIC you put on it, it'll STILL be too hot.



Also, you want the commander. Trust me. Ask ANYBODY that has a PFC...guarantee you that even if they have the datalogit...they'd still HIGHLY RECOMMEND getting the commander.

No i'm not missing the point i dont plan on ever running 17 psi. And i cant afford the commander and the datalogit at this point so i have to pick on and then i can get one or the other in a few months when i have the money. I just bought a new engine and rebuilt my turbo dont have the money for both right now. So i think the datalogit is the better of the 2 for now. It's not liek i'll be changing things all the time i just want to adjust for the 1600 CC and then set my boost to 15 psi.

Then why not slow down and WAIT until you can afford both.

Is it true you dont use the old splash gaurds and o-rings from the origanal secondary injectors?

Ok quick solution. Buy the commander. Get with someone that has Dataloggit to set the profile for your car and fine tune it later. What people are trying to tell you is to pay attention. They are trying to help you not to make the mistakes they might have or know will not work. With the amount of memebers on this board and other RX-7 forums I am sure there is someone in your area that would love nothing more than to stop by and give you a hand in this adventure. Having a new rebuild on your turbo, and your engine I am sure you want it all right when you decide to get on it. You posted all the information you were trying to do at once. These guys saw red flags flying, they are just trying to help. Take this as a blessing and not a hit on your ego. If more than 2 people are trying to tell you something is wrong, you might want to sit back and rethink what you are doing.

You do not use the splash guards again or the O-ring....You have to remove them in order to make the injectors sit right. Also you need to cut a small piece of 5/8 inch hose and put it on the injectors to make sure it seals good. Just stick it on the fuel rail and see how much still sticks out and then cut a piece of hose a little bigger then that length. It's pretty straightforward, except you have to buy different injector clips, at least for the 1600's you do.

seems like your rushing it. SAVE YOUR MONEY. You want both...not one or the other.

Sorry if i came off as a little pissed in my last post. I just had my wisdom teeth pulled on friday and these meds are reallly messin with me. But any way's i see where you are coming from. I could just save up for both, but your saying that if i can find someone with the datalogit to go ahead and get the commander? Also what are the red flags the last thing i need is to blow up this engine. I didnt think i was harming the engine by putting 1600 CC inj on it. Other than more boost, more power, more wear.

The red flag I noticed was when you got defensive about someone telling you that you should not run 17psi on that turbo. Understanding the efficiency of a turbo is ket to its power output. Having a FMIC does not mean you will automatically take all of that heated air down to a good power making level. Once the FMIC becomes heatsoaked from the input air from the turbo you will begin to lose power. I wish I could remember the formula off the top of my head, but its close to 10° in temp drop = 1 hp gained. And depending on the efficiency of your FMIC, you may not be able to make the required temp drop running the boost level up that high. Although in the later post you said you would not run above 15 psi, the thought was there that you may take away the gains you would make at 17psi because of the heat. Hope this makes sense

Right i understand i cant run 17 psi and that any thing above 15 psi will cause to much heat now. But there is no prob in running the 1600 CC @ 15 psi right.
