What do you need to do to keep from running lean with the single turbo? Is it as simple as altering the fuel map? What have some of you done? Or did you just leave it to a proffesional?

 

What turbo?



The turbo size is what most of us will base our info on. Plus what type of boost you want to run, also if your ported (thinking not).



Professional is better, but it all depends on what we are talking about in more detail.

 

You need at least an aftermarket ECU. If you want to add all the bolt ons and run higher boost you need a bigger fuel pump and injectors. You can get away with less fuel with the smaller turbo's (apexi, to4e w/ .84), but will still need an ECU and some tuning will be involved.

 

Your three variables: FUEL, SPARK, AIR.



Change the stock setup and you will have to adjust the relationship between the variables. This is done by tuning.



Have it done by someone who is experienced with references. To accomplish the tuning you will need a setup that can accept changes...like an aftermarket ECU.



Doing a single turbo on a stock engine...why? Why do it halfway? Costs around $3K just for the single setup. Not to mention the ancillary cost of supporting fuel, ignition, etc. So why not get the enging rebuilt, have better water seals put in, etc.? Budget around 300-500 for tuning a single. Do it right, do it once, the shortcut is doing it the right way.



(Falls off of soapbox)

 

So what's a good aftermarket ECU to use? Will just any decent one work?

 

An ECU that you have alot of local support for. Got a buddy who is a MicroTech wiz? You got the answer. Got a neighbor who runs Apexi PFC? Hello, neighbor! Guy named Kan lives down the street from you? Goto Haltech, do not pass Pluto, if you could. Check the regional sections and hook-up with the other addicted Rx-7 owners. Word.

 

your a wierddd guy........

 

The problem lies in that I have the sole RX-7 in my area. Yes it turns heads, but I don't have anybody to talk to in regards to it. That's why I love these forum sites.

 

You want the PFC then for Your single turbo. You then need a wide band setup and the datalogit from RP, with these You will be able to tune it yourself and get a decent base map to start from the Datalogit group. I have the tech edge wide band and it works great.

Stay on the box. People need to hear and follow this code of law.



If they did, then we wouldn't hear as many "Rotaries are $h*t!" comments.



Keep the mixture correct! The only thing that could kill you then is if something throws it off (broken hose, wg, etc)...But thats why you have gauges to watch if anything falls out of place...and the moment it does...don't drive the car..and fix whatever's messing up.
