I know I'm probably beating the dead horse with these question, but was hoping to get some unanswered questions. I already read the thread(s) several times.

Everyone is going to non-sequential for the obvious reasons, but does every aftermarket standalone or piggyback ecu support this mod? I was just wondering if anyone could tell me what kind of ecu they are using for this mod, as I too am debating this, but was wondering if the ecu was a factor.

Also I notice people selling non-sequential rx7 turbos all the time. But when you remove the turbos itself its still a damn sequential, am I right? Am I missing something because all your doing is rearranging the vacuuming as to make the turbos work together. So minus the vacuuming its still the same thing.

 

If u want to be safe, get an aftermarket ecu. That way, u can adjust anything and everything if u do come across some problems. However, I believe the stock ecu is enough to control non - seq twins. If u can't get an answer, there's only one way to find out.
Or u can get a piggyback system and control the stock ecu. But if I were you, i would get an aftermarket ecu.

 

What obvious reasons would those be? There are many of us who wouldn't dream of going non-sequential. As far as the so called advantages, on the track, you are in non-sequential mode pretty much the whole time anyway, regardless of the ecu you have.

A lot of people have run non-sequential on the stock or chipped ecus (pettit and m2). Ideally, you would run a stand-alone ecu (PFC) as non-sequential has different fuel/timing needs than the sequential setup.

Going FULL non-sequential involves procedures like welding the pre-control door open. You are thinking of the "poor mans" non-sequential.

 

TwinTurbo93 has a non sequential set up with Pettits unlimited ECU... He could probably help you too.

 

You can mod the pre-controll actuator to keep the door open, that way you can reverse the non-seq.
