Can you have a ported motor, and single turbo set up and run it with stock computer? Also is their a difference between a 1993 engine harness and a 1994?

 

no

 

no

 

Absolutely not.

 

Yes you can. As long as you have upgraded fuel system additiinal injectors an additional injector controller setup correctly and fuel cut defender. I'm sure i'll get flamed but it's true you can.

Uh huh...and let's see what kind of performance you get (compared to a properly set up ECU and fuel system) and how long the engine lasts....

 

Thanks for the info.. Their goes my idea to start the car with a stock computer. I'll just wait for my power FC

 

I dont belive so from what I have read. Need to do look into it some more.

 

um, right if your an idiot u can do that. What about timing adjustments.

 

though porting has some to do with fuel as you're taking in more air, the timing is the more important ingredient that will surely fail your motor

piggy backs aren't the answer to an RX-7

 

Don't even think about it!

 

I wouldn't bet my 13B on that.

 

The timing entirely depend on how much boost you are running if you are not much above stock boost the timing is fine and will retard as normal when it needs to.
If you going to be running say above 1.1 bar boost then you would need a aftermarket ecu that can cope with timing better. The Guy's point was not going into particulars regarding boost or anything else he was just simply asking can he run a stock ecu with a single turbo
and the answer is yes. No said it was ideal or better than a apexi or anything like that

POSSIBLE?...yes....
EFFECTIVE?...no......

 

Yes, hook it right up to the stock ECU and fire it right up.
Make sure to floor it as soon as you get it one the road.
You really wanna BREAK it in don't you?

 

The way KDR explained it to me is, you need to retard the ignition on a ported motor to take advantage of the larger intake and exhaust ports. I'm not aware of anyone running a street or race ported motor with a stock ECU. I wouldn't want to be the first one to try it either

 

I run a bridgeported single turbo fd with standard ecu that's the reason why I say that the other chap could. I had just run a new engine in with the standard ecu and still have it on there with a little over 2,000 miles on it now. I will be having a microtech ecu fitted eventually. I am currently only running .85 bar of boost the car pulls very very strong. I have done numerous runs at wot while setting up the fueling. When i'm ready to run + 1.1 bar off boost I will fit my microtech and get it tuned
until then while running .85 bar of boost the stock ecu can cope and does cope just fine. When i'm ready to hit approx 500rwhp I am aware the stock ecu is no way near capable and I'll have a microtech fitted. I will let you guy's know if I blow my engine beforehand and will accept the (told you so's) like a man.

Well, here's the deal:

We realize that it's entirely possible to get a ported/single turbo motor to run with a stock ECU-- with whatever fuel mods you've done. However, when someone asks "can you have a ported motor and single turbo setup, and run it with the stock computer", if someone says "yes, you can", then some unfortunate person will think "oh great, then I don't have to spend the money for a standalone." They'll run out and have someplace that doesn't know WTF they're doing install the stuff, he'll run out to the first straight he sees, guns it through the gears and "poof". They won't know that you meant that you can just make the engine run, not run it all the time with that setup.

You have to be careful how you word posts and responses, because it's way too easy for someone to take it the wrong way.

Oh yeah, almost forgot: I'm sure that you have access to better pump fuel than the crap that we get here in the U.S.

 

I ran a race ported motor with intake, and full exhaust on a stock ecu. I have my turbo setup non-sequential so I get no boost spikes. Boost drops to about 8 psi near redline. I threw in a pettit ecu and ran the same time and mph. I can't wait to take advantage of my port when I throw the haltech in. Yes you can run a ported motor with a stock ecu.

 

Point taken Kento,

I could of worded it better. We have 98 octane fuel here. I think what you have is basically the same I have been led to believe that they way your octane is calculated different but I don't believe there is that much difference between the two fuels though but maybe i'm wrong. For interest I will post dyno figures of my bridgeport with stock ecu at approx .9 bar and dyno figures with the microtech.I will do a few runs with the microtech one of the run's at .9bar to compare the difference with the stock ecu.

Maybe so in your case, but the original question was can you have a ported motor and single turbo setup and run it with the stock ECU.

Plus, think about your post: people are going to think that they can run a race port with intake/full exhaust on a stock ECU, and not blow up their motor due to boost creep.

 

how about this...

you can put it all in... and break the motor in with the stock ecu... for obvious reasons.. dont floor it very much

 

Thanks guys I will let you know how it goes

 

I wouldn't do it...

About the octane thing, I'm sure their rating is different...
Ours is like (mon + ron) / 2. While other countries fuel is rated with just the one rating, not the average of the two.
