Well now that I can ask this this is something I've seriously wondered about. Would it be possible to run the 13b-re(w) off the rx8 ecu if you had say a custom intake manifold made with provisions for all the sensors,tubes,ect.? And then copied the 13b factory fuel/air/timing to make it run like it would off its regular ecu using something like an accesport? I don't own one yet it's just a theory I've been thinking about trying after my winter cars finished

Not well.....the Renesis computer has things in the tune that are specific to the intake tract and staging that won't mesh up. There are also a lot of things the Renesis computer won't let you adjust and the tune is based on the Ve of the engine...that is very different from the REW engine


For the amount of work it will take...and the likely fail...it isn't worth the work

what your saying sounds logical but I may end up trying it anyways just for testing purposes. Maybe on a cheaper 2 rotor tho. Worst think that could happen is I blow up a na 13b and have it sitting on the side for one of my other crazy ideas or until I move somewhere e-check free

pair it with an Adaptronic piggyback and it's no problem, most of your proposed mods go away

you haven't thought it through otherwise IMO, but understandable since you have zero experience with an RX8 application

you won't be the first to say I'm gonna buy one and show you all and then to have either failed completely or never be heard from again

the only reason to do it that way is to save money, which is not only uninformed, short sighted, etc., but also an obvious indicator that you are already in over your head for even considering the idea

I never said I was trying to prove anyone wrong. I haven't been able to find any info on anyone else trying this so I figured why not give it a shot. And also I wanted to try it to see if it may Beable to pass echeck.

But you're saying why not give it a shot without any comprehension of what it entails.

It's like saying you want to jump off a 30 story building rather than take the elevator. People are saying don't do it, but then you say why not give it a shot?

It won't work, you don't understand enough to realize why.

I'm going to assume you think I would try it with out researching what the differences are in the tune and everything else. No offense cause Ik most people jump the gun and call it quits when they can't get it to work but I've got a little more common sense than that

In theory sure, In practical application better methods exist. One could swap the front cover and everything attached to it and fool all the intake runner stuff. It just makes more sense to run the adaptronic like Team said. Thinking about all the alterations one would have to make and the time spent only to make the stock MAF and Ecu work in your favor is irrational when much better methods exist.

Based on my own understanding of what the job entails, it sure doesn't seem to come across that way at all ....

not trying to be condescending, in my life I've had my own share of grandious ideas that I look back on now in total 'wtf was I thinking?!?' disbelief ...

I think it could work - ap gives you access to the full VE table, although i think mazdaedit would be the way to go.

Xsessive makes a lim for the 13b that fits 4 injectors instead of 2.

You'd have to probably ditch vdi and ssv, apv, but i don't see why it souldn't run any worse than adaptronic if you are still using rx8 tb.

Another option of course is to make an adapter plate for the manifold - apv may have to be left fully open most likely. ..

The only reason why I said accesport is because I know absolutely nothing about any other tuning software for the rx8 I'll have to look into that for my current engine

well I got a 4 port running on a 6 port ecu using the AP, so you should be able to get the 13b running...




This would be a lot more likely to work than trying it with an REW
