25de plus t auto ecu

[R NIKCUF B]

Hey there,

 

So I'm looking at Plus T my partners 25DE R33, now I'm ready to go I just don't know what ecu to run for the conversion. I haven't been able to find anything to do with plus T conversions with autos so I'm just wondering if anyone can shed some light on this for me.

I'm doing similar with rb20 now. Running a haltech piggyback to retain factory ECU for gearbox . 

Don't let anyone talk you out of it if you can do the work yourself.

You will have to piggyback something (as above haltech ecu will work) or put in a custom auto transmission ECU (they do exist!).

Putting in a manual is better in every aspect though, including labor and yes, teaching someone to drive manual is easier than doing this conversion and a lot less hassle.

So the main reason you want a chipped ecu is so you can get it tuned to prevent Detting right?  Not really after massive power, just going to set it at 5 psi enough so it's not a complete slug in her words. I know it would be so much easier if it was manual but she's not budging about not learning manual which is a pain in the ass.

Making her budge is easier, and it is BY FAR making it the easiest way make it not a complete slug.

Or if you must absolutely have an auto and your partner is literally missing a leg, buy another car.

Now that that's safely ignored, you need an ECU to provide proper fuelling for the turbo motor as opposed to the N/A one. 5psi is signifigant difference. You need to control differences in airflow and injectors will behave differently, and you need an ECU to be able to tell the motor what to do, it's not just about preventing detting.

I don't know enough about R33 ECU's to know if you can just get a stock turbo auto ECU and plug the fkin thing in, or even better, buying a turbo auto car.

Any steps down this path will, 100%, always, unavoidably cost considerably more than what you paid for the current car, OR flat out just buying a turbo auto R33.
