i've done a turbo conversation on a rb25de neo

I've got a rb25det manual ecu (didnt know it was manual) and my car is automatic so it doesnt work with it. and i've also dont have the wiring harness for the rb25det

can i send the manual ecu away to nistune get it chipped and get it back and will it work with the car? (get it tuned etc)

No it won't, read my PM to you, and GTSBoy is quite right a manual ECU is not built to communicate with an auto trans because at the lowest level of thinking THAT WOULD BE STUPID

do i need the rb25det neo ecu AUTO?

No. I have already told you that. The 25DET auto ECU has the TCU inside it. Your transmission is currently wired up to a completely separate TCU on the other side of the car. Putting another TCU into the car isn't going to help anything, and the DET ECU does not expect to talk to a TCU that is outside the ECU, so there's little that you can do.

You could try - but you would be venturing into the wilds where no-one has reportedly been before. Probably because it probably doesn't work.

Your best bet would be to convert to manual, because it will remove all these annoyances. As far as I know, there is no Nistune option for the RB25DE, which would have been a nice way to try to make it work because you could tune it to run the turbo engine and it would still talk to the TCU.

I'm still voting for manual conversion. Either that, or you have to look into alternative (aftermarket) TCUs for the tranny. They exist, but that's a whole 'nother set of issues.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
