Hi... Just done a gearbox conversion in my 34 using 33 parts. Speedo and reverse wiring not wired up yet but car is running and ive been driving it. Last night after giving it a bit of a squirt the engine light came on and now it's on permanently.. I tried reseting the ecu by disconnecting the battery and draining any charge in the wiring but as soon as i connected the battery again and started the engine again the light was still on. Engine still runs great, no missing etc, plenty of power, no problems at all.

Does anyone have any ideas what I should check, like maybe a plug has come out somewhere or something... Closest mechanic with diagnostic equipment is 110kms away so would like to try and sot it out myself.

I had the same, its because you have no speed signal. If there is none it will illuminate the check engine light, only problem with this is the light and it will use more fuel then normal as speed signal is used to cruise AFR control.

      R34 RB20DE NEO + T ONLY

      By Sxnjeet · Posted

      Hello, I'm trying to make this thread basically the thread with all the answers to common questions regarding specifically the RB20 DE NEO + T engine, that comes in the R34. Answers will and only should be provided by those who have done this conversion or actually have some relevant real life experience please. Please feel free to ask questions in the comments if you have any so other members can answer. I feel like this thread is really needed, especially with more Americans buying (unknowingly going to regret it too) rb20 neo r34s. My first question being - What do you guys use for tuning? I have purchased a haltech elite 2500 Plug and play kit for the rb25det NEO because the ecu plug is the same, but I am unsure if any of the pins would need to be repined to match. Second question that I see asked very often - After this conversion, did you install the boost solenoid/ actuator? I see many people doing a + T setup on their rb20 NEOs while running stock RB25DET NEO ECUs with no tune. I am wondering how they are going about doing that and consistently abusing the car because many of these people have had these untuned setups running for a very long time. That was my original plan, but my engine cuts out at 5 psi of boost using the stock ecu with no tune and no boost solenoid/actuator.

      interesting. ive read and heard otherwise over the past year. ive been doing this +t conversion on a rb20 neo using all oem rb25det neo parts including the ECU, and im having engine cut out issues when I hit around 5 psi of boost. Everywhere/everyone ive asked has told me its because I never wired in a boost solenoid/actuator to the ecu, so the ecu isn't getting the right signal once it hits 5 psi of boost, causing the engine to get shut off.

      Something strange is happening. I didn't touch the car since we last spoke on the forums. Yesterday was the first day of good weather, so i took it out for about 2 hours. It started up on first crank every time about 5 times total. I literally didn't do anything to do the car.

      I purchased this one. Very well priced and works great. I was rough with it to see if it will last and had no issues.  Teslong Two-Way Articulating Borescope with Light, Industrial Endoscope Inspection Camera with Articulated Probe, Flexible Mechanic Fiber Optic Snake Scope Cam for Wall Automotive Engine Inspect-5FT : Amazon.ca: Industrial & Scientific
