R34 25 GTT MAF issues i think ?

Hi Everybody ,

Im having a few issues with my R34 GTT i brought it stock about 4 months ago. Before i took it through Regency in SA i have to remove the Gizzmo MSI-BC ( Boost Controller ). i did this buy just unplugging it and the vacuum line connected to it. To be honest i didn't really have a chance to check what the boost controller read before however i did notice that my stock Nismo Gauge as reading 0.2 some times under full throttle. But other times 0.6, i re installed the Boost controller and now my car is making 4PSI under full throttle all the time. ive checked the lines and i dont think its a boost leak ive taken off the air box and fitted it with  pod filter. A friend of mine said its possible the the MAF and also a combination of a faulty boost sender unit as sometimes the boost gauge works but some times not. Car idles and drives fine but just nothing more then 4 psi when my foot is down. Its probably also worth mentioning that the boost controller hasn't been set up so at the moment its just a glorified digital boost controller.

Borrow a non electronic boost gauge and hook it up with a line through the door jamb or window to see what boost you are actually making. Set up your boost controller properly. If you think there is something wrong with your MAF either borrow a known good one or clean the element and resolder the connections.

And put the stock air  box back while you still have it.

      R34 RB20DE NEO + T ONLY

      See my post here If you put the Haltech in, you won't have to worry about any of that. And, in case you're worrying about my lack of credentials in doing your exact swap, I put a Neo in an R32. There has never been a stock boost solenoid near my car and the Neo's ECU has never cared. Nor should it, because it is electronically impossible for it to care.

      That's 100% wrong. Did you wire in the boost sensor? If you did not, then that is 101% your answer. Neo ECUs do suck a bit.

      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.
