Hey guys and girls

I have recently had an RB25DET Neo dropped into my R34 sedan...It was auto 2.0L neo and I have put the 25 in and converted it to manual, the loom has been completely rewired and has had the traction control removed. We started it up with no issues at all, took it for a drive and made a few adjustments to the cas and its running beautifully...It is awesome in first gear but the minute it hits 3500 - 4000rpm in second or any other gear it goes into fail-safe mode, turns to crap and gives the engine codes 44 and 46 which are tcs and tps. Apon doing some more research we noticed that we are missing unit called a "Throttle control unit" which appears to be in the 25det only from the r34 range...and being a 20de r34 it doesnt have this unit...We contacted nissan and their response was "Yes we have the unit available, $2000 please." WTF $2000????

My question is... Has anyone else come across this problem? Can something be done to the ecu to remove or bypass the need for this unit so I can get my car back on the road running as a 25det should? or does someone have one of these units that they would be willing to sell to me cheaper than I have been quoted?

Oh and I am running the standard 25det ecu

Any help would be greatly appreciated

Cheers,

      Left & Right Window Regulators for 2013 Skyline V36 Coupe

      Both windows operate normally while the engine is running but start to sag as soon as I switch off.  Does anyone know of reasonably priced replacements or other brands that will fit?

      Actually PowerFC is probably the easiest to get basic data from, it comes with a hand controller and display so you don't need to remember to pack a laptop every time you drive. It also has a PC based viewing/logging option if required. Nissan used consult on these because back in the mid 80s, ODB was just a glint in a standard's body's eyes.  They switched to OBD shape around 2000 (my 2001 Cima had OBD shaped but not OBD compliant port) With the standard ECU there is a cable and software available to give basic data too, I think it is called Nissan Data Scan or s

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      Given by the sheer number of questions about offset, absolutely not. If you had the information formatted this way: Space from R34 GTT hub to outer arch = 100mm Space from R34 GTT inner hub to nearest suspension arm = 90mm. (making this up) Buying a wheel that was advertised as Enkei RPZ5 Diameter 18in Width 9 Distance to arch = 84mm Distance to suspension arm = 76mm 100% of people would know instantly if it fits. They would absolutely also know instantly how close it fits too, and no questions would need to be asked. You would know you would have 16mm from the guard and 14mm from the suspension arm.

      Ah ok, for example for the apexi ecu I heard that it's pretty limited with the information it can give you. Also not sure why Nissan used the consult port over the obd2, what the idea there was.

      Diagnosing with and without is mostly the same. You need to know, as Duncan asked, and what conditions. Car hot, cold, idling, driving, if while driving what rpms, is when you're varying, or is it when held constant.   From there it's understanding what can be causing it. Starting with pretending all of the sensors are correct. Which means if it's going rich, why would it be thinking more air is going in than it is, and under what conditions. So things like if only when under boost, it could be be a loose intake piping joint. It's just understanding the system, and understanding when/how the problem occurs, and then if it's only occuring in specific scenarios, what can be causing it.   ECU specifically, if it's aftermarket, it'll have software you can use, for the Skylines on factory ECU, there is Nissan Consult you can use. Most ECUs have a way to get data from them.
