Engine Running Badly After Auto To Manual Conversion!

Just finished my auto to manual conversion and took it for the first drive. Now the engine is running like crap. It hesitates between 2000 and 4000 rpm and wont rev past 5500rpm easily. It revs fine in neutral but as soon as there's load on the engine it carries on like this.

It worked briefly for one quick squirt but that was it.

Now could this somehow be caused by me still using the automatic ecu (which is chipped)?

Another thought that has crossed my mind is bodgy fuel because the car hasn't been started in about a month?

What should i look for? I really want to enjoy my new manual!! :O

Looking around and i just noticed this...

Adjust your base timing to 15 BTDC on the CAS

Either fit the neutral switch wiring or ground pin 44 with a stock ecu. It needs that signal.

Now i don't think the difference in base timing could be causing this.... but could it be the fact that i haven't fitted the neutral switch wiring or grounded pin 44 on the ecu? What exactly does this do?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
