Second option sounds like the best one for me. @Adamw what is the process for getting my ECU returned to have the work completed?

Bump

Hi all, I am wanting to add DBW to my RB25 Neo, and im chasing some advice. I've read that i may need to send my ECU back to have 2 additional AUX (9 and 10?) and 2 additonal AN VOLT flyleads added for this to be able to function with the GTT plugin? After going through all my connections, I've found that i have *potentially* 2 spare AUX - AUX1 (intake/WG solenoid ECU pin 104) & AUX4 (ISC solenoid ECU pin 11). Im assuming i can use AUX 1 as the factory WG solenoid doesnt exist anymore, and AUX 4 as the E Throttle will do the idle control? I also have ANV 2 - Oxy (not being used), ANV 3- Factory MAP (not being used) and ANV 4 - TPS (can be reallocated to E Throttle. This leaves me one AN Volt short. (I'm using 1,4,5 and 6 currently). Am i right to say i can just buy a second XS Loom for the 4th AN Volt i need? Or is there an AN Volt i have missed i could use? Thanks!

Hey all. During the week i hit the AC in my stagea for the first time since installing my GTT G4x plugin, and it blew the 10A "ENG Cont" fuse in the under bonnet fuse/relay box, which killed power to the ECU. Does anyone know if a pin needs to be moved at the ECU to fix this issue? I can see the following pins on the ECU relating to AC: Pin 109 - AC clutch relay flywheeling (12v const) Pin 14 - A/C clutch (Inj 7 Aux) Pin 21 - A/C in (DI3) Pin 78 - A/C fan (Inj 8 Aux) Im guessing it has something to do with pin 109 as it is a constant 12v feed, but im unsure what i should be moving it to. Also, does anyone know what a good base to start setting would be for launch control parameters for an RB25DET neo? Thanks in advance.

@Mcfly94 I don't have anything to help with your question, but did you have the injector deadtime info for the 1250s still? I've searched everywhere and can't find any charts

Im using AN Volt 1 (MAF) for MAP.

Ah right!I actually wrote this down a while back and forgot what it was for! Will it be ok to reuse AN Volt 3 as the input?

Hi @Adamw, in regards to the above, can i run a wire from the fuel gauge to AN Volt3 (PIN 47 factory MAP) to use for fuel level?

To get fuel level to send to my PowerTune Digital dash, do i need to send the fuel level to the the ECU first? or does the ECU see that data already and i just need to setup a CAN stream? Likewise for a low fuel warning?

So i happened to find that function last over the weekend, not knowing exactly how it worked, i had assumed it would allow me to see the coilpack fire with a DMM. Bad idea leaving the spark plug in the cylinder.. Loudest bang i've ever heard. No idea if that caused any damage to the engine or is causing the current issue.

Ok, made all the changes. Also found 2 blown ecu power fuses, which is why the ECU was seeing ~10v when the battery was 13v+. Car now starts and runs, but not on all cylinders. I have Bosch R8 coilpacks, is there anything that needs to be changed to suit these? I've tested all the injectors using the test function and all are firing. Is there a way to test coilpack function?

Thanks for the reply @Adamw. Missed the trigger 2 sync mode. Base timing has not been checked (no timing light), but when speaking to Geoff from NZW he said it should at least start using the settings he provided (i realise it will need to be checked) I did notice the low voltage. I have a lithium battery to go in, just waiting for a charger to arrive so not wanting to kill it before then. Have been using the old battery (which is actually showing 12.7v) Will change active edge to rising.

So, I've finally gotten around to getting this to the point of starting, but i have issues. Car will crank, but will not fire. I took a quick log of me cranking the car over but im not really sure what i should be looking at. Another issue i've noticed is that my ethanol content sensor only works if the pull up is ON, and i noticed that the fuel temp is showing 200 deg C (which it definitely isn't). I've attached the base tune, and the log of the cranking. Any insight would be appreciated. Stagea1.pclx PC Datalog - 2022-01-15 6;23;38 pm.llgx

If i convert to E Throttle, can i then ditch the IACV?

Just finalising wiring/install for my GTT G4X plug in and have a couple of questions: I will be reusing the Oxy Heater/AUX 7 for my MAC/boost solenoid, and was wondering what wires i need to use? RB25 runs a 3 wire with Sig/Heat/Heat, im assuming i use SIG and 1 heat? Can i ditch the IACV and have the ecu/TB control idle using the Idle Ignition function? Thanks in advance!
