Hello,

I have the MTX-L Innovate wideband, and will need to get the narrowband simulation from it as i dont have two sensor bungs.

Which wire/pin from the ECU would i need to use to connect to the "yellow" wire from the controller. Or am i able to splice the original narrowband plug from the car and connect it to that.

Car is 1998 R34 GTT M/T

Thankyou

Splice into it, better yet make a clean cut so you don't get anything noise/interference etc..

On my old R33, I just snipped it and joined it straight to the narrowband output on the Innovate LC-1 unit. Worked a treat!

There is two outputs for that. One is 0v to 5v and one is 0.1 to 1.1v i think. In the guide it advises to connect the 0v to 5v to the ground on the original narrowband plug to simulate narrowband.

Would it matter which one to use i would rather connect to the ECU pin 50 then run the wire through the engine bay.

Thanks

use the 0.1 to 1, that's the narrow band, 0 to 5V is the wide band output. Use that for your aftermarket ECU or datalogging component.

Yeah, splice in on the ECU harness, but what I meant was sever the line and have a clean direct connection to the ECU

      RB26DETT Sketchy boost mod?

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
