im assuming its the immobilizer signal as its part of the keyless entry system

i turned it off, since i couldn't get it working, its been w while since i messed with it, about finished wit the car so just trying to sort out the last few things, i am trying to use the factory system,,

latest drive.pclx

wire in xtreme g4x in to my 16frs with k24, and ide like to get the immobilizer working, i have imo wire from car going to a digital input, but wasnt able to make it function, car still starts without non chipped key, so im not sure what els that it needs, is the immo sent through CAN as well ? im also looking to get CAN set up to get dash/ac working, any info to share would be appreciated

thanks for the reply , correct i have it set to run when stalled to log the first start, confirms what i was thinking i just have never seen a number that high and thought maybe i had something wrong,, not having to calibrate it is messin with me lmao

getting ready to do first start and i just got the canlambda set up in ecu it connects but reads reaaly high! 148.75 ?? i havnt started the car yet but ive never seen a wideband go above 22-24, so im not sure if something is off or not or if i just need get some exhaust to pass by it

I’ve wired to the above diagram and all is working 100% as intended, thank you

Thanks for the edited diagram, I have a better work around than my original idea Regarding the chassis relay, it doesn’t tbh I’m just going off the factory wiring diagrams while trying to use the relays how the factory Intended, while trying not to modify the cars factory electrical system, only making modifications to my jumper harness adding a relay for key on + to - to control chassis relay, should do the trick, thanks much!

It’s way more complicated than it needs to be but I think I’ve come up with a solution, I just want to clarify if it might cause an issue, more info idk if needed but I’m wiring to a 2016 Scion frs using a kpower pnp jumper for a haltech I’ve re-pinned for the link, & all the relays are wired hot so I can’t change that, I also want to keep keyless entry so I can’t add a relay on battery cable after melting my brain and taking a nap, I’ve come up with the idea to put a relay inline with aux1 at my jumper board/harness to connect/disconnect the vtc solenoid with key, cutting off that feed back, While running other aux channels through ign/inj aux @Adamw does this sound like a feasible solution? thanks

Here is a super simplified version,

Yeah sorry xtreme wire in, I think my issue is 12v feedback from main relay e throttle relay and chassis relay are also wired for low side drive, when set to low side i get error on the aux channel with vtc and vtec solenoids , when set to high the errors go away but car doesn’t turn off,

I have configured the e throttle relay and still getting some feedback or something, have error with low side, and error gone but car won’t power off when set on high side

I found a hiccup with e-throttle wiring/relay, first I had e throttle +/- backwards, fixed that and then did the set up e-throttle and added the e-throttle relay & the error went away but car didn’t turn off with key so sorting out relay, should be fine after that tho,

Link xtreme g4x k24 I have wired the vtc and vtec solenoids to low side, feeding them 12v & the aux 1&2 are red showing error? Doesn’t actuate when testing either, When I set to high side drive the error goes away, Any ideas ? Thanks much!

i would appreciate that, as i havnt found to much info on it, so im hoping to get a little head start if possible
