Hello

I have been searching and found nothing in relation to my question. Just a few key words here and there and other very useful info.

I just installed my M-300 plx wideband. I have the schematic to wire in the analog signal for closed loop operations.

to anyone who has done this... did you wire in the 20ohm resister and if so where did you tap into. I see nothing listed under the rb25's ecu pinout for o2 heater. I was thinking it could be for an RB26 setup.

I'm running Power FC standard with FC datalogit.

ps

could I also just insert the analog wire from my plx analog output into the FC datalogit analog input?

not sure how those widebands need to be wired but for any wideband it should be a simple case of wiring it up to switched and fused power for the controller and the heater then using the analog ouput(s) for closed loop or for your datalogit. heater power doesnt have to come from the ecu

if it has 2 programable outputs, use 1 as a narrowband signal for the ecu (make sure its turned off while tuning) and use the other as a 0-5v into the datalogit for tuning

Roger that.. yea I remember reading to turn 02 feedback off while tuning lol... I forgot to do it the other day and the wideband froze up.

thanks that is pretty much what I thought, just wanted to clarify before I went and blew up my PFC.

ps

does NOVA stand for Northern Virginia?? if so im from Maryland and I use to hang out with the slideways crew while there. I think I seen your car on a U.S east coast forum before.

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
