Hi mate's i got the new LM2 wide band and it has a OBD2 log feature.

i was first wondering if the 95 rb25det s2 is OBD 2 i think it is.

and does anyone know of a plug adapter that can convert from jdm to American style OBD 2 plug.

there is a plug by the fuse panel is that it.?????????????????

so how could i use this to log info using the lm2 wideband unit. does any one have some kind of addapter plug for this.????????????

Pretty sure you cant just use an adapter plug, as the protocol on the wire will be different.

Also, you cant use wideband for closed loop with the factory computer so you wont be able to read it from there anyway....

thanks guys, the LM2 does have inputs for rpm and so on, but if i could have used the obd2 plug then i would be able to prioritize all my channels that i want to log.

I took an output from the Lm2 for afr and send it to the power FC datalogit 0-5 volt extra input. after a get a new laptop that can run on external battery power as mine is mest up, i will do a log from the fc datalogit and post all results.

That was my main reason for wanting to use the LM2 because it uses a 1g sd card for all logging purpose.

you could try hooking it up to the EGT input on the ecu then logging via consult? i dont think its ever been tried before, and not sure if the ecu ever does anything in response to EGT temperature, but when looking at EGT via consult its always 4.98v (possibly gets lower as the egt gets too hot)

      WA PITS: Am I screwed?

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
