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)

      Reading your posts Josh, sometimes I feel like I've gone in a time machine back to the 90's when everyone was doe-eyed and figuring things out for the first time.  I've lost track of how many single turbo GTR's I've seen on track that haven't burnt down lol. Everything has been figured out a long time ago. These things are at the point now where its essentially turn-key to go single turbo.

      Among other things yes. Making sure to either use an oil pressure regulator or the right restrictor size for your oil pump/range of oil viscosities you intend to run, making sure you plumb the lines correctly, turbo should be placed such that it siphons properly even when the water pump isn't turning so you don't boil coolant in the turbo after shutdown, oil return should be low resistance and also preferably picking the one that is most likely to return to the pickup as opposed to some other irrelevant part of the pan. It's far from impossible to figure this out but I have seen people really, really struggle and if that's the case it's easier to just take the path of least resistance. To me, bolt-on twin turbos are a fixed cost whereas single turbo is almost unbounded.

      Latest round of updates on the car. I purchased and installed a SWS clutch slipper to help with 60ft times and got some second-hand good condition 275/40R17 Hoosier DR2 radials. Test and tune in November showed the tyres were an upgrade over my over 15 year old mickey Thompson's and I got a 1.8 second 60ft and pb et of 11.71 but even then, that run wasn't great due to rain and driver error (the event got called off 10 minutes later fast forward to the weekend just gone 25th of Jan and there was finally a break in the weather to let racing happen. The first run the track was slippery and only managed a 12.1@129 Second run the track was better and got a new pb et and mph: 11.54@131   Lith and I then worked out that I installed the previously mentioned clutch slipper incorrectly and its never been working, and I had just been dumping the clutch the entire time, we also noticed it was on street boost and not race boost. So I lined up for a third run with the car turned up in the first two gears, but the passengers side axle objected to clutch dumps and left the chat which stopped my weekend.   so there will be another attempt in the future once I replace the tyres as they rubbed and are stuffed now. but a low 11 should be on the cards.

      Turbos don't require pulling the motor apart so that's "easier". I would recommend the Nismo R3 turbos instead if you want to do stock twin turbo. It doesn't make as much power as the 2530s but it's only like ~50 whp off the mark and should have better response (ball bearing CHRA, slightly smaller turbo). A local that went with a Garrett G30 and 6boost manifold recently nearly burned his car to the ground after the hood insulator started melting and and burning so if you go single turbo I recommend doing a lot of research and validation work to make sure you don't do the same.
