As topic suggest's, i've got a Wolf 3D V4 pro for my FJ, and my brother just had one installed on his FJ as well, only snag with it was that the wolf doesn't work with the standard TPS as its only an on off switch not a true TPS sensor...Now does anyone know if there is one that you can get off another motor (SR?? CA??) that will bolt up or is it easier to just swap to an XF throttle body at this stage and have one less restriction??? If thats the case, how hard is the XF throttle body to install?? Any cutting and shutting of plenum needed???

Cheers,

Shane

If I go programmable it will probably be a Microleb purely so I can junk the flap air flow meter easily. A friend is going to make up some plugs to make it a plug in proposition, and I'll be running a gutted RB30E airflow meter with wires going into the firewall to make it look like its standard, and the ecu will be in a Nissan ecu case.

Stealth :D

If you want something really unique why not use an SR20DET loom and Apexi PFC . That way you can get direct fire ignition and a choise of MAF's ie Q45 from Infinity .

Funnily enough, thats something that me and my mates discussed at one stage, it could be done, no reason why it couldn't just be easier to use a normal aftermarket ecu...

Adam i was looking at the microleb, but for what i got this wolf for really couldn't complain hehehe

My throttle body is from an FJ20E and was auto.It has 2 tps plugs on it for the auto trans.The second plug is the variable type tps that you need.Maybe some other factoy TBs from automatics will fit.The XF TB is a cut and shut job.My engine is close to 400bhp and it poses no prob(im also using wolf ecu)

Thanks Todd i was kinda waiting to get an answer from you about this!! Seems i'll have to go and suss an automatic FJ tps then hey!!

I was just throwing the idea of the XF throttle body around as an aside issue, i would prefer to keep FJ tb at this stage, and hopefully i can suss something to fit it!!

      Not that I know from experience, but in theory you'd want your gate spring to be as close to target pressure as possible, so you'd go with the higher gate spring?

      Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?   Edit: Actually I might just swap the spring and see what the logs say after another few pulls, as we know it's still spiking without the Mac valve in the picture so I need more data without the Mac valve trying to combat the issue.

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
