what real gains are to be had removing the carbon canister anyway..1kw maybe

I also remember reading somewhere that in Japan race and drift cars are required to keep them, anyone know if this is correct. Cause those cars are mighty quick so it seems to me removing it is pointless and a waste of fuel..

How did you go removing the evaporator etc. under the dash? Or you not going that far.

I have removed the A/C from under my dash & its not hard...

Remove glove-box, from memory theres a plate behind there so remove that too. Then next to blower, directly under glovebox, is the A/C core in a plastic case, which is held in by a heap of bolts. Remove that then you can split it in half (held together by tabs) pull the core out, & refit the plastic case. This plastic case acts as part of the ducting for the heater & fan so if you use these, it needs to be refitted or replaced with something similar (have seen 4" domestic A/C tubing used) or you will have nothing.

Few things to note but...

The alloy A/C fittings that poke through your firewall are part of the core so if you remove it you will have two holes in your firewall.

Some grommets from Clark Rubber will fix that.

There will also be two holes in the plastic case where these same fittings poked through that. Once again, grommets or something similar will fix...

& lastly, I would suggest putting some flywire, etc between the two pieces of the plastic case when re-assembling it. Without this you will have a lot of leaves, etc come through the vents that the A/C core used to catch.

Fair bit (but not HEAPS) of crap caught in & around my core when I done this...

I think there would be no performance increase what so ever. I mainy removed it so I could mount a catch can in it's place and remove a bunch of vacuum lines.

I think most people would be removing them due to engine bay tidy up/making more room.

i hope you didnt just let the air con gas out.

R134a is Lethal to the atmosphere
R12 is also lethal yet no longer in modern cars and usually only seen older vehicles that are yet to be converted to r134a there would be a plate in teh engine bay stating which type fo gas you have. and if serviced by a air conditioning place and replaced with minus 30 thered also be a minus 30 service sticker in there properly. unless was done in a back yard job.
There is a cheaper gas going round which can be let out into the atmosphere though. known to most as (Minus 30)

Just for fi anyone views this thread for the same reasons please take your car to a registered Air conditioning place to get it properly removed.

      Trail braking done right, should have the rear unsettled, such that you're actually turning the car by a noticeable amount WITH the brakes, and hence noticeably less steering input.

      No you don't. Just no more driving in the wet, and clean your window manually before you drive

      I'm not sure if they tick your boxes, but Haltech would be my pick. I'm an Adaptronic guy from way back, and Haltech acquired Adaptronic to basically get Andy, AND his IP on how he does things like fuel modelling etc.

      Misfire/stalling issues

      Just on this, as there's a huge issue in your assumption Dose.   The logic you've given, is the same logic old school NA guys give for "needing back pressure" in an exhaust. If you free up an exhaust system, and keep injecting the same fuel in etc, at the same timing, you'll typically drop power. Freeing the exhaust will often make an engine want a little bit more timing, and even sometimes a little more fuel, but then it'll make even more power.   There's many mods people do and "get no extra power" when running a comparison on the same tune. Imagine a car tuned for 91, but now we say put 98 in it, see no difference. But as we now have 98 fuel, you can run more timing, and make more power, as the 91 was knock limited.   So just be very wary in your claim of "don't retune it and do a back to back and you'll see". The correct approach would be tune the car with stock manifold, swap the manifold to aftermarket, and retune it again. But no one wants to do that, and all the results we get are "this was stock, and this is manifold changed and tuned" and people put it all down as just the tune doing it.

      Rb25det neo issue tps voltage

      By MBS206 · Posted

      Unplug ECU. Unplug TPS. Unplug boost pressure sensor. Now, all the wires, placing your ground (black) multimeter lead at the ECU end, measure resistance of the 5V line at the boost sensor plug. Then do the same to the TPS plug. Then do the same for all the other wires that relate to the TPS, or boost sensor.   All of your measurements should be very very low. You're looking to see if wiring is out of wack here.   Secondly, from memory on the R33 (not a neo motor, so I'm assuming an r34) the ground wire for the TPS and boost sensor are NOT equal to ground of the car/battery. IE, DO NOT connect ground of the sensor to the engine/body of car. You'll get a ground loop, and/or potentially screw shit up. In electronics, ground for a circuit, is not necessarily equal to ground of another circuit.   So this leads me to ask, when measuring your 5V, how are you getting 1.5V? Where are your multimeter leads touching for both the red and black lead on the multimeter?   If you're measuring power on the sensor wire, and putting ground on the car chassis or negative battery terminal, that could be all of your issues in "getting 1.5v". Electronics engineers can do some funky stuff with circuits, and when both sensors are on, it's enough laid to alter how the ECU is functioning.
