Hey guys so I found oil in my tps (rb20det) I cleaned it w contact cleaner and the only reading I can get from it is 13v or 10.5v. The multi meter is set on the v- with 3 dots under the dash at 20, im a noob with multi meters lol. I know tps's have been coverd many times but I think mines a special case lol.

Ahh, thanks, ill check mine, dunno how sump oil could get there, theres no oil lines near there...

Oh! the pcv valve! its letting oil vapour in the intake maybe.

Try an oil catch can.

Oil gets in there from your rocket cover, Im sure you are aware that the rocket cover hoses feed into the inlet before the turbo and also the plenum. Thus sucking oily residue from your engine into your intake system. After 20 odd years for a r32 anyway thats A LOT OF OIL! ohmy.gif

If you pulled your intake pipe off (assuming it hasn't been touched over the years) it will be caked in oily gunky grease. Pull your intercooler and pipe's off they will have oily residue in it throughout also. So naturally your TPS valve and plenum will also have oil in it.

If its an issue consider a catch can. Its good to give your pipes a good clean out and de grease every now and then.

ROCKER

And the oil usually comes to the throttle body via the turbo, not via the PCV valve.

Oil gets sucked into the intake via the breather then pushed to the throttle body from tge turbo. The seals on your throttle body might be leaking hence oil in tps my 20 year old tps was clean as a whistle throttle body was sealed.

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
