Hello every one

Some of you might remember me having a problem where my car would make boost while not moving (not under a load) Well honestly i believe i still have that problem. But that is beside the point. Sine then i have replaced timing belt, set ignition timing to 15 degrees... etc...

But while trouble shooting that issue, i decided to check the TPS voltage to insure that its correct.

I understand that when closed i should be getting about 0.3-0.5 and when open i believe its about 6.0?

But....

I get about 6.0 voltage when the throttle is closed, and as i open the throttle it begins to go up

Then as i continue to open the throttle the voltage goes back down... untill its 100%

I have a 90mm Q45 Throttle body using the RB25 TPS. and its an S1 RB25

the one clip from the Q45 TPS is differnt, but once clip is the same. The clip that is the same is the one i check for the voltage. So i tired the Q45 TPS hopping that my RB25 TPS might be defective but the same thing happens

I plan on hooking up my consult that i just got up this week, to see what it reads for the TPS

And compare that to what i get using the multimeter.

But i just wanted to know what every one thought?

remember i have a RB25 in a US Spec Nissan 240sx...

And the wiring had to be converted to work. but every thing else is fine on the car.

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
