Wondering if anybody could confirm for me that the flange on the q45 style throttlebody is the same as that of an xf throttlebody. I've got a Greddy copy intake plenum that is apparently made to bolt the q45 onto, so I'm thinking for the setup I've got in mind (250kw atw) the xf would be a much cheaper alternative.

there's an extra "gotcha" when using some versions of the xf throttle body

do a search. the tps sensor voltage is backwards as the butterfly opens backwards (its in the pfc faq in my sig too)

complete different patterns.

xf is 66.5mm stud to stud and approx 94mm diagonally

q45 is 78mm stud to stud and approx 111mm diagonally

just chop the q45 plate off and run the standard throttle body, there should be no problems with it for 250rwkw.

OR just but the Trust adapter plate

      This. The R34 handbrake icon DOES come up when the brake fluid level is low. You might be sitting right on that threshhold. I have been down this diagnosis path and this was the solution (and it was pretty much as full as your picture is to begin with).

      Unfortunately the cavaet to that is that while any scan tool should be able to read the code, the workshop will need a consult plug to OBD socket adapter. You don't have a location on your profile, where are you based?

      @Haggerty this is your red flag. In MAP based ECU's the Manifold pressure X RPM calculation is how the engine knows it is actually...running/going through ANY load. You are confusing the term 'base map' with your base VE/Fuel table. When most people say 'base map' they mean the stock entire tune shipped with the ECU, hopefully aimed at a specific car/setup to use as a base for beginning to tune your specific car. Haltech has a lot of documentation (or at least they used to, I expect it to be better now). Read it voraciously.

      I saw you mention this earlier and it raised a red flag, but I couldn't believe it was real. Yes, the vacuum signal should vary. It is the one and only load signal from the engine to the ECU, and it MUST vary. It is either not connected or is badly f**ked up in some way.

      @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation.
