    I haven't really nailed it since the new pump has been fitted because I was waiting for the FMIC to be finished, I will do some logging tonight. Block 031 is Lambda Factor which is what Bill logs on his rollers so that should give an indication of fueling.

    Since it's been fitted I have noticed how much quieter it is when primed before starting the engine. My old one was really noisy and I cant even hear this one.

    That's what i'm experiencing too, failing fuel pump, my car is a narrow band so i have to use an inline fuel pressure gauge.

    My pump was knackered but the car started up first time, you'll probably find that you'll start going on the lean side on fuelling as you hit full chat. Mine's struggled 5k upwards at just 16psi

    Exactly the symptoms I was seeing on the rollers. I'm hoping that the logs will show a huge improvement tonight.

    This graph shows my struggling fuel pump. The bottom left graph.

    [​IMG]

    Where the graph lines start heading back up is where the pump was unable to produce the amount of fuel requested by the ECU. I'm hoping that the next time i'm on Bill's rollers that line will stay down in the 12s ;)

    No doubt you should see an improvement, post the logs up later if you can :)

    I think dependant on if it's mapped the S3's need a new pump once they hit 100-120k

    My old Chipped UK definitely finished off the pump. 2 years of a lean map made my pump dump fuel in all the time to keep it cool.

    I'm still waiting for my wheel adapters. They were sent on the 8th. USPS and Auspost combined are very unreliable. Sometimes quick, predominantly slow.

    Finally got round to loggin the Toyosport FMIC. Wow what a difference to cooling it makes. I gave har a big thrashing and pulled over to touch the inlet mani, icy cold.

    [​IMG]

    It was 18 degrees ambient temp and I saw a max of 33 degrees on boost mid 20s on cruise. Now that's a bit better than 50 degrees!!!

    I may have a boost leak somewhere as the car doesn't seem to be pulling as hard as it was. I'll go round the clips and tighten them all up tomorrow.

    Very happy :)

    031 looks like it's been sorted :)

    Fingers crossed it doesn't lean up if you do find a boost leak, just out of interest Westy, what was the temperature outside?

    Just been out 15 degrees amb, late 20s on cruise and drops like a ***** from the onset of boost to 22-19 degrees...i will have to log the same as you,to show you
    I cant understand why your temps dont plummet on boost??

    Yeah I dont understand either. The only difference is you have a hybrid. Are you still running 24psi?

    yeah 24 psi i will log mine tomorrow night, all i can think is the hybrid is spooling faster?? anybody else with a fmic with logs of 118??

    Its very interesting for me as it is favouring that i dont have a pressure drop as it would be very hot if its boosting at 28+psi (not tested yet by the way, other work things have come up) unless its throwing fuel in like a mofo....:blink:

    I just had a look back at Tam's logging from a few weeks ago. His intercooler is the same size as my old one but 2 mm thicker and he was registering colder AITs then I am on my Toyosport :think: I'm going to swap my AIT sensor with his tonight and see what results I get.

    You're right mate. I'm going to fit a FMIC sprayer too and see how low I can get the damn temps.

    they will be converging on the same temps... Do you run a phenolic? your apparent plumet is the AIt sat in the warm inlet manifold vs neils which is cool inlet manifold (cos of my phenolic insulator on there) so all it see's is actual airtemps, not engine temps skewing the ait sensor..

    My theory.. based on not knowing if you have a phenolic on yours dave

    danes.. on load.. until clutch went *nah* - 3'C rise over ambient during a run at 22psi boost
    chemically enhanced cooling of course as well as a larger fmic now

    Bill can you explain why Tam is getting better AITs over mine with a smaller core, same turbo and one of your fantastic gaskets?

    If you look at 390.09 you can see where it has dropped significantly on full boost... (Ignore lol)

    Westy are you a Tam running the same boost pressure?

    390.09 is on the way back down i think Dave, but you're right, from 380.13,4300rpm the temps keep going up
