    OK, thanks. I'll take a look at that. Sounds like a better option than cutting fuel.

    BTW, is there a writeup anywhere about how the COS valet tune works?

    Thanks for replying. I've already considered that but am concerned that if those limits cut fuel delivery, will that cause me any issues with the engine running lean. I've just hooked the wideband...

    Valet tune?

    I'm thinking about taking my 2002 C5Z to get a new front bumper fascia installed and painted sometime soon, but really don't want someone possibly joy riding the car while it is there. The car is...

    Well, the last time I did a run that went into boost, I simply put it in fourth gear and just ran up the RPMs. At 69% throttle at 1751 rpm I was already at 105kPa. I was at 182kPa at 3700 rpm when...

    What will a B3618 table look like on a typical boosted car? Sloped downwards sharply when boost kicks in and then flat lined out to redline with 0.78?

    OK, that makes sense. And it actually might be relevant in my case since I am getting that REP fault at startup, so maybe the PCM is getting confused when it goes through the motions of testing the...

    Thanks.

    I see what you mean by B0101. I smoothed out that range to make smoother transitions between cells, so I'll see if that helps. And I'll take a look at A0009 as well and increase the...

    Sorry, been away for a while. Mostly because of rainy weather.

    Anyway, got the new wastegates installed and did a couple of runs with them. Boost is now hitting 11.6 and 11.7 psi. Everything...

    Attaching the wastegates directly to the turbos just seems more efficient to me. I am using 14 lb springs, expecting there to be some loss to compensate for at the intake. These are rear mounted...

    Yeah, it still startles me when the turbos kick in. It's like a giant hand on the back of the car giving a huge push.

    Well, I'm seeing some pretty lean figures in my map from my last log, so won't this filter out those cells as well? Since switching to E10 gasoline, it's made some rather lean cells up in the higher...

    I've got a question about the filter being applied to the map. Specifically this one:


    Why are the values over 1.06 being filtered out of the data?

    OK. I think.

    The way I've been looking at this might not be the way that tuning actually works.

    But perhaps the logic path I have taken to get there is wrong.
