Shiv: will doomsday users be able to adjust the user torque % ?

I can't say much about this until that related user adjustable parameter is ready which may not be for a few weeks. I was hoping to get it out with v3.1 but didn't get to test it enough.

am I lost or has V3.1 not been released yet?

They can adjust it but they shouldn't (as per the instructions at the download site). At least not yet.

Not to the public. Just to a few beta testers. We will release it, in beta forum to the general public next week. Probably around Wed or Thurs. Just finishing up the user software interface right now

Perfecto!

just checking. so some time next week if things look right?

Running too high of a User Torque level on pump gas can result in poor performance and, at worse, possible engine damage. 0-100%

Shiv, why the suggestion to leave the default value of 80% User Torque alone?

Previously, you said that 93-94 Octane users, pre 29.2/v81 should be safe with 90% User Torque values.

Has this parameter been re-ranged? Or is the suggestion to leave User Torque at 80% more of a catch-all for those not datalogging and/or post 29.2/v81?

Are there any more of the new features that 29.2+/V81 (doomsday) will not be able to use besides user torque?

If there is a leak in the system (or if the car is running at very high altitude or if there is mechanical degradation to the turbos themselves), the turbos will spin much faster to make the same boost pressure than if there was no such issue. So looking at boost is of little relevance as it doesn't really tell you how hard they are working. The only way to accurate gauge how hard the turbos are being asked to work is by measuring how much the wastegate must be closed in order to achieve the desired boost. And this means monitoring wastegate duty cycle.

The default settings for this parameter will be 60% since a typical v3'd car running up to 15psi at sea level will operate at a max of ~55%. Running the turbos much harder will simply induce more heat and unduly compromise turbo longevity. This max wastegate DC setting is simply there as a failsafe to keep the turbos from working unusually hard and unexpectedly crossing over into "no man's land."

Shiv

Is there a way to determine efficiency of the turbos by measuring boost vs duty cycle (and perhaps temp)? Would such measurements be accurate enough to assess a problem?

To measure efficiency, you'd need (among other measurements) compressor outlet temp (pre-IC) and this is not available with the current sensor layout in the car. You'd need to add a thermocouple in the IC pipe just downstream of the compressor. After that, it's pretty easy to do.

At this time, no. And in the near future, you'll be able to adjust UT.

That's just our "official" stance. Realistically though, it's okay to raise UT as per prior suggestions. The only problem is that many people tend to raise them too high and/or dyno test with marginal cooling fans and wonder why their dyno numbers are lower than expected.

Shiv

[per]

I am running 94% on map 1 non doomsday, i did a dyno on 90% and 94%, the gain was 5 hp and 19 nm by raising the settings from 90 to 94%
I am using shell 99 octan (US 94-95 Octan)

Has anyone else raised the settings and messured what i will do in hp and torque?

That makes sense. But could one simply diagnose the severity of leaks and turbo problems with the current sensor layout?

Presumably this would require that 1) the wastegate duty cycle, IAT, and boost values all correlated well consistently 2) the values were relatively consistent across cars, and 3) there was a known good range from which to base a comparison. Is this the case? If so, could one reliably use this diagnostic to rate relative performance? For example, "10% under spec"?

Will current v3 users need a new harness for v3.1?

No..Just download new software.

That's all

It's 100% Free.

Elegant way to justify the huge extra cost of a V3 in comparison to AA or JB

Seriously talking, I guess whoever among us bought a V3 was kinda hoping for such developments, and I have high hopes the Godfather won't disappoint any of us this time around

Actually, besides the whole software upgradeable thing, one way to justify it was that we actually designed it. We didn't follow someone else's lead and copy it.

As for v3.1 release, i'm just waiting on the software engineer to finish up the user software changes. All this time, we've been testing on my programmer software. That user adjustable window/functionality just needs to be imported to the user software. Simple but time consuming. I've been given an ETA of Wed
