Alloytech PCM requests

[VTuner]

Dare I ask...

I think I know the answer to this question as I have read the posts by the solstice/gxp users, but...

I would like to see access to torque structure tables to allow more torque to be requested from turbocharged Alloytec applications. I see the solstice/gxp users clamoring for boost control; Bosch ME9 is using a torque based structure which is governed by calculated load requests, so perhaps boost control is not really an accurate request for this application.

Am I in the same boat as the GXP/Solstice crowd? Is it possible to crack these features given time or is it that there is a large upfront cost to purchase access to the code from Bosch, so there must be enough user demand to justify HP Tuners buying this level of access?

Thanks!

Given time, probably, the main problem with the alloytec style pcm is the coding in that there is no order or organization to it making actually finding whats needed VERY difficult as compared to the other pcm's we support.

There is no purchasing done, all the cal work is done in house and is very time consuming to say the least.

I would also like to add ability to adjust electronic throttle position versus load at some point. Please add to the wish list!

Thanks for all the support so far, you guys are great!

A few VCM Editor requests that would be most helpful:

Boost Control (Desired Boost): As I indicated previously, this may be controlled by an internal table that is limiting maximum torque at any given RPM, but I can log Desired Boost and watch it drop quickly above 4000 rpm regardless of how much I increase Desired Air Load and Max Air Load Torque in this range.

Displacement: If you can provide access to modify the calculated displacement volume a lot more could be accomplished (via scaling the torque model), even without access to the boost calibration tables.

Speed Limiter (A lot of customers would like this raised or removed; BSR offers this in their tuning packages for the Aloytec 2.8T).

Thanks again for a great product!

We need a scanner log of the speed limiter kicking in while logging as many spark & fuel pid's as possible so we can determine if it pulls spark or fuel & at what speed.

We haven't been able to locate it in the code so need to know where it is so we know where to look.

OK, it takes nerves of steel to hit 155mph on the snow covered roads of Vermont, but I am willing to go to any length for you guys.

Bill, I just sent you the scanner log you requested.

It doesn't pull spark or fuel. The Boost DC% and Demanded Throttle % are both manipulated to regulate the top speed.

ill get you one of the speed limiter next time i have one come in..

Already done.

The following sensors are not currently supported (In VCM Scanner) and I would like to add them:

Wideband O2
Intake Cam Timing
Intake Pressure

Thank-you!

Is not Lambda the same reading as WB02, but rather in a differant format?
At least as far as I had logged it, lambda isnt pulsing, and there are only two sensors in the exhaust stream, the Wideband, and the Narrowband (which is only for emissions check)


I could be mistaken, but I would look into it, it seems pretty accurate to me


More control over boost as vtuner requested would be a huge huge improvement

[Bill@HPTuners]

I'll take it.

Make sure you include its cooresponding .hpt file as well.

[VTuner]

The wideband, intake cam angle, and intake pressure are all present in the latest betas, the post where I requested these features is pretty old.

no worried bill give me a couple of hours and ill email it too you

Bill,

I just PM'd you two .hpt files for your reviewing pleasure.

Thanks

[VYSSLS1]

did you send him the log to go with it?

[VYSSLS1]

bill,
email sent

[VTuner]

Yes, yesterday. Just curious, which version of the alloytec are you logging and providing the .hpt file for? I am sending the 2.8T (184kW) files from a 2007 Saab Aero.

As my Japanese friends would say: this sounds like "noodle" code.

Bosch to thank for this family of labyrinth pcms :P
we have a saying in AU, "sh*& from ar^*hole to breakfast time"
that said ive had some fun with my ride - ute with 175 KW block, 6 sp manual.
one of the bigger turning points tuningwise was when the PIDs that let you alter "max ve" and "desired airload" were added, by jeeze it helped to breathe life into the engine response, - thanks again guys!
