2.5bar for E38 ECM's features and devtest results

[DSteck]

Crap... I wish I could view which OS I have on my car from work.

DSteck, just use HPT and open your file, and then you can by going to "Edit, Calibration Details". You don't need to be connected to the vehicle.

ok fixed in next beta.

Chris...

Any update, guys? No rush, just wondering. Thanks!

[Bill@HPTuners]

Pretty sure its fixed now james, shoot me your hpt file and I'll verify and send you the new beta.

[RWTD]

Just sent it, Bill! Thanks buddy.

I was at work. I didn't have either my tune file or HP Tuners handy.

Well I finally used the virtual v.e. table to tune an 06' Vette with a 7.4L (LSX block). The car was in terrible shape if you turned the maf off before I started. I ran the car on the dyno for a while and after enough tuning I made a mild 545RWHP and 543RWTQ on 91 octane with the car in open loop SD. It took quite a few adjustments to get the desired fuel and actual fuel to match. I wasn't able to get it perfect, but pretty damn close considering what I started with. The beta update other than one bug I ran into it is a big improvement for the new pcm's. I can't wait for the new actuall release.

well we ran 10.9@134mph last night with the HPT custom 2 bar os for the e38 using a stock L98 engine in a VE Holden ute..

the car has been running the 2 bar os for a long time now and hasnt missed a beat!

much much better than the other so called soultions out there

Hey guys, just checking in on the update for the '06 Vettes, and wondering if you've made any progress on applying the 2.5bar for those. I have a ton of A6 customers with forced induction dying for this. Could they just flash in an '07 PCM/TCM file, and then go from there, since you offer the 2.5bar for some of the '07s already?

Also, have you looked any further into doubling the injector limit, a la the '09 LS3/LS9 Vette? With your awesome MAF range extension, the injector limitation is the last of the piece of the puzzle for the A6 cars and their "estimated torque" issue with ratioing. If it's not very possible, then possibly you could look into allowing for modification of the torque estimation going to the TCM.

Thanks!

We currently have no plans to modify the ifr table as the amount of work involved is simply too time consuming.

I recently did a 2.5 bar tune on an E40 05' Corvette using a Duramax map sensor. Fighting some high IAT's, but it did make 790RWHP at 16.8psi. I first bench tested the sensor and it was almost exactly 2.5 bar. I am at 2300+ feet altitude right now so I didn't expect perfect. On the car I tested it again (using a mighty vac hand pump which makes boost or vacuum) and at about 22psi it reads right about 248-255kpa. It's hard to get the gauge to exactly 22psi. I had purchased the Cobalt map sensor to use since it would be nice to wire the IAT right into that and take that right out of the mess also. The Duramax map sensor though just plugged right in and worked. I had no idea that the Duramax map would peak so low though.

Any word on 06 support?

[Bill@HPTuners]

Not as of yet, still on our to do list.

[VORTECMAX]

Which OS's are supported? In BETA i.e.

Too bad! The A6 cars will have to continue to suffer from incorrect torque values, and potentially have internal damage.

If not IFR change, then how about you give us a torque value modification, so that we can still report proper values to the TCM?

[Bill@HPTuners]

James we currently have no plans to revamp our custom operating systems.

Thanks for your reply, Bill. Maybe we can also get Chris to chime in with what he feels is a reasonable timeframe that he *may* be able to implement either of these two features in the future? He previously stated here that it's potentially doable:

ya maybe there is some way to scale the airflow used by the torque calc or the raw torque number, i dunno but that would seem the easiest way to untrick it.

the IFR patch is still possible it's just a lot of work on top of what already is a lot of work for 2bar.

i have this vision of a dog chasing it's tail...

I know you guys understand the importance of such features for MAF based forced induction vehicles, especially the A6 cars. I also know you have a LOT of work, and you need to chase what is likely more important areas (new vehicle support, new parameters, etc.), and that form of business model is definitely understood, especially in this economy.

Possibly I look like the lowlily tuner asking for such enhancements, but I hope there are more tuners, both us pros and DIY'ers, who can value and understand the importance of them from a proper tuning standpoint.

Thanks for all your efforts, regardless of these issues I've presented.

P.s. Last question (might as well throw it into this post, too), is the LS1 and E40 based pcms any more difficult to modify the MAF table range extend to 15k Hz, like the E38 is? Imagine the capabilities we'd have with LS1 and E40 MAF based forced induction vehicles with an extended MAF table range!

Sincerely,

James

Cool stuff. A really dumb question but here it goes anyway. How can I tell what PCM I am tuning other than by looking at the computer itself?

[NICKY BOY]

Sad panda.

ME TOO!

Monthly check in... Anything new for '06? You're probably sick of hearing it. Can I donate money to help get it for '06? Haha.
