Drive by wire adjustment? Can someone tell me if HP tuners has the ability to adjust the throttle opening rate on my 2003 5.3 truck motor? So it will act more like a cable TB.
I am deciding between HPT and EFI and this is a key feature I desire.
Thunder Racing has indicated that EFI can perform this function. But I have not taken it further since I am leaning towards HPT.
I have asked HPT and the reply was....
(They (HPT reseller) can also help you with regard to the electronic throttle rate, as we do not offer specific calibration advice.)
Also I found nothing searching the online help for HPT or their forum so far.
Just thought I would post this before calling a reseller...
Thanks in advance.

I don't know about the specifics there, but I used HPTuners to
swap a cable throttle PCM (van, w/ 6.0 & 4L80E, yeah boy!)
into a drive-by-wire Silverado SS. Can't get any closer to cable
action than that.
I know there is stuff for the max allowed torque (which I think
may be what holds the throttle down). Drive-by-wire is the

. EFilive will definatly allow you to change any of those tables. You just have to have the cable plugged in before you open the software and they all show up in red.
With efilive you can change the pcm and its vin to anything you want. So if the pcm you want to use works with another file you can use it for any application. So for example, if you want to take a 2002 v6 silverado pcm and make it a 2000 Corvette then you just need to do a full flash with that corvette file and it will work just fine.

Thanks.
But has anyone with a drive by wire tuned their own set up and changed the throttle opening rate?
Or does everyone leave it as is? Slow slow slow opening time to say the least.
I do not want to change my set up to a cable!

Yeah what he said.lol
I know a few (wait4me) have tweaked the DBW tables to improve responsiveness, but I believe there is limit to how aggressive the tables can be modified before the danger zone is reached.
This is why I left ours stock for the time being. I'm looking for cable style TB consistency myself.
Also, when you get into those files for the ETC in EFI Live, they are marked red, and carry a warning saying making any changes to the tables can render a pcm useless, not sure why but the warning is there.

Yes sir! That's where (Wait4Me) Jessies' trial and error efforts pay for themselves. He walks the line in an educated fashion where us average Joe's don't care to go on our nickel.
I am a gambler, but not with my PCM at stake..sorry. I'll keep the stock tables or pay the dough for the pro

I've tuned many ETC (drive by wire) vehicles with Hp Tuners. Never seen a delay in the throttle blade opening to 100% when the traction control was turned off.
On my 2001 ZO6, I made some changes to the ETC tables when the traction control was on so the traction control was less intrusive.

The only way to really find the limits of these tables per application was to use a roadrunner.
The reasoning on that was that the roadrunner cant be killed as you can always reset it and and just do a full flash back into it and it is a "fresh" computer again.
When you go to far with the etc tables, the pcm will shut you down.
When it does that killed mode, it makes the ecm flag ffff for actual coolant temp internal, Shuts off cooling fans, Sends out reduced engine power on the Bus "which kills throttle control via the ETC module, Sets internal vehicle speed to FFFF "256" but not external vehicle speed. Also by doing that, you can no longer do a reflash or anything with that pcm because the vehicle speed is no longer 0.
Competition ETC modes are usually all i change so that way they are only active and different when you go into comp mode with the switch.

Thankyou everyone for the input.
Wait4me, your explination helps alot. It is always nice to know "why".
RussK, Exactly what I was looking for.. I feel now, based on what you are saying, I do not have to worry about any adjustment anyway.
To explain again better why i ask this question in the first place...When I spoke to a reseller recently on the phone who could also offer a mail order tune, I was told that this was a must have for an electronic throttle to improve the response time.
Thanks again,
Steve
