Altering Electronic Throttle Rates on E38

[gmh308]

The table I posted earlier is not the one I'm looking for. The ones I'm looking for can be seen in this screenshot. However, I am unable to see these tables in my version of EFI Live. I'd like to know what I need to do to be able to have access to these tables.

Even if you could access that throttle map you would get very little movement before the controller went into limp mode. That table is checked against yet another table that is almost a mirror image of the one in your pic which cannot be accessed. More than a few % out and bingo, limp mode.

So C6guy, short answer to your question is no...... at least using EFI Live, or any other commercially available tuning software. If you can do some hex editing and what not, anything is possible, but last time I checked hex editing required a degree in rocket science (at the minimum) and a whole lot of patience.
Sorry man, wish I had better news... but some things in the controllers are better off left alone!!! Bad things can happen to you or anyone around/near you if something goes wrong!!!


BTW... What happened to the screen shot of the throttle map????? Was kind of interesting to see!!!

Chuck, can you please resize your CoWlisle 2012 picture, we've had complaints from people not running 24" screens that it's a little excessive

Ross My Pal.... You know that I would do ANYTHING for you....and all you have to do is ask!

The BIG problem with your request this time was weather to crop the pic to show the CoW GIRL's breasts or her pretty face....

Not wanting to only show half of her, the best decision was to remove her..... DAMN!

At your service!

Can someone tell me how to go about altering the electronic throttle rates on an E38 PCM? When I look at the OEM tune, all the values are set to 99.99 in the table and there is a note that says not to mess with them.

Is it possible to adjust how the electronic throttle responds on an LS3 with an E38 using EFI Live?

Not sure if you've tried this already, but there is a ton of tq management on these engines that isn't really needed. Clunk reduction, tip in reduction... I disabled all except traction control by blade and love the way it drove. I think your problem is caused by tq management rather than poor accelerator pedal mapping

Just my .02

Regardless of what's happening in the tune, What I've done is very different.... Click the link in my signature and look around for other posts on the subject with "CoW BOOSTER"

You'll see what I'm talking about.

I think I understand what your selling and claiming BUT I dont understand that it makes zero more hp and it doesnt improve ET BUT it will feel faster? Do I have that right or am I misunderstanding?

Will do. Rarely am I on here on my computer and this wonderful phone app hides sigs. But I'll check it out
