A buddy of mine is only seeing 87% of throttle neither of us have the software to look. but I was just woundering if this is the tune that gm put into the car?

 

Mine said 88%, we set it to have 100 throttle when the pedal was at 85%, problem solved.

 

did u see a difference in power when u did that?

 

cuz i don't see higher than 90%...however i don't have access to HPT

 

I don't know, we set it like that before we scanned it.

 

How did you find out hes seeing 87%?

 

If you scan it, it has a graph that says "TPS (%)"

 

I put a scan gauge in the car and checked, I just thought it is odd that they would tune it that way.

 

That;s weird.......

 

ETC % will show 100% if you change the scanner settings

 

i can see my % through my interceptor

 

your talking about PE hot enable numbers... he's talking about TPS%... and every else is confused as hell.... ignore TPS% and look at ETC%

 

OH ****! Sorry for the confusion Yeah, my ETC% is at 100

 

i'm new to hp tuners. Where is that at because I was wondering the same thing?

 

This was something I found on the Ecotec Js too. There seems to be some varience but the max you'll get on ANY Ecotec seems to be 87-91% with the pedal THROUGH the floor. We dyno'd 2 TBs, one with the stop ground down to open to 100% and one stock, and both made the same power. On closer examination we noticed the one ground out to 100% was actually going PAST full open and starting to close back the other way. Not much but it was starting.

Cars like the LSx and LTx and Northstars and all those see 100% though.

Oh and if you look at it with a Tech2...it'll read 100%. That's simply because the Tech2 is designed to read that 87-91% as WOT which equals 100%. We could see it jump from 88-100% on mine, if we watched carefully of course, before with the stock TB without opening the pedal anymore.
