LT1 : Throttle area limits, Max% Area vs RPM impact on torque

[Sachs]

Guys,

I have a question about this parameter.

From the factory

800 rpm 1200 rpm 1600 rpm 2000 rpm 2400 rpm 2800 rpm 3200 rpm

22.9% 28.30% 39.00% 43.40% 53.00% 60% 100%

My question are :

- Does it change the torque at low rpm to put 100% sooner
- Was the point of GM limiting the lugging on the engine at low rpm ?
- If it changes the torque at low rpm do you think there is a risk for the motor (too low oil pressure for the torque)

I saw some people put 100% everywhere, wanted to see if it is fine before trying... Does it require to change torque management ?

Thanks

I've tried both 100% in all cells and stock. I prefer the stock settings personally. If you're drag racing then setting everything to 100% would likely benefit the launch. Otherwise I saw no need for it. I never noticed a need to change any torque settings for it either. My thoughts are on the highway at 80mph at 1800 RPM in 7th gear, if I push the throttle down halfway it would lug the engine too much. By setting the throttle limits back to stock, I don't feel the lugging on anymore and don't have to down shift.

Mine are all at 100% and I have no issues being an automatic. I have set them this way in 7 speeds but never noticed it,mainly because no one has complained, but that doesn?t mean the lugging is not there. It likely is, and I never gave it much thought. I was just happy to get rid of the horrible throttle lag down low.

My 2016 Camaro had everything 100% stock and others including a 2018 ZL1/1LE stock are the same.

I think the manuals may be the only ones that have them not at 100%

Maybe not appropriate in the Gen5 section, but I have a Gen4 Yukon and it was 1% at 800 rpm, 50% at 1200 rpm, the rest 100%. First time I drove it pissed me off in parking lot maneuvers. Stepping on the throttle lightly and literally nothing happened. They're all at 100% now. I like using my right foot to control the throttle.

Any Idea why they wouldn't? My Manual stock was not set to 100% in the low area's but now after the dyno tune it is. I am trying to better understand how this table affects throttle response.

Because say you are in a manual and driving in 7th gear on the highway at 1800 rpms. and you press on the throttle to pass someone while leaving in 6th or 7th gear. You don't want the throttle blade to open all of the way and lug the engine because high load high gear is much more prone to spark knock. If you were in an auto and did the same thing the transmission would automatically downshift to the appropriate gear. This is why the manuals are set this way.

on 2014 6.2 GMC denali

what if i kept all the table at 200% what will happen

knowing that the stock file had the whole table at 100%

does this makes sense?

There will be no difference.
