Have anyone notice or know why the tb plate close it self to 35 to 40% at 5000 rpm in 4th gear even if the tpedal is to the floor and the speed limit is set to 150

I think this make the 4th gear wall worst then what already is.

 

slow the F down.

but really that sucks. flashpro?

 

Flashpro and vittune it happend on a dyno day a few weeks ago made 256 hp then did a full speed run and i saw on the datalog
The gaspedal at 100% but tge tb was at 40% the entire time after 5k on 4th gear.

 

I just started tuning my car with flashpro 2 days ago and haven't seen this. The only thing it does that I don't like is between shifts it closes the throttle quite a bit and cuts timing down to -5*. I don't know how to tune some of that out.

 

Vittune is tuning my car take a datalog in 4th gear doing 5000 to 5500 rpm and you will se

 

The only thing I can think of is the speed limiter but you said you raised that, try raising it to 200 and see if that helps because my car doesn't seem to be doing that.

 

Where do you go that you can hit vtec in 4th gear? I've never been able to go past 120 even on an empty highway.

 

The track....

 

Look at this video from the datalog Watch "Acura tl type s auto throtte body close it self at" on YouTube
Acura tl type s auto throtte body close it self at:

 

At what MPH is it? If I had a road long enough I'd try it out and see.

 

Start at 128

 

Def seems like speed limiter. Saw you hit 130mph in video then just wouldn't climb anymore. I would almost set it to something really low to see if that's how the ecu keeps you from going past a certain speed.

 

A buddy of mine was able to push his RSX to 150. Why would the TL do this and not the RSX?
That has to be some sort of governing mechanism.

 

Maybe it has to do with engine load? You don't want to push a car hard (full throttle) in an overdrive gear because it puts a tremendous load on the engine.

 

IIRC, 5AT Type-S (and I'm assuming 07-08 base models as well) are electronically limited to 130 whereas 6MT Type-S and all base model 04-06's (6MT and 5AT) are limited to 155. I know my 04 5AT hit a wall around ~155. Plenty of empty highway around here late at night.

 

Check the limiter settings, that has to be what it is.

 

Even if it's set to higher then 130, I'd still try to lower it to something like 60mph just to see if it's taking that input into account at all. Then during test, does the Throttle plate drop as I hit 60mph.

 

Any update?

 

I haven't use the car i found this on my jpipe and i send it back to heeltoe for repair
