This is annoying the **** out of me! It seems like it pulls really hard up until 95, then it slacks off and eases up to 100 where it stops pulling completely.

Every mod I have done yielded almost no increase mph on a strip I use to test. It seems everytime I run it I get to 95 and it starts falling down.

Has anyone else experienced this? Is it a new 'feature' where it hits the speed limiter soft instead of hitting it and cutting out? I hope EDIT will let me take this 'soft' limiter off or at least raise it up a bit. Does anyone have any info on this?

Yeah, thats the speed limiter, any good programmer should let you remove it or move it up to match what tires you're running.

Do you get the same soft approach like thing I'm talking about at 95? Any idea on what it's doing to achieve this? I tried to log it the other day when I was running EFILive, but I couldn't get a stretch of road to run up to 100 safely.

It did, my limiter is at 110 now to match my shitty goodyears, it still cuts out the same though. (edit- starts cutting out just before 110 mph IIRC) I don't know how it cuts it out. I wonder though if it doesn't just ease back on the throttle, since its an electronic throttle.

Yours still cits back at 95? That is gonna be so frusterating!

That's a good thought .. lemmie check some logs.

That's it .. throttle is pulled back to about 58% and gradually backs off as it approaches 100.

It still shows to be in PE mode judging by the STFT's and the 02 readings.

On a side note .. I'm getting -10 degrees timing when it shifts. Wonder how much that kills performance?

That -10 is torque management, plain and simple.

The new electronic throttle is the speed limiter. No more cutting off fuel, it just automatically eases off the throttle, keeping you at a nice solid 95, but no more.

I moved mine up to 145 with LS1 edit, but I haven't tested it out.
