LS3 speed limiter issue

[GPI_Will]

Anyone having trouble with the speed limiter on e38s? We've got a 2010 camaro ls3 pulling throttle and timing at 158mph consistantly on 4th gear pulls. Third gear pulls are fine and we're not hitting the rev limiter and cat protection is disabled. H0129 through H0161 are all maxed out and H0156 is set to ECM. H0132, H0133, and H0134 are all set to no and I'm using v7.5 build 170. Is there anything I'm missing?

Thanks,
Will

If this is the same problem I was having its the Accellerator threshold limiter. My car is at the dyno so I will have the exact parameter next week.

I looked through again and haven't found any additional throttle limiters yet but let me know when you can what you've found. We're still hitting a brick wall at 158mph.

Try setting H0134 to YES

[GPI_Will]

Have tried both yes and no and have tried h0156 as ECM and other module. Also tried pulling the tune with other software and disabling the speed limiter until 7100 RPMs with a parameter that EFILive didn't have. Nothing seems to have helped so far.

Here is a log and the tune for that run just trying to remove the speed limiter. It pulls timing and throttle as soon as it sees 158mph.

ls3 shutdown at frame 1791.tun
ls3 shutdown frame 1791.efi

I've got two seperate 2012 trucks which arent going over 99 mph and the settings are as followed here and many other attempted settings. Is this a known bug?

Same thing just happened to me on the dyno saturday. I was only hitting 6,500rpm at 155mph and bang, no more power. So what is the speed limiter answer? I tried everything I could find. Cam was still pulling. Never got a real peak.

Are they E38's Mike?
As far as I know the speed limiter disable method is still valid on the 2012 models, set H0156 to 'ECM' and adjust the other MPH parameters to suit.
