Speed comparison test on v7 and v8 LMS tune...

[74d34h]

I just got the V8 91 and 93OCT this afternoon. Loaded up 93 and drove for about an hour. I feel a big difference over my previous v6 93OCT. I also do not get the fail to shift 1-2 even leaving on traction control. However, a 1/2 throttle parkway onramp merge threw my CEL. I cleaned my air filter off it was pretty nasty, Ill have to wash and reoil in the next few days see if thats it. The CEL is a pain because it stops remote start from working until I can clear it.

What's the trouble code?

Just updated to v8, I haven't drove it yet, but all you have great things to say about the 3 bar map. I was saving up for the DPs but now I think I am gonna get the 3bar sensor. Then the DPs then meth.

I emailed Anthony but I have 3 DTCs since the V8 93OCT update. My CEL goes on/off daily.

Have you tried to reinstall... don't know your mods or tune tweaks you have to v8... I clear any DTCs with the MyCal just before I start flashing.... and that has only happened when I installed the 3BAR MAP.

Could be a sticking blowoff valve or excessive oil blowby in the system (throttle body/leaky turbo etc).  Changed the oil recently?  What filter are you running?

Dose LMS V8(91,93) tune D mode hold lower gear just like factory S mode? 
(factory S mode give me more fun  but also more engine noise(3000 rpm)  and not good for crusing
when crusing with D mode engine rpm is within 1500~2000rpm   that is very comfortable for me)

what is rpm range of LMS V8 tune when crusing with D mode(under 70mile)
is it significantly higer than factory D mode?(just like factory S mode )( if it is true it is not suitable for daily driving for me..)

Here's what I know... hopefully LMS rep will chime in.

"D" will allow the car to shift to 6th gear , "S" prevents the upshift to 6th gear.... v8 does not affect this.... staying in 5th gear, or any gear up to redline increases noise.  The engine speed at 70mph con be read from your tachometer in any gear/mode chosen.  Redline (about 6200 rpm)is not exceeded by the tune programming. I think this is the answer to all the questions posed.

This is correct, we don't change that portion of the calibration, so D will function like normal, and S will hold a lower gear and be more responsive in downshifting. So, in short, D mode will still bring the RPM lower at cruising speed than S mode.

you can still shift up to 6th in "S" mode with the paddle shifter for cruising. The first time you get it to downshift to a lwoer gear it'll go back to not shifting up past 5th unless again you shift up with the paddle.
