sometimes 2nd bogs? i have been running ET streets on the street a couple times now. Sometimes when i punch it about 30ish it hits first and then on the shift it almost feels as though the converter locks up 2nd <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> . it bogs pretty bad- but the rpms are high above 4K- might have been ~5K
do you think its because the Et streets are a little taller than stock (26x10.5s-16), or that it just hooks on the shift and doesnt know what to do? im puzzled, as it doesnt seem to do it all the time, just ocasionally- usually when im racing someone <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" /> . never had that problem with the 315 nittos <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> stall is a vig3200. any ideas would be great <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: sometimes 2nd bogs? It's TM, I had the same problem only with the 2-3 shift after having TM removed. There's more to TM with the 01's and your programmer probably missed something (mine did the first time).
Tell me if this sounds familiar, wide open throttle burst the car shifts normally then the rpm's fall to 4500rpm and won't rev and higher unless you pedal it or let of.
That's what mine did and TM was the culprit.
AutoTap a pass and I bet both fuel and timing are being pulled.

Re: sometimes 2nd bogs? really? Im sending the PCM back tomorrow to get the timing fixed in the first place. its about 23 degrees. i wonder if the low timing would have anything to do with it. its kind of wierd because it only does it sometimes.
ohhhhhhhhhh, which reminds me to remove HPP3- bumped the shift pressure up. good thing i remember. i forgot the first time <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: sometimes 2nd bogs? ive done some highway a-taps where it went from 2-3 and it seemed fine <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
but ive only put maybe 500 miles on the new tuning cause its so crappy out. timing seemed to be about 23 the max at WOT.
*who did your tuning reboot?

I had John at Speartech do my pcm (great guy to deal with). I think that the 01's TM system is more complex than previous years and requires addition parameters to be changed vs. the 2000 and earlier f-body's.
BTW- I only have between 23-25 max timing, but I never asked for that to be changed because the car currently is making good power 362RWHP 373RWTQ and I don't want to play trial and error with a mail order pcm. I'll wait for LS1 Edit and tune on a dyno.
Good Luck

Re: sometimes 2nd bogs? 23-25? do you think you will see more out of the car if you get the timing in a more acceptable range?
right now i dont think ive even seen 25 yet. i used to have 29/30 before tuning. it was near perfect.

Re: sometimes 2nd bogs? it is an 01- no TM as it has been programmed out of there.
the bog is consistant too- its not on the shift alone. it seems to bog till i let off the gas. i havent shifted into 3rd with it like that.
no shift kit either.
im hoping its just the tire height and not the tranny breaking. 5K miles on the tranny. with a new pump about 3K ago (long story <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> )

Re: sometimes 2nd bogs? it feels almost exactly like when you lock up the converter as soon as you shift into 3rd and it bogs down the motor and feels like you arent moving- even though the rpms are way high.
im not sure why the converter would be locking up into 2nd though <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: sometimes 2nd bogs? I have a 2002 WS6 TA/A4 and did a half dozen runs a couple of weeks ago and noticed the dreaded 2nd BOG as well. First run, lots of tire spin in 1st then second and bog,picked up later in the gear. Second run same as first but feathered petal once it bogged in second and got like a gear kick down??? and it picked up(couldn't be jumpin from first to third with all the tire spin???)Third run I squeezed the pedal from the start with less tire spin and the bog wasn't there. Totally confused, is it TC,TM what the hell??? One thing is for sure I not thrilled <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

Re: sometimes 2nd bogs? I still have TM with only 1200 km on the car. The only reason I say that it may have jumped to third is the tires were still spinning when the 1-2 change happened and when I pumped the petal when it went flat I got a definate passing gear type hit( and it didn't jump back to first... revs weren't that high)
No matter what the situation IT MUST GO!!!!!
