Okay Orgers,

mounted the cam on a custom pod and went ahead and shot this. Trying to shift with a pod in your face made me a little agitated and I mis-shifted
(hence the second part of the video) and a new mounting location. could not do from a dead stop because of traction issues and the camera bouncing everywhere, these are not the best, as in my driving performance, but they will do.

Enjoy!

 

yup it is slow. Its a maxima

 

and you can see the converter lock up in 3rd.

 

have you had any problems with the transmission from using the DR mod? my I35's transmission was slightly slipping when i did that mod, but after using it a few times, it took a crap fast! btw, how much power are you puttin down to the wheels? and which dyno was it on?

 

Mis-shifted an automatic

 

Only way to make it shift faster and rev farther with the dr mod

 

 

If you watch my Safc you can see me feathering all of first.

 

Perkman, it looked like in 3rd at 5k there was a slight hover, or were you feathering at that time. It happens in both takes

 

Bog in powerband = torque converter locking.

 

yes

 

thst is the torq converter locking up, even your car would do that if you had full pressure going through the transmission from gears 1-3.

 

clocks out about 16.1 on the second run and 16.7 in the first right?
i missed the banned run....about what was the timing on that?
i havent played with gate shifting yet...i did a run but ive just tried in d. does it really make a difference in going with gate shifting? cant get the stupid thing to hook up at all...yet...

want to start tuning. considering the afc route...

 

Not exactly 0-100 (when I was still almost stock)...



Wait. This IS the show & tell thread, right?

 

prob, but Im doubting clocking on this video will do much for real times.

Im at 100 in the quarter mile -14.2

 

HELLLL YESSSSS!! Sick

 

I was gonna ask u about that but i figured it was normal...Does it do in when left in D?

 

nope.

 

lol thats why i was asking, traction is moreso an issue in anything other than d so i usually just run from 3 if anything. was curious.

 

Lock up wont occur in D, and with that said the 'lag' will be gone, but it sill shift 'early'.

 

Lock up wount occur at WOT either.

 

Whatever that lag is occurs @ WOT though, and only in 3rd.

 

and im tracking on the raised limiter when gate shifting, but figured without cams the powertrain or cams to capitalize it would be a moot point to do so.
due to fears of the tranny commiting self murder i usually do any runs from a roll and if its one where im concerned about the other car i go from third. realizing the higher revs may help a little i look at an auto as being able to stay pretty consistent just as long as the driver can launch consisitently. didnt really realize it would seriously drop times gate shifting.

 

Buy some 17" wheels already.

 

I gate shift in order to utilize the extended rev limiter, so i see your point.

Also, the tranny fluid temp needs to be at temperature before lock-up occurs (shift to 4th).


I have some dynos and data logs from 4th gens, 5th gens, 5.5 gens and 6th gens that verify that they both exhibit the same behavior in a certain gear. I cannot remember the 6th gen, but the 4th and 5th is 3rd.

 

Needs more tuning! Running too rich or too lean!
Or intake system too long!

 

At 0:35 seconds your SAFC completely drops the RPM signal.

 

Start at 1:30

 

hell to the nah.....spin them heavy *** 19s. All day

 

that happens when i gate shift it.

 

It does not occur in 4th(OD) or 2nd or 1st.

Myself, Jime and Nietzsche have proven this with data logging/capture.

See what happens@ 4.5k?



Here's RPM vs MPH


That's not an intake issue or 'tuning' issue, it's the tranny. The loop occurs because the RPM's subside by a couple or few hundred RPM, that's the reason for the reverse loop. Notice the linear speed curve, this is a 6th gen 3rd gear (5AT), but the 3rd gear in the 5th gen does the same.




Hmm, Ceffy, that’s a good observation. Very interesting. I wonder what that could be. Mine does not do that whether or not I gate shift, and it seems to be only during the shift.

At first I thought maybe it could be the throttle closing during the shift, but it all goes away, RPM and all. Hmm.

 

If I leave it in Drive the SAFC reads all the way to redline. I think it breaks communication with the ecu when I do the manual shift.

something I would have never noticed, as i do not stare art the safc when going wot lol.

could this be because I modulate the pedal during the shift as well? like i get off it then back on it...

 

Why modulate it? Just wondering. But the RPM's die, and the throttle seems to stay at wherever it truly is, as in does not lost signal.

 

and should i immediately shift to d after 1-2 shift.

 

After 2-3. So go from 2 - D. If @ WOT, it will hold 3rd until 6k or whenever the TCM wants to shift (usually @ or around 6k).

 

I want to play......

Not sure if you can see the cluster all to well, but close.

Fresh build, no tune, jumped time 15*, and a couple other codes. Baseline fun run.

 

I love the WOT shifts

 

ugh I hate that i can normally get it to go to 6700 manually.

 

Me too.
