T3?

What MAP sensor are you using?

Marti, that second pic you put up in post #23, is that turbine housing the .70 a/r T3 housing?

Thanks,
Gary

Gary,

Yes, that is the .70 V Band housing. It's my personal favorite for the BW line. We've made awesome power on that setup. We have yet to hit less than 450awhp on pump with any of the 256 builds we've done with it.

sorry guys i got a new laptop and was going out to tune and the new laptop didnt have a driver installed for the keyspan adapter and bla bla bla, woudnt connect, so tuning went on a pause.

I should have some logs to post up soon as soon as i get that figured out.

I did do another pull in 2nd gear after adding some nos octane booster and fixing my Cold Air Intake elbow and the wideband now reads RICH throughout the pull, so im running in the 9:1 a/f ratio, which needs to get fixed very soon.

My car had a fit the other night when i was driving home from the bar, it wouldnt want to stay alive, but since i was in gear going downhill it was kind of sputtering and still driving kind of when i was off the gas, but the second i pressed the gas it would sputter and almost die, but the rpm would hover right around 2k...? Then i got to the bottom of the hill and it died, i tried to start it a few times and it would crank fine but it seemed like it didnt have fuel, so i checked fuses and connnections, cussed at the car a bit and then decided to push the car (which was a bi*** with a welded diff and the fact that it was in a parking spot), so i got it out of the spot, pushed it like 50 yards and down another small hill, tried to pop start it in 2nd gear, it would kind of catch but do the same thing it did while going down the other hill, so i parked it again, cussed some more, then i just took off the negative battery terminal to reset the ecu. Waited like 5 minutes, neg. cable went back on and the car fired right up, drove home, then i turned it of and back on a few times and it started every time. Totally wierd eh? Oh well its a DSM it has to throw a fit every once in a while.

So im going to get my car to connect to my laptop, tune fuel trims, make sure everything is cool and the car isnt going to act wierd again, then i'll go out and do some tuning. Hopefully i'll get my a/f ratio in line first, then try to either crank up the boost with the timing as is or bump up the timing and eventually turn up the boost, or both!!!

Look forward to some #'s.

Damn danny, pushing a car in frisco holy shit.

 

[T9S1i]

haha, tell me about it! At one point it was rolling backwards into me and my girlfriend (5' 95lbs) couldnt pull up the damn e-brake... she got an earful quick!

 

[chavez408]

I do feel sorry for our gf's sometimes. One time I was pushing my car up a somewhat hill into a parking lot. She was in the driver seat and she pulls the darn ebrake right on the top of the hill before entering the parking lot. Oh man I was pissed. I didn't have any strenght to push the damn thing in there, it kept rolling back. That is when two old guys (50 and up) gaved me a hand. It was pretty funny. I need a daily driver.

 

[T9S1i]

haha, ive got a daily driver, i think its a must with a DSM

For a while I didnt though, and I had to run my car on 10psi and drive carefully so that I wouldnt break anything
