Vitesse II Turbo Boost Curve
#31
I have no idea, have not been to a dyno yet. But based on collective net wisdom, my +90% duty cycle, 55# injectors, 12.5:1 AFR and a T04E running at 18psi, I am hoping it will be in the 350rwhp range. But, thats all talk until I can get to a dyno.
On the street it feels strong, especially in cold weather, it pulls like a raped ape in 4th gear at anything over 2800rpm. 3rd gear runs to the redline are a trip. I walked away from a vette today in 5th gear from 70mph.

Your 55lbs will be running out for sure at 350. No ones likes running injectors in the 90's. The dyno made a HUGE difference for me. Drivability went up 10 fold. My tuning was ****. Much better at it now though. Waht do you reckon for these 850cc's? Just lower the master down and keep all the values?
#33
Yeah, lowering the master should work and get you close. You should get a wideband and feed it into the Link, its like having a dyno whever you want. I can do a run, come back and see where my fuel curve is and then try suble changes, not only at WOT but anywhere. Now I have a nice 15:1 on very light cruise, 13:1 on moderate accel and 12.5:1 at WOT.
Its interesting that both our fuel maps are very similar apart from the master and slightly different high end values.

I have not seen yours yet bastard hiding it from me!!! Only the timing one ages ago. What WB did you use? with 1-5v 20-1 to 10-1 linear type? How does it hook up? There are extra wire with WB yeah? I have the link AF gauge, it rocks my world so bad.
#36
Envy! Those are some sweet standalone setups. I would love to do that.
Does anybody know why MAP with the Link 2 standalone appears to be great, yet the MAP with the Link piggyback introduces all sorts of driveability issues? Is it a resolution issue? Is it the sensor? Sorry if this is rehash, just let me know and I will search.

I use a PLX wideband, its 0-5v but has an add on module that inverts and scales to 0-1v.

No need. The PLX has a built in display and the ability to drive 0-5v WB displays or data log input. WB reads 5v as lean and 0v as rich. The adapter inverts and scales so that I can get a linear, proportional 0-1v output. Now I can drive a normal O2 display and have is display WB. Look at PLXdevices.com.
Now the trick part. I have a dual rocker switch panel, One switch tells my Autometer display wheather to display NB oe WB, and one tells my Link wheather to log WB or NB...total flexibility
i.e. I can have the link logging WB, be looking at the equivelent NB and have the PLX displaying the actual WB...

I searched but could not find any detailed info on the Home Depot mbc that Jeremy mentioned. I'm pretty sure it must be a ball and spring check valve (like the famous Grainger valve) but I'm not sure where to look or what to ask for. What PSI range do I ask for?
Sorry to jump in so late on the thread.
