Thanks! Glad to see you on the boards every now and again. I can't make the BBQ meet b/c of work, but I definitely see some meet in the near future!

I assume the dips in PSI are b/c of in-between shifts? I am actually surprised I didn't encouter faulty DV problems like eugen. Good job shiv

.

You think I still have room to up the torque a bit?

That's really about it.

I am not experiencing any throttle problems. I just notice the boost is a TOUCH more eradict when datalogged when @ 93% as opposed to 92%, but the pull is still linear and amazing

The extra bumps in boost were between the shifts (when the rpm was dropping). So you can ignore this as the throttle is closed. I have yet to personally see a leaky factory bypass valve myself (I've pressure tested mine) but I wouldn't be surprised if there are some out there.

I figured it was as such. I am actually quite proud of my smooth boost curves, but what I find weird is my max PSI hasn't changed inbetween changes in 91%, 92%, and 93%. It is always around 14.4 14.6. I guess I will have to increase to 94% tomorrow and log it

Hey dude, glad you are enjoying your new v2.
Again, sorry it took a few extra days to get.

Have fun.

MBMWTECH · 01-07-2008, 11:44 AM

I've got mine at 96% Max boost i have seen is 15.1 psi.
93 octane
I miss the power down low before v2 though - the boost change on v2 is going to take time to get used to.

if your at 96% you should be feeling similar torque down low!

The car feels totally different to me - Im def. not getting the torque i was before i upgraded to the lastest firmware the low end torque is ok but all the midrange torque has seemed to vanish (im only hitting about 12 psi of boost at full throttle from 80 mph) - overall Im not 100% satisified with v2 (I was more happy with my original firmware & map when i first loaded v2)
I always had full boost anytime I wanted. I generally dont floor it from a start - the boost is there down low but not there under full throttle @ highway cruise speeds like it was before the pro01v03 beta - I do 80% highway driving

When you can, post a couple datalogs of a 3rd gear pull from 2000rpm to redline. Then a couple of 2nd to 3rd to 4th gear runs. It'll help us see what you are seeing. If you can do this with user torque set to 94%, that would be good.

I will try - I have been having a problem with my laptop ( its got vista)
and occasionally drops the connection so its hard to stay connected for a long time.

Another Update: Did 2 runs on 94% and peak boost is still 14.4 - 14.6 PSI. Got my adaptations cleared and it is like v1.47 power distributed throughout the entire powerband! A lot more fun now than it was before clearing adaptations!

That boost level is perfect too me.
Not pushing the maximum envelope of 15 psi, but close.
Good strong level you are at.

BTW, what do you mean by "a lot more fun now than it was before clearing adaptations"???

It feels like that punch of power the v1.47 delivers. Only now it delivers throughout the powerband with no cut off in sight

.

Also, I was wondering, since my datalogged peak PSI is 14.6 PSI, i there still more wiggle room? I have seen 14.6 peak ever since 92%, then 93%, and now into 94%? Is this a leak, incorrect datalogging or what? Or is it that my car can handle more?

I still don't know what you mean when you say you "got your adaptations cleared."??

What did you do to "clear your adaptations" that made your car feel stronger?

As for wiggle room with the boost percentage.
I would say you are close to being as high as you want to go.
If you are peaking at 14.6 psi (when accelerating, not a brief little common boost spike when you lift off the throttle) you are near the 15 psi limit.
You could raise the percentage to like 94.7xxx% and see what it does.

But keep in mind, you are in the nice cold winter months right now.
When summer comes you might be pushing the limits too much then.

I'm seeing peak boost of 14.4 psi occasionally and that's usually for a tiny little bit (like 100 rpms).
Most of the time the peak is at 14.2 psi.

I'm running 91 Octane though, and so that's enough for me in the cold weather, figuring in the heat of summer, I don't want any CEL's or codes from heat/boost related issues.

Since you are on 93 Octane, I'd say 14.6 psi peak is on the safe side and again, try 94.7 or 94.8% and see if you peak at 14.8 psi.
If so, and you are like me and want to be a smidge conservative and safe, I'd leave that as your limit.

My car is also showing the same peak boost at 14.7 at 93%, 94% and 95%!!!
I don't understand why the peak numbers are not going up either??

I wonder if it has something to do with the converting of PSI to voltage and then the reading of the votage and then determining PSI via the datalogs? Maybe I really should invest in a boost gauge *sigh*.

I wouldn't worry about it if the rest of your car is stock.
15 psi is reportedly the highest you can safely (according to Shiv) go on pump gas.
You may be limited from your intake too.
Without enough air coming in you may never see any higher than 14.7 psi.

But don't be too eager for the quest of 15 psi.
The difference in power between 14.7 psi and 15 psi will be about 3-4 rwhp.
1 psi boost increase seems to equate to about 10-15 rwhp increase.

When I initially installed my v2 and then first dynoed it, the difference in power between the default 90.1xxx% settings and 92.1xxx% was like 9 rwhp. I think the datalog boost gauge showed a difference of 13.8 psi peak and 14.1-14.2 psi peak going from default to 92.1xxx%
