This thing is a real sleeper. I can't wait to come across a mustang or vette and have some fun with them.

I didn't get a chance to drive it with the BSR tune installed but I can say that Bills tune is super smooth and it runs perfect. I am really glad that I live in the country and have a lot of back roads to play on because this thing is a blast to run throu the gears.


I made a small video of the car at idle and a few revs. and sent it to Bill. I am on dialup and it takes for ever to send anything by email. Hopefully it goes through and he will post it so you guys can hear the exhaust. I can't put into words how great it sounds.


Thanks again to Bill for more great HP!!! You rock.

 

Track times. :)

 

Bill, how much is this kit?

 

Yikes! As if hosting and posting four separate graphs wasn't enough
But very observant nonetheless. XXL gets the prize for paying attention!

In this case, the smoothing approach was appropriate for each instance. When major oscilallations are present, we choose the largest smoothing factor for the most accurate depiction, thus avoiding unrealistically optimistic "peak" readings. When oscillation is minimal, we choose minimal smoothing.

What can cause such oscillation? Many factors, including vehicle movement on the dyno, a boost level 'hunting', A/F ratio adaptive behavior....or combinations of all of these. In the case of the PPC Tuner, we did less runs overall, for there was no opportunity to tailor the tune as there was with the custom tuning. Had we made as many pulls with the PPC, I daresay the oscillations would have become markedly less apparent (if not disappear altogether) as the adaptive behavior applies itself.

 

Pricing is about to be released with the new products themselves. I will also PM you on this. Thanks!

 

I get a prize?

So, wrt the hunting that the BSR is doing, you believe the ECM would learn down some of that behavior? In essence, the 'learn down' behavior of the ECM is to pull back the gains that are "out of range" from what it expects. If the BSR tune has not bypassed this functionality, how does the tune get away from existing at all? ie... not getting learned down altogether?

Also, my first impression re the hunting was that the stock BOV is not holding up its end of the bargain, but since it's not apparent on the Hahn-tuned curve, I'm guessing that's not a (significant) problem for you (I can hear the hunt on my BSR-based system quite often at steady "too fast" highway speeds...).

 

Not the 'learn down' function involved here, but the fuel mixture/timing/boost control systems and how they interact in concert with one another. We've seen these behaviors subside over time. I'd like to inquire on your particular experience in greater detail, however...I will PM you and mine data. Thanks!

 

Dayum i'm impressed It was the middle of Summer in Florida when i had my vette on the Dyno.Maybe that's why i pulled such low numbers.

 

Have pretty much the same setup (Hahn full 3" system, IC, IC pipes, Hahn/PPC tune), and have noticed that if I do a long pull in 5th gear at steady 20/23 psi boost on a cool day I will sometimes throw an "overboost code" and lose all boost. All I have to do is clear the code, and it all works fine again. Only happens in 4th or 5th i.e rare occurrence. Anyone else ever get an "overboost" code P0234 ?

 

not yet. thanks for the heads up!!! i have the same engine mods as well. thought about adding mr9(just a little lol) i know this adds a few hp to my bike(10). what do you think??
