Yes! Do a 3rd gear WOT log from 2.5K rpm to rev limiter ~7.1K and email it to me at thormix@pacbell.net

I will take a look and make adjustment to your XPT GM BCS map, if needed.
Make sure to log all the good stuff. Boost, Timing, Engine load, etc etc.

Gotcha. I still haven't installed the BCS or bought the XPT map yet. I've got other priorities but I'll email it once I do it.

Cool. Your going to love the XPT map & the GM BCS!
It's defiantly a winning combo.

Can't wait! Just installed new clutch, light flywheel last weekend so I've got another 700 miles of break-in on it. After that I'll throw the BCS and XPT map on. I'm still having trouble timing shifting with the new clutch; I've got to let off the clutch earlier than I used to, while giving gas at the same time as before since the flywheel drops revs so much faster.

You do not need to add the 20ohm resistor. The XPT map deletes that CEL code when you flash the map to your ECU.

Enjoy your XPT Power
what size hoses should i buy? brand? type? im on rockauto right now, about to purchase the BCS and pigtail. tia

5/32" . Just get it at your local NAPA or other parts store. I typically buy 6 ft and have a little left over.

^^^ What he said

Take a piece of your existing hose to the Parts Supply store (if you can) and match it up for inner wall size.

If anyone needs a GM BCS pigtail I've got a few here that I bought too many of. $15 shipped.

I'm still having a hell of a time controlling boost spikes.

It's on the range of almost 3psi !

I'm using utec on an 04.
Ive had my boost gain from 55 - 85 ! And change my boost map accordingly to keep boost under 18psi

At first I had no restrictor, very unstable boost and spikes.

Put in restrictor, less instability, still spiking pretty badly.

I'm using smaller than usual vacuum tube, it was a real pita to fit it over the compressor outlet and solenoid.
Could this be a problem?

I also have it making a 180 degree turn right before it hits the solenoid, but its very long and smooth, no kinks.

The 10ohm resistor has nothing to do with performance right? Just a safety precaution?

Don't know what to do next, Any advice?

Here is a small log showing the spike.

Damn noone checks this post anymore eh?

This is still pissin' me off

Spike's are down to about 2psi, but boost wavers a good +- 2psi also.

Don't know what to do.

Switch to PID boost control, as found in the newest firmware. Start with a VERY LOW gain, like 10 or less, along with a low/safe WG duty map. Note what the UTEC *tries* to run for WG duty versus what's in your map, and compare actual boost versus target boost.... make your changes from there.

I don't know why anyone would bother to still run the old stuff.

Old stuff as in stock stuff, or something different? Not everyone uses a UTEC...

Old stuff as in old UTEC firmware. The post above mine is from a UTEC user... the same one that posted a UTEC log 5 posts up. I was trying to help him out.

I was reading up on PID boost control.

So target boost is based on rpm?

I don't know it just doesn't seem like a good solution.

Mick's guide says its rock solid once tuned, but boost is not based on TPS anymore.

Maybe I'll play with it one day.

As far as I know, the boost map has always been RPM vs TPS. Even now, if you don't want full boost at part-throttle, then leave "ECU" in the boost map, up until when you have the UTEC take over (typically @ 30%).

The PID control is less sensitive to changes in weather. It's supposed to be the same logic that is in their standalone DTEC-BC boost controller.

So between 30% and 100%, what is the boost target?

Mick's guide says the 0% column is the boost target for that rpm range regardless of TPS.

Then the TPS% is the starting gain value or something.

What If I'm at 5k rpm, at 60% throttle in a constant radius turn, will it aim for 18psi( or whatever max is) ?

With UTEC PID the boost target is always what you put in the far left column, unless you put in "ECU" in the 10-100% column. So whats up PTFB.

I think it is funny. Did this mod lowered my WGDC by 30% couldn't hit more than 12 psi. Went back to my previous map and there were no problems. This had no effect in WGDC. It only stabilized my boost which isn't bad just wasn't the only help I was hoping for.

HAHA I like how if it doesn't work for some people then it's broken or junk...

How about if it doesn't work you're doing it wrong.

Wow that is a funny statement. I don't recall ever saying it was junk, broken, or a waste of money. If I look at my post I did say it stabilized my boost which yes is a big help. I no longer ever go over my target of 18 psi, in fact in 3 hours of logging the highest PSI of boost recorded was 17.99 psi which compared to the stock BCS highest was 19.17 psi.

As well what an informative post of possible issues I should look into for the reason I need no change in WGDC.

That's why you should taper the WGD down from the 90-100% columns, and not use a huge gain value. That way, the UTEC simply won't have the authority to hit full boost at part-throttle.

for anyone looking into this here is a graph showing the improved spool with the GM BCS


three setups were
stock BCS + free XPT stage 2 map
GM BCS + Ziggy's free stage 2 map
GM BCS + $77 XPT map

this is 3rd gear WOT

-Rene
so is this "normal?"
I've been reading everywhere that I need to drop WG, but my case has been exactly the opposite...

top - initial and max WG STOCK
bottom - initial and max WG ADJUSTED for Prodrive 3 port






when left at stock WG map, the boost was only able to climb to 14psi!

I also used hoses from the stock solenoid

I got the unit (prodrive 3 port) used from a fellow member, could it be faulty? If it was, would it be boosting at all?
