Default Stage 2 WGA vs spring mod.

I just installed the spring mod and found that
VERY interesting,but ,i want to know why
you have to reset the ecu every 2-300 miles?

With the stage 2 WGA you don't have to because the
spring inside is holding the boost right?

So why i have to with an aditional spring that's doing
the same job?

Ineed some light on this.[:I]

Nobody's jumping in here so I'll tell you what I know.

There's no need to reset the ecu every 200-300 miles. I'm not sure where you got that idea. There may be some benifit to disconnecting the battery before a drag race to wipe out the memory if you have been logging a lot of slow take-offs with "lazy" shifting.

The ecu (PCM) will learn your driving style and adjust to it over time. Disconnecting the battery gets rid of any cobwebs in there. Some of us think that a lot of the reports of "improvements" after a modification could simply be due to the battery disconnect. That would explain some of the "Wow, is my Cruiser fast now" reports but after things settle down, not getting faster times at the drag strip.

You could be setting off a CEL code. More than likely it is the part throttle boost code. Let me know what code you get next time the check engine light turns on. If you are spiking boost too high then the ecu is pulling timing and that would also explain the sluggishness.

I read it in an SRT forum to disconnect the battery
because the 'computer compensate for the higher/faster
boost'.I did not understand why the S2 WGA was OK and
the spring mod was not.

By the way,i'm spiking 15lb up from 12 stock and holding
8 lb almost to redline.I'M very impressed whit the result
of my 4$

Can't wait for my S1...[8)]

turbotouring, do you have the stage 1 pcm installed? If not, then you will be pulling codes for part throttle boost or overboost. Any increase over the stock levels will create codes in the stock PCM over time. Since S1 isn't out yet for 05's, I get codes pretty often using a boost controller set at 15psi on mine.

You have to do the EDTIP mod if you're going to be upping the boost so you don't get any CEL's.

I have tried what I think is the EDTIP but it doesn't help. The PCM gets wise after about 20 miles. I disconnected the vac line running from the UCP to TIP sil. and unplugged the vac line into the TIP sensor. Is this the correct way to do it? If it is, then DC programmed the 05 PCM to detect it and throw a code. I have even tried using stock boost and EDTIP and got the same results. Did this just to see if the PCM recongnized the dissconnected sil and sensor lines and it did throw a code. Any thoughts... Sorry to thread jack.

Naw buddy, close but not exact! Disconnect the vac line from the UCP and stuff a heavy ball bearing into it so no air can get into it, and the vac will seal it further by sucking it in. The trick is to not let the TIP sensor get any pressure reading. Then put a cap on the UCP where you took off the vac line and use a tie wrap, zip tie, whatever you want to call it, to hold it in and not get blown out by the pressure. Make sure you disconnect the battery when you do so, so you can reset the PCM. Let me know how it works out for you.
