TurboXS downpipe & New UniChip program

phooka · 11-30-2001, 05:42 PM

I installed the remainder of my TurboXS exhaust yesterday.. shaaaweet! Downpipe, replacement cat and midpipe. Not much louder, but has an interesting 'whistle' sound to it now.. sound very cool. Turbo spool up is much sooner now and boost comes on quicker.

I had a slight fitment problem with it though. I am forwarding pictures of the issue to Mark@TurboXS. They have installed this exhaust on three cars and I'm the first to have a problem with it though. My fix was pretty easy though.

I also have his new stage 2 program for the UniChip I received today.. This is a new program as of Wednesday. I haven't driven it yet to test, going to do that shortly. The new program uses the stock restrictor hose instead of the blue one provided. It should help contain boost spikes, and help me keep my EGTs down. I had been seeing peaks as high as 1700 (ow ow ow)..

I'll report back later!

Stage 2 does that mean you have the upgraded intercooler and water spray kit

hkwan · 11-30-2001, 07:22 PM

Would you let me know what the peak boost is? Also, what has changed to the program that allows the stock tubing to be used?

moebiusone · 11-30-2001, 07:27 PM

A bit off subject, but for the spikes , would it go away if you added the unichip boost controller to the unichip ??
How does cobb do his tuning, since he kepts the same restrictor ?
And can't Marc use the same restrictor and increase boost anyway ??
thanks

moe. - look in the post titled "Boost with Unichip" or various posts has the Unichip title in this forum. Wealth of info. on the topic, no need to reiterate it here.

I do not have the upgraded intercooler, yet. I have the complete turboxs exhaust, and the chip - that's it. I'm just going by what was printed on the chip this time.

The boost is down to about 16.5 now (where it should have been anyway).. I had seen peaks regularly in the 19psi range, with surges to 20+. I am not seeing anymore spiking at all, my EGTs are way down, psi is stable at 16.5 adn drops off as rpm increases - it's all working perfectly. And no less power than I had before (per the seat of my pants). I'm very happy at this point.

I'm not entirely sure what the programming changes were, but I like this - less psi and lower egt's = longer engine life.

I don't know if this is Stage 2 or if your new program is actually similar to the "fix" from T.XS that have been talked about. I believe you new program is very similar to CA's Unichip program. Phil has told me that the CA chips have been shipping out with the newer, less boost program. Forgot what he said about the timing for the chip though.

phxscooby101 · 11-30-2001, 10:18 PM

Phooka what is your boost now at from 5k to redline, compared
to other program? because i'll be gettin my stage 2 pretty soon.

i personnally want more boost since i got uppipe, m2 intercooler,
intake, full turbo back exhaust my system is beggin for more
boost it already will spike to almost 15psi with all stock ecu
controls, except for above 5k rpms. later

GCSUPRAMAN · 11-30-2001, 10:21 PM

Could you please elaborate on your fitment issues...i have a DP on order and would like to know :-)

Thanks

Greg

I guess we'll have to call Mark and Phil to find out if the "fix" is in and how to get the reprogrammed/no spike chip.

Anyone find out yet?

I haven't had a chance to do any qualitative testing yet - I just got the new program installed last night. I may not get much of a chance this weekened either because I get my kids this weekend. So far though I have not see any boost beyond 16.5psi - before I could easily hit 20 whenever I wanted.

How does the m2 intercooler compare to the stock one? I have looked at that one for a while now as a replacement option.

anyone know if the down and mid pipe would work on an auto wagon? are they the same?

Phooka it's way better than stock one hoses are that samco kind
and bigger. when it was about 85 here not to long ago it was
alot more resistant to heat soak , i think its from the bar and plate
design. if you sit for like 15 to 20min it will warm up but it cools
off fast and stays cooler longer. i might get the auto waterspray kit later next year before it hits 100+ degrees anyway and since
we get the crap gas here to.

i think the fmi would be good but its 500 more and those long
metal intercooler pipes will get hella hot . i've already wrapped
my injen intake with turbo wrap it helps alot, to keep it somewhat
less prone to heatsoak. later

what's your boost at redline in the lower gears? later
