Spike!!!!!!!!!!!!!!!!!!!!

[toaofallen]

ok these are the modes i have cobb sri blitz turbo timer and a boost gauge.
i was on the high way yesterday and in 6th gear when i floored it the boost was spiking 15-18 repetitively. so i went thoue the gears and it only dose it in 5th and 6th
and ideas as to what can be doing this

Stock boost is 17.4 i believe so 18 is not that much. I run 18 psi. Probably just the right conditions cool ambient temp, highway speeds=cool air and tmic cool. 5&6th cause 1-2 nd gear boost is limited. As long as your not getting any fuel cut your fine.

 

[scatt nasty]

LOL I was hoping to see a banhammer being that your thread title is SPIK ! racial slurs ftmfw..

STOCK boost is 15.6 thx.

 

[mr_mazda329]

wow...spiking with stock BPV?

 

[toaofallen]

ya i cant spell and thats not a joke i relly cant
but its not like it will hit 18 and then go to normal boost it will bounce between 15 and 18
no chekengin light has ben thrown and no flue cut should i be worried

 

[clos561]

proly ur gauge

 

[toaofallen]

no i can definitely feel the spike<---(right)

 

[clos561]

ok so it hits 18psi then flutters, does the car stumble/jerk when you see the gauge doing this?

 

[toaofallen]

ok when i hit the gas the gauge will bounce between 15-and 18 psi and when it dose this the car will jerk (kind of )

 

[toaofallen]

ok well i just went to the mall and evrything seams a ok now

I think I can relate

Toaofallen, I think I can relate to your problem. I don't have a way of monitoring boost yet (my dashhawk is coming this week), but I can tell from my butt dyno that my car is doing the same thing. It all started for me when I installed a corksport turbo inlet pipe and intake. I heard from some people on here that after you reset your ecu you have to baby the car for the first hundred miles. When I did mine I didn't really follow that, I had my buddies with me so I was getting on it every chance I got so we could hear the turbo. Something tells me that by doing that my ecu learned incorrect fuel/boost/whatever else, so in hight gears such 5th and 6th it spikes all the time. This is actually the reason I bought the Dashhawk, so I can see if my car is running right.
I could be very wrong about my assumption, it's my first turbo car, so I learn as I go. Please somebody with knowledge about what it could be chime in.

A wee bit off topic.. How important is it to baby the car after ecu reset? For how long? By babying the car, how slow or what rpm are we talking?

that sounds like it could be it i hade to reset my ecu fore a chekengin light(acsidently fill up with the car) so i disconnected my battery and whatid a bit but that was like 3 weeks to a month ago

After you did that, did you drive like a granny for the next hundred miles or no? I didn't and that's why I think my car does that.

stan, i think that is just a myth. any bolt on part should instantly adjust as long as you reset the ecu. any mod ive ever done to any car or any friends car we got on it and pushed it hard right away and no CEL/no problems. i mean, what if the part you got was faulty, makes a sound you dont like, or doesnt perform to your expectations at full throttle. do you really want to wait a couple hundred miles to find that out? when you get your dashawk monitor your fuel trims and AFR you should be ok. they even say something similar about when you buy a vtec car brand new that you shouldnt engage in vtec untill you hit 500 miles and i think thats bs.

Even if your spiking to 18psi your fine. I was running 21psi on the stock turbo and internals fine.

Lol! normal with a intake. i have a cold air n spike 20 on cold nights at the everglades in south florida. Boost controller or cobb will fix that. sometimes i also run into boost cut. Anddddddd i manage to run into a bit of boost creep in 5th gear WOT wit will go as far as 17-19 pounds b4 its cut. buh im (hear ya)

 

[toaofallen]

ya a freind of mine who owns an ms3 said thats to be exspectid he said a simple (map clamp)???? will fix this

You don't necessarily have to baby it per se but it's good to vary the engine load and RPM's while the ECU is re-learning. For me, it typically takes about 3 days (6 driving cycles @ ~10 miles each) for the fuel trims to stabilize.
