got my WRX back today a few quick questions.

[Guest]

Hi .

so i got my beloved WRX (1996) back today from an brake upgrade (for trackdays) and also fixed the one boost pipe . (it was too close to the fan cowling and managed to rub against it finally chafing thru)

now my question is this ... since i got it back my rexie sounds different ,it seems to not dump as loudly as before and also the turbo "whoose/whine" seems more pronounced .. now nothing was changed or modified , can the repair of the pipe make a difference to the sound of the motor ? it does seem to run a fair bit better than before thou .

also , the check engine light comes on and goes off randomly , i had the mechanic pull the codes and there is NO error code . also when getting it from the selfdiag there is nothing . Is this something i should be concerned about ?

thanks for any help !

Regards

Rudi

Is it running an aftermarket ECU? SOme ecu's can be programmed to use the CEL as a knock indicator?

[Guest]

no it is running the stock ECU ,has a gizzmodo boost controller but only running standard boost .

the engine light comes on even when pulling away in town at low rpm (randomly) and sometimes under mild acceleration ...just took it for a drive again and it did not come on at all ...weird .

how long was it sitting from breakage to first drive?

hi .

ok did a bit of fiddling under the bonnet .. (never a good thing when IT people touch mechanical stuff :-P ) but i found that the rubber pipe from the BOV was slightly bent so i straightened it and it seems to be a happy dumper again !

Also the motor was rebuilt about 7K ago by the previous owner and i had a look and boost is set to 8PSI (wel that is where the needle stops on the boost gauge) . At what stage is it safe to raise this ? Is 7K enough running in kilos? Please also correct me if i am wrong but standard boost is 10 PSI ? The check engine light is now permanently off as well so all seems good in scoobieville again .

Shit yeah 7k is heaps, you should be able to turn it up to around 14psi no worries, just watch out for detonation,

hi .

did a run out to pokeno today adjusted the boost to 10.8 she seems pretty happy with it .

another question ... i have a suspicion she might be running rich as there is a very strong petrol smell even so much that the wife mentioned it . also looks like she might be a bit heavy on fuel usage . Would this be worthwhile to take to a dyno shop to check ? If so can anybody recommend a dyno shop ? I am on the northshore so pretty much anywhere in Auckland would be good .

thanks for any/all help .

torque performance in avondale, speed source in walkworth, GCP in pukekohe.

Went and was kent at source speed a week or so ago and got my 7 tuned. runs so much better now. 212kw atw

could be running rich as its running low boost a standard wrx should be running 1bar or 14.7psi i personally run 16psi but i've got a vf22 on my wrx you could also invest in a fuel pressure regulator and adjust it after or during the dyno runs.

also do you still have your charcoal filter hooked up in your bonnet as when i removed that i got the strong smell of gas after my cars been sitting in the sun or garage over night after a long drive the day before.

[Guest]

awesome thanks for that playerB and QRAF . i will contact speed source and/or torque performance .

Yeah i know i need to get the boost up to standard but having a hard time with the gizzmo

i think best will be to get it professionally sorted .

also playerB how much did your dyno run cost ?

thanks again for the advice
