Hi all
I have noticed a whistling noise coming from the engine when i start the car and it idles can not hear it when driving Any ideas ????

The car is backfiring when i come of the throttle nearly all the time. Could this be the coil packs. Car drives fine and sounds great

1995 WRX, chip, 255 FP, Full decat, Green Panel filter

Thanks Neil

 

Mine pops and bangs regularly but not all/everytime, i also run the same mods, plus a VTA which causes a little bit of over fuel and aids the cause.

Has it only started this since you fitted your new ECU and chip??

 

Yes i fitted all the mods and chip at the same time. I have been reading on here and a lot say they loose power i dont think i do just pops sounds good lol

 

Yeah, will just be over fuel, not ideal and some will say causes 'bore-wash'. You thought of fitting an AFR gauge, just so you can see, i have one fitted.
Can't see you losing any power, some of the lads have the pops and bangs mapped in on a remap.

 

Yes fitted a cheap one and jumps all over the place but looking on here thats fine as long as its reading rich on full power. Why would it overfuel i still have the original DV
Thanks Neil

 

Good move and yes it sounds fine .

The fuelling is increased on the chips map to cope with the extra boost/power, better to run a 'little rich' (not too much) than a 'little lean' .

 

Just got my self 4 coil packs so will check them and replace if they looked naff
Thanks Neil

 

She will appreciate those, doesn't sound like you have any problems in that resect though. she would be failing under load if they where to fluffed.

 

Yes they are second hand but got them for a good price so even if only 2 are ok it will be fine, want to change the plugs so wanted parts to change if needed rather than taking the car apart again even if the girlfriend says i love it
Thanks Neil

 

Your girlfriend will be right (as per ). You've got to love it, otherwise you'd

 

Yes when i messed up my z4 soldering i nearly but worth it in the end

 

I know the feeling with that one, spent 2 hours with the iron and a magnifying glass doing mine, put the chip in and the bastrd socket fell out

 

Makes me glad i am not the only one all sorted now got a 7d with socket in from factory and bought another z4 incase that did not work (note to myself stop spending money)

Yeah thats the thing with these babies, your never the first and certainly will not be the last.

Note to you; You own a Scoob.
