hi, ive got a 2001 bugeye wrx. and between 3500-4000 then 4500-5000 rpm it hesatates a bit (flatspots)...
i have tried looking this up already and come accross a couple of things
1. change the boost pipe connector... done that.
2. reset ecu... did that aswell.
still no joy. ive had it 2 weeks ish and run it on shell v power, could it be the fuel... i cant see why!
going to do plugs and filter this week...
can anyone help me please???
also i have plugged into a diagnostics and no fault codes.
thanks in advance

 

Coil packs or plugs

 

would coilpacks show up on fault scanner???

 

I don't think so but I'm not 100% sure?

 

No a specific coilpack fault wont show up, although you might get a Missfire Code.

I have a tactrix cable and OpenSource software, so could check it out for you, if you are local to me?

 

where are you? i am in tameside manchester...
i have had it plugged into a handheld thing and no codes came up? cheers

 

any more ideas??? please... lol

 

i live in heywood mine hesitates a bit when cold i drive the same as you it depends what you describe in a 1 to 10 ratio if you want come down to mine and we will compare the difference if any between the two cars aswell as havin a look at it pm me if your interested to do this

 

i am going to drop it to a friend (mechanic) 2nite. hopefully he has the know how...

 

mate do you have an aftere market dv ? if so put the standard re circ back on i had this problem and it was the dv infact 2 different ones which both gave my car a flat spot

 

it came with a bailey on it... no standard one. surely most have dv?
what make were yours? cheers

 

yeh,i agree.standard dump valve are well made and more than capable if a bit bland

 

If the lambda sensor is dying the ecu will pull timing, do you get full boost ?

If it is dying get a mapper to "de-select" the error code and it will never show up again, and you can ignore the £300 bill for a new sensor, as it's only there to protect the "cat".

HTH

i had a bailey dv and a turbosmart vee port and both gave my car a flat spot so i bought a standard re circ dv and the flat spot went get rid of the baileys

AFAIK all OEM TD05 16g's were "side entry" so will need converting to front entry to fit your Bugeye WRX. Then you will need the supporting mods and re-map..........I did this to my MY02 bug and ran a nice 320 odd BHP

320? Id be well chuffed with that. I already have a fully decatted turbo back system and a k and n 57i. I also have the td05 16g and a decat 3inch uppipe to fit. The lad i bought the turbo off said it would fit but i have to 'reroute my induction pipe'. I now relise that i need to change the housing. Any ideas were i can buy it from? Cheers

 

You can't buy the housing as it was never meant to fit the bugeye........it needs "Converting". Try AndyF, although he may only wish to take yours in PX.

Shaun

 

Or Mark @ Lateral Performance.

 

does any1 have either of there phone numbers? Ive already tried pm'ing andy.f but im yet to recieve a reply. Cheers

 

Try EMAILING Andy F. But you may have to wait about 3 days for a reply as he's out mapping most of his time.

As for the contact info, google "lateral performance" and "andy forrest subaru"...

 

Ive emailed them both. cheers guys
