Evenin all....

Just read a couple threads about engine lights coming on, aparently early newage's comon for it and light goes off after 5 engine starts... will try this tomorrow.

Thing is this evening, driving on a dual carrageway, at a steady 60mph, the light came on for no reason, engine note never changed, and car drives no different to normal,still boosts well etc just strange how it came on( first time its seen the snow lol) have turned car off twice since and still on, ( will try the 5 on off thing tomorrrow)

any ideas people? thought id check on here before get it plugged in

just been looking in my owners manual, and says if stays on its emission problem, only engine fault if flashes... needs to be turned off tho or fault memory read for piece of mind

any help apreciated, cheers

 

are you running a de cat down pipe?

 

Often a faulty Lambda or EGT sensor. Anywhere with diagnostic equipment will be able to confirm. Not too expensive but can be tricky to change as they are often seized into the exhaust and can be in quite inaccessible places.

 

Quite a few possibles - spark plugs (if modded), coilpack, neutral position switch, lambda, etc.


Best get it plugged in.

 

getting plugged in tomorrow...... yes ive got a decat downpipe( tho was told only up pipe replcement brings light on) also a walbro, hks filter and forge dv.

 

Hi James,
Under light load at a steady speed the lambda tries to run as clean as possible, the ecu reads an out of range value due to someone removing one of the cats.
I fitted a sports cat and was warned it would do this, so just ignored it !
(For two years !)
Had it checked once under warranty just to be sure, then it came back on again a short while later.
HTH

P.S. If you cane it everywhere it won't come on, sorry officer....

 

hi Dunx, LOL yes it was, driving at a steady 60mph for about ten mins then it came on...s till on today too lol. getting it plugged in on my mates lap top tomorrow so will see, what fault am i expecting for the decat being fitted? was warned might do this but only if removed up pipe, i would ignore it, its just so damn bright LOL

 

Sounds like 3040 or something fault code, which is the cat not working properly,

 

lol it wont if not there will check the codes later this evening

 

just had it plugged in lol. cat ,alfunction obviously if no got one lol

 

Genius !
Well spotted mate, I still worried even tho' I knew why it came on, AGAIN !
Just thrash it everywhere....

Sorry !

haha will do gettin mapped end month hopefully lamba prob 2 was readin lean all atime to lol thats worryin tho assume also somethin do with cat

 

You have some options to sort this code,
1, remap and the mapper can take it off (cel light)
2, manual cell fix fits into the rear sensor, the into the exhaust sorts out the light not coming on,
3, mechanical cel fix which is wires fitted to the rear sensor to eliminate the cel..

 

CEL for the decat is P0420

Mechanical CEL fixes not always 100%, I'd get it remapped and the mapper will permanently erase the CEL for you

Also will get a lot more from your TD04 than when it left the factory

yes end of this month hopefully @ mocom will have td05 fitted too so no need to worry bout td04 lol

 

James

I went from my TD04 to a front entry TD05

I must admit this was the best bugeye mod I ever did I could tool around doing whatever I wanted without fear of smashing anything expensive like the gearbox or clutch

Just note that the mapper actually de-tuned the car slightly to avoid disaster as the TD05 is a tough critter and in the end it shagged my clutch (instead of the gearbox) LOL

What other mods have you gone for....sti pink injectors, fuel pump etc ??

Cheers


Shaun

 

cool, cant wait

full s/s system on, decats, walbro, hks filter, td05 and remap will be the spec, been told to expect 300bhp and equal torque so thatll do me on std injectors too which is good, tho if want go over 320bhp then injectors need changing

 

Class

300 BHP on the cards then

I'd look out for a STi intercooler and a FPR to raise the pressure about half a bar and .........

Shaun

 

yes considered a fpr but been told not to bother lol, hmm considered front mount too but can go on adding stuff forever lol

 

Hi James £200 for a regulator will extend your injectors output enough to reach 320 BHP..... it's the route I'm taking on mine. For now ! LOL
