im sure the sensor at the top is the lambda, as ive changed it to sort my fueling out but it aint done anything.
whats the sensor on the bottom of the downpipe? will it affect my fueling?
rev 3 turbo with decat by the way

ive got an mr2 rev 3, and ive recently replaced the lambda sensor for 1 from rogue. ive no doubt they are fine, but my fueling and emmisions are mental, so im gonna try another one. there are a lot on ebay for toyotas, and they look the same as the standard one i had on before. as long as they are 4...

failed the mot today on co emissions lambda reading and all the others were fine, but it failed on co which would not come below 0.7 ive got no cat, and all the usual mods, but it does smell really rich and goes through a lot of petrol so ive changed the lambda sensor, but still no good. 02 sensor? ...

this plug for the vsv.... where abouts under the inlet manifold is it as there are 3, and 1 i pulled out made the idle go higher, so not that 1!

any help plus a pic would be great

cheers rob, imoc forum is without a doubt the best advice forum i have been to.

ive had fluctuating readings since having my blizt dsbc fitted, so i decided to turn it to off mode, thinking ill go easy and see whet happens. it wouldnt boost past 0.7 bar, which i think is standard, but i will go up to 1.2 when boost controller is on, albeit spiking and jumping, so im assuming so...

could i not just use the sensor i have and use the readings from the hand commander?

yea, its a power fc with hand commander. im thinking about not using the hand commander and selling it. ive got a boost controller and boost guage already and turbo timer, and my cockpit looks like blackpool iluminations. whats a wideband lambda? is it something i need to get before i go to get the ...

can you point me in the direction of the seals?
pics would be very good
cheers

ive recently replaced the lambda sensor, which i think is what you are refering to as the o2 sensor.
got it from rogue, but it didnt seem to make a difference

wheres the o2 sensor? is that the one on the downpipe?

im pretty sure its from the exhaust, you can smell strong fumes smell rather than petrol.
i use shell optimax, which hums a little more, but i think its overfuelling a lot

ive got a few mods on my rev 3 turbo. induction(blitz sus), intercooler, downpipe, hks ssqv, blitz dsbc, plugs and leads etc and ive recently put a new lambda sensor from rogue on. im sure its overfueling as it cost a fortune in petrol, and when i pull up anywhere people comment on how strong the fu...

ive seen a few members on here with the stainless hot pipes that have the hks flange welded on, and no bolt attachments, like the pheonix power ones. where can i get one? also ive seen a pipe that replaces the rubber intake pipe to the turbo and is about 9 inches long, so basically you just attach i...

try nipping the bolts on the cam cover up 1st, they vibrate loose sometimes, and should only be nipped anyway.

anybody?

could uou give me a bit more ibfo on where this plug is plz?

how would it restrict the wastgate from opening?
i was thinking of getting a berk downpipe, they any good?

im assuming the vsv has been disconnected, in fact im pretty sure it has, as the chap who does it knows his stuff(xo motorsport) the downpipe, im not sure of the make, it seems ok, although when putting a new lamda sensor on, the plate it sits on cracked a little. would this make a difference? also,...

ive had a down pipe, ic, hks ssqv, blitz dsbc spec r boost controller and the usual plugs, leads, disi cap etc. ive had a good play with the gain and ratio settings, but im still getting spikes in lower gears. ive tried gain from 15 to 50, whist setting the ratio from anything from 30 to 45. no joy!...
