182 turbo failed mot on emissions.....

[LegoHead]

make friends with a tester, fixed!!!

I have a good mate who does mots.....but he would never let me get away with it.


I also noticed a t---- appear on fault codes. Injector fault? Might have been when i disconnected ignition leads?

 

[Dan@SJM]

Possibly.

I personally suggest getting your mate just to stick it on the emmissions test after a good hard thrash to see if it'll pass when its very hot.

IMO its miles out, getting it hot isnt going to bring it down that much! you need to get the lambda right for the co to follow, or thats usually the case! no leaks in the exhaust anywhere? however minor?

No leaks that I know of. I told the garage to sort the blowing exhaust out first so it should be fine.

Mine failed and had to get the ECU reset by Renault.

It cost £50 to put on the machine but they did give a print out of the emmisions after.

that may be an option...but will need a good remap afterwards, or will have to keep the boost real low.

 

[stan*]

who mapped it in the first place?

bbpt, I am waiting for a response....they dont do phonecalls anymore...

who built yours up bb or k-tec?

 

[stan*]

they dont much anymore at all...

seriously, drop the fuel pressure.

seriously, drop the fuel pressure.

I could try throttling the fuel line i suppose or where would the pressure regulator be?

I cannot see one on the fuel rail as in ktecs conversion, so guess it must be in the tank with the pump?

bb

 

[stan*]

fit an adjustable one.....

can i just give it to you to sort out.lol. It's giving me a headache.

they do!
when listning on the options go to accounts then a lady answers ask for andy!he is allways happy to talk

yes mate its a webber fuel regulator in the pump!which is in the tank!

 

[stevo172-RWD]

mine passed mot first time!
bbpt turbo same as yours but with k-tec sports cat in custom race alloy system.takes long time to idle properley though

I tried that way round, but they said email them.lol.

Is the regulator on the pump adjustable? I'll have a look tonight i think.

I guess my cat is the same as yours too, a janspeed one same as ktec?

 

[LegoHead]

It's going into the garage tomorrow and not coming out untill its fixed...

Might be a good time to try the omex? Can get it fully setup on rolling road for under 1500.

 

[RSTuning]

Why go the omex route for 1500 when you can pay for a map (dyno map live or not) on your current ecu and save a grand for beer

Well if you can get 300bhp out of this engine I'll be there! I just got paid so could come up one of the weekends if you are still free.

I'm trying to source some smaller injectors to get me through the mot....hope it works.

 

[stan*]

I give up....

 

[Dan@SJM]

Why not just fit a adjustable fpr like stan said? they're only like £50. and piss easy to fit.

 

[LegoHead]

Thanks for all the useful advice. But I am leaving it in the hands of a local tuners to take on the work. They have advised me to fit standard injectors, get it through the mot, then go and see pmurray or go for standalone or piggy back.

They dont think dropping the fuel pressure will help anything.

The cars misfires on cold starts and struggles to idle for a few minutes so dont think dropping the fuel pressure will help.

 

[RSTuning]

That might work but it depends on how the ecu was calibrated for the bigger injectors. It might result in a very very lean mixture and cause detonation.

We'll have the dyno into our new place in the next week ish so we can map your car then no probs

Cheers

Glad to hear that, hope you have some forgiving neighbours this time round.

I was thinking about the previous comments about mapping for a good cold start and idle, would it be worthwhile me travelling up on a friday night, dropping car off at yours and start mapping from cold on the saturday morning?

 

[Fred@BTM]

could you not cheat on the mot?

ie std ecu, std injectors and acidently disconnect the boost pipe going into the tb?

or am i talking crap? LOL

I think the ecu has resorted back to standard, as it has only started messing up and drinking petrol in last few weeks. So plan is standard injectors so far.

Then nice gentle drive to pmurray, put boost upto 1 bar and have 300 horsies!

 

[lucky]

Hmm, surely you can find a 'friendly' MOT operator if all else fails??

 

[stan*]

dropping the fuel pressure will cause it to lean of slightly, and so drop the emmisions...if they are telling you otherwise I really would question their abilities.
You wont get any problems with detonation as you wont be under any high load.

 

[LegoHead]

Well I have lost faith in the tuning know how of my local garage.

I was told rather angrily that dropping pressure in the fuel will do nothing to the amount of fuel going through the injector. f**king numpty....he said its like a tap, you cant get more through a tap by increasing the pressure.:S

Smaller injectors just made the car run very lean and fail to idle, so its definitely a map issue....

 

[Dan@SJM]

lol...

 

[Peperami]

he said its like a tap, you cant get more through a tap by increasing the pressure.:S

Erm, surely you can?

 

[stan*]

PMSL!

Well ive only been saying it for 5 pages!

Ditch that garage, they will f**k it up.

 

[McBunny]

he said its like a tap, you cant get more through a tap by increasing the pressure.:S

Erm, surely you can?

technically no you cant
the opening is the same size but you will get more throughput at higher pressure

 

[Josh@Renparts]

well technically yes you can then.... more pressure = more fuel through same size hole as it were..

lol. they have fixed my blowing exhaust though and good for storing the car safely!
