What To Do Next

because you are messing around with the standard factory settings in other words as soon as you plug a computer in to the ecu and start messing around with things ie more power pops and bangs. apexi power fc is not a road legal ecu its a pure racing ecu.

i might also add nobody is gonna tell you this because then there would be no need for tuners

as long as the car is insured and has a valid MOT you can do anything you want to your car whether its remapping the ECU or not

...and for the record pre 93 scoobies can run full decat and sale through mot emmissions

How many pre 93 Scoobs are they about now?

Without trying to upset anyone here -

I'm with JW on this one. I know alot of you guys are into big power and fair play to you, but IMO I would rather run around in a 300 BHP PPP STI which is legal than worry about getting pulled or searching for 'friendly' MOT testers. Now just for talking sake, if someone with a full decat post 93 car crashes into another vehicle and both cars are written off and the police/insurers find that the car was not legal because of the exhaust what happens then? Are you then classed as not road worthy so therefore you are not insured? Just curious.

As for pops and bangs, they sound good but if its used every day it could become a chore.

Only my opinions.

With regards to the panel filter needed for the map...if my car has PPP on it, would the filter have been changed

at that point or will I just have the standard one?

My one is green and I think I remember Andyjdmsti looking at it when he was going to sell me one, but he said

it was ok???

Newage PPP use the standard paper filters as Prodrive found no significant gains using others.

in all fairness there are not many pre 93 scoobs left on the road but there are some and my mate is rebuilding one just now, and if 2 post 93 cars crashed and it was found out one never had cat on it then is it not road legal so the driver would prob get done for not having insurance. just my thoughts on wot would happen. but your mot is fine if your car was tested with cat on it and then you remove it to put decat back on you are still mot'd

OK so if you had a full decat, then on say thursday you put a cat on it for a MOT and it passed, then on friday you took the cat back off and saturday you crashed then surely a lot of questions are going to be asked of you and your 'friendly' MOT tester.

Remapping is not illegal, neither is a lot of mods. Some are sold as track only for liability reasons of the manufacturer. What is illegal is when the car isn't road worthy through a combination of some of these mods. If you're running apexi and a cat and you pass emissions then you're fine.

Obviously if your car is modified then you must declare that to insurance to make you driving it legal too. KM know all about my mods.

Jw gotta ask you this but why are you preaching about the legallities on things when you are the guy that runs around with illegal number plates??? and for the record pre 93 scoobies can run full decat and sale through mot emmissions, and i know of a 95 classic that sailed mot running a full decat. and just so you know that anybody that has a car mapped is illegal!! and all the mods you have done to your car with out telling insurance is illegal, need i go on. so even if you change your plates your car is still illegal.

JW not aiming dig just at you but seems like you wanna keep saying it illegal!!!!! and i see you learned a new word! ILLEGAL!!!

thank you and good nite!!!!!!

Well now, let's have a response imbued with the usual erudition. Here goes: One: I DID not preach about cars being illegal, I made a statement of fact and then merely stated that for me, it was not the right choice, there was no preaching involved. Granted, the plate is illegal, but the penalty for such a misdemeanor is negligible whereas the penalty for decatted exhausts systems on Newage cars is not. I am well aware that the old Subarus don't need cats and at no point did I imply that such vehicles are illegal. The car in question is an MY07 STi - which would therefore make the car illegal with a non-cat configuration. Do please read the post's contents in their contexts. I'm well-aware that modding a car without the insurance company's knowledge is illegal, hence the reason why ever last one of my modifications are declared - one must endeavor to get one's facts straight before making such rash assumptions. In fact, (and I may be wrong about this) failing to declare mods may not be illegal,as to my knowledge, the penalty for such a misdemeanor is not a legal matter, it is simply that the insurance company doesn't pay out on claims.

So to the contrary: thank YOU and GOODNIGHT!

Just something from my side....

I have a 3" turbo back system i.e not a cat in sight. Car is a MY04 sti with a 20G,70mm CAIK, Walbro, AVCR etc etc and my car goes through an MOT without failing on emissions . No cloak and dagger MOT stations, i have been to various. Car was mapped by the man AF.

Some modern cars will go through MOT after mapping without a cat as they are usually leaned out. I know they are running closed loop when on low load but my car goes through without issue. My AFR's are fine although leaner in places than before my first mapping.

Also anyone with a WRX (JW i believe ,although looks like a nice sti dude) may most likely find, providing you still have your Tumbler valves in and operational, that your emissions may well be within the legal tolerance even with a de cat and map. This is due to the efficient running of the engine and the complete mixing of the fuel in the inlet manifold due to the turbulent flow that the TGV (tumblers) develop.

What exactly is the punishment for excessive NOx and CO emissions??.....AFAIK its usually a 21 day horty to produce your docs and get a MOT station to sign a chitty proving that your car now passes the test.....not sure on this one but please correct me if im wrong.

As to the original post about mapping in "pops and bangs"... in order to do this your fuelling will be increased higher up in the rev range, thereby when you lift off the throttle the excessive unburnt fuel will then go into your exhaust and explode. While this may be entertaining it is counter productive with regards to power as you are losing power by running to rich, all be it hardly noticable, due to area of increased fuelling. But you are also causing your turbo to do things its not supposed to . I.e uneven pressure in exh system i.e changes in back pressure, sudden changes in exhaust system temp, pressure pulses causing extreme changes in turbine velocity, excessive carbon build up on turbine blades- reducing effiecieny and creating possible im-balance

Your turbo will take this, but it is not ideal conditions for it to operate in and would most likely causes failure before one that was operating in more normal condtions. Oh... cats tend not to like explosions happening in them so id not waste my money on a sports cat to see it get blown to bits.

Just my 0.000002p worth

Cheers

Very interesting reading re. the emmissions of a decat. If that was a guaruntee, I'd go down that route. And lastly, dude, how do you know all this stuff!?

[RS Grant]

Pretty sure that Andy said the 'pops and bangs' were a result of opening up the ecu so that it doesnt go into closed loop on the over-run between a set area... and its not higher up the revs, only happens when the throttle has been completely lifted between 4500rpm and 2500rpm, I occasionally get a wee flame when changing gear at the top of the revs, but thats only when the car is out on a prelonged spirited run.

If you accelerate hard using 100% WOT into 'the zone' then it may/may not produce the effect depending on how quickly you snap the throttle closed, however, part throttle into 'the zone' and you'll get the desired effect. If I go up to over 4500rpm and let it drop through 'the zone' using engine braking, then it will also not produce the pops and bangs either, unless I touch the throttle myself to provoke it.

I would agree that this increases EGT's though, I dont have a gauge to monitor them, but for the reasons you've mentioned... I cant see how it wont raise them as a result. The power thing is a bit of a mystery though, mainly because other cars with pretty much identical spec & mods, that dont have the 'pops and bangs' make near on the same figures as my car did on Andys DeltaDash when I was having it mapped.

Cheers,

Grant

Have you considered

TAKING THE BATTERY OUT

TURNING IT OVER SLOWLY

THEN SMOKING YOUR OWN ROD

[emoe]

Personally speaking, i think you should mod your car however you want, there is so much antisocialistic Nazi laws in this country as it is, and the repressive regime that we live under just gets heightened every day, and when you arent 'allowed' to modify your car to your personal preference thats just communistic and repressive.

Added to the fact that we have to abide by laws and regulations that are made by those who dont get penalised by them in the first place, and those laws not only stop us form being individuals and might i add, what harm is it to be individual and modify your car, house, clothes, face or whatever if you dont cause injury harm or loss to others directly or indirectly, but those laws are also paid for by us in taxes, and then policed by people who on one end of the scale love the thought of being powerful enough to totally screw your day, and opress you, to those who work for the system and hate the regulations it imposes.

I say lets revolt!
