4agze EPA :( mechanics ?

[dex13b]

Hey guys, i have recently been EPA'd in my AE82, the car has a AE101 4AGZE conversion and is running a saard adjustable fuel pressure reg and a bigger fuel pump. The mechanic said that if i changed the fuel pressure reg back to non-adjustable and if i passed emissions then he would not mind about the other modifications. But i am concerned that the car won't pass as it does in fact run a larger fuel system.. The computer is from the ae101 and might be re-mapped too ? Can anyone suggest a good cheap mechanic that knows his stuff about 4A's ? and corolla's ? etc I live in Sydney - Wahroonga, so anywhere in sydney is good i guess.

Can anyone help with my situation? anything will be appreciated.

Cheers,
Alex

check what fuel pressure it is running, and then get non-adjustable to suit.
larger fuel pump will make no difference

different injecotors? different ECU? remapped stock ECU (is that possible?)

didn't the car have to pass emissions for the engineers certificate?

Im running over 400hp on a standard 4age FPR (blacktop). My old 4agze wagon was running big fuel pump etc too and i just used the standard FPR.

Remapping stock ECUs isnt something that comes up often. People normally use piggybacks as the standard ecus dont get remapped etc

Mate, EPA's hey - im lucky i didnt get EPA'd in the old supercharged AE82.

Take the car to a performance workshop, they should be able to sort it out.
Give Chris a call, he is in Cromer, he tuned my AE82 when i got it on the dyno.
He knows his forced induction (SR20's mainly) but he does all types of performance work.

if the SARD FPR is set to the same static pressure as the factory (35-28psi, engine off, pump on) then it will keep rail pressure to the same as the factory FPR - and if using the factory ECU, will produce factory AFRs - i'd say your engineer is 'mod--averse' and any visual change is going to upset him/her.

Pump will flow as much as the FPR allows - and if you are running a factor ECU then the flow capabilities of the system are moot.

Ditch the engineer and find someone competent.

fwiw: i recently got defected in Qld (for other issues) and the transport cop was not vaguely concerned about a sard FPR mounted on the strut brace.

yeah the car was engineered with a standard '93 corolla fuel system ? but clearly that isn't whats on the car.. ok so basically if i find a standard FPR then i should have no problems with excess fuel?
I have heard of standard computers that are able to be remapped slightly, but clearly not to the capacity of an aftermarket computer. I have no evidence that it is, just what i have heard from the previous owner.
It does let out alot of exhaust carbon, this could be caused by a highflow cat or something ? it looks standard but who knows if its been punched out or not. It's not the engineer i am trying to impress, it's the RTA in NSW that deal with emissions controls. They need to know that the car is not putting out worse emissions from standard, and evemn though i already have an engineering certificate, they believe that some of the equipment on the car is being used without having it cleared and verified to comply with their standards.
thanks for the interest guys ? are there anymore workshops i could potentially take this to and get a good idea on what i actually have to change ?
or anyone that might sell me a standard FPR ?
thankyou

correct, and if you set the SARD FPR to the same pressure, then also correct

open up the ECU case and look for mods or a sticker on the ROM that looks out of place

boosted toyota engines tend to run rich - mostly to protect the (probably poorly maintained) engine from running lean under boost and rapidly destroying pistons and heads.

If you think the CAT is just a shell, shove a stick up the zorst.

if it's running the factory ECU, factory fuel pressure, factory injectors and has a CAT then it should produce the factory spec emissions and thus pass a gas test.

and shouldn't be spitting out carbon, not with a cat..

which is probably why the EPA pulled youup if you have soot stains on your bumper....

This is not likelyfor your car unless there is a big sticker with 'Mines', ' Sard', 'Tom's', etc, etc on the ECU. The Toyota ECU's are encrypted and locked down HARD, so it's no easy feat to 'chip' them as it requites a new ROM, CPU and associated daughter board to run. Definitely not a weekend job like a Hondata... Anyone who tells you otherwise is lying.

The more likely scenario is a piggyback ECU, but you will be able to find that pretty easy by looking under the dash.



I also was defected in QLD the other week, and the cop overlooked my Sard FPR hanging off the strut brace, the HID's, HKS cam gears under a clear cover and the Apex'i pod filter in it's little box.

Sorry If I missed it, were you at the mechanics to get a green/blue slip or was it for something else? If it's a slip your after I can help you out there.

[fixeruperer]

i dont know the laws there, but are you trying to get it passed as a standard car, or are you getting it engineered as it is now ?.

if its as a stock car, youll pretty much have to do as they say. If its getting engineered, you should be able to do what you want ? just get it signed off.

sorry ill clear this up, i got a letter in the mail from the government basically saying that i have had noise complaints and that i must go and have the car inspected for a noise test, while they did this they also check all emissions equipment is working the same as standard. The car has an engineering certificate from when the motor was first put in but i think a few things have changed since. i think it's more than likely that the cat is poked out. i can't fit a stick or anything down that way as i have a silly shaped exhaust which bends to clear parts of the suspension. perhaps something plasic might work...
So TERRA, i have not noticed a piggyback computer, under the dash (sort of behind the head unit and pocket) i can see what seems to be the puter, nothing special about it, just loooks like a plain boring steel thing... do you think i will get away with changing the pressure reg and a new cat perhaps ?

...i got a letter in the mail from the government...

You didn't get a letter, it was lost in the mail, delivered somewhere else.
Any more, 'Return to sender, addressee unknown/moved'.

^^^ This.

Just make it look as stock as possible and make sure there's a cat.

hahaha, yeah except they cancel your rego if you don't do it, ok thanks for your help guys ! and i'll keep you posted
