F**king Emissions,F**king Mot\'s

[Eddie]

I would love to get hold of ethanol as I mentioned in my post a few up, who sells the stuff ?.
Had a quick look last night but no joy.

I will keep looking.


But if anyone know then great

MOT GUY was a little more accomadating today, he let me try and alter settings whilst reading emmisions, then and I think this was the problem yesterday, his boss came over ranting like a C*** get that probe put of that you will F*** the machine up ( I thought it was designed to read exhaust emmisions:) well he did not like me saying that, the boss starts at his employee then telling him and hes got a MOT to do in a min. (well I tell you what I wont be taking it to that garage any more, had my money for mot then winges when I try and take it back to retest to get it past)

Only got my readings down to 5.00 co and 1288 ho, took it for a good blast as well before hand, but maybe not good enough.

Are well its in WGT Monday so see what he can do.

Maybe it\'ll pass when you get it mapped? Prob running rich or the lambda sensor is faulty

[Eddie]

Fingers crossed, get it mapped and take it back Tuesday for another try:)

Eddie you have a PM. Ring me.........:Santa

[TINT DESIGN]

anyone willing to travel to Uxbridge - we can help pm me and we\'ll see what we can do... our RX7 passed no trouble... straight thru with no cat on it and tiny little box at the back...

[probedb]

Mine went through ok (a little high really) yesterday on a standard PFC map (so rich) and no cat. Nice MOT tester I had...car gets mapped next month anyways

Ok, I have a question for you Bramble... (Sorry to resurrect this one)

It is abundantly clear the distinction between MOT testing a UK vehicle, and an imported (Japanese) vehicle.

Here is my question. I have a 94 Touring that just failed the emissions section of my MOT this morning. It is imported, however it is imported from America.

Do you know how that would classify as? Mine was tested in class "IV"

I have 3" downpipe, Hi-Flow cat and Apexi N1 Dual exhaust. I swapped out my stock ECU for the PFC some time ago...

Now, everything else on my car passed with flying colors, just CO and HC were DEFINITE no-go\'s (read about 5.70 and 1,558 the entire time). Course, my car had also been idling for about 15-20 min, though I\'m not sure if that would make much of a difference.

Thanks,

Levi

(Also, would you mind please giving a brief explaination of what the 3.5 mentioned is referring too?)

[rx7veilside]

the 3.5 is 3.5% co emmissions and yours is above this it needs to be 3.5 or below also the hydro carbons will drop as well

[Fendamonky]

Right, so basically fiddling with the settings on the PFC should be able to get me this?

I saw on the readout that supposidly I had an allowable CO emission of 0.20... perhaps I was just reading it wrong. The guy who did my test is really cool and was hoping to find a way to get me through on a loop hole but was unable to find one.

When did the 13th Ed. of the VOSA (manual?) come out? perhaps this station has not recieved it yet..

Thanks!

BTW~ I figure I will introduce myself (tried to in the Who\'s Who section, can\'t post there as a guest though).

My name is Levi, got my VR \'94 Touring about this time last year then moved to the U.K. in Feb with the U.S. Military. I am just now getting around to MOTing my car and all that fun stuff because it didn\'t arrive from shipping until AFTER I got deployed to Afghanistan. Just got back so just now doing it all ;-) I\'ve been on rx7club.com for a little over a year now, posted in here because I know the rest of the yanks won\'t have a friggin clue what I\'m talking about when I say MOT...

[rx7veilside]

you need someone to advise how to drop the pim voltage to get emmissions to 3.5co

[Bramble]

Right, so basically fiddling with the settings on the PFC should be able to get me this?

Exactly. I dont frequent this site often, but if you PM me on FDUK.org/forum I will chat with you about it.

Done, Thanks =)

Right, just posting this here as a source of info for other guys trying to pass their Emissions part of the MOT:

I passed mine this morning.

I have: 1994 US (Imported) FD with the following mods that would effect emissions. De-Cat Downpipe, Hi-Flow cat, Apexi N1 Dual Cat-back, and the Apexi PFC w/ Commander. Stock injectors (550/850) and stock fuel pump.

To make the car pass emissions (need 3.5 for CO% and 1200 HC since my car classes as a Japanese Import and it is pre \'95).

With the PFC (and similar set up) passing is no problem. When you are in the booth (before they hook up the sniffer) go back into the "Settings" menu, select PIM. Do not select any option but the one originally highlighted (this will flood you out and make your car stall), click next.



On the first screen (with RPM\'s on left) change values to:

1000rpm ---> 96.0
2000rpm ---> 96.0
3000rpm ---> 96.0
Leave all other RPM values alone.

Now hit next and change the value for the voltages to:

1.0v ---> 96.0
1.5v ---> 96.0
2.0v ---> 96.4
2.5v ---> 96.4
3.0v ---> 96.8
All volts about 3.0v are set to 96.8.

With this setup I dropped from 5.6% down to 3.3-3.4% without disrupting idle or smoking. Also, if doing this still doesn\'t get you below the limit, and your tester is cool see if he will let you rev it up a bit and pull the reading during the decel. I registered at 1.2% on the decel before I started fidgiting with the PFC.

As I believe was mentioned already.. make note of your current values before you change ANYTHING. Change your values back to the way they were after you finish the sniffer test so you dont screw up your engine while driving around afterwards.

Hope this helps some of you guys out!

for any one looking for ethanol.
its ethyl alcohol , the same as you get in your bottle of single malt scotch, or more importantly, the same as in your bottle of methylated spirits. (this is ethyl alcohol mixed with methyl alcohol a colourant and oil of wintergreen to make you puke.) You may be able to get isopropanol from an automotive paint supplier.

All volts about 3.0v are set to 96.8.

Doh! I meant "All volts above 3.0v are set to 96.8" damn typing without thinking...
