Fox T-Bird/Cougar Forums  

You're exactly right Chrome.  It's safe  to say that Tom has impressed himself.

So be it as it may i always tune for  93. But not always.

No problem i am moving on. Sorry you dont understand what i was saying.
 
 
 Have a good DAY Y'all

The Rolls Royce (Packard) Merlin with the supercharger was faaaar superior to the Alison V16 it replaced in the P-51A.

Once again, only hearing the part of the response you want to.

I was not sure of the year of mustang, but I believe it was a 96-98 v-6. The engine blew and he found a loop hole. As long as they didn't get a failed code from the computer, it passed. Actually a problem with the way emissions laws were written in my state. They knew the car shouldn't pass, but passed all of the rules under the new obd2 laws.

First and foremost OBD2 Did not really come to play until 1996. But some Fords actually had a dummy plug that was not hooked to anything as far as i know. So a 1990 Mustang would not be OBD2 Compliant. If the inspector inspected that car as an OBD2 Vehicle the guy should be stacking shelves in wall mart.  Also it would be impossible to pass with a dummy computer any way. How would he set the monitors!!! I know it can be Dun but highly unlikely.  Also a lot of foreign cars got exemptions like HONDA. Honda got a 1 year extension on OBD2 Compliance. And some other foreign cars also got wavers. Example Volvo  had an exemption for obd 2 because their ECM did not retain monitor memory hold over. So they had to get wavered.  Now on the brake line. First i showed clearly the pass paper work my machine printed out. Remember the engine is under vacuum and actually sucks the exhaust in to the intake. If you dont believe me open an egr valve while a car is idling and see what happens to an idling engine. It stalls out. But i used a 1/4 inch pipe and the engine did not stall or fail an ASM 25-25. Reason being the test starts at 25 and not idle. Now an idle 15/25 is very bad because you need to be lean and clean at idle. That is where most engines fail. Now i dont know the numbers in your state for a pass fail by year of manufacturing parameters but the state sets the limits to a degree. Now i dont know why your vehicle failed and had higher numbers with a cat or EGR. What were the numbers and what were the previous numbers. I have to see what it was. Just saying it failed means  nothing. Now as for an OBD 2 car to fail an asm or dyno test would be basically very hard to do. Reason being when an obd2 is working properly it is 1.5% cleaner than fed specks. Thank you

NOTE the EGR valve on most newer cars of non obd2 design will not allow the EGR to operate unless the car is in gear and up to a pre determined speed. So they dont test for it. Plain and simple. Now what do they test?? It depends on the state. But most states that do pre OBD2 Normally do a dyne asm test. But normally up to and including cars that are under 25 years old only older vehicles are exempt in most states. Now some states like NY only do OBD2 compliant cars. Hope this helps

Not that I claim to have much knowledge in regards to them, aircraft engines always impressed and intrigued me one way or another. One that stands out in mind is the Pratt & Whitney R-4360 Wasp Major.

'94 and up T-birds and Cougars are in fact OBD-2, no dummy plugs.

Quite obviously this is what most of his posts are ever about. Loves to hear himself go on.



:hick:



 

No you won't.


Tom Renzo, possibly the MOST narcissistic, arrogant, self riotous and obnoxious post w to date.




Seems to me Tom, any quality info you bring to the site is muddied of not nullified for the above reasons. Keep it up though, it's entertaining. So what's the name of this amazing shop you run?

No problem i am moving on. Sorry you dont understand what i was saying. Octane is determined by many things built in to a particular combination . Example Axle ratio transmission Altitude induction system with or without EGR injector size. Thermostat so on and so forth. Anyone that does not know their exact timing and claims to set it without a light or whatever is beyond my even commenting. You should know exactly where your timing parameters are. Either way i messed with the regulars and got hammered because of the click. Well thanks i will remember all the knowledge i learned by this post. I am going to throw my SNAP ON timing light away tomorrow when i open my business. After all it is not needed right Chrome. The silliest thing i have ever heard in my life.

I do understand what you are saying. It is not the purpose of this thread. He wanted to know what octane these fellas ran with similar setups. Not identical setups, not what octane is needed. He was starting conversation. How come so many threads you post in results in fighting? How come you have posted the high dollar builds in three posts that I know of in order to prove experiance? WE GET THE POINT TOM! As for the timing.... I knew you would be appalled by that. Timing by ear is not for the squeemish. As long as it runs fine, sounds fine, and plugs look fine, there is no problem. A dyno would show it is in much better shape now, and although the timing would not show perfect, it would be close. That is all one can ask for without a dyno.....timing light or not.

On 1996 and later vehicles, you can tell which protocol is used by examining the OBD II connector:

'94 and up T-birds and Cougars are in fact OBD-2, no dummy plugs.

Just for the record as posted 1990 was not obd 2 nor would it be tested as so. That is without a doubt of being incorrect.

The 3.8 was OBD I till '96 when it went OBD II. I know because I use to own a 95 T-bird and it ran EEC-IV and was OBD I.
