A9L EEC ?

[yogibear357]

I am thinking of putting a 9AL ECM in my 5.0. Does it really make that much differents? Need input

[INCINR8]

Its just a stock mustang computer/ECM for a 5.0, 5 speed. Whats your setup now???

[yogibear357]

I have a stock ECM with SCT Chip some body told me 9AL is better I was just wondering what was better about it

[INCINR8]

What ECM do you have now? What year is the car?what type of motor ,trans did your car come with?

[vristang]

There are a lot of people who don't fully understand the differences between ecu's, but are more than willing to say that the A9L is the only one that should ever be used.

Was the SCT chip created for your current combo?
What ecu are you currently using?

What are the future goals, and what is your current setup?

There are some minor timing differences between the A9L and A9P, as well as fuel differences.

None of the differences, that I have found, will provide a performance advantage in either computer.

I have my chip out at the moment It's SCT 4 band I have to look to see what the number of my ECU . RPM dyno tune my last motor told me he was putting in 9AL but It is not and he does not have my old ECU my set now

347 dart block, 185 AFR, comp 282xe, holley intake, 70 mm throttle body,80mm pro-m, Hi crane 6, stock ecu

Can you please type in complete sentences?
Not trying to be rude, but I am having a hard time keeping up.

As far as I know, there is no such thing as 9AL, so an A9L is most likely being discussed.

So your old setup had a dyno tune.
Now, the combo you have listed is in the car running on the factory ecu?
But you aren't sure what ECU that is, yet?

Either an A9L or A9P will work just fine in your application.
But there are other ecu's that will work just as well.

Yes I am running on factory ecu for now. I need to put more miles on my new motor before I have it tune again. I was told that A9L is a better ECU. I still have to check which ECU I have now. Sorry about my retardness writing wasn't my best subjects.

[vristang]

No problem.

Unless someone stuck a 'batch fire' ecu in your car, you won't realize any performance gains by swapping out your ecu.

Most of the MAF / 5.0 ecu's are very similar in calibration.

Jason My Ecm numbers are E9AF14A624AA GTE

What is a batch fire

[vristang]

That was an attempt at being funny, but nerds are seldom funny...
Batch fire was used mostly in trucks. All 4 injectors on a bank were fired at the same time. Or maybe it wasn't split by bank? Regardless, the injectors were fired in groups instead of when each intake valve opened.


The only thing I can get out of the number you posted is the year of the part
E9 = 1989
Google may be able to help you match that number to a 'Catch Code'...

The catch code should be on the Ford sticker though...

these are the only numbers on it 680ECM
ISO-9001:2000
9001 1001

[yogibear357]

IF anyone can give a little more info would be appreciated I did a search, went to a Ford dealer no luck there either. If not thanks for the help so far

what year/model vehicle are you talking about? are you using the original computer?

[yogibear357]

1988 mustang 5speed LX 5.0. with Mass air
This guy that dyno tune my car said he put in a A9L it's not. Here is what I come up with for numbers on my new computer

680 ECM
ISO-9001:2000
9001 1001
E9AF 14A624 AA
GTE

I found out what computor I have. It is a 1990 F-350 Ford dump 5spd 460 eng EFI one ton.
