dont wanna go with anything aftermarket as the engine will only be in the car for a short while before the 408 goes in...
that doesnt make any sense... you can use the same aftermarket system on the big motor
that was my exact thought when i read that. if you plan to go bigger with the motor later on, aftermarket is the best choice you have
as long as its not a PMS

hey now, thats below the belt

A9L manual only, mass air
A9P manual or automatic, mass air

both work good. if they were the same price in a stick car i would buy the a9l.

there about a hundred bucks exchanged from a parts store. $75 or so from a junkyard.

A9P and A9L can be directly interchanged.


I agree that PMS kinda crappy. If you are going to get into tuning, then do it right.... Don't use a 'signal modifier' (yes you can get decent results with the pms, but it isn't ideal).

The stock ecu's will do quite well with larger motors. Camshaft design will have a bigger impact than CID will.
I ran my 408w quite well on the factory X3Z, and a cal'd MAF for several months while I was shopping for a tuner.

I have a link at home for a list of MANY 5.0 MAF ecu's. However, due to my recent bannola under my original screen name, I can't log in here from home.
Go to my site, contact me that way. Be sure to send meyour email, and I will send youa link to the site...


Good luck guys,
jason

SFI-SD3

That is an SD ecu isn't it?

There should be a large 3-4 digit code in the upper right hand portion of the sticker you pulled those numbers from...

Well done!

That's the link I couldn't find at work...

In reality, the differences between the A9L and A9P are so minimal, that the 2 ecu's can be directly interchanged.
