How can I tell what type of LM I actually have. Here is a close up of the sticker on mine:

What I'm wondering is: Is this a T1 Daytona Shelby Z (Auto) or a true T2 Daytona Shelby Z. Is there a web site to look up the sticker info?

Thanks,
Paul

Im thinking a 366 is a 87 T1 Auto.

What do you want to do with it?

Well, it's for sale but I was under the impression it was a T2 LM. Is there any difference between the T1 "auto" and a T2, besides the obvious. I mean, the fuel curves, spark, timing, boost rating.

Thanks,

Everything in the cal is different. The T1 auto in 87 was actually a log style intake, so no provision in the code (slight possibility) for the 4 wire AIS.

The computer, however, can be made into a T2 computer, with just a cal change.

As my Google skills have appeared to help, Yes, this is an auto LM. I did a search fro it and found a RockAuto listing for a Shadow:

Shadow Part Number for LM at Rock Auto (http://www.rockauto.com/catalog/catalog.php?carcode=1097737&parttype=2896)

So, in a T2 conversio, what exactly would this mean? If I were to be doing the T2 and wanted to use this, would it need to be modified any?

The PN is 5233366 which according to:

http://www.moparmagic.net/fwd_mods.html

is for a 87 TI auto

Are there any 'major' differences between a T1 auto and a T2 manual LM? I know the T2 one is sought after for the T2 conversion.

No major differences, but if your switching to a true T2 style, the programming for the 4 wire IAC will not be in the LM. Plus the TI will probably be limited to less boost.

It is useless for TII convertion.

That's what it boils down to then.

Thanks Harry. <--That's a genuine Thank You, not sarcastic :)

It is not useless for a T2 conversion.

If you want to use that computer for your conversion, it is perfect. Just needs to have the proper code put into it, which requires the chip to be de-soldered and a socket to put in. Painless, and can be done in ten minutes.
The you can put whatever code you want in, T1, T2, 3 bar, etc.

Hey guys, just to double check, the 5233366 LM is 87 electronics (ie Non-L-body), correct?

I did a search for that PN today on a LM I have, and one result said it was for an 87 shelby charger (here: http://www.ecudirect.com/finditfast/searchdesc.asp?rbutton=673)

Just need to be sure before I unsolder the chip.

thanks,

comes up as 87 t1 auto on the otehr site. as long as it has an external map its good to use on other external map cars from my understanding

well, no external map, which is what I want for my 87 electronics conversion on my GLHT. BUT, changing a case could produce the same result for the wrong LM. I just dont want to go to the work or socketing a LM only to find out I did the wrong one! :)

clayThat number does check out to be 87 Turbo 1 A/T on our listing in the Knowledge Center at

http://www.turbo-mopar.com/forums/knowledge.php?page=section6#6.1.5

Being an A/T cal it would not have been used in the Shelby Chargers which were M/T. The SC number is 5227337 per the KC listing.

If you are going to socket the board and change the cal it doesn't matter whether it was originally for auto or manual though.

darn it! I forgot all about the KC! well, thanks Barry! both for the answer and the reminder! ;)

if you are going to an engine wiring harness with the MAP under the hood, you need a LM that is setup that way, and just changing the calibration cannot change that casue the wiring is different. or at least that is the way I understand it

yup, when doing the 87 electronics conversion you have to swap in an external MAP and the associated wiring, which isnt much. 5V from the LM, signal to the LM, and a ground wire close to the MAP sensor is all.
