Smec I.d??

[WOP'R]

how could i tell what smec i have? reason why i ask was because i bought T2 smec to replace my T1 smec on my car. Turns out i already had a T2 SMEC?!?!?!? this car is an odd ball as turbovanman is witness to:nod:

anyways since then i went to the basement to find the T2 SMEC i bought a while back. So my question is, is there sapposed to be some kind of ID number on it somewhere cause i cant see anything?

[looneytuner]

there should be a peice of paper with numbers printed on it. Most are barely legible by now. If that is not there, ??? since the same computer could be programed for different engines.

[cordes]

if you have acess to a burner, you could read the chip and compare it to a stock cal with d-cal or chem.

[butchsuppe]

You should be able to ID you computer by P/N, the last 3 numbers of the P/N are on the eprom chip in the logic board. I got a service part T2 computer from a 89 Shelby daytona with a P/N P4532132 which didn,t match any numbers I found for a T2 cal. Posted a question about the P/N + was told it was a foctory service part replacement. My scanner did verify it was indeed a T2 cal.

no paper
dont have a "burner"
and what the heck is a P/N:confused::p

[cordes]

Part number.

Pop the computer apart. There is a silver sticker with 3 no#s on it on the lower left corner. This sticker is on the chip. Those numbers will be your answer when you tell us what they are.....

[WOP'R]

the three numbers on the silver sticker on the chip in the reson are...
069

Also on the inside of one of the plastic halfs has the following number stamped into it...
5227341
PP1

hope this helps

[butchsuppe]

069 is a 89 T2 G+H SMEC, found info on D-CAL, may be used on others as well.

89! anyone know if the 88 harness can plug into the computer? or are the plugs different?

btw thank you

If I am not mistaken they should both be SMEC, and it would most likly work if it is the same body style as was mentioned by Butch.

88 and 89 are 100% interchangeable. Just like 90 and 91..

[WOP'R]

thats what i thought:amen:

thanks all

[WOP'R]

ok, I took the computer, which I thought was a TII computer, out of my Daytona to get the number.

What I got is : 5233244

The "244" is from the silver sticker on the chip inside the computer.

Can any one identify this ?

88 Daytona T2 man trans

thank you butchsuppe. can ypu please tell me where you found this info? I asked the question over on turbododge.com and i have some ppl telling me its a T1 while others are saying its T2. Also some one has listed a SMEC with that part number as an 88 T1. Ive i got no clue whats going on!!!!


BTW are you butch from turbododge.com?

[turbovanman²]

Yea I,m on that furom too, lhttp://autos.groups.yahoo.com/group/D-Cal/files/ This site is D-Cal, you must register for it. look under data base for computer part numbers. Using a span-on scanner programed for a T2 on a T1 computer will give you a code for the ACT sensor, I,ve learned this from experiance. On the wiring harness pin location, the only differance between the T1 + T2 is the signal wire for the ACT which the T2 has and the T1 doesn,t. All that is nessesary to convert a T1 harrness to T2 is to run wires for the ACT signal + grd.

Or you can have the flag for the charge temp turned off. Then you won't get the check engine/power loss light anymore.

interesting, i had the plug for the atc sensor so i guess the harness is also form a T2

My 2 '89 Lebarons are 2.5 T-1 cars, and they have the Chg temp wiring from the factory. I also noticed this in the JY with many other cars in the '88 to '90 range of years. Seems like AA bodys, and P bodys didn't get it no matter what year unless it was a T-2 or VNT car.......

not to start a new tread i was given a 88 semc today the box it came in had this p/n 4529097 but the part in the box 5233906 then in smaller # 2397 is the part a t2 semc? the guy that gave it to me said he had some old omni stuff setting around but did not want to throw away. ALAN

[TurboJerry]

The # 906 is a T-2 cal. the boards are all the same. (you can make a T-1 comp into a T-2 comp just by changing the cal)

[5sp. mini]

thanks it set a code for act sensor i will have to dig my parts up and hook it up and see if my miles per gal. goes up. alan
