chip differences auto. vs manual

Are computer chips different at all for lets say a manual 5.0 TPI car to a 5.0 TPI auto car?

The scenerio in question is that I have a TPI setup(wiring/ECM) from an automatic 87' 5.0 TPI Trans Am, and the cam I am using is supposedly from a 88' 5.0 TPI Trans Am with the 5 speed. I dont think it would be any different chip wise but had to ask.

I couldnt find an answer in my searches. TIA!

They are different for auto vs manual but I dont think its because of the cam. If you match up the cam specs and they are the same you should be good to go.

The cam you are using out of the 5 speed is a little more aggressive than the cam for an auto car (Different specs), If you are using the stock 87 MAF set up this will definitely not be a problem. Although there are some differences in the stock proms, the bottom line is your car will run fine with what you have.

Don't use a chip from a stick car in a car with an auto. The stick car chip will be doing shift light calculations which will then operate the TCC.

If you have an auto get an auto chip.

I am pretty sure you could use the chip that came out of an automatic in a manual (but your service engine light will be on all the time ,cause the ecm will be searching for the torque converter). But you can use a manual chip in a automatic. Works one way, but not the other.

I tried this it will not idle correctly. The IAC paramaters are different from manual to auto. The engine will run but you wont be happy it will surge.
