are they the same?

like when u do the dpfi to mpfi conversion do you change ECU's


are they exact?

 

when you do the conversion you have to swap ECU's aswell

 

ok.

just to make this clear this wasnt a MPFI SWAP TOPIC.
just use that as an example.

 

hey thanks for the heads up

 

just dont want people doing a "use the search" button on me.

this is about chipping the ECU.

 

if you want one pre made try http://www.hyperducktuning.com

i think they'll also chip an si ecu if you send it to them

 

from what i've heard, you cant chip the 88-89 Si ecu's. but you can with the 90-91's. i havent heard anything on the chipability of the dx ecu's, but good luck

keep us updated, as i too am curious about chipping a dx

 

im talkign about a 90-91 ecu's
pm6 i believe

so i am guessing i need a si ecu.

 

Yes you need an Si ECU.

 

just like doing a dpfi to mpfi swap i suppose...

 

I have an 89 Si PM6 ECU if your interested.
