hi all. I was trying to search about these two ecu's and i couldnt get a solid answer, so i am asking you all now. here is what i am trying to figure out.

I have a 91 si with a pm6 ecu. I have a zc installed and i want to use my brothers PG7 ecu in my car so i can have a better fuel maps and whatnot.

But will my pm6 ecu work in his 87 integra if i swapped his ecu into my car? lol his car just sits and he doesnt drive it much at all. I just wanted to know if my pm6 ecu will work in his car with no problems. Just something i have been trying to search for but cannot find a solid answer. (or i am just not searching right) Any hel would be appreciated. Thanks Justin.

 

a pg7 ecu from a 87 integra is no good man 88-89 5speed are what youre looking for

 

well im not exactly sure if its a 87 im gonna call and see. lol what is the difference from a 87 and an 88-89 arent they the same ecu's?

 

I know for a fact 87 is different, I dont even think it will work, if it oes work then your car will run like ***.

Search for a minute, another person on here bought an 87 pg7 and had no idea why his car sputterred and stalled, found out it was an 87

 

alright thanks man. i will look into it.

 

are there pyshical differences in the 87 and 88-89 integras? i know one has wrap around turn signals, and the other has smaller amber bumper turn signals. the one my brother has is the smaller amber turn signals. i dont know if this helps at all.

NO.

The 1986-1987 Integra uses a mechanical advance distributer and is missing a couple of sensors. I don't even know if the car would run with a PM6. But even if it would, it would run like crap and throw lots of codes. You might try going to some pick-and-pull type yards. Although the 1988-1989 ECUs are fast sellers, nobody wants the 1986-1987 ECUs. So the right ECU should be easy to find.

 

86-87 had vacuum advance distributor, 88-89 is electronic.

 

what if it were a 88-89 would the pm6 work in his teg

 

I see no reason why it wouldn't if the PG7 works in your car.
