fire order

[walkdawg]

I have just put a 351 w efi in my 89 with a 302 efi the firing order is different. I was wondering do you need to move the wires around for the fuel injections I am still using the computer from the 302

 

[Minnesotabronco96]

i got a rumor on that that the computer would want to put less fuel in the engine because it still thinks you have the 302.

u need to get a 351 efi computer

 

[Minnesotabronco96]

and use that wiring harness from the 351

i did the same and i used the same harness that the 302 used..only difference was that the 351's have no nock sensor so theres an extra plug that just hangs there on the passengerside back of the block

The knock sensor is not the only difference the injectors are pinned different from a 302 to a 351 due to the firing order and some of the 302,s also have a pressure sensor on the power steering pump to bump the timing up when it goes under load . /emoticons/[email protected] 2x" width="20" height="20" />
