I bought an 85 z28 it was a 305 tpi but was changed to a 350 with the ecm and tpi unit from the 305. Here's my question the car has a real bad lean condition i put 24 lbs. injectors in it and the problem is still there. do i need to get another ecm from like a 87 or what?

 

come on guys i need some help

 

You need to change the injector constant to match your injectors. Also you may want to upgrade to a 165 (86-89) ECM from the 870 that you should currently have (85 only). BW

 

if i were to post the number on the ecm could you tell me more about it.

 

yes.
