87 ecm upgrade

[ryan77]

What is involved to upgrade to a 87 ecm on a 84 grand national

 

[Boost231]

87 computer, and a new chip is about it

 

[turbonut85]

You need the following:

87 ECM
87 chip (or custom chip by Turbo Tweak) ---recommended---
87 MAF or LT1/LS1 MAF and translator
87 IAT sensor/wiring (or get a TT chip and have Eric turn this function off)


Hope this helps. ---Keith
