id like to know which haltech i would need to run on a '90 vert with a 13btt = 3rd gen motor (just so you dont get confused). anything you guys would like to share with me about this swap would be much appreciated!!!

 

I would recommend an E6X. It is the most common ECU for fuel and ignition control offered by Haltech.

 

If you are going to use the haltech to control the oil pump as well, get the E8, it has better control in the soft.

The e8 will also let you go full sequential ignition and injection, wearas you'll have to run batch with the E6X. The E8 Is only a little more expensive, unlike the jump from e6x to the e11v2.

 

This question has been asked plenty, its basically a comparison of the options you need vs. the budget you have.

What do you plan to do and how much can you afford to get it all done.

E6X or E8.
