3.4 ecm question

Quick question. If I swap in the 3.4, can I also swap in the ecm to use the DIS? Will it work with my 91 gauges, etc.? Thanks

Oh and yes I searched but all I found was info on using the 2.8/3.1 intake with the distributer.

I was tossing around the idea. But I just found that its doable but there would be a problem with my VATS system. Any other problems I missed?

vats might not be an issue, being that your car already has it & my 94 also has it. Dash wiring should be cut & splice in to your guages.

Now there he had to do all his wiring but said the 3.4 & 2.8 from he firewall to the intrenal harness its the same. I'm not too sure about that.
