I'm curious as to how many people have done the 7730 update and what other changes have been done to the engine (stock V6 vs. DIS or even different blocks/intakes etc.)

Should you decide to go with the 7730 ECM, the Georgia Fiero Club sells DarthFiero's EGR adapter plate. It's needed to install the digital EGR valve.

I was using a 3400 block so when I did the conversion, I used DIS.

Just what does this mean? An advantage to using the 7730 ECM in a Fiero application is the drivability and response time of the engine improved significantly. Just what is sirnificantly mean. Throttle responce? Faster? Better MPG? Easier starting?

For ANY ECM swap - if you can't get the tune right, you may be worse off than before.

I have all the parts needed for the 7730 & DIS conversion. Only problem is I need the harmonic balancer machined with slots to trigger my homemade crank sensor setup. No machine shop wants to bother with such a small job. My engine is an 86. I think "ConvictedRedneck" had a similar delima and resorted to using a #8 ba$tard file to cut the slots.

I heard there's a motor-head machine shop about 30 miles from me that would be glad to look at the spec's I need and do the machining. Other than that I have everything sitting in a box ready to begin. Should be a nice winter project.

I have collected all the parts to do the DIS upgrade or restore(?) on my 3.4L. I'm just curious about how many otherstudents have been done.
