7730 ecm installs
« on: November 24, 2015, 10:39:46 AM »
I'm offering 7730 ecm swaps as a service now.
I'm still working on pricing because there are a few options that open up with a 7730 swap, such as:
Code mask,
Dizzy vs dis ignition,
Cooling fan control,
To egr or not to egr and digital control,
Digital cruise control option.....

Tuning is part of the package as well, so you'll have a fully functional vehicle when all is said and done.

The wiring is labor intensive and a pain the the rear, so the costs are high.

Any suggestions and feedback are much appreciated herein.

One of my upcoming projects is to install a 7730 in my 4.9 car. Sometime.
If you happen across a 305 or 350 TPI MEMCAL, I have a V6 MEMCAL I'll swap with you. (The knock modules are different. I'd prefer to start with a V8 module, even though I may not even use  a knock sensor.)

Variations on a theme were some of the questions I had.  What's operational in a base install?

If just the car is delivered to you, do you provide these items and what's the additional costs. 

7730 harness connectors to convert from stock connectors.
87 or 88 Duke ECM tray to mount 7730.
DIS coil pack and module. 
DIS oil pump drive plug to replace the distributor.
New plug wires since DIS would require a longer set of wires.
Make knock sensor operational.  This is assuming a 3.4 since it has the knock sensor where the 2.8 would require aftermarket units (expensive).
Make ECM control fan.
Delete vacuum EGR and provide Digital EGR Valve and adapter.
Digital cruise as opposed to stock cruise control. 
Will stock cruise work with the 7730?

Love my Fieros, S-curves and speed.
It's what driving was meant to be.

I wouldn't recommend running a knock sensor on a 2.8.  I spent mucho time trying to get it to work, and finally did, but the valve train is so loud that the setup continued to retard under false knock constantly and wasn't worth the trouble at all.

I would say a base install is:
7730 Install Repinning
Modify existing ecm tray
Ecm fan control
Digital egr
Dizzy setup
Factory tune

Factory cruise will work with 7730

If all items are supplied by you, along with the car, just labor and tuning costs will apply.

Dis would be an option and would be extra,
Digital cruise would be extra,

Fresh baked brownies (no nuts) Will warrant a discount and extra attention to detail :)

Raydar, I'll keep my eyes open for an 8 cyl knock cyborg thingy
