Anyone ever consider a Megasquirt? Great ECU with a significant community.

Will it accept factory Fiero 2.8 ECM wiring terminals or must new ones be crimped on or spliced in?

Using a 7730 pigtail and a connector from an original 86 ECM, I built a converting plug assembly. I also realized that the car's built-in 160 baud interface (my added serial socket near the gear shift) needed upgrading too, so I wired up an 8192 from the MAX232 circuit found on the net. Figured I could get most of it done while Ryan is doing his magic on the memcal.
As for performance, HP & MPG do not concern me as much as smoother starting and response - and many here have said that the 7730 will help with those. I must say it was fun removing all the extra vacuum lines and stuff, and I would like to eventually plug all the holes rather than leave the cold start injector and other junk in place.

Sadly Marc (Gwain) has no more egr adapter plates and doesn't know when he will have time to make more.
Did anyone know/spot exactly what material these were made from? Grade etc?
Thanks for any feedback.

Making the egr adapter by hand is hard work! I am getting there though! All I have left is the half circular milling part....with no mill. Should be fun!

Can you cut one off a donor car? When I bought my 3.4L engine it had the digital EGR still mounted on the exhaust.

Started my 86 V6 up yesterday after completing the 1227730 ECM upgrade in this thread. Once the fuel pressure was up, it started easily and idled at the target 1100 rpm and sounds wonderful! Throttle response is better than ever before - This is a must-have upgrade for every V6 Fiero out there! I made a harness adapter rather than re-pin my loom (gave me options later on) - So a kit IS possible. The Knock sensor, digital EGR and evap canister valve control wires were all put together into a new loom, shielded and taped like all the others in the car - just looked neater that way..
Most thanks go to Darth (Ryan) from Sinister performance who programmed the memcal perfectly. I have many images but cannot, for the life of me, figure out HOW to post them here! (Which is hard to believe for a 30+ year engineer)[This message has been edited by DavidM (edited 10-18-2010).]
