Hi! Is the efi332 system working ? Is it anyone who can give an update on the progress on this system? Thanks in advance.

It was mounted behind the dash like regular ECM's Also have regular 730's with 3 connectors like a 749.

Each of the four connectors is a different color, and a specific connector is also available in different colors - colors such as red, yellow, white, blue, green, gray. The reason for all the colors is that each connector is keyed different - and the weatherproofing requires connector shells that exactly match the harness usage. Unused positions are molded shut, it is hard to add a pin where there wasn't one. Thus, if your '727 use doesn't exactly match a factory configuration, you may have trouble hooking up some signals. (With the '730 style connectors, it is possible to pull the pins out of the shells and move them around as needed.) As for a 727/730 4 cyl. MEMCAL, look for 1987 (only!) J-cars with the 2.0 "1" engine, or for a W-body with the 2.5 L4. - -- Ludis Langens ludis (at) cruzers (dot) com Mac, Fiero, & engine controller goodies: http://www.cruzers.com/~ludis/ ------------------------------ From: Paul Tholey Date: Tue, 16 Feb 1999 21:05:26 -0500 Subject: Re: Needed: 727 and 730 4 cylinder MEMCAL Doug, I only play around with the EFI stuff a very little. I don't even know what a 727 ecm is really. But I looked down, literally, and there is one leaning next to my Pentium. It is yours for $25. I think I bought it one time thinking it was a 747. I lost out, $25, and that is what I have into it. I also have a 730 ecm, with a complete harness. If you have any interesst let me know. Now for a more exciting question. What are you building?

I am offered a K&N air filter for Pontiac Fiero V6 1985-88/Firebird TPI 1985-92 for FREE, but since I have no idea how the filter looks, I don't know if I can use it on my application. What I'm looking for is a cone style filter or something similar.

I'd assume the GM intake was designed w/ an airbox (I think that the pre-'90 TPI had a MAF sensor in the intake, and the '90+ TPI didn't, but what do I know...I'm a VW guy) and the K&N is a drop-in panel filter. If you want a K&N cone filter, those can be had from Summit Racing, or just about any race shop or catalog. You could probably adapt a Japanese made (an off the shelf part) Aluminum intake to suit your needs. One thing to consider though...open element filters like the cone style are often subjected to hot air in the enging compartment. Since cold air is more dense than hot air, the oxygen content is greater in the same given volume of air...a better burn and more power output. That's the general theory most subscribe to. Cold air is better. So, most people fabricate a heat shield of some sort...or route a custom intake down below the car (and possibly get a ram-air benefit, but watch those puddles!).

Yep, but the thing is this specific filter is one of multiple choices as a price for winning a contest...so it's for free, but the choice is limited. Too bad.

The filter will sit in front of the radiator, outside the eng. compartment, so that's taken care of...
