That's an easy question: You want to use the TBI setup from a 1987+ 4.3. No need to reinvent the wheel. Some 85 and 86 4.3's also came with TBI, but the 87+ ECM is much better understood. - -- Ludis Langens ludis (at) cruzers (dot) com Mac, Fiero, & engine controller goodies: http://www.cruzers.com/~ludis/ ------------------------------ Date: Mon, 04 Oct 1999 10:25:29 -0500 From: steve ravet Subject: Re: Fuel injecting a 4.3 > Date: Sun, 03 Oct 1999 16:30:43 -0400 > From: Darren Floen > Subject: Fuel injecting a 4.3 > > Hi,i'm new to the list.I'm fairly inexperienced with electronic FI,but > i'd like to install a throttle body setup on a 1986 4.3 chevy engine.I'm > swapping this engine into my 85 Toyota truck.What type of setup would be > best?I was thinking of a Holley Pro-jection setup,but I have heard some > bad things about them.I was thinking of using the 2Di,closed loop setup. > Could i use the injection setup off say a 3.8 liter buick?Would it be > able to compensate for the larger engine? > > Thanks very much for any replies,and please cc them to me at > dfloen@xxx.net Darren, if you're interested in the GM approach (should save you some $$$), then get a TBI system from a 4.3. They shouldn't be hard to find, almost every S-10 from late 88 on has one. Also Astro vans, and maybe some full size pickups? Anyway, it doesn't get more bolt on than that. No reason to use the 3.8 and worry about tuning and stuff. Also get the service manual from whatever vehicle donates the EFI parts, that'll help with wiring. - --steve > > Darren > - -- Steve Ravet steve.ravet@xxx.com Advanced Risc Machines, Inc. www.arm.com ------------------------------ Date: Mon, 04 Oct 1999 13:40:10 -0500 From: "Jack E. James" Subject: Best EFI Choice? (GM, EECIV, Mopar) Group, I am just starting out to convert some older motors (Ford 302, 460 for now, but have 454 Chev and 390 AMC planned later, all in various states of street/strip tune) and am looking for choosing a system to "standardize" my investment of hardware, software and "education". Would anyone offer pros and cons for the major systems in wrecking yard availability. Is there any internet sources that consider the merits of one system over another for a hot rodder? Some items I believe important in choosing are (order may vary): 1. loop processing speeds, 2. "tunability" (should include backyard build it yourself kits or modules for processors), 3. Software decoding, the understanding of control locations for many years of availability. 4. Costs of external tuning, software and adapters for making processor modifications. Any suggestions welcome, Jay ------------------------------ End of DIY_EFI Digest V4 #560 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
