Can I pull an entire EFI system with the ECU and adapt it too my 600cc motorcycle engine? It seems that so much can be done but I don't know my head from my arse when it concerns electronics and computers. If this can be done, what is the best way to do this? I was thinking of just going to a wrecking yard and pulling the entire system off another 4 cylinder car. The manufacture doesn't matter I just want maximum performance, thank you in advance for any help. =================================================== While it is possible to adapt a vehcle's EFI system to a motorcycle application, I think that based on your comments I wouldn't recommend it. An EFI system doesn't automatically provide maximum performance, it has to be developed specifically to do so. One of the biggest things you're going to have to figure out is how to adapt the system to an application which has 1/2 to 1/4 the displacement that it had originally. This is certainly going to require some level of expertise in electronics and computers ... There are motorcycles that come with EFI systems as well ... I've got a BMW 1000cc which uses a Motronic system, and I know that there are others. I'm sure that it would not be likely to be as inexpensive as would be likely from an automotive wrecking yard, but it might be closer to what you'd need. Another suggestion would be to start from the ground up. There is an associate project called EFI332, from which a system could be built to control the fuel injection (and ignition for that matter) for your bike. Here on this list in the past few weeks someone posted that they had created a hardware-based EFI system that might be a good starting point as well. I don't mean to dissuade you from your quest ... I've actually got an EFI332 kit I want to make work on my Beemer myself ... I just want to make sure you have a clear idea about what you're getting yourself into before you start spending any money ... Have fun!

Hi All, I've noticed a fair number of different postings regarding FI controllers from stock automotive units to the roll-your-own type. I'd like to tap this rather wide body of experience and begin a dialog on engine diagnostics. In particular: a) the engine refuses to start i) What sort of diagnostics do the 'stock' units provide? ii) What sort of diagnostics do the homebuilt or after market units provide. b) engine starts and runs for 30 seconds (or 5 seconds or 1 minute...) i) As above. ii) As above. c) engine runs, warms up properly and then suddenly dies at cruise speed (say 2500 to 3500 RPM) i) as above. ii) as above d) engine runs but dies at full power or refuses to reach full power. i) as above ii) as above d) engine runs but enters 'limp home mode' i) as above ii) as above iii) What constitutes limp home mode for a FI implementation. e) engine starts and runs but then suddenly develops a 'wicked' idle. Perhaps lots of hesitation to move from idle. Obviously, MAP verse MAF systems will create different diagnostics but what I'm looking for is information that will help a mechanic diagnose the problem without needing a complete laptop PC. Some systems use a lamp and create a flashing sequence with 'fault codes'. What sort of codes would be useful? I am assuming that some basic engine troubleshooting techniques are available like: is there fuel; is the battery above the minimum specified voltage? etc. Assuming the engine controller works properly, what sort of information could be provided to help someone diagnose a damaged sensor etc. Thanks, John Dammeyer ------------------------------ Date: Wed, 22 Sep 1999 22:24:26 -0400 From: Jeff Martin Subject: RE: DIY_EFI Digest V4 #539 I was wondering if anyone could point me towards a place that had info on Isuzu and its throttle body injection that they put on the 4ZE1. I have a 4ZD1 that I would like to get rid of the carburetor and put the aforementioned fuel injection system in my Trooper. Did the intake manifold change at all when they changed the fuel system because I was thinking that I could just bolt the throttle body up and put a high pressure fuel pump on the line and figure out the wiring to make it work. If anyone could help me I would thankful. Also I have in mind a CJ-7 with a rebuilt engine but a tired carburetor that doesn't work the best. I was wondering if the intake manifolds of the 4.0 liter high output engines of the Cherokees can bolt up to the block of the 4.2 liter. I know I am asking a lot here but could you show me where I could find out this stuff. The wiring harness in the CJ is worn out and I figured a total swap of the wiring harness would also happen. ------------------------------ Date: Wed, 22 Sep 1999 22:57:30 -0500 (CDT) From: eclark@xxx.com Subject: CS-144 Alternator Not directly diy_efi but its related. I have a CS-144 Alternator on a 93 LT1 that I put in my '66 Impala. The f-body that it came out of has a wire on the L terminal that hits the guage cluster. Is this the wire I should run to my 66's Generator Light? or is it the F terminal. Looking at the diagrams in my helms manual I am led to believe the the L terminal is for a guage and the F terminal is for a light, but I dont know how to tell. If anyway has done this type conversion I would appreciate some insight. - - Eric 66 Impala LT1 ------------------------------ Date: Thu, 23 Sep 1999 18:22:00 +1000 From: Peter Gargano Subject: Re: DIS info > Date: Wed, 22 Sep 1999 12:16:45 -0400 > From: Chris Conlon > ... > > From: "Scott, A.
