I am currently researching my computer options. I would like to use the factory computers, I can get the immobilizer programming removed from the factory pcm. I'm not sure how the bcm and pcm will react when I start removing modules from the bus though. I have been unable to find the needed info on the subject so I am just going to start experimenting on my car and see what happens. The backup plan is a megasquirt / megashift setup.



The PCM may complain that it is not receiveing bus messages. But, it won't or shouldn't affect the starting or operation of the car (depending on VTSS and SKIM info)...Technically speaking, you should be able to use the PCM (NGC 4) controller on it's own. I don't know what your going to do for a speedo option as that is a bused signal from the TCM/PCM to the cluster and ABS. Also emission DTC's will be an issue, returnless fuel system and it's associated pump module..Lots of stuff to think about...-Jason

There are a couple different places that can take my PCM and remove SKIM, so I think that part will be easy. Because the Autostick feature shows the gear selected in the speedo, I was thinking about using the factory speedo and tach and trying to make it work in a different housing, so I would need to retain the BCM for that. (That may not be as easy.) My only concern is a "no bus" error message in the cluster display if I remove the other modules from the bus. All the modules on this car are routed through the BCM so my plan was to just start removing modules from the bus and see if anything hiccups. (that's the nice part of having a complete running car). I downloaded a factory service manual for the LH cars, so I have all the wiring diagrams and data bus info I need to experiment. I hadn't thought about the returnless fuel line, but the fuel pump and level sender are run through the BCM so I may have to adapt the entire 300m fuel system in to the Fiero's. If all else fails, I'll go with Megasquirt for the engine and Megashift for the trans.

Disconnected as many modules on the PCI BUS as I could, no ses light, no error messages. Looks like I may be in luck.

Nice to see you've decided to try something unique! I hope to see it at one of the local meets when it's complete.

For the fuel, can't your just use a C5 Vette fuel filter/pressure regulator? Its designed for two fuel lines in (Feed/Return) and one line out to the injectors?

The fuel pump is part of an in-tank module with the pump, regulator, and level sensor all in one and is set to run at 58 psi +/- 5 psi and there is only 1 line out to the engine. Once I get the tanks out, I may try to make the 300m module work in the Fiero tank, which would simplify things greatly. Just depends on the depth of tanks I suppose and if I can get the Chrysler lock ring off and welded to the Fiero tank.

If the tank in the Chrysler isn't plastic. The 95 Neon I have is a metal tank and the 97 Neon is plastic.

The summer house projects are done, which means I can finally get to MY project!

Donor and recipient are in the operating room:



The teardown is underway! I've been looking forward to this for 2 months, this is gonna be fun!
