Fuel injectors?

[Sp00ner]

Would there be any advantages of installing new fuel injectors? Or is that just a waste without the right ECU tuning to go along with it? I was just browsing around on MSD's site and read quite a few pages of fuel injectors, fuel pumps, fuel pressure, and injector capacities. Is this anything that would help at all? Could it help even out the lean running tendencies of this engine at all? It even mentioned that running slightly higher fuel pressure would increase the flow through the injectors. Any thoughts?

bigger injectors alone would help very little. If you were to add an aftermarket/piggy back fuel computer with larger flow injectors there is more power that can be easily had with no other mods at all. Higher fule pressure would push more gas through the injectors but the car would soon learn and once again back off the amount of time the injectors are open.

This ECU thing sux... that's the entire stage1 upgrade for the SRTs. New fuel injectors and a new controller... 20hp. Someone needs to rip this thing apart ASAP....

Workin on it
Have a "mule" ECM to work from and gathering gear to attempt to offload the code.I was hoping the box was going to be directly compatible with "LS1edit" and some of the other tuning tools out there- but it's too different!
Right now it looks like it would take a lot of "luck" to just locate all of the offsets and prperly scaled values to make even a minor change (like eliminating/raising the rev limiter which is my first goal)
Anyone here have experience with Motorola BDM??

Motorola BDM? What is that a language or something?

[[DeVo]]

Motorola's Background Debug Mode (BDM) is the best known of the proprietary on-chip debug solutions. It defines a communications standard for interfacing to a debug core via a 10- or 26-pin connector on the target system. A host computer, running a BDM-compatible remote debugger, can communicate with and control the processor through this interface.

From http://www.netrino.com/Publications/Glossary/BDM.html

Sounds like a great way to get some stuff done with the ECU, assuming it's a motorola processor.

From my research our car uses the Motorola MPC565 32-Bit Microcontroller. The documentation for the microcontroller is downloadable here:

I did take some classes on programming for this exact kind of embedded system. Well, embedded systems in general, I still have my little circuit board, key, and crap. I can make LED's blink in pretty shapes!

^ ^ ^ i feel ya, LOL.
i don't know ... programmers speak a completely different language- one i do not speak either.
