I would prefer that too. But it seems to be too difficult. It's looking like a full strip of the chassi, despite being a lot of work will end up being less time consuming,They certainly get more difficult every year.
Fundamentally, you need to keep the body electronics stock and functioning,
Exactly. It's looking like that.while tricking them into thinking that any missing components are indeed there and functioning correctly either via basic circuits that will provide the steady-state "on-line" signal they are looking for, some sort of artificial variable signal that you create yourself (arduino boards are popular for this,) or bastardizing the donor car circuits. All of this is very tricky and time consuming
One more reason to go the full chassis strip way, I would say?because it's pretty much a crap shoot as to figuring out what needs to see who when, and it'll be different for every chassis, even different year to year between similar cars. And just because something works in the garage doesn't mean it will continue to work with a car in motion.
But a stand alone ECU will not be need if I carry over the engine donor ECU, right? Which is what I would do if doing the full chassis strip.The TBW example I referenced earlier for example, may work fine until the car detects slip, at which point it tries to command a different throttle position, is unable to do so, and goes into limp mode.
Once you get that done, the rest is relatively easy, and includes:
Implement and calibrate/tune a stand alone ECU for the engine, attempting to use as many OE sensors as possible.
Again not need if I fully strip the chassis and use the engine donor gauges on the dashboard?Use some sort of aftermarket configurable dashboard or generic gauges, piggy backing the ECU input/outputs for things like temperatures and engine speed, and harvesting others such as vehicle speed from a source you come up with.
Ok. Although I might ditch things like power windows, power locks (it's a door car anyway) power mirrors (if it has) etc for shaving weight. I want to try to make the car lighter.Re-wire the rest of the car so that you can have things like a radio, power windows, power locks, dome lights, trunk releases, HVAC, etc via something like a Painless kit.
