Feels like thread necro but in reality with forums these days, replies take a long time!

I'm looking at a Platinum Sport GM plugin myself for exactly that swap, helps that Australia is just across the pond from me so I can call them up for support.

From reading their documentation on using the 3800 with that ECU, it would really depend on what you're using as far as ignition components go - I'm assuming you want to keep the 3.4's DIS setup?

I sometimes take a lot of heat for saying this, but you can spend $1k-$3K on an aftermarket ECU and not get anywhere near the full features of the GM PCM (for maybe $100) that was designed and already tuned for the 3800 engine.

My distaste for hacked OEM computers is that they're undocumented by the OEM.

Any information is reverse-engineered by 3rd parties such as HP Tuners or similar. So the function of some tables can be misunderstood, and some tables may exist but not even be known outside of the OEM.

An aftermarket computer on the other hand is designed from the outset to be modified by the end-user, and is normally documented as such. There are no undiscovered functions.

I don't like working with undocumented black boxes... if that's your thing, all the power to you.

I go a step further and require not only documentation, but source code as well. No source code, no interest in using the ECU. I have zero patience for secrecy.

I second that, Amen!

Sorry if I didn't make this clearer, the Haltech Platinum Sport GM is intended as a plugin for 3800 cars, but it's a full standalone for anywhere a Delco of the late 80s would go... any reference to a 3800 is purely because the DIS setup on the Camarobird 3.4 is very similar to the 3800 setup - which the Haltech rightly handles more or less like a distributor since the DIS module itself coordinates firing.

The reason I was looking at the Haltech versus a hacked Delco or any of the myriad other options like MS/FreeEMS/LibreEMS is that the local tuners don't want to work with anything they're unfamiliar with - they like Links and Haltechs.

Just my $.02, reliability is factor to consider. These days, a bulletproof supply chain to keep counterfeit components out of production is critical, especially in an underhood application. The OEM's have this well in hand. Maybe Haltech does as well. If they can speak to and provide some detail to their program then they know the risk. If you get a "that's not an issue for us" response then they may not. Again just my thoughts..
