#Tuning factory ls ecu pro

I began with a reprogrammed factory ecu and not one but three different tuners.įinally said enough is enough and pulled the trigger on an MS3 Pro Evo. No offense taken if you don't trust some guy off the internet though. I've got a little more cam than yours but it should certainly get you started. Just more of hassle/headache in my opinion.Įdit: Forgot to mention, I'd be happy to send you my tune I have for my LS3 T56 C3. No doubt this will work, and being an OEM computer its certainly going to be robust/reliable/durable, but you're very defined/limited to what the capabilities of the computer are, and sometimes the software to edit these computers is kinda of 'lying' to the computer to make it run well instead of actually just being calibrated correctly in the first place. I'm not a huge fan of using the stock computers with HP Tuners.

The only cons that I can see are that because its so flexible/so capable, it can be a little easy to get lost in it all and lead your self astray, and that there my not be as much tuning/technical support on the other end of the phone (For example, I'm guessing Holley has people on staff for those kinds of things). I think you can even edit the firmware if you want to (but I don't see why you'd ever need to).

Its packed full of features, all the basics like cold start enrichment, close loop fueling correction, etc, and plenty of awesome extras too such as high and low current, PWM, and 5v reference inputs and outputs that you can assign however you want. Its certainly proven itself as it's used in plenty of race cars and street cars. If you're not familiar with MegaSquirt, its an extraordinarily flexible engine management system that can be used on nearly any type of engine. Its a bit more affordable than the Holley systems (which are also good in my opinion). Extremely easy to use, and it has a self tuning feature for VE that worked incredibly well for me. I went with an MS3 Pro EVO from AMP EFI and used their drop-on harness kit too.
