how do you guys feel about mega squirt?
reliability
tuning
i guess the overall install process from ripping your harness out to getting your car running..

im trying to choose between haltech and mega squirt and i cant really decide.

also what was your over COST of buying and installing your mega squirt.

 

Reliability and tuning have been fine, as long as you know how to tune in the first place (or are willing to do a bit of reading and experimentation) MS is much more of a DIY project, whereas a haltech is typically used in a much more "hands-off" fashion.

The MS2/V3 was about $300 for all the components, probably another $75 after the DIYautotune wiring harness, soldier etc, and then $200 for the Innovate LC-1 wideband sensor and controller, plus whatever you want to spend on gauges, and if you need a serial to usb adapter

 

The reliability of the Megasquirt is directly proportional to the skill of the installer. In fact, this is the case with many standalones. A Haltech will end up unreliable and unusable if wired in with old speaker cable and masking tape. Same with a Megasquirt.

I find tuning the Megasquirt to be just as easy, if not easier, then most other ECUs. Some of the settings are a bit obscure in their meaning but there is documentation available for everything. And you can always ask the forum.

As for cost, I always tell people to budget at least $800. Sure, it can be sometimes less, but more often then not, it is more. The Megasquirt controller may only be $450 though you need to remember that you need to buy wiring supplies, a wideband, connectors, etc. And send your injectors out to cleaning while you are wiring things up!
