I have no information about anything in Cali, so you're on your own there to figure out what will fly and what won't, but there's not a ton of options for our cars, but you don't really need a ton.
How is the car tuned now?
Moates was in the game for awhile, but it was a chip added onto the factory ECU, so it was a bit limited by our ECU's performance. They're not available new anymore, so finding one secondhand is the only option there. Should be low on the list.
Microsquirt / Megasquirt options are out there. PimpXS is a Megasquirt system, EFISource has a SN95 option, both pretty much plug-n-play. Megasquirt stuff is $900+, Micro is $550. Same basic idea, but Megasquirt has a lot more I/O options.
Holley has a handful of options, and I know Anderson has a plug-n-play option for their Teminator X, I think it's around the $2k mark.
Do you have a tuner lined up to get the car ironed out? Any competent tuner should be able to work with either Squirt option or Holley, but some are picky and some have their preferences so getting a tuner lined up that you trust might be the best option in deciding which ECU to go with.
I'm a cheap bitch so I went with the Microsquirt. It will do everything I need to do - H/C/I and Vortech on a relatively stock car. Nothing trick, nothing crazy. Holley or Squirt are going to go to be Speed Density, so MAF will be leaving the chat and you will have to run a wideband O2 sensor to them as well - relatively minor deals for both.
