can anyone suggest the best options for a stand alone ecu and a boost controller for a sr

 

I've seen quite a few people running GReddy e-Manage or even a S-AFC, but those are only fuel management and can mess w/ a lot of stuff in the ECU if you're not careful. Here's a few companies that'll do the job for ya:
SDS
MoTeC
Haltech
Apex'i
F.A.S.T.
AEM
Most of these also offer boost control and such. Go with the EMS that is closest to what you'll be doing. 90% of the features on AEM, most people won't use lol.

 

Got 2 agree with Cossey AEM EMS is def the way to go if u want standalone and can afford it. IF u do it do it right and get the UEGO wide band O2 sensor and a/f ratio gauge. And if that is too rich 4 your blood check out Microtech, another good standalone for a little less. The best place to check out microtech is centralfloridaturbo.com they put it on an sr and made 501 whp! Check out the dyno video its BADASS!!!.
