Ok so let me start out by saying that I am old school to the core. My car is a 73 rx3 with an old style street ported 4 port 13b. I currently run a RB Holley kit and nice free flowing exhaust. I have already purchased the beautiful E&J throttle body to take the place of my Holley. I have some brand new Injector Dynamics 550cc injectors from a different build that i was hoping to use to save a buck or 2. Thats about where im at currently. The car will remain NA, forgot to mention that earlier. From my research on this forum mostly, I am strongly leaning toward Haltech elite series ECU. I just wanted to see if anyone has any better ideas on this. I am totally new to stand alones and tuning in general so please keep that in mind and pardon my ignorance. I know i need a TPS which the E&J has provisions for already, I have full Speed hut gauges in the car already to include, wide band o2, water temp, oil pressure, I plan on getting the FFI crank trigger kit but was waiting to make sure it would work properly with the ECU i end up with... all advice is welcomed... Thanks in advance

 

My end goal is, better drivability, better fuel econmy, turn key starts, and hopfully a few extra pony's from the fun pedal!! lol

 

i think all of those are possible. i would actually put the wideband on it now, and see what AFR's its running, and you then will have a known good AFR target. you will see there is enough to play with that anything you can do to make the task have smaller easier pieces is good.

pretty much any ecu will work ok, i'd look at a few instruction books, and the software and see if you think one is easier than the others.
