So basically I need a small tutorial from the very beggining. I know nothing about these EFI systems, and after a long while of trying to find info on my own I figured I will pop a Q. I have a 1991 LS B18A OBD0. I have socketed/ chipped my ECU, but what will I need to tune it once I want to go bigger than IHE? I will not be tuning myself, I'm going to pay SpeedFactory the big bucks when the time comes for a dyno tune. I see all this Crome, Hondata, Neptune stuff and realize (I think) it's not just a program, but actual hardware that is (Needed?) to tune a car. Also it seems like I must do an OBDI conversion to get a real tune? What is the baseline stuff I will need to get an awesome tune on my car? Thanks in advance for the help! Kyle

 

You need a chipped ECU, hardware to either real-time tune or burn a chip, and a software package to tune with.

If you get a NepTune RTP package or a Hondata S300 you simply install the hardware in the ECU and then tune it with the software.

Here's an install video of how the NepTune RTP works.

I think you are telling me what I need to tune myself? I just want to take the car down the road to speedfactory... Do I have the correct ECU, Talk to me like I have no idea what your'e talking about.lol In truth I really don't... Thanks

 

Why not call speedfactory or stop buy their shop and talk to someone about having your car tuned. That way you can begin a relationship with your tuner. That's what I would suggest. Ask them the same question and they will be able to tell you what they require.

 

If you get tuned by a tuner you'll need a chipped ECU and that's it. Definitely give them a call to see if they have any other prerequisites for getting tuned.

 

So Just the 28 pin socket and a chip for them to burn? =] That makes me excited.! Or do I need it chipped with like a neptune or hondata board, which will cost several hundred$ to do on my car? What if I want to tune a turbo, or nitrous? I think I will pay a visit to SpeedFactory next week. I need to have a new exhaust made, I destroyed my Tsudo muffler...

 

If you want to tune yourself or make adjustments yourself later on, you'll need more hardware and software.
