Going Hondata, probably.... Need advice!
Ok, it's been about a year of boosting on the drag-supplied "fuel system" of vortec 12:1 fmu, inline pump, and stock injectors. Fortunately, I now have the money to get some real tuning, and I think Hondata's the best/cheapest method. Here are a couple concerns/questions for you FI gurus:
1. What size injectors should I get? Later down the road, I'm looking to get 300-350whp out of my LS integra on pump gas. I'm first tuning on the stock block up to about 10psi or so, hoping to get 250whp, but later on I plan to build it to handle the 15-20psi for the 350whp. I've heard suggestions from reputable people as low as 370cc and up to 650cc.
2. What parts do I need exactly? Here's what I've come up with so far:
-OBDI, Hondata-chipped ecu
-OBDII--->OBDI harness
-Hondata program (if i get a hondata-chipped ecu, do i need this?)
-AEM, or other brand, rising rate 1:1 FPR
-Walbro 255lph intank fuel pump.
-GM 3 bar MAP sensor.
I want this car to be reliable as an everyday driver/occasional track use, but I don't need to be tuning this myself, or have any need for the datalogging, full throttle launch, etc. I think a barebones s200 system will give me what I need?
3. One more thing, my number 1 cylinder has a 35% leak in it. Should I address this problem first, before I go hondata or wait til it really becomes a problem?
tia, Ethan.

You don't need a AEM regulator (hell those things are unreliable, no one needs one), the stock regulator is a 1:1 rise rate. You don't need the 3 bar right now, you can wait on that if you'd like. Everything else looks good, I'd recommend RC high impedence 550cc injectors for your application and project goals. Good luck

What size injectors should I get? (550cc-720cc)
-OBDI, Hondata-chipped ecu--- (Yea)
-OBDII--->OBDI harness--- (Yea)
-Hondata program (if i get a hondata-chipped ecu, do i need this?) (You need the s200 blue box)
-AEM, or other brand, rising rate 1:1 FPR ----(Yea)
-Walbro 255lph intank fuel pump.---(Higly Recommend)
-GM 3 bar MAP sensor.--- (Yea stock map can only read 11.2psi)

for applications up to and even exceeding 400whp, with correctly sized injectors, I often ask the same question
