I'am having trouble finding the answer to my questions mabey you guys can help me out a bit. Okay, I have a P28 ecu that is chipped for ls vtec NA, and the engine set up that I am building is a ls vtec turbo. Iam going to boost 10lbs. and i have 550cc inj. I already have the hondata s200 unit that has the boost option with stage III. I was wondering if i can hook it up and have it run as is until I get it tuned. Now, I am only thinking that it would work because its already ls vtec ready. I'am not sure because for 1 I am not sure how the s200 works with the ecu. 2. I have 550cc inj. Thanks for all the info in advance.
