Here is my problem and I appreciate any feedback on the subject. I have a 97 GSR. AEM CAI, DC 4-1 Header, Thermal Axle-back. In the future, ITR cams, cam gears, 3 angle and minor port work, upgraded TB. That is all my plans consist of. I want to have control of VTEC engagement, a/f, redline and timing. I will dyno tune the whole thing now and when the head work is done. What is my best solution. Can I get good tuning witha VAFC and not worry about redline and timing or should I go Hondata. If I go that way what exactly do I need; obd1-obd2 adapter, ecu what? Would getting a adapter and a Skunk2 ecu be simpler and cheaper. I have never seen a chip OBD2 ecu. Can it not be done? Please let me know. I am totally lost with all this stand-alone and OBD stuff and I'm hoping to get a grasp on it with this post. As always value is important, not so much it being cheap.
