Here is my set up. JDM 98 GSR B18C in a 96 cx hb. I have IB probe 12:3:1 pistons, IB beam ultralite rods, skunk2 stage2 camshafts, valves, springs, retainers, cam gears, DC 4:2:1 header, Fsudo full cat back with OBX high flow cat, cold air intake, prelude injectors, AEM fuel rail and regulator, NGK spark plug wires and some $6 each spark plug. AND HERE IS MY QUESTION.....which HONDATA model is best suit my motor??? I heard of Hondata but havent done any research on them. I check their site and found that they made HOndata chips such as the s100 and s200 and they also made the actual ECU(which cost a lot). any help is well appreciated. by the way, what kind of HP gain do I expect from from this set up and what 1/4 time? I couldnt wait until April 4th, first race of the season. thanks guys. time to upgrade my signature!
