Hey guys,

I was wondering if anyone can help explain the benefits of swapping out an OBDII w/ an OBDI ecu.

I have a 98 R with the usual I/H/E and pulleys. I also installed a VAFC two years ago and have it set to defaults. I've been told (source not so reliable) that the expected gains from tuning the VAFC would be alot greater if I switched to an ODBI ecu. Also that I should realize greater gains with my combo if i switched to OBDI. Is any of this true?

I plan on doing cams in the distant future or even SC. Not quite sure yet but I'd like to extract as much as I can from what I have installed now.
Would a p28 or p72 benefit me in any way? What about p28's that Kenji sells? Are these static?

TIA
