i wouldn't call you a liar mate.
I'm pretty sure the Zeeltronics stuff does accept a tps input and does 3D maps, as i was going to buy one for my VJ21 an wondered if it would be worth it as it was an early K model without a TPS.
Yeah all the factories would of invested a few quid in setting them up, no doubt about it, and the Honda one is very good, no doubt. I'm not arguing with that at all.
Just maybe it could be improved upon for certain situations, how much would it cost me for a HRC PGM?
