Hey, I've been using hondata a lot recently after I bought a new r18 project but I wanted to boost it right this time. I do know that it has VTEC but it's not the traditional VTEC people think. I was trying to play around with VTEC and was driving my car today when it was finally bogging down. I remember setting my "ignition high & fuel high" to 0 because I have never been able to activate/satisfy the VTEC conditions. I went home and saw that it was finally going into VTS.

My point is, does hondata keep the cams names correctly when using the R18 VTEC as ignition high and fuel high is for the high cams? I notice while datalogging it always uses the ignition and fuel low no matter what, even at WOT the VTS never activates, because I thought VTEC was for economy.

I would love to know some info about it because I want to actually make it somewhat fun before I boost it with some new forged rods.

Such as should I actually make VTEC 2100 - 7000? or keep it low as I think it should be. I need a lot of input thank you below is my datalogs and calibration.

VTEC on an R18 is not for power and is only for swirl in the cylinders. You should not modify how VTEC works as it will not increase power like traditional VTEC engines.

That's what I thought, just making sure because I noticed that the tuned maps and stock maps looked the same for ignition high / fuel.
