My p28 ECU already has the 2 sockets. I'm debating over the spoon chip where VTEC engages at 5,100 and the mugen where it's at 5,700
I know that's not the only thing that is different in the two chips but which one would be better for my setup? Any others besides those two?

Right now the chip that is installed is for a b16 setup and vtec kicks at 4,600 eats gas like crazy

 

um, d15b7 is a stock non-vtech engine...so how why have a vtech chip if engine is no vtech

edit: oh, sry didnt see mini-me swap

 

Okay so I unplug the vtec wire from my ECU to see where power stops droping.
The small cam lobes pull all the way up until 6,500 before I feel any lag in power. I'm thinking about getting the mugen chip which sets vtec engage to 5,700.
That sound about right? Or could I get one that kicks vtec in at 6k or something or would that be too high?

 

vtec engment higher then 5k on your stock/mild SOHC will equal more losses then gains.

there are much better alternatives as far as chips, for SOHC. check my sig

 

Are you sure? Stock vtec engagement for d16y8 is 5k+
by the way, nice site My car looks like the one on your logo.

 

Searching around, I seem to only find chips for d16z6 and d15b vtec and none for d16y8.

 

dyno shows clearly, the power drop off past 5.2k rpm, check it out, for more info and dynos of the chips we have done

hmm I guess I'll just get both chips to see which one is better then just sell the one i don't use

 

*bump* as of right now, I'm running without vtec, the cars feels like it pulls a lot harder only that power can no longer be felt pass 6.5k

not trying to be mean but its vtec not vtech....vtech is a company that makes phones

 

this is soe good info. gotta bump for reference

 

sorry but i just couldn't resist

 

Could the higher compression be or the advanced 2 degrees on my cam gear that I was told to run be affecting the wierd performance?

 

the proggie that i ran and ran on my buddies ECU that worked very weel was the JUN prog. It pulled very hard and was not bad on gas mileage like mugen or spoon.....i ask my buddie if he still has teh dyno sheets. but he made a few more usable and peak HP with the JUN... from what i have learned sohc's dont like to run rich (unless boosted) FYI

 

hmm when was the vtec cross over? If I'm going to get a Vafc could i keep the map from the chip but change vtec cross over using Vafc? or at least mimic the map from the chip with the afc?
