Just curious what rpms is your vx tranny reading in 5th gear going 60 mph? I think maybe my rpm gauge is off. When im going 60mph in 4th its around 2000 rpm and in 5th it says like 1600 rpm is that normal for a vx tranny. The reason i asked was because i got my p28 street tuned for my d15z1 and vtec set at 3500 rpms when my rpms hit 3000 the check engine light comes on for vtec (b cuzz my solenoid is bad got to get it replaced )but is my rpm gauge off like when i hit 3000 rpm i actually at 3500 rpm or is that just how vtec works it detects before 3500 rpm? silly question just curious if i should go get a new ex/si cluster lol Thanks

 

hondas are known for the tachs being slightly off. dont worry about anything.

 

damn i need 1 of those trannys i got a 92 vx but it has a dx tranny i believe and a p28 (bought it like that) and at 70 mph it revs at 3200 rpm that sucks to cuz i drive an hour 1 way to work!

 

Yea i bought mine like that with p28 but my mpg sucked with out that 5 wire o2 so i just got mine street tuned and deleted that 5 wire o2 all together,the vx tranny is pretty cool since i dont street race it saves me gas and keeps me out of trouble lol

 

For real thats good to know but i might go get another and see i have to get a new gas gauge any way ill just get the whole cluster

 

The normal "VTEC" cutover for a D15Z1 is at 2500 rpm. That's the point where it goes from 12-valve operation to normal 16-valve operation. It's not like regular VTEC on other Honda engines.

 

Yea true but mine is set at 3500 to save gas on low rpms i never go pass 3500 driving normal

 

I'm doing 2400rpm at 75mph on the speedo, 70mph corrected on my GPS! VX tranny has teh LOOOOOONG gears!

 

Cool thanks so i guess i am 500ish rpms off as i expected ill take my rpm needle off and raise it up 500 lol

 

If you're doing 1600rpm at 60mph on the speedometer in 5th, you're on point bro.

 

I stand corrected. I checked today and was at around 1900rpm going 60

 

Thanks for the info,Yea for piece of mind,i went to the junk yard and picked a cluster up for 16 bucks so yea mine is around 1900 to at 60 in 5th my other was way off but now this cluster i bought the mph needle gets stuck on zero mph and i have to hit it and it works and some times it jumps up like 5mph my other mph cluster did that to but didnt get stuck on zero mph like this one guess ill go hunt for another cluster and pray its perfect lol

 

Yea the gears are super long,i wonder if boosted d16z6s use them lol

 

that would be fun
