what is it?

 

6900 i believe... thats what it hits in first gear for me

 

not too sure if my guage is off but in my 89...it goes to like 7200 rpm...and 30 mph in 1st

 

it could, ive seen my tach go up to 7200 and rev limit, but usually 6900

 

so its just the inaccurate stock tach goin to 7200 , not the motor?

yes, honda factory tachs are pretty inacurate.

 

yea I can hit like 7200 and about 35

 

7200.

 

i think 6900 may be the cold rev limiter because my crx hits the limiter at around 6700-6900 when it is cold and then will go to about 7200 when warm.

 

7200

 

a 91 D16A6 has two limits: 6800 cold, 7200 warm

 

What are you dimwads hitting the rev limiter for when its cold?

Plain stoopid.

 

Not trying to highjack the thread but I am having an issue with my pm6 ecu.

Sometimes my rev limit is 6800 but every once in awhile I can rev to 7400 and thats the digital tach on the vtec controller.

Its very rare that I can hit 7400. With my last pm6 my rev limit was 7200.

And no my ecu is not chipped.

i know right....these motors are done making power by 62-6300 and these guys are going to 7k+ lol

 

my car maked power all the way to 7400 it doesnt lay down on the top end.

and its not like I beat all day long I hit vtec maybe 3 times a day
I need the gas

 

the only time my motor sees 7K is if i am burning out or something and the tires completely break loose and i dont realize how high it goes. Normally though the highest i will take it is 6500 and i have a sohc zc with a pm6.

 

well for me it was just to know... compared to my y7... im new to ef's end just lernin stuff still... what do you guys think i should do with my y7 (into a 91 Si with Si trans) keep the a6 ecu and harness and swap the a6 intake manifold onto the y7... seems like it would be WAY easier sensor wise... or keep my y8 intake mani on it and use my y7 ecu and harness?? anothing question...im going to buy oem motor mounts and then pick up Energy mount inserts, i know the 3 tranny ef tranny mounts will work for sure but what mount do i get for the driver side motor mount??

 

I make power up till my 7200 cut off.
I have a sohc zc short ram and full 2in exhaust all the way back

 

wait wait wait.

why are you running a pm6 ecu on a vtec engine? dont be so cheap.

no, no you dont. the car just doesnt slow down violently enough to convince your ricer *** that its done making power 1,000 rpm down the tach...

there is a difference in "making power to 7,200" and "shifting closse to 7,200" in first and maybe second gear with some bolt ons i could see myself using that 7,200. But seriously, on a stock cam the characteristics of a motor simply will not change enough to actually make power up there.

get it?
got it?
good.

because this is temporary until I can either sell my ltz400(atv) or trade it for a swap

 

PM6's can be modded for vtec. It's probably not the best way to do it, but there's no reason you can't run vtec off these ECUs. The only main difference is the lack of oil pressure variable for vtec engagement.

 

I don't know if my tach is just way off but in 1st gear my rev limit is 6900 but in second gear to fifth it goes to 7600. the ecu is the stock pm6 in a 91 si, i don't know, all the motor has on it is an intake, but it sure does scream

 

If it's a stock Honda tach then it is off. Also, look at a d-series dyno chart for an engine with a stock cam. You're not doing yourself any good revving up that high, even if the engine makes a lot of noise that high.
