silvertop - Need more rpm

[munkey]

G'day,

Id like to get another 500rpm out of my 20v before it hits the rev limiter as i feel there is more power there.

Is there anyone that can get into the computer to up it abit ?

[Sam_Q]

first up are you hitting the proper limiter or the lower limit without the speed sensor, basically whats it stopping at?

Either way you should get that ecu and bin it, it's a pile of junk

G'day,

I think its stopping at 7500, ill have to check..

What do you recomend i replace the ecu with?

[Sam_Q]

7500? you haven't connected the speed sensor input have you? I don't know much about ECU's just don't get a wolf, they have issues reading the crank angle sensor sometimes. Also this might help:

keep in mind my knowledge on the subject is very limited

Its revs to 7700 RPM when held flat to the deck and just go's bap bap bap bap bap bap

Ive had nothing to do with the ''speed sensor input'' and dont know what it is.

Whats this ''proper limiter & the lower limit'' you mentioned?

[Sam_Q]

ok lets go back to the start, what's the engine in? tell us what it has now and show pics if possible

I thought silvertop's had a limit of 8500 as per factory and blacktops were 9000rpm ???

Factory rev counters are not accurate enough to tell much,
some are up to 1000rpm out a 9000rpm,
so going off that is a waste of time.

Need to find the actual technical spec or a data logger to be sure.

AE82


4AGE



7700 MAX


On the track it feels like it should have more in it before it hits limiter and id like to pull another 500rpm if possible

yes stock tacho's can be well and truley out!!

mine was out by over 1000rpm from my silver top AE92 (with 101 dash cluster crammed in)

but as usual Sam is bang on the money.. it's the speed sensor.. thats why this AE92 had the 101 dash crammed in it.. electronic speedo

You should get about 8200 rpm out of it with the speed sensor connected. (Purple wire to ECU IIRC).

But unless you have done some tuning to the engine, my call is that the the revs you get will not net you any power. Take a look at my dyno run under the xAxx engine series in this website. Power don't go up.
You can see with the e-manage blue tune that those revs suddenly become useful.

Can't see any dyno chart in your dyno post ?

Must have unlinked itself. It is linked now. But still barely worthwhile. I guess you could say that it didn't lose as much power when upshifting...

So what do i have to do exactly?.. I have to run a purple wire from some place to some where do i ?..

Is that the standed dash that comes out in my car?..

Recomend i do anyhting with or change the computer?..



thanks guys

hey sorry for the delay I will give a proper answer when I have a moment
