GSR newbe

hi, i just traded my coupe for a GSR, so i got a few questions. first, where can i find the fuse maping. i mean the paper thing under the stering whell thet lets u know for what is each fuse for, (its a 99 two door GSR). and also the RPM gage doesnt work so if any 1 knows where to start cheking for a lose wire or something, and also at what rpm Vtec kicks in? so thats it for now. thanx for ur time guys hope to post again soon.

around 5800 for vtec from what I heard

I always thought vtec engaged in two stages with our engines. One stage at 4400 rpm, the third lobes engaged, and then at 5800rpm or so some extra intake valves open up (most people see this as vtec engaging)

go pick up a helms for $60. best $60 you will ever spend.

whats a helm?? and also wich wire on the ECU is the one for the exaust sensor?, so i can conect the mixture gauge, and wich is the vtec wire?

you have it backwards. 4400 is where the dual runner intake manifold opens up more to allow a little extra air in. 5800 is where the vtec kicks in.

Ok gotcha. But it is two stage!


To answer your question, a helm is a manual for the car. It is like a a Haynes repair manual. Helms manuals are good.

i thought at 4400 rpm is where the "secondary butterfly valve" or somthing like that opens up, then at like 5800 is where vtec really kicks in. just what i have read some where.

ummm just skip back two posts man...

thats all great to know thanx guys but i erally need some help if any1 can direct me to a ECU diagram will be great. and also i still dont know whats a helms and what is it for?. im gona check e bay. thanx again

I said previously, when he said "Helms" He was refering to a "Helms Manual." It's a repair guide for the car.

a bible for any honda/acura home mechanic.

one that would have diagrams that youre asking us for...

even a 14 dollar haynes manual would have the diagrams if you don't feel like splurging for the helms.

i think you guys are wrong about the vtec, it engages at 4400, i tested mine and at that rpm is when it kicks in.

This thread is a month old...

i think you are wrong. go back and reread the posts in this thread and you will learn what is engaging at 4400.

the only way that it could engage at 4400 is if someone reprpgrammed it to do so for some reason.

well i conected a ligth to the vtec sensor and it comes on at around 4400 RPM if it is a second buterfly why is the sensor engaging?? , you can check just by conecting a wire to the sensor with a ligth bulb and ground it to where whever u want and check it for yourself

On a Gsr, the pins engage through the rocker arms at 4400 rpm, which creates high valve lift from the center lobe on the cam making contact with the center rocker arm. This is what is meant by VTEC, it kicks in at 4400rpm. The intake manifold changes profile at 5700rpm, from long runners to short.

In a Type R the whole VTEC lobe thing happens at a higher 5700 Rpm, since the primary cam lobes are bigger than that of a Gsr. There is no Variable Intake manifold on a type R.

That's exactly what I thought.
