hmm you should be running a P72 if you got a GSR motor

riceburnerryan

sounds like you are running a P28 without a chip... and then a P30, so get a P72 or a chipped P28 with a GSR map on it..

JaydmEg

hmmm but why would the b17 ecu work? or my obd1 p30? u think i need a p72 cuz of all the gsr intake mani bullshit?

waterfordtuners

dood u def need a p72 or a chipped p28. i have a 94 coupe with a 97 gsr and im running the p28 and my vtec isnt kicking hard and it redlines at 7200 but when i throw on the p72 it [freak]in rips

JaydmEg

when i put my friends p61 b17 ecu vtec popped hard as ****! when i put the jdm b16 p30 vtec popped [freak]ing hard also just doesnt go to 8200

jeffnerette

i have the exact same set up but i am running a virgin p72 and my car does the same thing. i would also like to find out why.

iamthefollower

I had the same problem, i swapped the stock tach and such in my car and it fixed it..

JaydmEg

idk why the tach wouldnt let it go to 8200... myt vtec is popping i bthink the tach is ok im gonna try my friends p72 and see how it works. i also have a gsr cluster that i can put in my car so we"ll see anymore thoughts???

iamthefollower

it wasn't the tach it was the wiring had fried it.. i swapped my tach.. well i swapped the whole cluster actually, and it ran perfect after that.. just trying to let u know from personal expierence on mine..

That.

Or maybe the motor isn't a Gsr.

GSR motors have the secondary butterfly valve you can unplug it and it should run fine with those ECUs or get a regular intake mani

vtec pops? omg how do you make it pop harder? maybe by upgrading the vtec solenoid to a type r solenoid? omg and adding new vtec fluid!

What's your oil pressure like? VTEC wont work if your oil pressure is off....do you check your fluids often?

jeffnerette

VTEC works. the problem is that i redline at 65k rpms

Shocka1998LX

ok I just want to make sure.. as long as you know VTEC is working and its not just the secondaries that you're hearing when you think VTEC is popping.

I just know that I had an issue once where VTEC stopped working and my redline dropped to about 6500-7000

jeffnerette

it not the secondaries because i got a skunk 2 manifold. im sure its VTEC.

IACV or TPS or Dizzy one of those 3 i had something happen like this, and it was my TPS

raidacaipo

are you getting any check lights? did you check your oil pressure signal on your cluster? double check your oil pressure switch on the back of your block. also double check your wiring harness. something might be loose. this happen to me a while back and I find out the oil pressure switch was loose and wasnt plugged in..

where exactly on the back of the block is oil pressure switch on the back of the block. left right top or bottom. sorry im new to this.

iamthefollower

it'll be in the middle next to the knock sensor.. it's one wire running to it..
