hi guys, i just recently picked up a 1994 integra gsr with 153xxx on the clock. the car is Practically stock, just 3 inch intake with k&n filter, dcsports 4to1 header, cat delete and 2.25 exhuast system.

I have driven a few gsr's in the past and really didnt feel like this one. heres the problem, when i'm getting on it i dont think i'm hearing the butterfly open up, also when i shift from 1 to 2 at 8000 rpm, the car seems to bog down for second before it pulls again. Then sometimes shifting from 2 to 3, the car feels like that too.

Correct me if i'm wrong, the gsr's i've drove in the past, vtec normally hits at like 4500-4800 rpm, then the butterfly opens at about 5600-5800 rpm. And when the butterflys open up, it sounds just like vtec too. But my 94 gsr, you can hear vtec but not the butterflys.

My question is are some gsr's like this, where you cant hear the second butterflies open up, or is there something wrong with my intake manifold butterfly's? Any way to test it?

I'm thinking the reason my car bogs down a little when shifting from 1-2 and 2-3 is the butterflies not opening, anyone else have had this same problem?

 

has the ecu been remapped?

 

those are fairly high rpms to bog down on, check spark plug gaps? change fuel filter? there's a lot of little things that can make this happen. start with the basics.

 

If im right the only thing youll here is those butterflys open up at 5600rpm may be 5800 i know the GSR differs from the 92 GSR's and the SI b16.
as far as the bog i know my 92 original gsr would bog down and then would just kick and run great... I replaced the main fuel relay and problem solved.
I would start with the basics like previously stated.. plugs, filter etc.

good luck

 

not trying to argue, but i dont think tbe Si b16a2 has secondary butterflies.

 

no prob, you could be right

 

plugs, wires, cap and wire has been replaced by me, car had a speed innovation chipped and tuned ecu on there, didnt like it so i had my tuner burn me a stock gsr chip ,and threw it in. Had him look everything over to make sure everything was right and it was right.

I'm kinda lost about the car. It feels wierd, its not a actual bog down, but you can actually feel the car pause for a little bit after shifting then slowly picking up again. rpm falls to about 5800rpm-6000 rpm depending on how i shift.

 

Would you say its hesitant... lets say your on the gas rpms stay relitivly the same no matter the throttle position, or slowly increase like its bein held back an then it gets full power an takes off

 

yea, i say its like hesistant. I have a slightly modded si and have driven many kseries, bseries and swaped cars. This is the first time i've notice a gsr doing this.

Normally, you powershift from first to second, the wheels spin a little and the car pulls instantly once the wheels grab again, shift to the third, feels the same way. Well my gsr, if you ever driven a b16, its like falling out of vtec in a b16, then coming back up to hit vtec when shifting 1 to 2 and 2 to 3. But my gsr is staying in vtec, but you can feel that lag for a split second, its not long.

For example, i ran a b16 delsol last night, off the launch, i pulled maybe half a car, shift to second gear, my car kinda hesitated like that, during the hesitation, the delsol started inching on me, car finally starts to pull again and i stop his pull, then shift to third, same thing, car hesitates, he starts pulling on me again, and now were neck to neck and then when car starts going again, i start slowly pulling away, ending up about a fender and slowly pulling by the time we hit fourth. The car chirps from the shift to 2 and the shift to 3, so its not my driving.

I'm sure if the car didnt hesitate like that, my car would just start pulling as soon as i get in second but because it hesitates its slowing my car down. At first i thought it was just my mind playing tricks with me, but when i was running the delsol, i could really just feel the car pause/hesitate for a second.

 

up, still need help.

 

check oil level computer wont let motor have all power if numbers dont match up first not enough oil pressure u wont have any power whan its suppost to kick in

 

i saw a vid of a gsr bogging at high rpms like that..it was because of his coil in his dizzzy. and i can hear everything clearly from 4,500

 

get a stock ECU and get rid of ur stupid chips and all that BS

 

Yea I was going to say try a stock unmolested ECU before anything else to rule that out (or confirm that) as the problem.

 

just boost it and get more power.. good luck with the problem

 

Alright, some more info after looking at the ecu. Its not a p72, its actually a p06 or p28 chipped.

Now my question is, i was told that neither of those ecu's can operate the butterfly's unless you convert the ecu. I was also told that if you are running a non gsr ecu on a gsr or if the butterfly's arent wired up, the butterfly's stay open the whole time. Can anyone confirm this? Need help.

 

you need the stock ecu p72
