I went to the track again tonight after reinstalling my PB with Ver 2.0 tune.

I went late and got 2 runs, my father one.

Anyway it was 75 degrees on the way there but cooled off abit.
Best run of the night was a 16.616@ 83.95mph. The other run was a 16.800@ 83.53mph

The track was wet for my father's run. The guy mopped it down and then let him run then they delayed the runs to burn it off. A..holes!!!!! Anyway he ran a 17.295 (first time driving my car) @ 82.87mph. He burned all the way through 1st gear and had a terrible 60 of 2.598. I was hoping to give him one more chance to run but as usual someone broke down and delayed everything while they prepped the track.

Although I argued with him about holding the revs too high off the line, we agreed on one thing. The car dies when shifting from 1st to second. I am furious right now. I paid for shipping twice to have this thing (PB) retuned and although it works great with normal everyday driving, I wanted it for the track. That big hole in the tune does not make the car it's best in my opinion. Sure when you hit third you get pulled down the track but the 1st to second shift is killing my times.

I hope to get the fuel rail I ordered installed and maybe with a little more fuel present the shift will improve.

Here is the complete slip.

R/T------.665
60'------2.356
330-----6.949
1/8-----10.702
MPH----65.43
1000---13.930
1/4-----16.616
MPH----83.95

Sorry for the long rant but I wanted my dad to get another shot at the track and was hoping to get everything on film since he is here only for the week but the delays screwed that up. I was also looking forward to break some of my old times.

I took off the injen CAI and put on an RMR intake. At least my 60's were good this time.

Thanks for reading, I'm going to dig up my old times.

Peace

On another note a performance shop had a turbo CIVIC that ran a 10.7XX with slicks. I think it was the fastest car there on the night. If not it was damn close.

Actually not a bad time for an OZ, you'd probably give my Audi a run for it's money until it's chipped. Man I wish I had an EVO, but the Audi isn't so bad, better than a Sentra GXE

 

I know it's not a bad time for an OZ but I think it could be better. When a car bogs for even a split second that is a waste of time on the 1/4.

It's baffling. On my way home from work just now the car want's to go go go, but if you leave a light quick and shift to 2nd at high revs there is a dead spot. That's the only place where it is noticeable.

I guess I'll just have to live with it.

sorry bout the other thread. didn't know you were bumping it for reference.

as for the bog in 2nd, you're not gonna get around this. the stupid way our cars are geared, you're gonna land under the powerband in 2nd even if you shift at 6250 in 1st. technically, if you shift at 6250 in 1st, you land at 3396, about 600 rpm before the powerband. unless you get a longer 1st gear(don't we all wish), or get a good low torque cam, you're not gonna be able to fix this problem.

 

Thanks Rhyzin. It's great to hear the technical side of my (our) problem.

besides clutch slippage/wear or motor mount wear, i can only really attribute the loss in torque to intake design if that is the only changing factor. a CAI will have the characteristics of having better torque at the cost of a lazy top end and slower throttle response. a SRI will have better top-end and better throttle response at the cost of torque. try throwing on your CAI back on and see if you can break them tires loose.

before you try to break them loose, drive around for maybe 30 miles or so so your ecu will change the Long Term Fuel Trim to the characteristics of the CAI.

EDIT: what is the actual mod combo you had when you were able to break tires free, and what is it now?

 

The only difference is the PB.

I've had the CAI and SR without the PB and in both instances the car has power during the 1-2 shift. Granted it is not as fast without the pb, but there is no presence of delay from the shift without the PB. I wish I could describe it better but it really feels like the engine jerks and the car dies. Having someone else drive the car and say the same thing proves to me that I am not just paranoid.

I sold the CAI so there is no going back in that direction, plus I wanted the top end side of things since our cars are supposed to have plenty of torque but we all know the top end is lacking.

oh snap, forgot you had the RPW header. just a hunch, but if the header demands more fuel at lower rpm, then the PB may be making the ecu run too lean. if the rpw does produce better exhaust scavenging due to it's design(a difference i'm sure you know designates it from the rest), fuel requirements at low rpm may be greater, opposite of what the PB does. if the rpw header does produce the hp both you and i believe it does, then the actual change in fuel maps may be great enough to need a map different than the RRM one provides. this is all just a thought and may not be the case (my little disclaimer hehe).

 

Thanks for trying to help me out.

What you are saying makes sense. I may just take it to a shop and have it dyno'd with and without the PB. That will be the only way I know for sure. When I have $150 bucks to waste I'll go that route.

I won't be satisfied until that 2nd gear pull is back. I want my cake and will eat it too.

i here you on the bogging from the 1 to 2 shift..i got got the PB,rrm header, injen intake, and catback and the car does the saem thing your talking about...interesting...ima gonna try to dyno or run also

 

i acutally tried this today but 1 dropped me off at 3700...no power shifting jusy shifted fast....??

 

i got 3396 mathematically. shifting while giving it some gas is like slipping the clutch on a launch. though you're not technically powershifting, you're bringing up the revs before full clutch disengagement. also, needles are pretty lazy. if you had a digital readout, you'll probably see a lot lower rpm between shifts. either way, quick shifting will yield higher rpms in the next gear if you're not losing time from clutch slippage. we just have to figure out how to bring the powerband lower. or find a taller first gear replacement from another car.

 

IC....so whos gonna make a taller 1st gear?

 

quaife made one for the RMR rally lancer that helped them cut down their times out in the dirt. i never personally contacted them since i assume i wouldn't be able to either a) afford it, or b) put it in myself(yet). it might also not be as easy as it sounds. you might need a new gear cluster as well as 1st/3rd gear replacement. i dunno since transmissions aren't my forté.
