thanks!

 

Thanks for all the help guys. Will be leaving work in a few mins and then preparing to get down and dirty.

 

I guess there's a descrepancy in the manual. I found where it states 16ft. lbs (page 11A-30) in the manual, but also shows 98ft. lbs. (page 11B-29).

 

well just got done...Worked fine. Now if i can get the car to learn the cams, it will be all good. Took a while though to get everything going smoothly. Took a while to get the caps off and also get the gears back on. Found out I didnt even use the tensioner until putting the gears back on. LOL i thought i tightened the tool down and it didnt tighten down at all. But I did have to make sure I used it when putting the gears back on. the homemade tool worked fine.

 

Road test it yet?

 

hows the idle?

 

well since im on stock cam gears and reset the ECU it seems to be really lopey at idle, and also has a very sparatic idle with it adjusting itself up and down when sitting still. Vacuum is around 12psi. I am hoping that within a couple days the ECU will learn to adapt to its new friends a little better at idle. The loping doesnt bother me at all though. I havnet really put them to the test yet, but overall seems to pull alittle better mid-high rpm range. Cant wait to get them tuned out in the future.

 

how safe is it to run with the car untuned with those 272s. i am going to install those along with the cam gears soon. i am dynoflashed for turboback,hks intake, walbro pump and mbc.

 

i dont know if there is any safety issue at all except maybe the car feeling like it could stall out at idle. Other than that, driveability seems to be fine.

 

any ideas on sparatic idle...not lopieness, just the idle bouncing up and down up and down and the car running really lean and then adjusting itself to really rich and back and forth resulting in the sparatic idle?? Any conditions that would be causing that?? I have a very repeated loping sound for a few mins and then the idle raises up and back down...rich/lean. And then it goes back to a steady lope for a few mins and then repeats the up down idle thing over and so on. Any thoughts?>?

When I hooked up a widenband and checked my AFRs after intalling my Piper cams, I found out a couple of things. The AFR at idle managed to stay loosely around stich, but the cams had a pretty solid lope at 0/0 with the cam gears. There was some hunting, too, while the ECU tried to adjust the AFR. On my car, I think the cone intake is one of the causes. One change that helped quite a bit was decreasing the overlap with the cam gears.

When crusing and off boost, the ECU was able to keep the car running at stich without problems. On boost, though, I needed changes to the stock A/F map. I have an XEDE, so that covered my needs.

 

how do you like the XEDE?? ive been looking into different managment options lately

 

You will likely have to deal with the lopey idle until/unless you get the cam gears and dial out some of the overlap and/or possibly revise the idle A/F mixture using a suitable device.

I am also more or less sold on the XEDE as a tidy, single comprehensive management option as opposed to fiddling with two or more devices by two or more different manufacturers. As always however, any such device is only as good as the individual doing the tuning. Fortunately, the available Vishnu maps look like good places to start.

 

I just installed my 272's and head studs on Saturday. The car sounds different at first seemed as if was going to bog out, but it did not. My idle is kind of lopey, but that is because the cams are so aggresive. With my Xede, I just loaded up a new map and was ready to rock. I have run the car with the A/C on and without and have not experienced any idling issues so far. The best part is the power, WOW, the car really feels like a new animal.
