Zfan1 Posted September 18, 2013 Author Share Posted September 18, 2013 Well, transmission will not shift, goes into first, nuetral, reverse and park only. Maybe a tcm issue. I am going to pull the main plug socket and make sure there is no trash in the recepticle/socket on the trans side otherwise I will have to pull the transmission....yuck!

Zfan1 Posted September 28, 2013 Author Share Posted September 28, 2013 She is ready for her tune on Sunday and then on the road she will be. If all goes well I will take her to the local track next weekend for some base numbers. Quote Link to comment Share on other sites More sharing options...

Zfan1 Posted September 30, 2013 Author Share Posted September 30, 2013 ECM took a dump, what luck, car left me stranded on the street tuning segment. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted September 30, 2013 Share Posted September 30, 2013 Just to cheer you up, I ran out of gas during an autocross. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted September 30, 2013 Author Share Posted September 30, 2013 LOL, kind of funny how some things happen. Did you have to push it far? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted September 30, 2013 Share Posted September 30, 2013 I keep the fuel level low because in the heat of the day it sometimes expands and pukes out the vent line. For some reason I was so sure I had 1/2 tank that I didn't check the gauge even when I loaded car. We pulled up to the grid and I said to my co-driver "we are pretty low on fuel, we'll get gas at the lunch break." I have a good baffle in the tank, and I have drag raced with a super low tank (stock motor-I'm fast because I'm light), so I thought I might get away with it. First sweeper, power cuts out, but car kept running. Once I got out of the sweeper I was able to nurse it to a gas station. 7 gallons later we were hauling ass again. My brakes so totally suck. AZC kit arrived this week. Itching to get to work on it. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted October 1, 2013 Author Share Posted October 1, 2013 John at PSI (Wiring harness maker) says it is not the ECM but adjustments in the ecm/tune that need to be made. He asked for the file/tune be emailed to him for adjustments. Fingers are crossed, hope it works. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted October 9, 2013 Author Share Posted October 9, 2013 Replaced bad ecm and got a base tune in her, she goes to the dyno today for her final exam...LOL I took her to the track on a base tune and went 6.91 at 99 just rolling out not stalling her up just off idle. Was kind of dissapointed but she may have a lot left on the table that we will find on the dyno. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted October 12, 2013 Author Share Posted October 12, 2013 (edited) Well that 4L80E is a power robbing SOB!!! Put down a best of 418 to the rear wheels, had some strange vibration issues on the dyno, got to rebalance the drive shaft before it tears something up, not to mention losing power too. Going to have to send the converter back too, it was supposed to flash to 36-3800, only flashes to 3100, that will not work at all.

RebekahsZ Posted October 12, 2013 Share Posted October 12, 2013 You still went sub-7 without really trying. That's fast in my book. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted October 12, 2013 Author Share Posted October 12, 2013 My tuner said that in a 600rwhp car (Corvette) with a 4L60E transmission that broke twice, they swapped in a 4L80E and it only put down 540rwhp. A 60 rwhp loss swapping from a 4L60E to a 4L80E, I about crapped, that is a rediculous power loss. Makes me want to swap in a 4L60E but the idea of breaking the trans has me on the fence. I am going to take it to the track and see if it picks up anything before taking it apart again. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted October 12, 2013 Share Posted October 12, 2013 If you bracket race, it doesn't really matter how fast car is, just consistent. Plus, it sucks to go super fast and always have a broken car. Fun comes from RELIABILITY. Get that cooling fixed and get racing! Chin up.

Zfan1 Posted October 25, 2013 Author Share Posted October 25, 2013 IMG_0371.MOVFinally made it to the dyno, made 418rwhp and 397tq thru a power robbing 4L80E. Tuner said the 4L80E eats 30-40 more rwhp than a 4L60E....crap! He said that thru a 6 speed It would be in the neighborhood of 475-490rwhp, makes me want to put a manual in it. Sorry for the crappy phone video my friend made, forgot my good one. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted October 25, 2013 Share Posted October 25, 2013 That hp rating doesn't match the sub-7 1/8-mile you are running! Supposedly, I have 435 tq and you are flat running off from me. I think you are kicking butt. What is your drive time to Little Rock, Arkansas? I'm about 6 hours. Perhaps next summer we could meet at Centerville Dragway an hour outside Little Rock for a Hybrid Z race night with wfritts911 in his LS1-powered car. Its a great 1000 ft. track-super clean, smooth track with a really nice family atmosphere and a great vibe. Quote Link to comment Share on other sites More sharing options...
Zfan1 Posted October 26, 2013 Author Share Posted October 26, 2013 Went to Ennis this evening, too many street tires made for a slick evening. Only made 2 passes before a huge drop in tire pressure made me aware of a leak in the drivers side rear drag radial. I picked up a nail/screw at the track of all places....damnit! First pass I spun to a 1.67 60 ft. but still managed a 10.91 at 125.45, last pass was even worse, spin fest, 1.77 60 ft. ran 11.03 at 125. I drove the "Purple Turd" 70 miles each way, no trailer queen here...LOL Quote Link to comment Share on other sites More sharing options...
