Bigfoot Posted January 9, 2007 Share Posted January 9, 2007 I did a little experimenting tonight, to see how things are going with my new mods. Nice and cool outside. Just tried a few "launches" to estimate 0-60 time.When I drop the hammer it just really takes her a long time to get going. It's like she's bogging down real bad until it climbs over 3000-3500 RPM's, then she really goes. I even get a little bark shifting into second gear (auto, and just a little one). Yes, TCS is off. Just like on club day at SpeedworldI checked the DIC for codes and did get a P0137 and P0157, both rear HO2S sensor low voltage codes (from the way I read it meaning lean condition). But I did not get these every time.Anyone have any ideas other than spending a fortune to have it checked by the pros? Link to comment Share on other sites More sharing options...

Bigfoot Posted January 9, 2007 Author Share Posted January 9, 2007 Thanks Mike, appreciate that. Today might be tough for me though. I might be able to swing by on Wednesday if you are there the same hours, Thursday should be better. If I can make it either of these days I probably could not make it until 5:30 at the earliest.Let me know if the hours for you are the same all week and I'll definitely try and swing in one of these days, and I'll call when I'm rolling.Sean Link to comment Share on other sites More sharing options...

Bigfoot Posted January 10, 2007 Author Share Posted January 10, 2007 OK, here's what I did on a hunch (thanks to Tim "P51tj").I borrowed a throttle body to slave in, in place of mine (AF terminology). Last night my 0-60 times were approximately 9.5 seconds. Tonight, with Tim's old throttle body from his "yeller" car , my 0-60 times were about 6.3 +/- .2 (all timed by hand, by me while driving the car). That's an improvement of about 3.2 seconds!!!!!! MAYBE YELLER IS THE FASTEST COLOR!Both outings I made the pulls about 4 or 5 times. I'm thinking I've hit upon something here. I'm gonna leave it there for a couple days (with Tim's permission of course) and see how things go.I still plan to take her to AZP&S and have Mike run the quick check for me.Anyone have a guess what this might translate into on the 1/4 mile?

sloryde Posted January 10, 2007 Share Posted January 10, 2007 Is this throttle body bigger than yours? If its the same size then is yours just not opening all the way? I dont get it, elaborate...Joe Link to comment Share on other sites More sharing options...
Bigfoot Posted January 10, 2007 Author Share Posted January 10, 2007 It's the stock 78mm from Tim's '03 I put on my '99. I had a hunch that mine was acting really slow opening up during a "launch" and asked Tim if I could borrow his. I could tell the difference immediately. I think the servo mechanism in my old one may be going bad.I know 6.3 0-60 is still not great, but it sure as hell is better than somewhere over 9.I'm still going to have Mike at AZP&S take a quick look...but at least I think I'm on the right track.

Guest UVETTYA Posted January 11, 2007 Share Posted January 11, 2007 Don't have an extra FAST 90/90 laying around that I could snag, do you? J/K!That's a generous offer Mike. Top notch. Steve Link to comment Share on other sites More sharing options...

Bigfoot Posted January 11, 2007 Author Share Posted January 11, 2007 Yes, very cool. I will also try and swing by today some time after 5:00...but before 7:00 of course. Link to comment Share on other sites More sharing options...
Bigfoot Posted January 12, 2007 Author Share Posted January 12, 2007 Well, saw Mike at AZP&S tonight....His puter tells him I need a tune in a baaaad way. He's gonna do one tomorrow just to make the car "safe" as he put it. Apparently I'm running really lean and and my timing is way out of wack...that's not good on either front.He said no WOT until he does that for me. Hopefully things get better soon. I will need to get with Nick some time to do a full tune though. Link to comment Share on other sites More sharing options...
Guest UVETTYA Posted January 12, 2007 Share Posted January 12, 2007 That's good news. Someone who doesn't know what they're doing might have gotten in there with a Predator or something. Lots of possibilities. Good luck!Steve Link to comment Share on other sites More sharing options...

Desertdawg Posted January 12, 2007 Share Posted January 12, 2007 Get it tuned and I will have to change your tag... (just call me SLOW C5) Link to comment Share on other sites More sharing options...
Guest AZ Power & Sound Posted January 12, 2007 Share Posted January 12, 2007 Most C5s ping a bit and are a little lean from the factory... thats normal and just part of building a car around sea level and 93 octane... neither of which we have, but when the car has massive detonation and extremely lean its usually either a dirty / bad MAF sensor, or someone stuck a nasty tune in there at one point! Hypertechs, Predators etc basically just lean out the car and add a few degrees of timing, which makes an already dangerous tune severely bad!

Bigfoot Posted January 17, 2007 Author Share Posted January 17, 2007 Mike took care of me tonight...as best he could. Apparently my MAF is bad and not letting the car go to WOT fully. The car is safe to drive, but needs a new MAF. I checked mine out and nothing out of the ordinary...screen is clear (dusty but that's it), the filaments are fine, so it must be electrical.Anyone have a spare one laying around that you are not using/going to use?
