Silentkillzr Posted April 8, 2013 Report Share Posted April 8, 2013 Ive noticed sometimes when cold, or almost random spots around town that when i leave from a light or etc. that it studders for a second or so and then goes, it just has that delay. Been this way for a while, not all the time just occasionally. Any advise would be useful. I do have a aldl cable for my laptop. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 8, 2013 Report Share Posted April 8, 2013 record datalog of it happening, preferably even multiple times in the log, post it somewhere and i'll take a look at it. just be sure to have some idea of when it happens in case there are events in the log where it doesn't.

Silentkillzr Posted April 14, 2013 Author Report Share Posted April 14, 2013 Alright i got two logs made up, went to the gas station and back, a few miles. Anyway it seems to happen more when its cold. Here's both files: http://specbar.net/wbody/triphomefromstation4142013.xdl http://specbar.net/wbody/triptogasstation4142013.xdl Im using the same adx files you gave me when i got the cable. Let me know what you think, seems i have a IC 24x Signal code but never have a SES light? Quote Link to comment Share on other sites More sharing options...
Garrett Powered Posted April 14, 2013 Report Share Posted April 14, 2013 I would like to see it but I don't have the ADX Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted April 14, 2013 Report Share Posted April 14, 2013 your TPS is acting somewhat oddly.... when you clearly have the throttle closed, resting voltage doesn't seem very consistent, it's why you're getting an elevated idle at times and why TPS% doesn't always fall to 0 or 0.39% when no throttle is applied. you may have a small vacuum leak as well.... with a 3x00, only 12 IAC steps with an idle speed in the 750 to 800 range is somewhat low. either that or the TB setscrew has been messed with. MAP at that idle is also a little "telling" of it. 24X DTC is present, as such, idle stability is affected a bit. Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted April 14, 2013 Author Report Share Posted April 14, 2013 Well it got a new tps before I owned it. I still have the old one to try also. Don't you have to calibrate it? Sent from my Galaxy Nexus using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 14, 2013 Report Share Posted April 14, 2013 calibration, no, on some older stuff(like 85-89 TPI V8 and early MPFI 60V6(fieros, etc)), it used to be necessary, but these PCMs allow learning of the minimum TPS voltage point, to an extent. go too far out of range and really odd things will happen. ideal is .5 volts with a fully closed throttle, but up to ~.7 or so(and down to ~.3 or so) will still be allowed to learn and not have issues. i replaced the TPS on the MC somewhat recently, base sensor voltage was always a good and consistent ~.51 volts, but lately when it got warm, sometimes when closing the throttle, voltage would dip noticably below that, so the PCM "learned" the new lowest voltage as 0% and when the throttle was actually closed, the PCM was calculating more like 3%. caused a REALLY high idle and some serious unintentional coasting issues. replaced TPS with a used one from an 03 impala(cause i'm a cheap-ass), base voltage is now around .6, so i reset the TPS learns(just disconnect the PCM fuse(s) for a minute or so) and now it's perfectly normal again. TPS is a VERY important input to the 93-95 3100 programs. Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted April 14, 2013 Author Report Share Posted April 14, 2013 I'll try returning to the old one and relearning. He only replaced it in the hunt to make it run. But it was the pcm in the end lol. Sent from my Galaxy Nexus using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted April 15, 2013 Author Report Share Posted April 15, 2013 Also another weird thing is I have no cat or rear o2 hooked up. PO hacked it off and made custom piping. I only have the o2 on the dp. But it seems to read rear o2? Sent from my Galaxy Nexus using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 15, 2013 Report Share Posted April 15, 2013 you don't have a rear O2.... or at least, you don't have a post-cat O2. the reason those show up is because of the 3.4 F-bodies. those used more or less an identical PCM(the manual trans models use the exact same PCM, automatic have provisions for the 4L60E) and those had an O2 sensor for each bank(left and right). for a FWD application, you only have the "rear" sensor, since the one sensor monitors both banks. you COULD hook up another sensor if you wanted to and have the PCM respond to it with a slight calibration tweak..... all something optional though.

Silentkillzr Posted April 15, 2013 Author Report Share Posted April 15, 2013 That makes sense. Pretty sure I do have a slight vac leak. When I got the car heater vents didn't work. They cut the vac lines when they changed the trans. I got it all hooked up but I don't have the right fitting for the intake plugin so I made my own. I'll revise that and mess with the tps and see what happens. Sent from my Galaxy Nexus using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Sent from my Galaxy Nexus using Tapatalk 2 yeah, I would like to check that shit out! I had a strange issue one time...but I have a 3400 swap of course, that wasn't my doing. but the throttle cable was loose when I hooked back up the TB after removing and cleaning one day. I had it installed correctly but it was loose now! turns out that a bunch of time got wasted tuning and tweaking stuff because didn't realize the cable tension was set when the TB end was installed INCORRECTLY. so I just went back to how he had it, left it installed incorrectly and went back to normal life, because the incorrect way was with the end nub turned 90 degrees in the seating on the tb pivot linkage. then that made the cable tight again which solved my problem. I know, ghetto because I didn't go back behind the pedal and adjust it or whatever, but its something to look out for anyway. see if the linkage works as should. mine took a minute to figure out because I had to try and picture how it was before, then remembered luckily. its a long story I know, just thought I would share.

Garrett Powered Posted April 15, 2013 Report Share Posted April 15, 2013 so I looked at the logs. bro you need the throttle follower tuned bad. I can see the voltage dips and read how your trip there and the trip home like a book. I saw the fan kick on and your alt not deliver the voltage you need.

Garrett Powered Posted April 15, 2013 Report Share Posted April 15, 2013 dude, everyone has that same problem. Let me see your BIN and I will fix it in 2 seconds. Quote Link to comment Share on other sites More sharing options...
Silentkillzr Posted April 15, 2013 Author Report Share Posted April 15, 2013 I found two vac leaks. The brake booster fitting was loose and I fixed the vac leak that powers the vents and such. I reset the ecm left the tps for now. I'll see if it keeps up on the voltage. Started up very well and catches idle finally lol. Haven't drove it yet I'll report in tomorrow.

Garrett Powered Posted April 16, 2013 Report Share Posted April 16, 2013 fixing the vacuum leaks is good and everything. It will help the MAP, especially if you were turbo. it will actually make your problem worse, until you tune it. when the idle dropped to 500 rpm as you took off, while the throttle plate opened up, that is the crappiest feeling. the car should start to pull forward slightly as you take your foot off the brake. you need like twice as many IAC steps. mind if I check out the BIN? I was just curious, wanted to see one for a 95 Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 17, 2013 Report Share Posted April 17, 2013 i could probably direct you to where i posted the XDF i made for the 93-95 3100 SFI stuff, i think some BINs are posted there as well? Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted April 17, 2013 Report Share Posted April 17, 2013 http://60degreev6.com/forum/showthread.php/48589-Tuning-available-for-93-95-L32-and-L82-PCMs?p=460539&viewfull=1#post460539 there's the XDF.... very unorganized, but i really don't have time to fix it, nor do i care to since i very rarely get to play with the MC anymore. i don't see BINs.... i'll probably upload them to that thread later.

Garrett Powered Posted April 17, 2013 Report Share Posted April 17, 2013 I would like to make available a drivability BIN for those cars with simply a throttle follower sweep that is more street friendly for people. I can't remember what is the process to making that year W-body able to be tuned? Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 17, 2013 Report Share Posted April 17, 2013 with a 93-95 60V6 SFI PCM, the only hardware needed is an ALDL cable. after that you need the software to upload and download the BIN to the PCM, that's done with the madtuner software. then tunerpro to edit the BINs.
