hey ive watched this video about a billion times lol i think i have my car tuned in pretty good now but i had a question it seems like when going up hill my car kinda has a miss to it, it feels like its chugging going up hill lol my neighbor says its the vac lines and i was wondering if theres a way to eliminate all the lines on the tb? do i just pull them off and plug the nipples on the tb? and i know some go to egr do i need a egr block off plate? thanks for the help!
how do you know its supposed to be .63? j/w and this can be done with just a multi meter right? im getting ecmlink eventually but im just looking for a cheap laptop first
You have to use a test connector (or pierce the signal wires with a voltmeter), and test it while it's connected. I would have showed that except I don't have the Mitsu test connector for it, and didn't want to damage my harness.
With a .45mm feeler gauge between the SAS & throttle lever, you have to connect a voltmeter between pins 2 & 4 and the standard value is 400-1000mv with the throttle plate closed. The idle switch is pins 3 & 4.
@Jafromobile~ dude you're an absolute noob at this!
U could have just got someone to hold the gas pedal down and then you go see if u can open the throttle any further with your hand!!.... u dont have to rely on TPS value to test this!!
@marek0086 You can open a 1g throttle body more than 100%. If you can't look into the throttle body without disassembling half your intake, how do you know you're not opening it past the point where you should? Go back to 8:55. I explain this.
This method a) sets the CLOSED value of the TPS b) ensures you hit closed loop idle c) does the exact same thing, d) doesn't require a second person, e) verifies the throttle plate is open all the way. If it does the same thing, how am I a noob?
@marek0086 No. That was a spinal tap quote. A joke.
The throttle plate is on a free-floating axis. There are no stoppers for open and close positions. I had swapped the sensors from a 2g, so they needed to be set. If all I had to do was remove slack from the throttle cable, your method would have worked.
@marek0086 There is an external closed stopper (the switch) that's adjustable, but it has to be set just at the point of preventing it from sticking closed. In DSMlink, that value is .63, but it recognizes a range of values for closed-throttle. That's the sweet spot. With a volt meter, the values in the video are straight out of the service manual for a 2g.
@marek0086 If the throttle body you're using has a static open and close point, yes, your method is the fastest way to remove slack in the linkage. My 2g throttle body would have been a better one to use for your example.
This is a 1g throttle body using 2g sensors. It needed adjustment because it was just installed and the 2g sensors were swapped over. It needed a lot more attention than just accelerator cable slack.
@DALE97DSM It's a Blackhawk 3/8" ratchet. Everyone loves that thing, but It's mostly a novelty. I confess to having used it within the past 45 minutes, though.
all i know is its a learning process no matter if youve been at it for years or just taking baby steps, so all im saying here is thanks for this useful vid. im some what familiar but i love learning watching any and every video compare and contrast trial and error staying up all night just so you can get it right, thats what its about. thanks for the quality video man.
lol not all cars are like a DSMs and have such a long range of fuel correction Tunning is a must for people doing major mods to there car. Yes being mechanically sound is an absolute must but 95% lol that might be a little exaggeration the actual air fuel ratios and ignition timing are where most of your power and efficiency will come from. that is per about of air allowed into your engine at any given time. without that your car has to work even harder for the power.
@NoSleepRacing NONE of your fuel or timing settings matter if your throttle plate doesn't open all the way. Your tune would already be wrong.
That's why this video is tuning 101. It's intended for anyone attempting to make sure you start with systems operating at peak capacity so that what you do with fuel and timing matters. If someone starts tweaking their fuel and timing settings without doing a boost leak test and verifying these things first, I won't waste my time giving them advice.
@Jafromobile I do know that I tune myself I just thought the 95% comment was funny. I have been watching your videos and do like them. Do you do any of your own EFI tuning with a dyno?
@NoSleepRacing I had my car baseline tuned by Thomas Dorris. We got 80 more hp out of it at redline on a Dynojet. Later, I added a 3.5 bar MAP sensor to calibrate airflow metering of the GM MAF and managed over the years to eek another 33hp out of it track-tuning the airfow tables, and now it's at 12.2:1 AFR on pump gas with zero knock. Someday soon I'll get a wideband to make tuning more like cheating, and I won't really need a dyno anymore once that happens. I live a mile from a dragstrip.
@Jafromobile well you can always get better results on a dyno. Controlling your flame front to get a complete burn to happen and the exact deg of rotation for maximum deflection loss is only possible by seeing TQ output from a dyno. You can get pretty close with track tuning but can never get quite as close as you can on a dyno. If you ever need any help with any of that feel free to send me a message.
@NoSleepRacing I'm making 475 crank horsepower & 357 awhp and 12.20's at 116mph with 550 injectors if that helps answer your question. :) Changing the injectors this weekend to RC 750's, it's a welcomed occasion because fuel has been a limiting factor lately. ECMlink v3 is on its way, and I'm converting to speed density.
@Jafromobile peak HP is not everything and you can also get much better times by change timing is other load ranges "swept area" to make sure you have perfect TQ when shifting as well loads of things to consider those are pretty good times but I am still willing to bet you can improve it a little. Speed density is a great idea but once you do that remember you are losing your air counter so you are really going to have to make sure you tables are really great cause you will not have as much play
@NoSleepRacing I think you're misjudging my experience. I have been tuning on this particular car since you were 17, and several others before it. I've put it through more than 180 drag passes, 5 dyno sessions 4 transmissions and 2 rebuilds, 4 turbos, 8 trophies and a 2nd place finish in a bracket money race. It's just a standard Big16g, and there's nothing left of its potential with 121% injector duty cycle. I'll send you a PM, this is very off-topic for this video.
@Ballplaya549 It's a Blackhawk ratchet and I think I bought it from an Advance Auto Parts rep. They're not hard to find. Lotsa people have WTF'd about it, but unless you already have 14 ratchets like I do you probably don't need one. Check out the other comments a page back.
@jkonn7 Rarely, but I'm grateful for them. I need to contribute. There's nothing that I can add that the brilliant people there haven't already. 'cept maybe the video part...
@Jafromobile Man dsmtuners is all either complete dumbasses (Me) or extremely intelligent people who don't care to waste their time with the dumbasses. We need more people like you that are willing to do things such as you did in this video, teach the dumbasses in a easy and understanding way. By the way i appreciate these videos man, theyre awesome. You should talk to a moderator about adding all your videos to the beginners faq thread.
You also have to put into fact of setting the computer to where you live and the temperature... and all that sorts of stuff if you want the max power but thats for like pro dragsters... not needed but if you want hp and torque thats one thing you want
Some great key points in this video. Good job man. I look forward to your next one. I hope you demonstrate Link usage in the following vids, as I requested a loooong time ago. lol
@7inchexhaust I just haven't taken the plunge yet. I'm having so much fun with this thing right now, I don't even want to take it off the road for the weekend. Will probably do it this fall. The v2 app has a TPS offset as well. I like to get the actual sensor in spec rather than making the ECU compensate just so nothing is ever in question.
@Jafromobile Cool man. I actually fully understand. But I meant use the v3 app, not actually upgrading the ecu's chip to v3. I have v2 and use the v3 app myself. Although I do recommend the upgrade to v3. Only reason I don't have it yet is because I'm poor lol.
@7inchexhaust Oh, right on. Yeah, I have a new Mac that I intend to use for v3. The one I have right now... I had to hack all kinds of stuff because back in '06 when I linked, there was no Mac version and it had to be recompiled for Java on Mac OS X with a Sun Microsystems serial driver, and a very specific serial adapter to make it happen. I guess I just didn't want to end up with a brick since this setup works beautifully. I'm doing both shortly.
@Somnambulist513 HAHAHAHA! Yeah. Uhm. I knew someone would comment on that. It's a BlackHawk ratchet. They're around $30. It ratchets both ways leaving you with the equivalent torque of a screwdriver. You know... this is pretty much the ONLY place I use it. It is by far the best tool for adjusting a TPS sensor, but proves itself to be underkill on just about everything else. Until I found how good it works on a TPS, I sorta treated it as a novelty. I wouldn't steer you wrong.
badass ratchet, period!!!!!!
