    ECMlink Help with tuning SD. What next?

    I just noticed that the ? help on the RPM/TPS page says that timing at idle is varied to help control idle speed. Not just the ISC. So maybe this is where the unexpected timing numbers are coming from, and why they don't match the chart we can see. I think it would be interesting if there was...

    ECMlink Help with tuning SD. What next?

    The 17-02 log looks pretty decent. I've been looking at the part after the throttle blip where the rpm gets down into the 700's at 8.4 seconds. At the same place the wideband gets maxed out full lean (even more than maxed out - it hits 4.14 raw volts LOL) Maybe you could say that it's all weak...

    Basically, your ecu cuts the fuel to 0 (InjOn) whenever you take your foot off the gas (IdleSw=1) and your rpm is greater than your target idle + FCoffset. (There is actually a delay of about 0.7 seconds to do this cut). Then as your rpm drops (foot still off the gas), the fuel is supposed to...

    You might have a vacuum leak or you might have a bad ISC. I don't think you've replaced yours have you? The ISC has a test or 2 but it's almost a waste of time because a bad ISC tests good usually from what I've seen. Anyway, in this last log, the 15-18 log, it looks pretty likely that the ISC...

    Yes, I think if you have it adjusted so that the closed loop trims are a little negative ("pulling") in this region just before and as you go into open loop, then, as soon as it goes into open loop it should immediately switch from trying to be stoic to running whatever your table says which...

    Street Build ITFLYS - 1Gina2G

    In the install pdf they have a paragraph about the return orifice. It says "The DMR-RA is equipped with a removable flow orifice. Radium Engineering has optimized the size, shape, and material of this orifice for all single and multi-pump applications. The orifice will NOT need to be changed...

    Do you know what model of fuel pump is in there? If we knew what pump it was, we could use the flow chart for it to estimate when it will be going over the edge.

    You might someday want to make a heat shield for the alternator. Here's my alternator heat shield thread. It was kind of a high effort way of doing it, but it is still on the car and so is the same alternator I had then...

    Yeah that picture #7 that Steve showed. My AEM wideband and the other 2 AEM gauges ground to a 6mm bolt on the same piece of sheet metal, and it seems to work fine. It's at the orange arrow in this pic:As for your wideband sensor location, 4 to 5 inches after the turbo is closer than the...

    Ahh, this is something I was thinking about asking you - if the Autometer gauge agrees with the LinWideBand numbers you see in ECMlink. Sounds like you are saying that they were not agreeing when you had the Graph Item Preferences set the way they are "supposed" to be (4 volts = 1.16 lambda =...

    So I just looked at the user manual for the Zeitronics ZT-3 Wideband and man they do a good job of explaining this thing I'm talking about that is vague in the Autometer manual. They show that you do it with software on your laptop which you connect with a serial cable and a splitter that they...

    Just want to make sure there's nothing gone wrong in the Autometer wideband settings. As near as I can tell from the Autometer manual, you can change the volts to lambda relationship in what they call the "BGD Range Setting Mode". Then you can change that again in the ECMlink window...

    It's lookin' good!Not sure but I don't think it makes any difference. I noticed that STM gives the "head cc's" on the pages where they show Wiseco pistons for the 6-bolt and the 7-bolt engines. It's in the charts they show that look like they came right out of the Wiseco catalog. They are...

    Yeah I just looked through your Specs & Photos page and your build thread, looking for photos because I wanted to see what your intercooler piping looks like - and didn't find any pictures! Or pics of your mystery turbo. Maybe it is something known, like a Kinugawa. The pics they show now...

    ECMlink Help with tuning SD. What next?

    Well you are very near the maximum speed line, or at least what Mitsubishi considers maximum speed, of 145,000 turbo shaft rpm. That's determined partly by tip speed of the compressor wheel exducer and rapidly falling efficiency when you go past that line, and in some cases maybe the bearings...

    Can't ACL do anything right: a rant

    This thread brings new meaning to page 6 in the ACL "Race Series Application Guide 2023" where they have about half a page talking about the weird "Appearance" of these bearings when you take them out of the box. I don't think they mention embedded metal slivers though! 😝

    Looks like you made 24 logs on Friday alone! 🙂If it's a 16g, and if the airflow numbers in your Feb 23-24 log are accurate, then yup I think you are about one sneeze from the edge of the compressor map. So from that log I'm figuring 22 psi of boost. You are at about 2,300 feet of elevation...

    Yeah, lack of documentation for the Tip-in feature. They don't even show TPSDelta on the Loggable Parameters wiki page. They do have a few words about Tip-in on the Speed Density Setup wiki page, but it's just what we've already said.I'm not so sure the Tip-in software has what we need to...

    I haven't fooled around with TPS Delta but it seems to me that the stock values we have for it are so low as to be almost silly. I would guess the stock values are low because of emissions and fuel economy. I mean, you remember carburetors with accelerator pumps, right? Those accel pumps...

    1G 1gb quest for reliability

    The one Steve posted for M/T without alarm should do it for you, but I'll go ahead and post the one from the Chilton manual in case it helps you avoid any confusion. This one does show one other interesting thing - it shows an arrow going "To MFI System". This is the wire that goes to input...

    1G 1gb quest for reliability

    Yeah this is one of the things that happened on my car. The Start leg of the ignition switch has a hard life. It carries the entire amount of current (amps) that is used by the coils in the starter solenoid. That's somewhere around 30 amps. Check it out in this diagram. This is the least...

    Good! And here are my "few words" about the basics of it, without mention of the Pills.The solenoid is "normally open" meaning that when there is no electrical power to it, the air valve in it is wide open letting max air through. This bleeds air off from the full pressure line that goes...

    Like Justin said, this is a lot better than what you would expect from a 14b. I took a close look at the pic you have of your turbo (maybe I haven't seen the latest pic) and I sure don't know what it is. So it's some kind of "mystery" turbo but performance wise must be somewhere around 16g...

    1G 1gb quest for reliability

    There is a bypass test you can do that should help you figure this out. Sometime when the starter is not working, do this test. You need a few feet of stiff electrical wire to do this. Stiff would be like solid core wire of large gauge like 12 or 14 gauge house wire. It will be carrying about...

    ECMlink 1G Eagle Talon Has Fuel and Spark Will Not Start!

    Yes I was looking at that too.If we need to sort out whether the actual battery post voltage is getting dragged all the way down to 8 volts, he could connect a voltmeter of some kind directly to the battery posts. He would need to be able to shoot video of it, or at least be able to watch...

    ECMlink 1G Eagle Talon Has Fuel and Spark Will Not Start!

    Now that we can see your Battery voltage, I can see a very weird thing happening with it. While you are cranking the starter, the voltage is good, even high, it's about 11 volts, in the low 11's. But then after about 2 seconds of cranking, the voltage drops all of a sudden to about 8 volts. I...

    I guess if you have 1g pistons (7.8 to 1) it should be alright to try the 1g timing map. I was looking at it in your log with right click "toggle stock values" on the timing map, and the stock values are a lot more advanced then what you have in there now. You've tried the Evo8 timing map...

    That wiki page confuses me too. I don't know the answer. The only kind of reload I've ever had to do on mine was, when I first bought V3 new from ECMtuning, I had to update the firmware to get the flex-fuel code in it. Then I handed the whole thing off to English Racing and let them do...

    Yes. If you try that and it just doesn't seem to be getting us anywhere, the next and cleanest step I think would be to do what Steve suggested in the 2nd paragraph of post #34, which is to basically start the ECMlink configuration over from scratch with a clean install of Stock 1g DSM settings...

    That's what it looks like in your pic up in post #6, where it looks like the fuel pump outlet pipe broke through the end of the grommet which then got shoved all the way down to where the spacer would normally be. This is very interesting because I wondered if this would happen. But I don't...

    Try one of these fuel pump grommets on the outlet pipe of your fuel pump. These are genuine Mitsubishi.

    When you first put the 2g MAF on the car, did you then load 2g fuel and timing configurations to your ECMlink? The reason I ask is because Jeff Oberholtzer told me that "The 2G MAS puts out a Hz signal that is about 30% lower than the 1G for the same airflow". So the basic mapping of MAF Hz...
