    Can anyone adjust my tune for 42lb injectors? SCT X4 tuner

    You need the actual software to make the adjustments you need. Call whoever is going to tune it and ask for a starter tune.

    Best upgrades for fuel system? 00 GT 4.6 2v

    That's a really broad question and this probably isn't the right forum to ask that. But the two main things we need to know is what is your budget and what is your goal? Are you wanting to upgrade just to upgrade? If so it's a waste of money. If you have a goal in mind we'll need to know. I...

    Cold start surging (data log included)

    Is there an indicator for which way it needs to go? Or something to look for in a log?

    Cold start surging (data log included)

    Was the engine fully warmed up when you adjusted the VE?

    Cold start surging (data log included)

    I've been having a similar issue with mine. I can't look at the tune currently, but I did find raising the cold portion of the Initial Values table under idle helped a lot. You'll also need tweak the Warm Up Enrichment.

    Cold Start

    So this is where I talk about my learning process and talk about where I screwed up. I was watching the Accel indicator under Engine State Settings while I was driving. I didn't realize there was a TPS Accel indicator on the main screen. Once I saw that I realized I was in the wrong spot. So I...

    Cannot figure out why my engine dies at idle

    If they're legit SD 60lb injectors I'd say you're good. I've tuned with them on a couple different set ups in the past and they worked really well.

    Cold Start

    I'm guessing that's with the intake in the engine bay. Plus an aluminum intake sitting on top of a hot engine while soaking in a hot engine bay doesn't help things.

    Cold Start

    I've always had an intercooler of some sort. I've had friends run meth in the past with no intercoolers and things got dangerous.

    Cold Start

    The inlet sensor is in the back of the blower base. It's reading the temps after the intercooler. Depending on ambient temps I can see cruising temps between 100-120. On a cold day (70ish degrees) it'll show even lower. I attached a log that I pulled from the SD card a couple weeks ago. It...

    Cold Start

    Everything is conservative because I'm running 18psi on 91 octane for now. I did recently change to a colder plug after having some knock issues at WOT at higher timing. I've always set up WOT with locked timing. Maybe it's just an old habit from my SCT days. I tuned the accel by feel. Those...

    Cold Start

    I'm finally getting down to the small details. The current one is the cold start. For the first start of the day the RPM will fluctuate a bit before settling down. I tried to get that in a log, but it was just a little too warm to hit that part of the WUE table I guess. Once it settles I can let...

    Pop and bang tunes...... best and safest way to make them?

    That's really a lot more simple than I thought it would be. But makes sense. Load up the exhaust on fuel. Like in the carb days when guys would turn the key off while coasting then turn it back on and BOOM! My dad said he went through a couple mufflers that way.

    And I'm Back

    Did some driving today and tried to keep an eye on things. I didn't think to datalog and I cleared my SD card. But I played around when I was on the freeway a little. When lifting off the throttle while cruising the A/F would go a couple points rich for a second or two then go full lean. If I...

    Model Engine Run by MS2

    Hopefully this link works. And I hope it's ok posting this here. I figured it went here since the description says its controlled by an MS2. Pretty impressive IMO. View: https://www.instagram.com/p/B9N-Rkang-S/?igshid=87vjy494jwr9

    And I'm Back

    It's been a few weeks, but I remember before when I would lift off the throttle, say like coasting in traffic on the freeway, it would go rich. Like into the 11's rich. But after a second or so it would come back to commanded A/F. I'll have to double check when accelerating, but I remember it...

    And I'm Back

    Even if it goes rich when I lift off the throttle? I'm guessing there's an adjustment somewhere else I'm missing.

    And I'm Back

    I finally got to drive my car again today. I learned the decel adjustment is really sensitive. I had it at 75% and every time I would lift my foot off the gas it would go full lean. That made shifting really interesting. It looked like I didn't know how to shift. Does anyone have a good how to...

    My first microsquirt project

    This is a pretty cool project. And it's cool to see how versatile the Megasquirt setups are.

    And I'm Back

    After almost two months I finally got my ECU back from DIY. I put everything back together today and of course it doesn't seem to be working correctly. I swear I had this thing pretty dialed in before I sent the ECU off. So I have a couple quick questions. First is about the flex fuel sensor. I...
