![]() It take a lot of online digging to figure out what is going on and how to correct it, but that was a MegaSquirt thing for me years ago too.This has taken me some time to wrap my head around, but I setup a histogram in the VCM Scanner that shows me what g/s I'm at with respect to MAP and RPM. The spark table is in grams/second instead of kPa.Like I would even be able to put 22pis to the ground in a 2wd 60's half-ton with 245 tires. Boo hoo, I know, but I guess had my hopes up too high. My drive-by-wire P59 ecu doesn't have the architecture to run 3-bar MAP.LOTS of options, and with a lot of online resources, relatively straight forward to tune. The more I've dabbled with HPTuners, the more I'm getting used to it. I have my '61 Chevy running and driving with the LQ4/4L80E/7875, all mooching off the (adjusted) factory tune with HPTuners. Update just because I stumbled onto this thread searching for something LS ECU-Tuning related. There is likely other tuning software out there as well. I am a long ways off from having to worry about it yet. If I can't find a "mask" for my ECU, or if I cannot change the bins for 3-bar, I will likely shell out for HPT. I have no experience with TunerPro other than this, but I figured it out, and since forgotten most of it (sold the car in '19). If you can do Megasquirt, this isn't that far off. In my case, I was using a antiquated ECU that nobody had developed further, so I spent more time figuring things out and adding more notes. If the dude who created the "mask" was kind, there should be lots of notes to help you know what to do or change. The software itself was a bit confusing at first, but you eventually figure it out as you poke around. ![]() adx file (what you are going to datalog), and ultimately you create an. xdf file (the "mask" to interpret hexidecimal into English), an. My '07 Express ECU came DBW, but apparently has the hardware in it to run IAC. The drive-by-wire vehicles often don't have the IAC driver because the throttle is the IAC. They almost all have the drivers for IAC and flex fuel. There are sites that list ECMs that do and don't have the IAC controller. I used to have pages bookmarked but can't find them. You won't necessarily be hooking it up to a USB and your laptop, but the level of control you have with a stock ECM is not something you'll find in aftermarket stuff. This generally means "6.0 van".Īll of this. You'll be wanting a '99 up computer if you want to control a 4L80 and you'll also need to make sure it has the IAC control circuitry. maps that are the part of aftermarket computers that are so hard to get right that most people just ignore them and live with an engine that occasionally runs like crap. Engineers slaved over all sorts of obscure tables to get the tune right, and it's those obscure idle, intake manifold wall wetting modeling, temperature compesation and modeling, etc. Tuning requirements will be minimal and it's far more robust and sophisticated than aftermarket computers. Stock ECU is not only easy button, but best button. ![]() If you see yourself going down the rabbit hole, Terminator X Max. While I built the engine for 22psi boost, I imagine I will be too scared to even approach that, much less need meth injection, on a street-driven 60-year-old 2wd pickup. ![]() It starts adding to be almost on par, but as mentioned above, it's going to depend on how serious you want to get. BUT, it comes with a wideband, can serve as a boost controller (which would be $600cdn), meth controller ($400cdn), and traction controller (?). The Terminator X Max setup in DBW and trans control will set me back $2000cdn. Add an electronic boost controller and Meth injection and it starts adding up. Add to that a wideband for $300 more, and I'm in for $825CDN. HPTuners will set me back $525CDN for the kit and credits. Since I'm still intending to run a stock cam, keeping the stock tune (just scaling it to fit a 2 or 3-bar VE table) makes sure I maintain all the perfection that GM provided as far as economy, cold start, driveability, etc. In my '61 Chevy pickup I have an '07 LQ4/4L80E drive-by-wire pulled from a van, to which I've added a 7875 turbo. Interestingly, I am in the exact same boat.
