As the title suggests, does anyone have charts for the sensor ranges and matching output voltages for things like the MAP and oil pressure sensors? I can't believe it's this hard to find that info, but I'm not having much luck so far. I was hoping I could pull it off of a datasheet from...

As the title suggests, anyone out there running a Megasquirt setup with the internal knock module? Finally found someone making a drop in replacement since DIYAutotune has been out of stock on them for the past 2+ years and took the chance on them. Will be a while before they show up, but I've...

As the thread title suggests, I'm looking for some feedback on what people might be using for traction and launch control on their setups. I know Goody had a thread a while back showing the differences on a Cuda 3G swap, but curious if anyone else has played with it at all. I'm mostly just...

So I recently swapped the old MSD Hemi 6 off my 5.7 and upgraded my Megasquirt setup to an MS3X to run full sequential and spark control in a single box. Generally speaking things are running pretty well, but I'm having some issues working out some reduced power over my old setup and a really...

Hi all, I'm gearing up to swap my MS2 setup to a full blown MS3X at some point in the near future and am trying to plan ahead as much as I can for all the extra inputs and outputs and options I'll get to play with using the new computer. One of the things that I find the most novel to...

As the title states, is anyone running aftermarket A/C systems with their Hemi? I've been looking into a Classic Auto Air system to put in my 67 Dart to make it a little more all around cruiser as the summers here in Kansas can get awfully hot. I've got a bit of a unique setup, but I think I...

So this could probably go in several forums, but I'll toss it here since the Hemi swap is what ultimately drove me to it. For the quick version of the background story, I swapped a 5.7 Hemi a few years back in my 67 Dart. Originally went with a carb (didn't get computer and harness with...

I know this has come up several times, but it seems there's some information out there now that I'm hoping someone can share. I know the Megasquirt is capable of using knock sensors, but the factory knock sensors on the gen 3 Hemis are a little weird by some standards. They're not the typical...

So back a few years ago when I first decided to do a Hemi swap I watched the video on Inertia's website for the SRT Max Rumbler cam and knew that I wanted that sound in my car. At the time of the inital swap I didn't have the money for the cam and kept telling myself I'd save up and do heads and...

So I'm finally getting around to installing a new cam in my 5.7 swap and had some questions regarding rpm limits. I've read a few things through the years of following the 3G Hemi design, but a Google search becomes problematic because most people are limited by the factory engine controller. I...

Wondering if anyone out there has an on-head valve spring removal tool they would be willing to let me borrow? Something like this http://www.cranecams.com/product/cart.php?m=product_detail&p=25310. My preference would be someone local to me (Kansas City/Topeka kind of range) as I have a cam...

For those out there custom tuning or with access to scanners and the factory tables, what sort of AFR are your 5.7s set to cruise at? Even with the addition of my new 6 speed, my mileage has not really improved. I've fiddled with the tune a little bit and leaned it a tad, but I'm not sure how...

So I think I've given up on my Weldtech aluminum pan that I bought originally for the swap. Every time I think I have the leaks and cracks fixed it seems to be leaking from a new weld or my patch cracks again. That being said I'm looking into getting a steel Milodon pan to replace it, but I...

Well, I finally managed to get a few runs at the track after my swap. They weren't super impressive, but they're not all that bad. I'm moderately pleased, though I know the car has more in it (5.7 with stock internals, Indy Mod Man intake, TTI headers, and Megasquirt fuel injection, ~3400 lbs...

So I've been debating seriously looking into a later model 5/6 speed trans swap in my 5.7, but I'm not sure what all to look for. My current setup (a stock 833) cruises around 3200 doing 70 on the highway. I looked into a Gear Vendors, but the .78 ratio only drops the rpm to 2500-2600 cruising...

So the track opened tonight for the first time of the season for some test and tune, and now that the Dart was running good I was ready to see just how good and hopefully finally put some numbers to the build. As I was waiting in the pits for my dad to show up and to take the car to tech he...

Check out the fun new switch that got added to my car. I like to call it my volume switch, lol. I'd put a little sticker next to it with a Vol + Vol - text, but I don't have room. It controls my new electric cutouts I got from DMH Performance. They are fully adjustable for however long you...

As was mentioned in a separate thread I would like to try to get a new source going for anyone who would like to share and help out others to get their engines up and running and tuned to run like they are really capable of. Uhcoog1 has generously offered to host tuning files for the time...

Does anyone out there have a stockish 5.7 Hemi running on a Megasquirt that would be willing to share a base fuel map with me? I know that the MS has some decent initial setup capabilities that take the engine size and whatnot into account, but I know there has got to be some tweaking on top of...

So I hope to have all the pieces to my fuel injection puzzle coming together in the next week or two and I got to thinking that there's no reason I couldn't get all the wiring done ahead of time while I'm waiting on parts to be delivered. I know that the Megasquirt main computer at least needs...

Was wondering if other people out there using the MSD Hemi 6 could give me a hand with my MAP sensor readings. I've had three different sensors hooked up to the car and the readings just don't seem right. The original sensor that came with the engine only read around 12.x psi pulled out of the...

So maybe this is more appropriate for the electrical section, but it does apply to my hemi I suppose. Does anyone know a place that sells factory connectors for the different sensors and stuff on the new Hemi? I called the dealership a while back when I needed to get an alternator connector...

Looking for some advice into setting up the timing on my 5.7. I've been fighting a nasty cut and bog on full throttle hits ever since I got the engine in the car. At first I thought it may have been a carb problem, but I tried all the accelerator pump settings and some different step up...

So is anyone out there running an aftermarket tach with an MSD 6 Hemi box? I have a little Actron Acrotach I got at a swap meet and like the small form factor, but when I hooked it up to the 12v yellow tach line from the MSD box I'm getting nothing out of it. I know MSD sells a bunch of...

So I finally decided several months back that I was going to do a 5.7 hemi swap in my 67 Dart. The more I started working on the car, the more I realized that it was a stretch to call it a 67 Dart, lol. It has a 69 grille and sheet metal, the rear end was originally out of an F body but I...

So I finally got the 5.7 all in and ready to start trying to get it running, but I ran into some issues tonight when I was first cranking it over. I filled the oil pump from the external fitting and rotated the engine backwards as suggested elsewhere in these forums, and it pulled the oil down...

I feel a little silly asking this, but I've looked around and can't seem to find the oil capacity for the Weldtech 5.7 swap pan. I got mine off of Ebay and didn't get any paperwork on anything with it. Their website doesn't even seem to mention it. I know it's similar design to the Milodon...

So I ended up just biting the bullet and getting a set of TTI headers instead of trying to mess with the stock manifolds. That being said, is it possible to install them with the engine in the car or do you have to lay them in the bay when you drop the engine in? I assume I can't bolt them up...

So after reading up I found that the stock LX 5.7 manifolds won't necessarily clear the engine bay without modification. Since I'm not experienced with frame modification and plan to put headers on eventually, I'd rather not deal with cutting anything up. That being said, would anyone be...

Anyone have some suggestions as to how I should setup my carb for my upcoming 5.7 swap? I plan to use the Carter Competition AFB that's currently on my 318. Assuming the carb hasn't been taken apart and changed at some point in its life, the stamping numbers indicated that it is setup as...
