I have another question for you guys. I'm wanting to eventually ditch the carb and go with FiTech fuel injection. The instructions say you have to use a 2 wire distributor in order to utilize the timing control function of the unit. Can the tfi distributor be made to work in this application?

If I read the instructions correctly, their timing control function will only work with a magnetic pickup such as a Duraspark or MSD.

Well, that sucks. Do you know what my options are?
I bumped the timing to 20 degrees today and the car runs a lot better. I'm sure it would like more, but the idle follows the bump in timing. What I mean is, idle has gone up along with more timing. I backed the idle screw all the way out, but the idle is still high. I'm guessing somewhere between 1000-1500 rpm. I don't have a tach hooked up, so I'm just judging by sound.

Options on what? A magnetic pickup distributor? A MSD would be the most common and easiest to work with.  You could also modify a Duraspark or use a MSD type crank trigger.

You need a tach and need to figure out why your carb won't idle down.

I honestly don't get it.

I had a Summit distributor in it, but had to use the tfi because the Summit one's shaft does not reach the oil pump shaft and won't spin it.

Here's a short video.

Carbureted 302s used a longer oil pump driveshaft. The shaft on most distributors is long enough to reach the efi length driveshaft, but I guess the Summit brand isn't.

However, a carb length driveshaft is too long to use with an efi length distributor. It will bottom out and can damage several things.

So, pick your poison and use the appropriate parts for it.

Since I'm using the EFI distributor and need timing control, I went ahead and ordered an MSD programmable 6AL2 today. I'm going to keep the carb for now instead of going efi.

It wouldn't have been my first choice. The serial port connection is known to have compatibility issues when used with newer computers and adapters.

I would have likely recommended a Daytona Sensors timing control in conjunction with your 6AL, or even a MSD Grid controller with the 6AL box.

Well, I'd never heard of Daytona Sensors until now. That would have saved me a few dollars, but we'll see how it goes. I looked through many reviews on the MSD and didn't find anything negative.

From what I gather, its many of the same people who worked for/designed Crane's ignition systems, which had a really good reputation.

In recent years Crane and the ignition lineup have changed hands a few times. Comp Cams currently owns the ignition lineup and is selling it under the FAST brand.

I looked through many reviews on the MSD and didn't find anything negative.

Connectivity issues with the serial port is the most prominent issue that I read about when I was considering switching to that box.

I'd actually recommend finding a older laptop to use for programming, one that won't be connected to the internet all the time . MSD software has been known to have issues after driver or software updates. You may luck up and find one that actually has a serial port too instead of using USB adapters.

Its not just MSD, most professional racers that I know of have separate, non-network computers that they use for efi, ignition, data logging, progressives, and boost controllers. They only update or connect to the internet when necessary.

Ah, I thought they're box looked a lot like Crane.
I may just look into picking up an older laptop. I have a new one, so if there's issues, I'll try an older one. Thanks for the heads up and help!

Ok, so as luck would have it, my order for the MSD unit was cancelled. Tried calling Daytona Sensors and the lady gave me a cell number for a guy named Dennis. I just wanna make sure they're timing control is all I need. He didn't answer, so I left a message.

Talked with Dennis today and he isn't sure their unit will work. He said I'll be the first to try it with the tfi distributor. I went ahead and ordered one. Found it for $153, so if it doesn't work, I won't be out much cash. If it does, I'm golden. I'll let yall know once I get it installed.

The TFI module's negative coil lead should trigger the module input.

Right. I told him how it was wired, but he just hasn't tried it with tfi. Hopefully, there'll be no issues.

Got the TCS-1 wired up the other day and everything seems to be working great! Glad I went this route. Thanks for the suggestion!
