Folks,
I have a RamJet 350 which I have been running on a GM ECM 1227730 and I'm thinking of going to EZ EFI 2.0.

Does anybody know, or have experience, as to whether the EZ EFI 2.0 retrofit part number 30404-KIT will run the GM TPI engines including the timing and (of course) the fuel injection side?

I have asked of FAST but I can't seem to get a straight answer....it may be that the individual I am conferring with just doesn't know.....so I thought I'd come here and ask.

Thanks
jcj

Currently installing that kit. First thing you gotta do is remove all the old PCM wiring. Then you gotta change the injector pigtails(or buy the adapters), some of the other connectors(tps, iac...) get a MAP sensor(it doesnt have a MAF connector) and last but not least, get their Dual Sync dizzy. Then it will all work.

The Dual Sync dizzy, when set to the 50* retard, will adjust timing when need be.

I read the early EZ will not adjust timing but the newer version(4.0????) will. Make sure of the version. I would look at their site...

I would use dynamicefi.com (port fuel). Check it out. Especially the datalogging side of it. Your 7730 is a donor ECU.

Pretty bad when the company that makes them can't tell you.

Accel has a kit for the Ramjet. Here's a clip from an application I did years ago. Hope this helps.

I'm trying to find someone that has retrofit installed a FAST EZ EFI 2.0 in a GM TPI or at least find the instructions for retrofitting the FAST EZ EFI 2.0 to the GM TPI.

The way it is described makes the reader think that it is a plug-and-play for retrofitting into the GM TPI and since I know I can run the RamJet 350 on a 1227730, then if it is plug-and-play, I should be able to hook it up to my RamJet 350 without having to buy a new distributor.

If someone has retrofitted it to a GM TPI, then it would be optimum to know how it went, but I can't seem to find a write-up, a tech article, nor a video on retrofitting. All I can find is installation of the the full throttle body system.

I read the text from their website. It seems to me that it won't do spark with your stock distributor as previously mentioned.

The Accel Thruster will work with the stock distributor and give full timing control. Plus it has more features than the EZ. Just an fyi.

Thanks Ronny, I read that thread but I still can't tell if that EZ EFI 2.0 will just work with the TPI type distributor or if you need a whole new one?

I will write to the EZ EFI tech guy again and ask for the instructions for the retrofit kit and see what it says. I can't seem to find them online...all I can find is instructions for the their throttlebody thing.

Seems pretty basic nothing special. base timing-idle timing-vac timing optional-all in timing and all in at rpm timing.

I dont see crank timing. timing adv at low load(cruise) appears to be optional.

I think these systems are for retrofit carb applications.

dynamicefi looks pretty good. and has VE Learn with WB02.

Note that HotrRod Mag 12.2013 has an ad by Fast/EZ 2.0 that states "2.0 works with ALL ignition systems".

Thanks Ronny...yep, I have already printed that thing so I could read it carefully. Seems to me like I could use my MSD billett distributor(locked out) and my MSD-6 and run this system (see page 28 - 31), but is sure sounds like one convoluted procedure (and that's assuming I'm reading that correctly).

I wish I could get ahold of the ignition wiring diagram to see how it's supposed to work. If it is supposed to work with "all ignition systems", then one would expect it to plug into such.

have you checked into EBL? It uses your stock ECU as a donor.

I'm wanting to try something new with this self-learning stuff. Sounds fun.

I've done the chip burning and all that with the 1227730. I have the MEFI and the 1227730 wired in parallel right now. I did that in case I messed up my chip burning ....that way I could just unplug the 1227730, flip the fuel pump relay (one powers for use and the other completes ground path for use), and plug in the MEFI.

I was about to buy the EZ EFI (version 1) a couple of years ago, but I passed on it since it did not have timing control. I am quite curious about these self learning systems.

Remember the only part of the tune that they do is the base VE. You still need to plug in Air/fuels, timing, acceleration fueling and cold start.
And some don't have a floor or ceiling. What does that mean? Simple if you get a misfiring cylinder it'll show up as lean not rich so it'll keep adding fuel till it can potentially drowned the motor.

They're not perfect. AEM just came out with the new Infinity series of ECM. It has 2 internal widebands, an ungodly amount of datalogging and 129 pins. But guess what, no self learn. Too many potential problems.

Well, the tech at FAST told me I could use my MSD Pro-billet (locked-out) and my MSD-6A with this system. That's pretty cool since I already own those.

This link has the instructions in it. If you click on the tab INSTRUCTIONS at the bottom of the link, it will direct you to the manual for installation and setup.
Starting on Page 28 you can see where it describes using an MSD 2 wire distributor.

SO, I have to look at the wiring a little more, on first glance it would seem that the the FAST EZ-EFI 2.0 tells the MSD BOX when to fire ......well, if that's the case, can't I just wire the MSD BOX into my TPI type distributor and do the same thing? OR am I really missing the boat here?

That being the easy part. I chased AE for years. I finally have it 95% fiquered out.
