I've been running a RamJet 350 with a 730 ECM. I've been considering going to EZ EFI just to let it take care of itself.

Anyone know if I can just use the TPI retrofit kit?

I know it doesn't control timing.

yes you can. if im thinking correct the ram jet i layed out like the TPI and you will need the 302000 kit. as for a distributor, a DUI 14000 pn as this will be a narrow style dizz like the TPI style but runs like an old style HEI.

when you get the kit and you place the ECM inside like i did you will need to extend the o2 lead.

BTW, if your car is a 90-92 you will still have to keep your stock ECM in place and make sure its getting power so your cluster will work being they intergrated alot of stuff into the ECM that werent in the 85-89 years.

after you get everything wired, running, and sorted you will be VERY happy with the EZ system. i'v had mine installed for almost a year this up coming weekend and love it. i cant get the full use out of mine yet because i built it with too much compression and i cant throw much timing at or it will seriously detonate.

which is why im building a 383 with much more knowledge on my side. ya have any further ques just ask.

BTW, you CANNOT run any power adders with the EZ. for the cost of what the EZ does, ya cant beat it.

Pm'd you.

There is definitely some applications where the EZ can be a good alternative.
But given the mild combination in the Ramjet, they're easy to tune. Many systems can come with a base tune that will be very very close for that reason.
And being able to control spark is huge. On the better systems you can pull spark out as the temp rises, making it less prone to detonation. In addition most have the ability to do some sort of power adder, and don't necessitate having to change distributors etc either.

Thanks all. I've been burning chips with an Autoprom and TunerproRT. Just considering moving away from that and letting the computer do it all.

i doubt yours will be much diff being (im assuing)its a 90-92 car but when we set up my EZ NONE of the connections, fuel lines or anything went outside the eng bay for setup.

there are about 8-10 wires that you actually have to locate a home for, all of the other connections are already built on the harness.

amazingly everything tapped into exsisting harness's and relays. as for the Holley, MSD, or any other system i cant speak for them. i will sugguest that you do like we did and lay everything out on the eng, get it plugged in without making any alterations and get it running. then after its up and running and you have a idle baseline programmed then route the harness in a running form.

I'm fixing up a 350 block to drop in my 92 firebird v6. What exactly am I supposed to do about the ecm when I'm using the EZ system? An also, im going to use the base EZ kit, so what about my distributor? Can i run an aftermarket MSD distributor?

This is what I did. Get the port injection mod. Easy to tune and works very well.

What fuel line are you using? Did you have to change the stock one? BTW: do you know what the stock diameter is?

I found the easiest to work with and (reuse) as well is Aeroquip push fit EFI fuel line with PF AN fittings. Tthey also sell a compression fitting to mate with stock hard line. I think the hardline was 5/16 and 3/8 O diameter. just measure it with a caliper.
