There are many systems available. Most are systems that piggyback on the factory EMS and others are stand-a-lone. Each will have it's pro's and con's and in that sense there is no easy answer to your question. Check this link on the Corral forum

Engine Management Systems - Corral Forums

To better understand the complexity of your question you will have to do some research related to each of the many systems.

why? what do you have going on in the car that you need that level of tuning? Just trying to understand your needs better so we can recommend a setup.

maybe I sould have been a little more specific also besides the tuning I meant installation alsolike how did the factory guages work and stuff I think i read somewheres in a previous post that I cannot find now that someone used the factory ecm still connected for gauges like the speedo to still work is that true? fox was a little easier but I am not so sure exactly

I have a 351w stroked with a ysi blower and low impedance injectors from a fox with dfi but its a gen 6 and none of the tuners around here wana touch it.so i figured id upgrade to either a gen 7 or a fast xfi setup. it made 850 hp before on race gas but I would like to drop down to at least 93 with a meth kit. since I have most of the stuff as a complete setup I didnt really think it made much sense to swap to the 94 specific stuff if I only really need a dfi setup. I do have the pms but id either need an injector driver or new injectors plus a new distributor at the very least

if I am wrong in my thinking please help sway my thoughts! I liked the pms but never got the drivability I wanted with my stroked 331 with strim and well now that engine is spread out over some road somewhere I thought sticking with the dfi would be better but if i am wrong well I am wrong I am still in the planning process and I just wana get this rite for the summer im tired of chasing stuff i just wana drive it finally!

there are a couple things out there like the big stuff 3 or the AEM or the FAST system. personally i like my PMS and if all you need is the injector driver and ditzy it would be cheaper than going another tuner route.

 

[shelbe67]

I did think about that but with the injectors I have I think I will peg my mass air meter and still need that also at that point I am halfway there to better efi system. I am afraid to buy everything and then find out that I have to step up in the end anyways. I am kinda in the middle rite nowI acn go either way. if i did go with dfi tho does our ecm control the factory speedo or is it independent?

 

[shelbe67]

ok I did some research and think I will just get a injector driver box from acceleronics and get a dyno tune with a chip the pms is nice but i think a chip will help and plus I can delete some stuff to that way egr and what not

Why the focus on canning the OEM system

Many have made it work with great results
with
PMS, QH, SCT, Tweecer

you are rite grady I wasnt really thinking I did some research and found an injector driver so I can keep my low impedance injectors which saves some money I found reasons i am gona go with a chip I have the pms and my car always seemed finicky so I am gona give up on it i think plus id like to delete emissions and stuff I was trying to cheap out a bit but either way it ends up costing the same
