I checked out FAST but you need an adapter harness for just about everything. I need something with boost managment and datalogging capabilities.

Searches had nothing for the words plug and play or other varients of it .

thanx a bunch

 

untill the auto manufactures all switch to one universal wiring and connector system , an aftermarket efi system is always going to need an adaptor harness. The market isnt big enough to make a seperate ecu that will plug directly into all the popular combinations. whats so bad about using an adaptor harness?. Or you could always use a standalone harness and ditch the factory wiring.

I am looking for ease of installation. FAST uses a whole new harness, which I am not into doing really. I don't mind an adapter really ... just don't want to be rewireing all the sensors and crap .

 

I think Painless offers a direct plug in.

 

There is an advantage with going to an all new engine harness. It replaces the 25 year old stuff for one. It also gives you some freedom to reroute the harness in a cleaner way. I made the complete harness and XFI FAST swap in my Grand National and it was the best thing Ive done.

The XFI also does everything u want, can be switched from car to car if you decide to sell and its field flashable-upgradeable.

 

My holley commander 950 came with a new harness. I only had to run power and ground, and splice one wire to the fuelpump relay. The rest just plugged right in! I installed the harness in a couple hours and I was up and running, rewiring of the sensors was not required. The part that took up most of the time was drilling a 2" hole in the firewall with a dull holesaw made for cutting wood.

I removed the holley commander system a year later for some work on the motor and I had it reinstalled in like 20-30 minutes. Just trying to state that those standalone harnesses aren't NEARLY as difficult as they seem.

I'm sure you know about the $58 code. The ultimate in plug and play. I'm running it without repinning anything at all on my SD TPI harness, not that repining is hard to do either, I would just cut and splice since no one will see it anyway.

I think it was Motec that used to make an ecu like what your looking for. It was called something like GM6E. or was it Haltech?

 

It's the haltech E6GMX. Now, the real question is does anyone know whether or not somebody makes an adapter harness for this ECU to adapt up to the speed density TPI ecu? I only ask because the haltech piece uses only 1 32 pin plug and the speed density ecu uses 2.

 

Check out White Racing:

They have adapters to match a FAST or Accel DFI with the factory harness.

 

I have a Haltech E6GM ecu in my camaro it does indeed run speed density, it has two plugs, 1-32 pin and 1-24 pin where as the factory sd harness is three plug. I took a throttle body harness witch is sd and added eight injector plugs to it and lenghted out the tps and iac wiring to reach the front of the tpi engine. The E6GM has factory plug sockets, but some wiring does have to be repinned, like injector grounds, fan relay, and maybe fuel pump signal. It does have datalogging capabilities, tune on the fly, and two accessory plugs for boost or extra map sensors and so on. Its kinda old school because it runs on MS-DOS, but its easy to work with, MS-DOS dosen't lock up like windows has the tendency do either. So far Im happy with what I got, sure beats burning computer chips, and its one of the more affordable systems out there. good luck hope was of some help to ya.

 

how would the superram ecm combo summit has hook up? I do indeed want ease of install but when I rebuild my 350 I dont wanna have to do the prom jig..

 

thanx for all the info all . I regret to say I have a 165 ECM with the $6E code right now . I will be tossing the turbo in this spring .... but I don't think I can get what I need/need to learn in time . So for now I am useing the prominator pro ...and hopeing to at least drive it , without blowing it up.
