Ok I know this might be starting harshly but here it goes....

What are the major differances between the 2... And (although personal opinion) which is better... And which is easier to work with???... Can they be used for V6 cars too or just V8???... Hmm Which has the better support in the aftermarket so to say???... Are they hard to switch over???...


I know I have alot of questions and hope I can get some answers to these. I do not know a freggin thing about cars comps but I am pretty good with P/C's and stuff... I just don't know if I should bother with my 6s' comp or not.

 

Kinda hard to beat GMs engineering. I don't know of one aftermarket co., that can match them for engineering.

I have a total of $175 in a spare ecm for may car, and that is with a whole new output section for P+H injectors. Also, have some other stock spares at $35. Kind of hard to beat those prices. I have no fear of a melt down stopping me a thousand miles from home. carrying a spare MOTEC, would be expensive.

Speedpro seems to be the only co., that actually tries to help their customers.
Electromotive, and haltech act like your bothering them if you ask a question.

Better meaning easy to tune?.
Well, easy means less to mess with. For a race car can be no problems, for a street car can mean poor manners. Also, a matter of the tuner, poor tuning, means garbage with any system.

If your running 8 Peak and Hold injectors the about the only answer is an aftermarket, or adding and injector driver *box*

IMHO, the best answer is a GM ecm with custom software.

 

I'm no pro at this, by any means. But I feel in my case it is a case of need over want. With a 383 at 10.5:1 comp306 cam, tpis miniram, and a T-56 it seemed like a good Idea in my 84. I'd have to replace the wiring anyway.

so I got an Accel harness off the board for $100 and paid $500 for the Accel ECM, 2stage n2o controller, calmap, cable, and a jumper harness.

All in all, I think it's worth it. I don't have to buy a window switch, run alot of un-neccecary wiring and have a new, clean harness to show off. Plus, I'm not worried about firing off the n2o too early and popping that $6k motor i just bought. And I've got full DATA logging capability with 32 channels so I can hook up wheel speed sensors and Drive-shaft sensors. Plus at 180mph it ould be nice to have on the shocks, I think. Anyway, it's on the way, and I'll be a regular on here.

I have the Electromotive system and never had a problem getting info or tech help by calling up the vendor(B&R in Az) or Electromtive direct in virginia.I either email them or call and they help me out,thats one of the resons I bought the system.The kit comes with a very good instruction and tuning manual to begin with and installation is a snap.I have heard not so good reviews on the Speedpro manual in fact.So the only tech help you would be getting would be from the vendor you bought it from,cause you never know what company owns the system IMO if you have the money in your car and have a lot in your motor do it right with the aftermarket systems,GM ecm may be a good system but find someone other than yourself to teach you,I dont think you would want to experiment on a ten thousand dollar efi motor as you wash the rings out of it,jut learning to tune it.I agree the Gm ecm can be on par with aftermarket units,but where is the learning maual?You would have to experiment before trying to do this on a new combo.I have heard far to many horror stories about people who supposidly knew their stuff and their tune damaged a new motor.My motto is :To get it right do it yourself.Reserch as much as you can and call the aftermarket companies

After you get to know speed pro, there is no needing the manual. ACtually, after having the speed pro and knowing what it is capable of and HOW you tune it in, the book is pretty good. I mean, it clearly explains what all the functions are, and what they do.

It however does NOT give tuning tips. Well, not true. It has like 2 pages. Your ECU is going to be custom tailored to YOUR car. its hard to write a manual for every application there is going to be out there. For every weather condition and so forth. That is when you seek the help of those that know and have done it. That is what I did to get on my feet now I feel like a guru myself. And I only have 2 or 3 months total experience in this.

It's nice to hear Electromotive is finally acting right toward their customers.
On the Speedpro, er now FUEL, one of the actual designers, lurks at www.turbobuick.com

You can gas wash the rings out of anything, doesn't make a difference what ecm your using. Also, starting out using efi on a $10K engine, with no past experience is kinda scarey in itself.

As far as horror stories I think most of that goes back to before we had any hacs of the gm ecms, and guys were flying blind.

 

Ive been to the turbobuick.com forum. Those guys are top notch over there.
