I am using the SM2

Okay, here we go again. . . . . .
Originally posted by MakoDHardie I didn't know so many people were using cheap ecu's and band-aid tuning devices on this forum. I guess I haven't seen many threads on piggyback fuel controlers lately. I wonder why... You might want to look around and check out what people here are using. Most of us who have decently modded cars are running stand alone ECU's, even before the injector sizes are changed. And sure, with the right management, you can run 1600cc injectors in the primary rail. Its just not necessary unless you are running a very high boost setup that would normally require additional injectors beyond what the upgraded rails and usual 850/1600's can put out (ample support for more horsepower than most forum members are making). Be careful how you defend your preferences. The responses weren't questioning the integrity of the Autronic unit, they were meerly asking why he chose to go with a different setup that isn't normally recommended by knowledgable rotary tuners. There's no need to talk down to anyone here. If you're feeling the need to, your place is not in the 3rd gen section, or any other part of this forum. Try some other place where they actually use cheap parts and are unfamiliar with stand alone/programmable management systems. BK |
Sorry, I didn't know you'd take it so personally. I wasn't trying to tell you that you were wrong, but you may hurt some peoples' feelings when you tell them that the $1300 unit they just bought for their car is crap.

Ok, Jetenginedoctor, you can relax. I understand what you are saying. And yes you are absolutely right. I only posted back first here because I thought you were calling Haltechs and PFC's pieces of crap, since those are what the majority of us are using. I didn't want to start bringing a bunch of tech into here because my point wasn't to argue with you on your own level of knowledge. Since you are marketing Autronic EFI systems, I didn't see a point in even trying.
Motec, Autronic, Haltech.... all those computers represent the top end of performance tuning computers. The only reason so many of us do not go with these units is most likely because the PFC does its job and without having to change out the stock sensors. Just two months ago, we had a T2 at my house getting a new motor and wiring up the Haltech was probably the most difficult part considering all the extra hole tapping required to install the Haltech sensors. For those of us who are not that ambitious with such a project, we find ourselves satisfied with the results of different management system that doesn't require custom wiring. But at least give us credit for going stand alone. I didn't mean to come across as if I was saying 4x1600's are wrong, I was just saying that the amount of fuel they are capable of putting out is more than is necessary after forum members questioned how well the unit could idle such large primary injectors. Since he does have the right unit, he's kickin ass on his investment. And it's deffinitely way better than going with bored 1300cc injectors or a primary housing that's been machined to fit larger injectors because both have reliability problems. Real 850's and/or 1600's is the way to go. Stock 550 primaries and 1600s is a more reliable way to go than a 1300 comination, especially if the primary rail has been modified. 4 same size injectors is an awesome setup and I'm sure purely capable of awesome results with the right ecu. Zach is deffinitely running the right gear on his car for what he's done with it. I didn't say that 4 same-size injectors is wrong, but the duty cycles of the 1600's in the stock primary locations will be pretty low unless you have some really quick-spooling turbos. They will at least be low enough to show that for the primary induction ports, you could achieve intake fuel saturation with smaller injectors than 1600's. It doesn't mean for any reason that you should or its right or wrong, just that it may be a trade off for the tuner's preferences in some way, ie: taming the car's idle. As for Zach's setup, it will not be an issue given that he has the correct support for it and the tuner does indeed recommend it. I'm sorry if what I said came off the wrong way. This is Zach's thread and there is no need for us to high jack it with this argument. Zach, you have a nice setup and my intention wasn't to appear negative towards your choices for fuel and management in anyway. I've read back through what I wrote and didn't find anything that may suggest that I do, but just incase, I appologize for starting an argument on your thread. |
For the record, I sell both Autronic and Haltech products. So, it is fair to say that my statement is without bias based on brand afiliation with only the Autronic line. However, I will be the first to say that the difference in refinement between the venerable E6 series of Haltech ECUs versus the Autronic ECU that Zach is using is quite shocking. That's not to say that the Haltech ECUs are not good, as they are very good considering their cost. There is a big difference between any ECU you buy for one in the $1000-$1300 range versus one that costs $1800 or more. Zach will now have much greater control of his engine than his old E6K could ever hope to give him.
