I do not have time to write everything about the system, there are plenty of sites out there that can give you all the details, and specs.

So, the haltech p2000 platinum is unimpressive in your opinion, perhaps you can spend the time to explain to me why you think this is so, and the advantages of the other systems over the haltech.

Are you guys doing MAF cars?

Mass Airflow systems are clearly superior to speed density sytems for starters...All or most of the features you listed about the Haltech are available on the other stuff and it seems much more user friendly and plenty powerful enough for people like us. I've done the edelbrock EFI which really kind of sucked but worked ok I'll bet their EFI2 finally caught up(looks that way), The hardware on that system was actually very nice, and Now the Accel Gen 7 which is extremely powerful with more features than I would ever have the time or energy or brain to use...I looked at Motec stuff and it basically scared the crap out of me because it is too freaking complex. Maybe your an engineer or software developer or even a Fuel injection specialist in the automotive industry? I know one thing, it's an extremely formidable task to tune an electronic fuel injection twin turbo small block chevy to work like a factory car...it will shrink your brain to the point the project is not only not fun any more, but mostly a complete waste of your life and resources!

So you want to spend thousands of hours testing to optimize and program? I can't tell how many times I had wished I had just put a freaking carburetor on it. I gave up and took it to the professionals and they couldn't do it very well either...oh, it worked ok, but nothing at all like a factory tune...WOT is cake, idle is a not that big a deal, all the stuff in between is a nightmare...hot restarts, cold mornings, blazing hot summer afternoons, transient fuel situations, iac issues, spark timing control and programming, humidity, wild temperature fluctuations in the motor, running AC, Vs No AC heat soaked situations at Normal Operating Temperature, Racing conditions at a drag strip Vs. A road course Vs. just driving on the street. State Inspection and A:F ratio's...Cats vs. no Cats and how that effects the tune and how much you want deal with that every year whatever you decide, Keepiing your eye on the ball...what the hell the motor is even going to be used for most? Daily Driving, Drag Racer, Road Racer, Long Haul Touring, Short Commutes in or out of traffic, Long commutes in or out of traffic? The list goes on forever and it seems only a team of engineers can do it WELL.
By the time you might be getting somewhere you have a hole in your piston, a bent rod, a turned bearing, or some other stupid failure/dealbreaker. I shopped Haltech and Motec...both of them way too Complex for me.

I can do it, but I can't do it well...Hope you enjoyed your

Good luck with your aftermarket fuel injection system, I'm gonna avoid it like the plague for the rest of my life unless something changes...the money and time spent just to try or do one of them is far from trivial. Got it in the *** so hard so many times with this junk, I don't even feel it any more. I had a little fun and learned volumes, but Like I said, I'm not into it any more...it's a shame, because I feel like I know a lot, but far from enough to really build something worthwhile. On second thought, It may have been easier to do a naturally aspirated car. I'll stop now, the popcorn is done.

How 'bout this: " I've spent a lot of money on turbo systems for gas motors, aftermarket fuel injection, and modification of perfectly fine factory automobiles...the rest I just wasted " ! Maybe that should go on my headstone?
