I'd like to know what "batch fire" is, what the difference between sequential and non-sequential is.
Here's the thing guys, a lot of people say, "oh, you don't really need that". For example, a guy is puttting a WRX motor in a bug, and he's asking about the turbo's water cooling system. One guy writes back "oh, you don't need that". That's retarded. Why would someone go through all the effort of designing something that wasn't really needed?
I'm a little worried that there are some of those people posting here. I'm looking for a VERY reliable system to run my car. I don't want to have my head running hot, my timing advanced "just a little" too much. I want a powerful engine that will run reliably and propery whether it is cold and rainy outside or it's 110 degrees. I know the engineers that designed the stock ECM thought about those issues. I don't know if 034 EFI or MS did, but I'd like to choose the one that would run my engine in a similar way as a stock ECM, albeit with much higher output. I understand that asking for more power from an engine than it was designed for will decrease it's life, but I certainly don't want to run a EC system that will contribute to it failing prematurely.
The whole reason I've gone to all the trouble of installing a 1.8t mid-engine in a crusty old bug is that I want reliable high horsepower, and I want it to be Volkswagen(I know, I know do a VR6, I still can, don't worry) So, if sequential is something that contributes to it's longevity, than I want it. If batch fire does the same thing EXACTLY, great. I just don't like cutting corners. This isn't about cost, I've spent $5k just on my front suspension alone. It's about the right product for the situation at hand.
Mk3North mentioned Unitronic to replace the immobilizer. This is the first I've heard of it. How much is it? I have an 02J tranny, where does the wheelspeed sensor get input? How well will the stock ECM run when some of the inputs are missing? If the Unitronic piece is inexpensive, I can wire up the stock ECM to run for now. But if it's not cheap, then the standalones look better and better.
If you are selling stuff, your really not an unbiased poster. If you can make unbiased true statements, then I'd like to hear.
I had aircooled motors for years. Constantly fixing one thing or another. I want to install this motor, tune it up, and drive the bejesus out of it for as long as I want, and not have the ECM be part of the problem. Besides safety and emmissions, does the 034 and MS take into considerations the same sort of data the stock ECM does?
You guys are awesome, I didn't expect to get such good feedback from so many sources, thank you.
