megasquirt... ewwww.

sorry, i come from import world, and a TON of Z car guys use it on turbo and small block converted early model Z cars.. i hate it.

I am running a Megasquirt II controlling fuel and spark and It seems just fine to me, not to mention I have only $600 into the computer, relay board, and wiring. I could have spent even less if I was to assemble it myself.
Theres a guy, Parish i think, who is running a megasquirt on a chevy pickup with a single turbo lsx motor making over a 1000hp to the wheels. It works great for him.

To say that BS3 has great software is a little...optimistic. I have seen it and it looks like a bit cluncky to say the least.I for one am not a fan of an ECU that encorporates a wideband controller. I have had nothing but great luck with the FJO units and will continue to use them. By having an external wideband controller you are not putting all your egg in one basket. If the ECU takes a crap its not a total loss. The side benefit to using the FJO wideband controller is the ability to use either the Bosch sensor or the NTK sensor. The Bosch sensor is inexpensive and works great for unleaded fuel. The NTK is a must when using race fuel, if you want to sensor to live.

If you like to tune on the street I agree. The FJO is a great unit. The BS3 software isn't that bad...at least it's easy to use than a Motec. :lol:

I think for someone that is a first timer or doesn't want to spend alot of time learning how to tune the BS3 is a better choice. Heck the 950 Holley is almost brainless but doesn't have anywhere near the options of the BS3.

Yep I believe Jim is running a Megasuirt piggyback on top of LS1 edit and the stock ecu. The truck is fast and fun to watch on the street.

For everyones benefit, can you please list the features that the BS3 has that are not present in the Commander 950 system?

Thanks,
Andrew

They've got 75's now, I have a set in the garage for the GTO. Problem is now I'm going to BS3 and will have to buy some low impedance units.

Here ya go. I'm not a BS3 expert by any means...

If you are not an expert, then how can you make claims to BS3s superiority? The truth of the matter is that most of the features that are listed on the sheet in the link above focus on:

Coil on Plug ignition
Sequential Ignition (and the features that can go along with it such as individual cylinder trim)
Staged injection

The Commander 950 has some standard features that are options on BS3, like internal data logging.

So for a normal guy, that has a traditional engine with a distributor the Commander 950 is a much better value. This is especially true considering the comprehemsive manual that is included with the Commander 950 system.

And if you are running an LSx based engine or another engine that requires Coil on Plug support, then a nother great value is the EMS system from Australia.

Where did I say the BS3 was superior? Oh that's right I didn't! I believe the thread topic is about a comparison. I am giving my opinion just like you are. So guess what no one is wrong in this situation so chill. :rolleyes:
