Megasquirt? What's the Situation?

[rkreigh]

base ms3 pro is about 1100 with the fly wiring that you need to install



you essentially take away all the engine management functions and there are issues with interfaces for mileage computer, security, ect...


gauges work fine. you for sure WANT to run coil on plug and I think the ecotec 4 turbo coils or the merc marine coils plug in perfectly


the megasquirt can drive the 16 injectors fine and has dual wideband, flex fuel capability, and a wide range of boost control and tuning features that make it a very good option for anyone that has "lost the dis"


the LT5 ignition system is quite good, and works fine, but since they are going up in price, the MS is a viable alternative. The raptor "plug and play" version retains the stock ignition system which I wasn't fond of as selling a "good DIS" will about pay off the megasquirt


I'm looking to do this, as the tuning opportunities are significant and the coil on plug is superior and much less hassle to maintain.


If anyone needs a DIS, reach out to me. I have one off my 95 and would for sure pass it on for the right price to a needy owner. Jerry is working on reverse engineering and will likely have a solution soon, and fortunately the DIS rarely fails. But when confronted with that, know that there are options!!!

Ron,

Ur saying the Ecotec COP fit correctly in the plug well? U got part #s? Of course u?ll still need to do a crank trigger unless u r saying MS will use the LT-5 crank signal.

The MS PRO natively reads the existing 8+1 crank signal.

And just so everyone understands, that is the price to buy the ms3 pro and do all the work yourself.

The DIYautotune plug and play version is 2400-2700 dollars.

Are they even advertising it as available?

No, you have to reach out to them.

With some people asking almost 2k for reman. ECUs, it's only a matter of time until these get more popular.

regular ecotec turbo 4 coil. It sticks up just about 1/8 too tall so a rubber spacer would make it snug


the raptor plug and play version continues to use the DIS which is silly.


the MS3 pro will drive the injectors, coils, dual wb, alchy system, flex fuel, and just about anything you can imagine. You do sacrifice some minor stuff in the CCM like fuel mileage computer and security control (you can keep it!!) and this would be a full custom install that has not been done yet on a ZR-1. But it's fairly clear on cutting in the fly harness to take away all engine control from the stock ecm and turn off the codes in the memcal.



I would love to just do one standalone style without the DIS box as the dis alone would pay for the ms3 investment to get started.


If anyone is in serious need of a DIS, look me up, so I can get started.

There is a tt zr1 using ms3 to control engine,boost functions with the stock ecm keeping CCM functions happy.

Works great.

Graham,
Is the MS3 also taking over the DIS functions?

[grahambehan]

No DIS in place.
