Do I need more than Microsquirt?

[iniviate]

Older turbo 4 cylinder. E85, No A/C, not a daily driver.

I believe the stock computer was sequential injection. I don't care much about that.

I want to use a wideband and have a knock sensor. I believe microsquirt is capable of both with the correct controllers.

looking at this

and this...
http://www.viatrack.ca/

Are there better options for wideband and knock? i'm not real concerned with gauges, I'll be data logging pretty much anytime I drive the car.


So i'm looking at...

Microsquirt w/ 30" harness - $339
Wideband - $219
knock sensor w/ controller - $65
crank trigger - $70ish

Am I missing anything else? should I run MS2 or 3 over microsquirt and why?

Thanks!

How are yuo handling spark? Are there any fancy features you might want?

Take a look at the feature chart below; it the uS does everything you want, great! If you run out of pins, or a particular function isn't available, you might need to modify your plans.

If you're doing boost with E85, I'd look more towards the MS3 (MS3X specifically) or the MS3Pro. MS2/Microsquirt is capable of flex fuel but at a basic level.

MS3/MS3X can have a knock module added in.
MS3Pro has a knock module built in.
MS3X/MS3Pro allows for true flex fuel based on table blending. MS2/Microsquirt handles flex fuel as a single fuel and timing adder.

Microsquirt will do what you need but I think you'll be happier with an MS3 based unit.

Have I said it recently? The price difference between MS3 and the lessor variants is trivial if you are willing to assemble the kit. And, if future trouble-shooting is needed, is the schematic for the Micro even available? Size and weather-proofing are the only distinct advantages that I see for the Micro, and those don't usually matter for a car/truck install.

The price difference between MS3 and the lessor variants

That's why you buy instead of leasing, even with the lesser variants.

is the schematic for the Micro even available?

In the manual ...
