Default Megasquirt 3 from EFI source engine dyno testing

never worked on an engine dyno before but it was awesome to mess around on one with 8 widebands and everything in it.


nice pretty headers before dyno pulls, haha ready for paint to go away




oh yeah really pretty now haha


the ms3x box from EFI source for LSx engines is working amazing.
tuned this stock LS2 from a GTO and it made 460hp 450ftlbs of tq.

Nice, my older brother had an engine dyno for 8yrs and I loved watching dyno pulls! Awesome to see 1,000hp just sitting there.

yes this box and trans control is being developed by EFI source.

we are dropping a 5.3 single turbo into my friends nova possibly this weekend, and we will be using this same box on the car.

cant wait to fire it up and drive it around.
that will probably be one of my first initial how to start and fire and tune an MS car video's

i would love to do one on my friends MS1 car also

Did you notice the back two (or any really) cylinders being leaner than others with the 8 widebands? I hear alot about it with the ls1 intake manifolds. Just curious.

well this is an LS2...
the intake is different from an LS1.

they were all pretty god damn close haha #3 was actually the leanest, we only tossed in a tiny bit more fuel on that one to test the sequential setup for fun and leveled it out.

no map sensor, you can buy a 3 bar from them or use the stock map sensor on the motor if you are doing all motor

yes,

he is also working on a plug and play version with a wiring harness that will plug right into the stock ****, with a relay and fuse panel.

this i will have to confirm, but he wants to have the option of the cheaper wire yourself deal.

Mike says he will be doing a plug and play harness for around 700 additional, but package price should be 1300 (100 less)

it will have a relay and fuse panel for fans, fuel pump ecu and the injectors/coils and will plug and play.

its a few weeks out though.

he said he has these units and harnesses in stock and ready to purchase though

the ecu and wire yourself pigtail 8ft one.
