The Hell Moose Performance LLC VolSquirt ECU is for all 94-98 850, 98 S70 & V70 and 96-98 960 & S90 & V90. This ECU is based on Megasquirt 3 Pro, which is a proven, well adopted and well supported aftermarket engine management solution. Our ECU uses a Megasquirt 3 Pro Daughter board and a custom designed motherboard to adapt all OEM system functionality and make the system fully plug and play. The ECU uses the stock connector and case so that one doesn’t have to do extensive wiring modification (or design a completely new harness) in order to adapt the power of an aftermarket engine management system. It provides a vaccum port for it's built in MAP sensor a USB B connector for communication with TunerStudio and a 24 pin and 12 in external connector for additional functions further described in the manual.

Simply remove your old ECU, install this new one, wire in a GM IAT into your cold side IC piping and wire a analog signal from your wideband and you're ready to go!

The ECU also includes a turn key base tune with everything fully configured to get you up and going as quickly as possible. It is the customers responsiblity to tune the system themselves or find a tuner. We do not offer any remote or local tuning.

This ecu is used on my 800hp Volvo 850 T-5R as well as other big turbo cars!

This item ships in 3-4 business days as we don't current stock the MS3-PRO daughterboards the system relies on.
