Paul Hassell reacted to Richard Hill in Supercharged Lexus 3UZ
I've just started building a custom 1UZ VVTi loom and specced an ECU for a customer replacing the standard setup (in a Triumph Stag), and with an Xtreme we quickly ran out of aux outputs. The build is now going to use a Thunder.
To run the standard engine functions as implemented on the LS400, it will take at least 12 Aux outs from my calculations:-
VVT Bank 1
VVT Bank 2
Ethrottle Clutch (PWM 250Hz)
Check Engine Light
Oil Pressure Warning Light
Fan (Viscous on LS400, but I like to add electric for any conversion)
Adding Dual Lambda for both banks into the equation (and 3 axis accelerometer, high speed digital inputs, etc.) it quickly makes sense to go for a Thunder.
Paul Hassell reacted to Adamw in Supercharged Lexus 3UZ
Yes we do! We have one as one of the donkey engines on our dyno. The Storm would be my suggestion as for the minimum ECU to go for - 3 main reasons:
The Storm is our lowest cost ECU with Knock control.
The Storm is our lowest cost ECU with 8 injector and 8 Ignition drives.
The Storm is our lowest cost ECU that can drive the stock stepper motor idle valve.
There is a comparison table on this page here to highlight the main differences between our ECU models: https://www.linkecu.com/products/ecu-comparison-chart/
Paul Hassell reacted to Scott in New Storm G4+ "Black" ecu with 8 inj, 8 ign ++++
The G4+ black storm has 2 knock inputs. The main differences (compared to G4+ Xtreme) are less analog temp inputs, less analog volt inputs, less Digital inputs, less auxiliary outputs, and no on-board e-throttle.
