Paul Hassell 2 Report post Posted July 11 Good morning all, We are about to start an engine swap project on a Land Rover Defender 110 where we are going to fit an early Lexus 1UZ (non vvt) with an Eaton 112 supercharger ! Has anybody on here got a 1UZ engine using Link, as we are not sure which ECU would be the most suitable. Cheers in advance Paul. Share this post Link to post Share on other sites
Adamw 390 Report post Posted July 11 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/ 1 Paul Hassell reacted to this Share this post Link to post Share on other sites
Paul Hassell 2 Report post Posted July 11 Great, I have previous experience with the Storm, but am i correct in thinking the Storm does not accept fly by wire throttle ? Share this post Link to post Share on other sites
Scott C 1 Report post Posted July 11 You are correct. The Xtreme is the most economical ecu with ethrottle control. Share this post Link to post Share on other sites

Paul Hassell 2 Report post Posted November 7 Sorry for not posting up for a while, the conversion is now going to use a 3uz, but almost certainly still with an Eaton Supercharger. I think the Thunder will be the ECU of choice....any thoughts on this ? Share this post Link to post Share on other sites
Richard Hill 12 Report post Posted November 7 Thunder would be great. Loads of spare aux outs and inputs, and dual lambda too. You also get built in ECU hold power control. I have a 3uz which I will run with my thunder. Just not sure what car it's going in yet ! 1 Paul Hassell reacted to this Share this post Link to post Share on other sites
Richard Hill 12 Report post Posted Tuesday at 09:32 PM 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 Fuel Pump ACIS Tacho Ethrottle Relay Ethrottle + Ethrottle - 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 2 Report post Posted Wednesday at 07:44 AM Thank you very much @Richard Hill, that is very helpful, I was trying to work out how many Aux outputs I would need. This setup will be a supercharged 3uz but i do not know how to edit the post title ( if that is even possible). Share this post Link to post Share on other sites
