Syvecs on a 1M stage 2 pure turbos and supporting mods for 2yrs. Never missed a beat and gets better with constant refinements as I have time to log/analyse/learn.
I was running stock ecu and Bootmod custom tune but got sick of the constant ecu faults and codes so sacked it. You’ll need a lot of experience and knowledge of the syvecs platform to get the best out of it. My drivability is buttery smooth, start up perfect, low speed manners impeccable, AFR control superb. On boost the car a beast for a street car. Knock and traction systems are amazing. I run 22psi on 98RON 26psi on E80 with full flex fuel mapping. Full secondary port control is quite easy but control of stock DI pump is tricky and the base map is not good. Need a fair amount of PID tuning for it to be stable. Also, base map boost closed loop map needs work but once setup it really is very good indeed. All sorts of custom maps and limp failsafes possible that have saved me many times and it’s important to set these up first! Rolling anti lag and normal anti lag easy to set up. Flat shift great for holding boost between changes, launch is amazing (but complex to understand and set up). I also have and EGT probe is each bank that can reduce timing reduction strategies during torque control if temps get too high.
I also have their GPS/MRU primarily for use with their lap analysis software and this also feeds the ecu live G’s and all the other parameters. I use yaw mapped against traction and speed for Traction Control. You can also use GPS as a ground speed ref for traction but usually only needed for drag cars that lift their front wheels off the ground. 12 Cal positions integrated into the cruise up/downfor any combination of boost curve/traction set up/Anti-lag, fuel and timing mods etc etc. cruise still works and you map how it works. Integrates with CAN quite well. t is extremely powerful and still retains all of the features from its Life Racing Motorsport roots (used in top level professional motorsports, Syvecs are the road going branch of LR). No licences or locked out shit. It has amazing closed loop lambda tuning capability (and it does need some tuning). Only additional option is full air shift sequential that needs a flag enabling (few hundred). Suggest if you are not going to get your own hands dirty refining the base map you go with a dealer who can help you.
One grip I have is you can’t reset the service flag without plugging back in the stock ECU but not a big deal.
I also run syvecs in a gt25-660 heavily modded 3cyl GR Yaris and it’s awesome.
Not for everyone, is expensive and a steep learning curve but I have enjoyed the learning.
