I read an article awhile back that stated that cracking ecu's and offering tuning on them is illegal without toyota's permission due to legality reasons. I'd tread lighty. someone can correct me if i'm wrong.
If this turns out to true by either Vivid or RR Racing perhaps both which form of forced induction which would be better setup for ISF S/C or Turbo single or Twin. I know you can make more hp and Tq with Turbo setup. Im coming from more stock internals setup which would be safer setup, more reliable. Which would potentially cause the least amount of stress on stock motor. I do understand that turbos or more efficient than S/C as well. I also know the amount of boost you dial in has a lot to do with this question, but assuming you run low boost on both 6lbs to 8lbs of boost with S/C and 14lbs to 18lbs turbo
Opinions guys which way would you go S/C or T/C?
In reply to all the posts we are seeing, let me say the following:
(1) Will we introduce an ECU tune very shortly?: 100% yes. ECU's will have to be mailed to us, we will ship them back same day we receive them. Turnaround will be very fast. If you want proof, the picture below is an ISF ECU that is setup to be bench flashed:
(2) Are we working on a forced induction option? 100% yes, we expect to be up and running by March. We are about 50% there (supercharger), and have designed the entire drive system, which will be superior to HKS, Icode, I promise. We are currently working on finishing up the ECU tuning, remapping the ISF ECU for a larger MAF which will allow us to push over 600hp. Additionally, I will say right now that anyone purchasing our tune now will get full credit towards the supercharger once that is introduced.
(3) Companies like Alientech are selling the "protocols" and hardware to write to the ECU. Defining the maps, re-calibrating them, and figuring out the functionality of each map in order to effectively and reliably tune the car is up to the tuner.
(4) Without getting into the specifics of tuning the ISF... those of you who have spoken to me know that I am very skeptical of dyno results for headers, intakes, etc... I think it is very easy to intentionally skew or mistakenly misinterpret the numbers. Also, the notion that you can slap an ISF to a dyno, re-flash the ECU, and do before/after dyno comparisons is simply not going to work. After you make changes to this ECU, it takes a significant amount of driving to stabilize the ignition timing and AFRs. You cannot do all the work on a dyno.... and that's why its taking us so long to finalize and prove our tune.
If anyone has Toyota Techstream datalogging software and is willing to beta test for us, please PM me. I want this tune to be as much a collaborative effort on ClubLexus as possible. That way everyone is in the loop, we are being 100% honest and transparent about the results, and we get this done right!

Sounds good. Hoping for the best. At least you dont call the skeptics idiots. Lol ..gotta love Vivid :/
