Outputs
The FET and IGBT places on the board can be assigned with much freedom. See GenBoard/Manual/DigitalOut, GenBoard/Manual/DigitalOut/Table
- injectors => injector outputs
- ignition => ignition outputs (logiclevel for active coils; IGBT based power outputs for passive coils)
- bipolar stepper (if used) => stepper outputs
- other outputs => after assigning the above use the remaining outputs. take care about current rating and flyback protection (eg. WBO2 second channel FET and DPAK "extraFET"-s have no flyback installed by default!)
- Use the higher current stuff first for more safety
- except for (low current like) LEDs (like shiftlight), where p259 outputs are the best
- don't forget flyback and GND and GND5 connections
See InternetHorsePower - Not sure why you made this comment but, Javad is the owner of http://www.034motorsport.com and he's well known in the Audi tuning circuits. He's very professional and
- I have no doubt that his numbers are genuine, he knows and lets us know exactly the factors playing in to his dynoing numbers. See http://www.motorgeek.com/phpBB2/viewtopic.php?t=8814
- apparently there is no sufficient information to confirm or deny the numbers
- true, but usually there never is to confirm to 100%. if you read a couple of posts down there are comparisons with stock and chipped cars, as a guideline.
- does his 400m time confirms his published HP?
- He doesn't have any recent times, and 402m times have many variables playing in (drives skill/technique, windspeed, road surface etc), so it's not always a good comparison.
- anyway don't expect to easily build a 599 WHP (btw does he really mean whp? or write whp and mean estimated crank hp?) 20VT and run it reliably for long
- Javad's engine is fully built, that's partly why it has held up with more than 500-600whp for 2 years. Also tuning is a big factor when it comes to reliability, and he has a lot of experience with this. Yes he means 640hp at the wheels, as measured by the dyno with no multiplier applied.
- apparently there is no sufficient information to confirm or deny the numbers
- Anyway this isn't very relevant since I'm not building the engine to make huge HP numbers, I just want a good mechanical basis to apply the GenBoard to.
- good
- I saw that you're doing a similar project, nice. I've done a lot of research on this, and I'd be glad to share info and experience.
- good
Q: Is there any benefit in replacing the SMD transient suppr. diode with the big one in Resc1?
- NO. Don't apply reverse supply voltage (or >15V) anyway.
