* 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.

* 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.

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.

Q: I'm following MembersPage/PhatBob/UserGuide and I've connected and powered up the board to the computer.

* the keyboard/lcd works

* I can work the menus in terminal, say "Man" in TerminalProgram or in the mini-terminal in MegaTune, but when I try to test the connection through Communication Settings it says "No Response!". The settings are as in the userguide.

before trying megaTune

* right after reboot (after powerup, default is binary megatune communication mode)

** tried: no success

* if you can use the menu commands, it's in "Man" mode in which you will NOT be able to connect for normal MegaTune logging / tuning. Try "bye" (again), maybe you need to close the terminal window, etc...did you say "bye" in TerminalProgram (or terminal window) and received "Bye" from the ECM ?

** tried. But: was the "Bye" answer visible ? - Yes it was.

* MegaTune, firmware version ?

** VemsMT1.0.30rc3.zip

** firmware version is 1.0.13

*** mdv : "2005. júl. 5., kedd, 21.13.00 CEST"

*** mdV: "1.0.13"

Solution: These are incompatible. Either

* find an old MegaTune release matching your firmware (unsupported. the shipped firmware is ment for testing )

* or upgrade firmware. The firmware bundled with the MegaTune is often a good bet (but read GenBoard/UnderDevelopment/FirmwareChanges anyway).

* Try another serial cable?

** Does NOT seem to be a problem in your case

* Another computer?

** this can work, if the other computer has a MegaTune installed that is compatible with your firmware ;-)

* MegaTune install location:

** nope, MegaTune is not picky on the install location. This allows you to have several versions installed (eg. always have one -operational- for each install, eg. your customer's cars too)

Thank you for the solution!
