Question shat exactly is the 'vishnu method' for re-learning the ECU ?

Hi guys,

I've seen this referred to before, but never an explanation. What
exactly is the Vishnu method for re-setting and then re-teaching
the ECU for maximum performance?

I have been to their WEBsite and found nothing. Can anyone
refer me to something 'official' with some good documentation,
explanations, and a procedure ?

Thanks in advance for any help.

I forgot how to do it, something about coming on part boost and letting off a few times then hitting full boost. Anyway, what it does it advance the ignition advance threshold in the ecu. It's on a scale from 0-16 and 16 being the most aggresive. Stock is lower, so by doing this you set the threshold to 16. If you have good gas and conditions its fine, you get extra power, and if the ecu doesn't agree with the ignition advance, then it pulls back timing accordingly. Of course pulling back from 16-11 might still be higher than your starting point of say 8. This is just a rough explanation. I don't know if it'll work on the sti, and i personally wouldn't do it, but it's up to you.
