Krzys Posted April 8, 2013 Share Posted April 8, 2013 The best way to find out is do it on a dyno! Do a run, do the ECU reset and then do another run! Might not create any extra bhp but I think it could affect the throttle response and possibly help with flat spots? Quote Link to comment Share on other sites More sharing options...
Mr Brown Posted April 8, 2013 Share Posted April 8, 2013 As an ecu is a computer i look on it the same way. If you add or change a component on a computer it obviously needs to be restarted to recognise it and depending on the difference in performance that the upgradegives you you may notice a small difference as it will just use standard basic settings and in the case of the ecu that would equate to oem On a pc to get the optimum performance from your upgrade you have to go into the bios to set it up to your needs and with our ecu's we get them remapped to our personal preferences then you notice a big changeSo i say that if you add say a better air filter system or a larger bore exhaust and just reset the ecu it is going to notice the changes but can only set itself up to for want of a better word basic settings so you may or may not noticea difference depending on if your upgrade is working within the parameters that honda originally programmed into the ecu Quote Link to comment Share on other sites More sharing options...

NIKH25 Posted April 8, 2013 Share Posted April 8, 2013 I am on this thinking ,do not get me wrong if it feels good on the bum dyno then thats good hell I put 99ron petrol in all the time to me it feels like I have 20 bhp more so that's fine Back to the reset I would say If you was to run a dyno test you would see no diff ,it would be like flashing your ecu and you can not do that coz mapping ,flashing are all about new map parameters written with a fair bit of work to get them right singing together for opti use and performance .but if people think its done something that fine just want to get the true facts nothing but the facts mam I'm sure Rich @ Dynodaze has seen improved results on the same car running normal unleaded then vpower. I think the ecu does learn and make changes as you say from the sensors as you go, but as you also said a reset puts it back to factory, it then relearns from the environment what settings it needs.

DAVEMB2 Posted April 9, 2013 Author Share Posted April 9, 2013 X2 Be good to get the full facts on what it does or does not do and if it make any diff Quote Link to comment Share on other sites More sharing options...
Krzys Posted April 10, 2013 Share Posted April 10, 2013 Well the job of the reset is to put all the figures in the ECU back to 0 but the effect is what you're looking for the answer to! Quote Link to comment Share on other sites More sharing options...
