I couldn't find a lot of info about it, I only know about Unichip that works with it.
But my friend said, there's only one tuner for Unichip and he always play safe and don't want to push the limit of the ECU as he wants to keep his reputation.
Any idea about other ecu modification can be done? I heard that piggyback is useless. So which one will work best for this ecu?
Standalone? If yes which 1?
Really getting sick with my SVDO, have to rev frequently to remain the power.

Oh, so do you know normally SVDO do what modification?
I mean, something that is worth for the performance given.
Like what my friend said, Unichip tuner don't push the ecu to the limit and so the bhp that can be squeezed is very limited also, don't know it's true or not.
Any other standalone ecu to recommend?

QUOTE(maddriver @ Apr 27 2009, 08:14 AM) a stand alone ecu is only as good as the tuner who tunes it....... what mods have u done so far? Not much of modification, -HKS drop in air filter -10.0mm spark plug cable -iridium spark plug -mivec extractor -pivot blue raizin Actually I have reach the torque that I am looking for, but the problem now is that I need to rev the car hard frequently to maintain the performance or it will become torqueless and less responsive.  Sigh.. |

QUOTE(the_catacombs @ Apr 27 2009, 01:52 PM) such mods does not require a standalone ecu... if there are other possibility, dont waste so much money investing a standalone ecu... unless u going to have bigger upgrade soon.... The problem now is that without modifying the ecu, the car will perform like no modification has been done after some time and have to rev hard frequently to bring back the power.   |
