Message: <blockquote data-quote="zaki" data-source="post: 1892530" data-attributes="member: 1051">unichip version Q, correct me if i'm wrong that the unichip is almost the same as e-Manage; Map sensor `cheater' + ignition modifier.I would like to share my experience with e-manage. still fresh from doing a turbocharged civic last week, I found that e-Manage is a good unit especially if you have bolt on turbo kit. the car was a 4 door civic, 1.6 litre single cam no VTEC. td04h turbine + vr4 intercooler + e-Manage + auto gearbox + 0.6~0.7 barthe only problem I have is that I have no idea what kind of ignition map (max timing etc) the car has, since it is the MDM not JDM :regular_smile:.Honda ECUs will show CEL when the MAP sensor detects positive boost, eventhough the MAP tensor capacity is 1.7 bar (absolute). To `disable' the CEL, I need to cheat the ECU, whenever the car goes positive boost e-Manage will give signal as if the car is at WOT (~atmospheric pressure ~ 1 bar (abs) aka high vacuum).As boost climbs up, more fuel and less ignition are needed. The ECU still sees high vacuum (e-Manage cheat laa) whereby the engine is already at positive boost. The fast way to correct this is by raising the adj fuel regulator pressure or swapping to a bigger injector. let say, the injector is too big, then you have to `reduce' fuel at high vacuum column. but wait a minute, if you `reduce' fuel at high vacuum column, won't it increase the ignition? do we know how much ignition is added? much worse, at full boost the car has enough fuel but the ignition is higher that the high vacuum ignition. There you go...luckily the e-Manage can manage the ignition and it is based on MAP sensor. sigh. but then again, do we really know how much ignition to be retarded? right now I feel retarded.....:confused_smile::retarded:so far the car runs better than before and no signs of knock can be heard...</blockquote>

Altezza's my next car!

Hey fellas!

Was wondering what current prices and availability are for Altezza's currently? A nice 210bhp IS200 in white would be lovely. :D
