just a little fyi for the 1.6t gamma guys. Kia has been slowly updating and replacing parts on our cars to fix some factory issues.. one of the latest has to do with MAP sensor replacement and new ECU re flash.. it seems when you take your car in for service here in the states kiais updates the Ecu software and replacing the Map sensor..this seem to be fixing a lot of drivability issues.. with throttle tip in that dip in power that we have found in alldyno runs from thegamma 1.6t. At (4500rpm)either in theVeloster, Optima 1.6 and a few state sideSUV that both kia and Hyundaiput thismotor into.. so it seems Kiais now putting the Map sensor from theOptima ( k5)2.0 Turbo..the new sensor seems to have a better dynamic range and is able to readboost and vacuum more accurately than the old sensor. its seems that when kia fist developed the motor for the velosterit was only rated at 180 hp.. and so the small intercooler and intake andturbo and supporting cooling and oiling system were alldeveloped for that18- HP rating.. well where the car was being induced to the states and The EU..the added weight ofthe us spec bumpers andheaver seats needs to support the air bags made the car no faster than base motor.. so Hyundai.. turned up the power buyremapping the ecu to allow for short command boost levelsof 18 to 19lbs. with sustained boost levels of 10 to 14 pounds.. the mapsensor andwith this new higher boost levelseems to be at the top end of its usable range.. and sometimes default to a closed map sensor.. itswhy the 204HP gamma 1.6tis soo heat sensitive both hot andcold.. and boost seems to be cut a lot. even in normaldriving..
The NewUSElantraSport turbohitting the market.. it seemsall these updates have be incorporated in to the new motor.. bigger intercooler.. larger turbo and the New Map sensor and ecu reflash.. we have actually dyno tested the new 204HPElantra sport and found it actually make a lot moreHp to the wheels.. its makes about 190HP to thewheels wile our cars rated at the same hp level make about 160 to 170.. so Hyundai is under rating the motors.. now..
so Long story short.. you can getthe better power curve with the map sensor update.. we have foundabout a 10 hp gain.. and better overall throttle control andpower curvewith this part..its about 30 to 70 usdollars.. comesstraight form the kia parts counter.. all you have to do is take the old part out put the new one in.. disconnect your negativebattery cablefor about 10 minuets.. put it back on.. now here is the how the computer learns the new part..( this should also be down with any newaftermarket performance part on this platform) get in the car make shure all the doors are closed the windows are up andlights radio are off.. hit the start button but don't depress the clutch just let the gages sweep and yourdummiy lights turn off.. some willstay lit.. wait about 2 minuetsthen car off and restart itwith the clutch depressed like normal.. let itidle down.. and youshould have abetter running car.. with a little more power and just a better driving experience..
