sure will buzz you
and about the dyno run. heard that good ol Peter is getting his own Dyno
and by the way what is the details on the KWP2000 unit.
pretty simple set-up but make sure you guys know which parameter to alter!
just make sure. none of the DRY running patterns are altered. its the basic thing that ensures actuators are set to off! if the engine is made to run in overload! ( this is what all the mod chip manufacturers call as fail safe mechanism) the ground rule is 20-40% gain for the mod-chip( tuning box) because only some signals to ECU input can be altered( mainly amplification and widening of input pulse signal! ) but in a Remap 40-45% with stage 1 seting no need of moding internals. here the whole set of parametrs can be changed( not the fooling the ecu with false inputs. the actual input signal is altered from source.!)
anyways the guys doing this will be tech jargons whoam i kidding huh lolz.
all the best for that. need any helps feel free to ask.
and yeah hoping to meet hellstar time time..
and hey is this the KWP2000 unit which will be used?
the one used off the diagnostic socket( aka OBD socket under the steering in case of verna?? not sure of the elantra.) this would mean that the actual series ECU will be used. its bit risky since the actual ECU code if lost, then coming back to stock will be a nightmare!
the best bet would be to get another ECU roughly 10-15k rs. better yet try to get one from a crashed and written off elantra hehe.
and then remap like you desire and hook this ECU in. most probably the elantra will be having a EDC15C2 series ECU which can be handled by the KWP2000
read and write is possible.
and yes any ideas on how to get the remapped codes??
there is a real hard way to do it. reverse engineering.
read the original ECU hex and create a DCM file from it. using INCA if you guys have it.
and search for the _C paramaters which you guys want to change. and change them to desired value. just a proper understanding of the EDC15 Progrmmers Docu is enough you guys will know.
dont ask me that thing has all the parameters written in german!!
EDC15 is speed based. and EDC16 is torque based. in EDC17 everything is in english.
EDC15C2 is used in 1.5CRDI accent and the Elantra2.0 CRDI and the tuscon.
just one thing please dont do anything that will fry the ECU see if the ECU has a boot sector if it does then it will be a safe bet to try something crazy. lolz.
still try to get the remapped files first.
the basic technic is to alter the FMTC and Energization maps!
these two work in a closed loop system.
the Feul Mass Torque Converstion Maps gives an output which is taken as the input for the Valve energization Maps! and yes the Input for the FMTC maps are the Driver deamnd and the ETS(engine torque structure) paramters.
the funda is the driver input say 200Nm torque is required, at the wheels.
so the ETS takes into account the losses at different stages. namely (Engine-flywheel -clutch-transmission-drivetrain) let this be "X"Nm( this is always as % of total torque produced i.e it depends on Y also!) and addtional torque requirements like the ABS unit, AC unit, Different motors and pumps! let this be 'Y" Nm and gives an input to the FMTC to
energize the valves so as to give 200 NM + Y torque after a loss of X nm torque. meaning the E-map should be to produce 200+X+Y Nm of torque
so keep in mind to get a 20% increase in output, the simply changing the FMTC map to have all the parametrs amplified by a factor of .2 will imply that the E-Map will be given input to produce 1.2(200Nm)+.2XNm + .2YNm torque which is useless and dangerous as Y is a constant! and X changes as a % of the total torque produced!. meaning just to achieve a 20% increase in output we cant go about changing everything into 1.2 times!
this is why no one fiddles with the FMTC maps.
its a bit confusing i know but still this is how it is. haha.
cheers
