Congrats on the timings.

What did you guys do, after removing the catcon? how did you replace that missing length?

Fortunately for some people like me these married uncles dont need any notice more than a few hrs to make such long trip plans. They love living life on the edge most of the times .

The cat con very much exists, its only for show though. Empty on the inside .

Haha,couldn't put it better myself..You guys are insane Raj
But I may become like that myself now (not the married part though) that the pete's & green filter is going in my Elantra today evening. May just drop in on you guys
BTW my two cents is, be careful if you can't get a backup of the existing map.Sounds very risky in that case.

Man I love this thread already!

i suspect that the RD unit is universal type. will go with any CRdi unit!
irrespective of the ECU generation..


The RD units are universal. Installs onto any CRDI system.

As a policy, we do development and testing only on our internal cars (even if it means delays or buying cars for that purpose ), hence the delay

Karthik, a small doubt. Can your diesel ECU control an electric servo actuated VGT?

Oh! OK, thought as much, I was trying to retain the catcon for use later if necessary. will need a full turboback system designed for that. So the wait continues for me.
If that doesnt work out, I'll have to fallback on your cheap and best method

Catcon in a diesel doesnt really do much does it? I mean, it is not as essential in emissions control as it is in petrols, right?
Did you guys do anything about the muffler?

Any plans on blocking off the Exhaust gas recirculation?

@karthik- has testing been completed for the swift? Is the ECU available to buy?

As a standard option , no.. But if it is for your custom needs, then yes.

Does this mean that we dont require boost controllers for VGT cars like getz crdi to increase the boost if we are using your ECU? or am i wrong here.

Yes that is what it means. The boost can be controlled by the ECU itself.

Sorry that is wrong the ECU can only control the VGT function for the actuator and not the boost. The VGT only help get to the boost quicker by adjusting the vances inside the turbo. You would still need a boost controller for VGT enabled cars.

Yes but you can also control boost by keeping the vane angle small even at high RPM. If you don't increase the vane angle then there will be little boost.

How does Variable Turbine Geometry work?

guys!! the main advantage of a VGT is that is eliminates the need for a wastegate! hence boost controllers are typically useless for VGT

do refer the WIKI link on the VGT..
Variable geometry turbocharger - Wikipedia, the free encyclopedia

the ECU does that already. we can control it through the ECU ( no need to fool the waste gate giving it fake input signal..)

yeah will see what turns out in banglore! will bring along my potable disk.

@ karthik. thats great then it should be possible to have more than one map reloaded into the piggybac right. 3-4 mods should be possible. ( economy - city - aggressive and custom) and ok off the record if you want the EDC16 and EDC17 documents i have them alright

well the 50-60 % power gain is no myth! its possible. the internals mainly the turbo is to be taken care of. the VGT units of both Sonata transform and the Captiva enable a stock tune of 150PS( a simlple tuning box will give these engines 170PS+!!) and yes these have EDC16 units which helps them more or less achieve euro4 or 5 regulations. and yes the exhaust and inlet is different.
but not out of reach of the masses.

heck the stock FGT of the Magnum produces a 30kgm torque and 121ps of power!
and @above guys tried using better oil! it will be enable free revving to an extent the vehicle will definitely become more smooth!
co-ordinate with RD and that would be possible.
and yes RD should be having the resource to back up the stock MAP of the elantra.

and for the FIAT Fanatics i know how to flash them hehe.

its too tedious a process you will mainly need three files.
.idx, .PRm, .bin if these three and a CAN -CARD -XL with a Dianalyser software is available you can flash any fiat ecu!

am currently doing a hyundai VIVA test(meg17.9.12) some gasoline ECU sorry cant let out more details.

just cant wait to get my hands on the R-series engine ECU..

cheers

Pardon my limited knowledge, but does it means Elantra is a true performance car which can get atleast 40-50% boost of it original capability just with a Pete Box, A free-flow Air Filter and a Racedynamic ECU ??

You might have to read again am quoting from Wikipedia

"In many configurations, VGTs do not even require a wastegate; however, this depends on whether the fully open position is sufficiently open to allow boost to be controlled to the desired level at all times. Some VGT implementations have been known to over-boost if a wastegate is not fitted."
