DIY - Door Handle LED mod
Try and reset your ecu after every mod you make, especially after any engine mod.
this is taken from a UK hyundai site. Resetting Your ECU (Engine Control Unit) Hyundai cars are designed to be driven in all areas of the world, by people of all ages and levels of experience and sophistication. They are set to operate at all altitudes and temperatures and to use fuels of varying octane-rating and purity. Unsurprisingly, the electronic engine control unit of your vehicle has been pre-set to a `one-size-fits-all` state of tune. Whilst the ECU has the capacity to adapt to the owners driving-style to a certain degree, the base-settings are extremely conservative and Hyundai's are famously set to run rich! Most owners would naturally suppose that this situation is something over which they have no control, this is not the case. This document will instruct any owner on how to change the ECU settings of their car, without the alterations being detectable by the Dealership, the Insurance Company, or indeed having any effect on the vehicle's warranty. The operations described are recommended as a first step after taking over ownership of the car, after carrying out any performance modifications, or after any temporary change in the way the vehicle has been used ( i.e. city-bound use, towing etc.). Firstly bring the car to normal operating temperature by driving for 15 minutes or so. Now open the bonnet and disconnect the earth lead from the battery, ensure this is not touching any part of the bodywork - insulate if necessary - and wait 5 minutes. Next switch on the ignition and depress the foot brake for 20 seconds - this will completely discharge the ECU's capacitors via the brake lights. The next step (to be carried out immediately, while the engine is still warmed-up) is to carefully re-connect the battery earth lead, close the bonnet and now drive the car in a spirited fashion (accelerating rapidly through the gears, full-throttle straights etc. etc.) for a full 30 minutes. Try to choose a quiet time on the roads for this, (i.e. early on a Sunday morning!). This period of driving will `re-educate` your ECU into adopting more aggressive timing curves and alter the fuelling to match. It will also allow the unit to recognise any modifications you have made and to react accordingly. If, on the other hand, you are not interested in outright performance, but are more concerned with economy and flexibility, use your normal driving style during this 30-minute run! |

ok... that seems easy.....but I wannna know if anyone did that and made a better time in the 1/4, o you got more HPs in the dyno.....
anyone?!--- thanks |
Re: 1000hp RD2
Not sure if anyone is going to dyno there car before and after resetting the ECU. It is just something easy to do and it will help your engine adapt to your mods and driving style.

Re: AirRAm+Strutbar=DONE!!
You can pull the ECU fuse as well instead of disconnecting the battery.

Its right there in the first post. Its not a difference of "whats best to do", its just your preferance. Battery is more accessable. |
Re: Technical intercooler question.
For just pulling the ECU fuse do you leave it out for 15 min and do the brake light?

Re: oil temp probe placement
hmmm... good question there. If you are disconnecting the battery and then turning on the brake lights... is disconnecting the ECU fuse going to discharge the capacitors in it?

Earth lead
Is the earth lead refering to the pos+ or neg-?
|
earth is negative.. or "ground"
