Power modification

Misek_Chipsy · 01-03-2007, 08:21 AM

Im trying to do a power mod by fooling the ECU to add more gas (by thinking the engine is cold (cold air)...

So....i need some info on the temperature sensor....
What resistance does the sensore give at which temperatures?

Save yourself a lot of time effort and money. DON'T GO NEAR THOSE MODS!!!!

They do not make any more power (none that has EVER been VERIFIED on a dyno). The only thing the do is make the vehicle run rich, poisoning the O2 sensors either side of the catalytic converter, and destroying the catalytic converter in the process. (~$300 repair/replace bill at least).

The low down on what they are is a 5 cent resistor, commonly available from Radio Shack, so if your "friends" offer to sell you one for $10-20 (seems to be the going rate), then I would seriously be looking for new friends, as these people ar conning you and robbing you BLIND! (remember the saying, "a fool and his money are soon parted"? Worth a thought around about now...).

Note that I have absolutely nothing to gain from this at all.......

THe only thing you gain is an empty wallet due to all the useless fuel you are gonna use lol.. You dont need more fuel for more power... its a combination of air and fuel. add fuel without adding extra air and well your gonna lose power.

Thank god someone agrees with a bit of logic....Hit the nail on the head.

my little brother did it on his saturn. i told him he was an idiot and he didnt listen to me. it ruined his car and he had to replace his o2 sensor, cat, fuel injectors, and before that he had a loss of about 7 mpg

Ok then the mod is bust....
Oh but i allready took care of bringing more air....CAI + ram air system+ K&N.
Not much power gain but the sound gain is nice....

As for the resistors....i have a bunch of them as well as other electronics...as electronics is my line of work so to speak

Now for more fuel i also mounted larger fuel injector and custom valves + Valve timing contoler....and remapet the ECU
So now im looking a way to get some more power trough electronics.Thinking of DASTEK unichip Piggyback unit (10-15HP -dyno tested) but its expensive... 700€ unit+200€ for map....

Does anyone has some other ideas on what to do to gain some more power?
(dont want to hear about tubo

)

The mod you have made to your intake may have improved the flow of air by a few percent (<5%), certainly NOT enough to warrant larger injectors. There is no way of controlling the valve actuation (hydraulic or direct off cams, with no electrical involvement).

The only electrical "modification" that DOES work is to have the ignition map of the ECU altered and to run the vehicle on higher grade fuel. This is what your Dastek unit sort of does by fiddling the outputs of the injector pulses. Depending on exactly what model Kia you have you may find a similar replacement/altered ECU chip from www.powerchipgroup.com. I have had one of these fitted to my '02 Sportage and it DID make a difference, mainly due to the OE ignition map calibration set for 87 octane, whereas in Australia our lowest octane rating is 91 (same as the calibration chip I bought), which allows the ignition to be more advanced.

Another couple of ECU options you may want to look at, given your background, is the MegaSquirt I Programmable EFI System PCB3.0 - UnAssembled Kit or Wolf Engine Management - Engine Management .

Most ECU/injector setups will handle a few pounds of boost without needing new high flow injectors (up to about 5 psi)

You have listed CAI+Ram intake. well you can only have 1 intake how do you have 2? WHere did you get custom valves??? and who remapped your ecu? Valve timing controller umm never heard of suck a thing....

Dont want to hear about turbo?? well thats how you would get a huge gain...

Misek_Chipsy · 01-05-2007, 08:46 AM

Thanx Damkia

2 1fastkia...
The CAI (Cold air intake pipes) is fitted from begining to the air filter...The replaced sport filter is now placed in a boxlike case which has fi80 opening at the front.... from there the ram air system is fited all the way to the bottom of front bumper....

And for the turbo.... the engine couldnt take it.... the head is lowered for larger compression and the engine couldnt take the compression that the turbo would provide.....as well as instaling the turbo is quite complicated and expensive...

Custom Valves were provided by POL tuning and customized.For the ECU remap i went to DASTEK....where i also tested the unichip....(for the unichip,you can have it on test period and if u are not satisfied,you can return ang have your money back....).The unichip is maped to adapt to all things tuned on the engine,so best thing is to get it LAST....

Not heard for valve timing controler?
Well u can check:
Honda - V-TEC -Variable valve Timing and Electronic lift Control
Mitsubishi - MIVEC-Mitsubishi Innovative Valve timing Electronic Control
and etc.

This mod was done at Gabrek....

1fastkia · 01-05-2007, 09:13 AM

Yes on vtech engines but our continuous variable valve timing is done throguh the ecu and cant be cahnged... (why would you wanna change the timing if it is a continuous sytem?)Its not like hondas variable or mitsus its continuos, theres is set at a certain rpm whereas ours is all the time...
Spectras have been boosted by ppl check out cardomain.. there are at least 10 ppl with rios, spectras, sephias that are boosted and can take it, and have. Theres a rio guy on here that is boosted with no problems.... Check him out...
